That is, ensuring that the charging device normally outputs the activation voltage is a basic condition for realizing hot plug of the charger. In the method for implementing hot plug, in the case that the first fault (i.e., the fault caused by the charging device not being connected to the device to be charged) occurs in the charging device, the charging device is controlled to output the activation voltage. Thereafter, in the case where the charging device and the device to be charged in the inactive state are connected (i.e., the charging device does not fail), the charging device activates the device to be charged in the inactive state with the output activation voltage to obtain the device to be charged in the active state. In this way, it is possible to ensure that the charging device normally charges the device to be charged in the activated state. In the implementation manner, the charging device can continuously output the activation voltage under the condition of no power failure (i.e., without turning off the power supply of the charging device) so that the charging device can normally charge the device to be charged, and thus, the hot plug of the charging device can be realized.

1, hot plug (Hot Swap)
Hot plug is also called hot plug, which refers to that a module and a board card are inserted into or pulled out of a system without affecting the normal operation of the system under the condition of not closing the power supply of the system, thereby improving the reliability, the quick maintainability, the redundancy, the timely recovery capability to disasters and the like of the system. For a high-power modularized power system, the hot plug technology can replace a power module with a fault under the condition of maintaining the voltage of the whole power system, and ensure that other power modules in the modularized power system normally operate.
2 Power factor correction (Power Factor Correction, PFC) module
The PFC module realizes that the input alternating current is converted into direct current, and ensures that the input alternating current is in phase with the voltage.
3, relay (Relay)
The relay is an electric control device, and when a change in an input amount (excitation amount) reaches a predetermined requirement, a controlled amount is changed in a predetermined step in an electric output circuit. It has an interactive relationship between the control system (also called input loop) and the controlled system (also called output loop). It is commonly used in automated control circuits and is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, the circuit plays roles of automatic regulation, safety protection, circuit switching and the like.
4, input relay
The input relay means a signal or voltage used by the relay to control the input to the charging device.
5, output relay
The output relay refers to a signal or voltage used by the relay to control the output of the charging device.
An application scenario applicable to the embodiments of the present application is described below with reference to the accompanying drawings.
Fig. 1 is an application scenario of a method for implementing hot plug provided in an embodiment of the present application. Exemplary, the application scenario illustrated in fig. 1 includes: a charging device 100 and a plurality of devices to be charged. Wherein the plurality of devices to be charged includes the device to be charged 200 and the device to be charged 300. It is understood that the battery to be charged is mounted in any one of the plurality of devices to be charged.
In the case where the charging apparatus 100 and the apparatus to be charged (for example, the apparatus to be charged 200 or the apparatus to be charged 300) are connected, the charging apparatus 100 may charge the apparatus to be charged. The device to be charged may comprise a battery to be charged, and the charging device 100 charges the device to be charged, in particular charges the battery to be charged comprised by the charging device 100.
In the embodiment of the present application, the connection manner between the charging device 100 and any two devices among the plurality of devices to be charged is not particularly limited. By way of example, any two devices may be connected by, but not limited to, a cable. For example, referring to the circuit configuration diagram shown in fig. 2B, the charging device 100 is connected to the device to be charged 200 through a charging wire. Illustratively, any two devices are provided with a charging gun interface through which the any two devices may be connected. For example, referring to the circuit configuration diagram shown in fig. 2A, the charging apparatus 100 is connected with the apparatus 200 to be charged through the charging gun interface (i.e., the charging gun interface 106 and the charging gun interface 201).
In the embodiment of the present application, the type of the device to be charged is not particularly limited. For example, the device to be charged may be, but is not limited to, any of the following: lithium battery, smart car, wearable device, mobile terminal, smart phone, tablet computer or server.
It should be understood that the application scenario shown in fig. 1 is merely schematic, and does not constitute any limitation on the application scenario applicable to the embodiments of the present application. For example, the charging device 100 shown in fig. 1 described above may also charge a greater number of devices to be charged or a smaller number of devices to be charged.
Next, the principle of the charging apparatus 100 shown in fig. 1 described above to charge the apparatus 200 to be charged will be described with reference to the drawings.
Fig. 2A is a schematic diagram of one circuit configuration of the charging apparatus 100 and the apparatus to be charged 200 shown in fig. 1 described above. By way of example, fig. 2A shows that the charging device 100 includes: a control unit 101, an input relay 102, an output relay 103, a PFC module 104, a VCC module 105, and a charging gun interface 106. The device to be charged 200 includes a charging gun interface 201.
The control unit 101 is responsible for running a software program and controlling each module included in the charging device 100. Note that the power supply of the control unit 101 does not pass through the input relay 102. That is, the control unit 101 can still operate normally with the input relay 102 open. The control unit 101 may also be configured to perform fault detection to determine whether the current fault is a fault in which the charging apparatus 100 and the apparatus to be charged 200 are not connected, or to determine whether the current fault is a fault other than the charging apparatus 100 and the apparatus to be charged 200 are not connected. For example, other faults may be, but are not limited to: the charging device 100 inputs abnormality, over-temperature, over-current, or the like.
The input relay 102 is a device that controls the power supply of the charging apparatus 100. The input relay 101 may include at least one switch. For example, referring to the structure of the input relay 102 shown in fig. 2C, the control unit 101 may control the on and off of the input relay 102. The input relay 101 operates as follows: in the case where the input relay 102 is closed, a power supply may be provided for the charging device 100 to output a charging voltage, a charging current, an activation voltage, or the like; in the case where the input relay 102 is turned off, the charging device 100 does not output voltage and current; with the input relay 102 closed, the charging device 100 may output an activation voltage. It will be appreciated that the output of the activation voltage does not pass through the output relay 103.
The output relay 103 is a device that controls whether the charging apparatus 100 continues to charge the apparatus 200 to be charged. The output relay 103 may include at least one switch. For example, referring to the structure of the output relay 103 shown in fig. 2C, the control unit 101 may control the on and off of the output relay 103. The output relay 103 operates as follows: in the case where the output relay 103 is closed, the charging device 100 supplies the charging voltage to the device to be charged 200; in the case where the output relay 103 is turned off, the charging device 100 does not supply the charging voltage to the device to be charged 200.
The PFC module 104 is configured to adjust a waveform of a current output from the power supply device, and compensate for a phase difference between the current and the voltage output from the power supply device. Wherein the power supply device is a power supply source of the charging device 100. For example, in some implementations, the power provided by the power supply device may be mains. The PFC module 104 is a reactive compensation circuit that can improve the power factor of the power supply, thereby increasing efficiency, reducing line loss, and reducing energy consumption. PFC module 104 may be comprised of an inductor capacitor, electronics, and a relay. The PFC module 104 includes a relay for controlling whether the PFC module is in an operational state. For example, in some implementations, the PFC module 104 is in an operational state with a relay included therein being closed; with the relay included in the PFC module 104 open, the PFC module is in a non-operational state.
The VCC module 105 is used for providing power to the analog chips and devices on the modules included in the charging apparatus 100. Specifically, the VCC module may power an input relay 102, an output relay 103, and a PFC module 104 included in the charging device 100. The charging gun is used for connecting a charging gun interface 106 arranged on the charging equipment 100 with a charging gun interface 201 arranged on the equipment 200 to be charged. The charging gun is an assembly of wires. In the embodiment of the present application, the structure of the charging gun is not particularly limited. For example, in some implementations, a charging gun may include: a charging line (e.g., two), a communication line (e.g., two), an active voltage line, a signal enable line, and a ground line.
It should be understood that the structures of the charging device 100 and the device to be charged 200 shown in fig. 2A described above are merely schematic, and do not constitute any limitation on the structures of the charging device and the device to be charged applicable to the embodiments of the present application. For example, the charging apparatus 100 and the apparatus 200 to be charged shown in fig. 2A described above may also be replaced with the charging apparatus 100 and the apparatus 200 to be charged shown in fig. 2B. For example, the charging device 100 and the device to be charged 200 shown in fig. 2A may also include other modules, which may be, but are not limited to, a memory or the like, such as the memory may record the charging voltage and the charging current during charging. For example, the charging device 100 illustrated in fig. 2A described above may also not include the PFC module 104.
Application scenarios and structures of the charging device applicable to the embodiments of the present application are described in detail above in conjunction with fig. 1 to 2C. Next, a method for implementing hot plug provided in the embodiments of the present application will be described in detail with reference to fig. 3 and fig. 4.
Fig. 3 is a schematic diagram of a method for implementing hot plug according to an embodiment of the present application. The implementation method of hot plug provided by the embodiment of the application can be executed by the charging equipment. It is understood that the charging device may be implemented in software, or a combination of software and hardware. In some implementations, when the charging device is implemented in software, it is understood that the functions of the charging device described in fig. 3 may be implemented through software simulation. In other implementations, when the charging device is implemented as a combination of software and hardware, the method performed by the charging device described in fig. 3 may be implemented by way of software controlling the charging device. By way of example, the charging device in the embodiments of the present application may be, but not limited to, the charging device 100 shown in fig. 2A or 2B. As shown in fig. 3, the method for implementing hot plug provided in the embodiment of the present application includes S310 to S330. Next, S310 to S330 will be described in detail.
S310, in a case where the charging device has a first failure in which the charging device is not connected to the device to be charged, the charging device outputs an activation voltage.
The charging apparatus suffers from a first failure in which the charging apparatus is not connected to the apparatus to be charged, that is, a failure in which the apparatus to be charged is not connected (i.e., a first failure) is a failure caused by the charging apparatus and the apparatus to be charged being in an unconnected state. In the embodiment of the present application, the cause of the failure that causes the charging device and the device to be charged to be in the unconnected state is not particularly limited. Illustratively, in some implementations, the first fault is at least one of: the fault caused by abnormal communication between the charging equipment and the equipment to be charged or the fault caused by the connection device connecting the charging equipment and the equipment to be charged being pulled out from the equipment to be charged. The connection means is not particularly limited, and for example, the charging device and the device to be charged may be connected by a charging wire, and in this implementation, the connection means is a charging wire. As another example, the charging device and the device to be charged may be connected by a charging gun, and in this implementation, the connection device is the charging gun. Wherein, the charging gun is an aggregate formed by combining wires. In the embodiment of the present application, the structure of the charging gun is not particularly limited. For example, the charging gun may include: a charging line (e.g., two), a communication line (e.g., two), an active voltage line, a signal enable line, and a ground line. It is understood that in the case where communication abnormality occurs between the charging device and the device to be charged, whether the charging device is connected to the device to be charged through the connecting means is not limited. It should be understood that the first fault described in the above implementation is merely illustrative, and does not constitute any limitation on the first fault to which the embodiments of the present application are applicable. In other words, any one of the faults that causes the charging device and the device to be charged to be in the unconnected state may be regarded as the first fault described in the embodiments of the present application.
In the embodiment of the application, the activation voltage is used for activating the device to be charged in the inactive state, which is also called activating the device to be charged. In some implementations, the device to be charged is activated by placing a battery management system (Battery Management System, BMS) in the device to be charged in an activated state. It can be further understood that the activation voltage can also be used as a judging basis for judging whether the charging device is connected or not by the device to be charged. Specifically, when the device to be charged determines that the voltage (i.e., the activation voltage) input to the device to be charged in the inactive state is higher than a certain voltage value (may be a preset voltage value), the device to be charged 200 may determine that the charging device is already connected (note that this is not the basis for the charging device to determine whether to connect to the device to be charged).
The device to be charged is a device to be charged, and the type of the device to be charged is not particularly limited. In some implementations, the device to be charged may be a battery (e.g., a lithium battery or a storage battery). Alternatively, in other implementations, the device to be charged may be a battery in the device, where the device may be, but is not limited to, any of the following: electric car, wearable device, smart phone, tablet computer or server, etc. By way of example, the device to be charged may be, but is not limited to, a lithium battery in an electric vehicle.
The above S310 is performed, that is, in the case where the first failure (i.e., the failure in which the charging device and the device to be charged are in the unconnected state) occurs in the charging device, the charging device outputs the activation voltage. It will be appreciated that in such an implementation, the charging device may not output the charging voltage, which may ensure safety and reduce consumption of power resources.
Optionally, in some implementations, before the first failure of the charging device, the method further includes: in the case where the charging device has a second failure, which is a failure other than the first failure, the charging device stops outputting the activation voltage. In this implementation, in the event that the charging device fails except for the failure in which the device to be charged is not connected, the charging device does not output the activation voltage. In the implementation manner, the charging device is controlled to no longer output the activation voltage when the second fault occurs in the charging device, so that safety can be ensured. In the above implementation, the charging device stops outputting the activation voltage whenever the charging device fails in the second way. It will be appreciated that in the above implementation, the second fault is a fault that occurs before the first fault occurs. Alternatively, in other implementations, the second failure of the charging device may also occur after the charging device performs S310 and S320. That is, in this implementation, the second fault is a fault that occurs after the first fault occurs and the first fault is recovered. In the above implementation manner, the second fault is a fault other than the first fault, and the second fault is not specifically limited in the embodiment of the present application. In some implementations, the second fault is at least one of: a fault caused by abnormal input of the charging device, a fault caused by excessive temperature of the charging device, or a fault caused by excessive current output by the charging device. It should be understood that the second fault described in the foregoing implementation manner is merely illustrative, and any fault occurring in the charging device other than the first fault may be used as the second fault described in the embodiments of the present application.
In the embodiment of the application, the charging device may also have a fault detection function. Optionally, in some implementations, before the charging device stops outputting the activation voltage, the method further includes: the charging equipment performs fault detection; and determining that the charging device has a second fault in the case that the charging device detects the second fault, wherein the second fault is a fault except the first fault. Optionally, in other implementations, the method further includes: the charging equipment performs fault detection; and under the condition that the charging equipment detects that the charging equipment and the equipment to be charged are in an unconnected state, determining that the charging equipment has a first fault. In the above implementation manner, the charging device has a fault detection function, and the charging device can divide the fault occurring in the charging device into two types of faults by performing fault detection, where the two types of faults include a first fault and a second fault.
S320, in the case where the charging device and the device to be charged in the inactive state are in the connected state, the charging device activates the device to be charged in the inactive state using the outputted activation voltage.
The above S320 is continued after the above S310 is performed, that is, in the case where the charging device only fails without being connected to the device to be charged, the charging device outputs the activation voltage. After that, in the case where the above-described failure recovery of the charging apparatus occurs, that is, the charging apparatus and the apparatus to be charged are in the connected state, and the charging apparatus does not occur other failures than the failure in which the apparatus to be charged is not connected, the charging apparatus performs activation processing on the apparatus to be charged in the unactivated state using the output activation voltage, so that the apparatus to be charged is switched from the unactivated state to the activated state.
In the embodiment of the application, in the case where the charging device and the device to be charged are switched from the disconnected state to the connected state, at this time, the device to be charged is still in the inactive state. That is, in the case where the charging apparatus and the apparatus to be charged are switched from the disconnected state to the connected state, the charging apparatus needs to activate the apparatus to be charged in the inactive state to obtain the apparatus to be charged in the active state. Thereafter, the charging device may achieve the purpose of charging the device to be charged in the activated state using the charging parameters corresponding to the device to be charged.
And S330, the charging equipment charges the activated equipment to be charged.
The step S330 of charging the activated device to be charged by the charging device is performed, including: and the charging equipment charges the activated equipment to be charged by using the charging parameters, wherein the charging parameters are determined according to the model of the equipment to be charged, the parameters of the equipment to be charged and the real-time state of the equipment to be charged when the equipment to be charged is charged. The parameters of the device to be charged may include: parameters such as working voltage and working current of the equipment to be charged. Wherein, the charging parameters corresponding to the equipment to be charged include: a charging voltage corresponding to the device to be charged, and a charging current corresponding to the device to be charged. In the embodiment of the present application, the value of the charging voltage and the value of the activation voltage are not particularly limited. In other words, the voltages having the above-described activation voltage actions can be used as the activation voltages described in the embodiments of the present application, and the voltages having the above-described charging voltage actions can be used as the charging voltages described in the embodiments of the present application.
It should be noted that, in the process of executing the implementation method of hot plug provided in the embodiments of the present application, the power supply of the charging device does not need to be turned off. That is, in the process of executing the implementation method of hot plug provided in the embodiment of the present application, the charging device is in a state of no power failure.
It should be noted that, the structure of the charging device and the structure of the device to be charged to which the method for implementing hot plug shown in fig. 3 is applicable are not limited in particular. That is, as long as the function of the charging device described by the method shown in fig. 3 described above can be achieved, the charging device described in the embodiment of the present application can be used. For example, the structure of the charging device and the structure of the device to be charged shown in fig. 3 may be referred to as a circuit structure shown in fig. 2A or fig. 2B. It can be understood that, when the implementation method of hot plug provided in the embodiment of the present application is applied to charging devices having different structures, the charging device may output an activation voltage, stop outputting the activation voltage, or use a charging parameter to charge a charging device, where the working principle of the charging device may be different, and the working principle is not specifically limited in the embodiment of the present application.
It should be understood that the implementation method of hot plug described in fig. 3 is merely illustrative, and does not limit the implementation method of hot plug provided in the present application. For example, the charging device may also first fail a second after performing S320 described above, and then fail a first. In this implementation, the processing flow when the first failure occurs in the charging device is the same as the flow described in S310 above; the processing flow when the second failure of the charging apparatus occurs is the same as the processing flow of the charging apparatus for the second failure described above. As another example, in other implementations, the charging device may also have both the first fault and the second fault at the same time, in which implementations the charging device stops outputting the activation voltage until the charging device outputs the activation voltage after the second fault is eliminated. And after the first fault is eliminated, namely, under the condition that the first fault and the second fault of the charging equipment do not occur, the charging equipment activates the equipment to be charged by using the activation voltage, and then the charging equipment charges the activated equipment to be charged by using the charging parameters.
In the embodiment of the application, the hot plug function of the charging device is realized by classifying the faults of the charging device into the faults caused by the fact that the charging device is not connected to the charging device (namely, the first fault) and the faults except the faults of the charging device not connected to the charging device (namely, the second fault), and performing different treatments when the two types of faults of the charging device occur. Specifically, in the event that it is determined that the charging device is not powered down (i.e., the power supply of the charging device is not required to be turned off) and the first failure occurs, the charging device continuously outputs the activation voltage. In the case where it is determined that the second failure of the charging device occurs, the charging device stops outputting the activation voltage. When the first fault occurs in the charging equipment, the activation voltage output by the charging equipment activates the equipment to be charged, so that the equipment to be charged in an activated state can be obtained. Thereafter, in the case where the charging device does not fail (i.e., the first failure and the second failure do not occur), the charging device may charge the device to be charged in the activated state. In addition, the implementation method of hot plug described in the embodiment of the present application may be implemented by controlling a module or a unit in the charging device through software set in the charging device, and the method does not need to change a hardware circuit of the charging device, so that cost can be saved, and implementation logic is simple and efficient, and does not need to occupy excessive operation resources.
Next, another implementation method of hot plug provided in the embodiment of the present application is described with reference to fig. 4. It will be appreciated that the implementation method of the hot plug described in fig. 4 is a specific example of the implementation method of the hot plug described in fig. 3, and the method described in fig. 4 is only illustrative, and does not constitute any limitation on the implementation method of the hot plug provided in the present application. It is to be understood that the charging device 100 shown in fig. 4 is a specific example of the charging device shown in fig. 3 described above, and the device to be charged 200 shown in fig. 4 is a specific example of the device to be charged shown in fig. 3 described above. The structure of the charging apparatus 100 described by the method shown in fig. 4 is specifically the structure of the charging apparatus 100 shown in fig. 2A described above, and the structure of the apparatus to be charged 200 described in fig. 4 is specifically the structure of the apparatus to be charged 200 shown in fig. 2A described above.
Fig. 4 is a schematic diagram of another implementation method of hot plug according to an embodiment of the present application. The implementation method of hot plug provided by the embodiment of the application can be executed by the charging equipment. It is understood that the charging device may be implemented in software, or a combination of software and hardware. In some implementations, when the charging device is implemented in software, it is understood that the functions of the charging device 100 described in fig. 4 may be implemented through software simulation. In other implementations, when the charging device is implemented as a combination of software and hardware, the method performed by the charging device 100 described in fig. 4 may be implemented by way of software controlling the charging device 100. Illustratively, as shown in FIG. 4, the method includes steps S401 through S412. Next, steps S401 to S412 will be described in detail. S401, the charging device 100 initializes.
Performing S401 described above, i.e., initializing the charging device 100, includes: the charging device 100 completes a basic power-up delay, ensuring smooth operation of the modules and units included in the charging device 100.
It should be noted that, in the process of executing the implementation method of hot plug provided in the embodiments of the present application, the power supply of the charging device does not need to be turned off. That is, in the process of executing the implementation method of hot plug provided in the embodiment of the present application, the charging device is in a state of no power failure.
S402, the charging apparatus 100 determines whether there is a failure other than the failure in which the apparatus 200 to be charged is not connected.
The failure in which the device to be charged 200 is not connected refers to a failure in which the charging device 100 and the device to be charged 200 are not connected. The cause of the failure that causes the charging device 100 and the device to be charged 200 to be disconnected is not particularly limited. In the embodiment of the application, the charging device 100 is connected with the device to be charged 200 through a charging gun interface 106 arranged on the charging device 100, a charging gun and a charging gun interface 201 arranged on the device to be charged 200. For example, it may be that the charging gun between the charging apparatus 100 and the apparatus to be charged 200 is pulled out so that the charging apparatus 100 and the apparatus to be charged 200 are in an unconnected state, resulting in a failure of the unconnected apparatus to be charged 200. For example, it may be that the charging gun interface 106 provided on the charging apparatus 100 fails, resulting in the charging apparatus 100 and the apparatus 200 to be charged being in an unconnected state. As another example, it may be that the charging gun connecting the charging apparatus 100 and the apparatus to be charged 200 fails, resulting in the charging apparatus 100 and the apparatus to be charged 200 being in an unconnected state. In the embodiment of the present application, the device to be charged 200 may be, but is not limited to, a lithium battery.
The failure other than the failure of the unconnected device to be charged 200 is not particularly limited. Illustratively, the fault other than the fault in which the device to be charged 200 is not connected may be at least one of the following: the charging device 100 inputs an abnormality, the charging device 100 overflows, or the charging device 100 is over-heated.
The method of judging whether or not the charging apparatus 100 has a failure other than the failure to which the apparatus 200 to be charged is not particularly limited. In some implementations, the control unit 101 in the charging device 100 is configured to perform fault detection on the charging device 100 to determine whether there is a fault other than the fault in which the device 200 to be charged is not connected. Specifically, the control unit 101 determines whether various faults exist through acquisition and setting. For example, the control unit 101 collects a voltage to determine whether an overvoltage is generated, and the control unit 101 collects a temperature to determine whether an overtemperature is generated. Optionally, in other implementations, the charging device 100 may further include a detection unit, where the detection unit is configured to perform fault detection on the charging device 100 to determine whether there is a fault other than the fault in which the device 200 to be charged is not connected.
In the embodiment of the present application, the charging apparatus 100 determines whether there is a failure other than the failure in which the apparatus 200 to be charged is not connected, including: in the case where the charging apparatus 100 determines that there is a failure other than the failure in which the apparatus 200 to be charged is not connected, S402 is continued to be executed after S402 is executed; alternatively, in the case where the charging apparatus 100 determines that the failure other than the failure in which the to-be-charged apparatus 200 is not connected is not removed, S403 is continued after S402 is performed.
It is to be understood that the above-described S402 is performed, if the charging apparatus 100 determines that there is no fault other than the fault in which the apparatus 200 to be charged is not connected, that is, the fault currently existing is the fault in which the apparatus 200 to be charged is not connected. If the charging apparatus 100 determines that there is a fault other than the fault in which the apparatus 200 to be charged is not connected, that is, the currently existing fault type includes: failure of the to-be-charged device 200 is not connected, as well as other failures. Other faults may be, but are not limited to: the charging device 100 is over-temperature or over-current, etc.
S403, the control unit 101 in the charging device 100 controls the input relay 102, the PFC module 104, and the VCC module 105 to be closed.
After the above S402 is performed, S403 is continuously performed, that is, in the case where it is determined that there is no fault other than the fault in which the device 200 to be charged is not connected, the control unit 101 in the charging device 100 controls the input relay 102, the PFC module 104, and the VCC module 105 to be closed. In other words, in the case where the charging device 100 determines that there is a failure in which the device 200 to be charged is not connected and the VCC module 105 supplies power to the input relay 102 and the PFC module 104, the charging device 100 may output an activation voltage.
The above S403 is performed, that is, the VCC module 105 may supply power to the input relay 102 and the PFC module 104 in a closed state; and closing the PFC module 104 causes the PFC module 104 to operate such that the PFC module 104 is in an operational state. S404, the charging device 100 outputs an activation voltage.
The activation voltage is used for activating the inactive device to be charged 200, so that the activated device to be charged 200 can be normally charged in the case that the charging device 100 outputs the charging voltage. That is, the activation voltage is used to activate the device to be charged 200 that is not activated, and the activation voltage may also be used as a basis for determining whether the device to be charged 200 is connected to the charging device, and above a certain voltage, the device to be charged 200 may determine that the charging device is connected (note that this is not a basis for determining whether the device to be charged 200 is connected to the charging device 100). Illustratively, a 105 amp/hour (Ah) battery used by the charging device has an activation voltage of 50 volts (volt, V) (which may not actually be required), and a charging voltage that is raised to 42-58V following the rise in the battery voltage. The charging voltage refers to an output voltage of the charging device during charging of the device to be charged 200. In practical applications, the charging device 100 also outputs a charging current when the charging device 100 charges the device to be charged 200. In the present embodiment, the charging voltage output by the charging apparatus 100 summarizes the output when the charging apparatus 100 charges the apparatus 200 to be charged. That is, the charging device 100 described in the embodiment of the present application outputs the charging voltage, and the charging device 100 may output the charging voltage and the charging current instead.
After performing S401, S402, and S403 described above, the VCC module 105 may supply power to the input relay 102 and the PFC module 104 so that the charging device 100 may output an activation voltage. In this implementation, since the charging device 100 is not connected to the device to be charged 200, the charging device 100 does not need to output a charging voltage in order to ensure safety, and the method can reduce consumption of power resources while ensuring safety. In practical applications, the device to be charged 200 needs to be activated by the output voltage of the charging device 100, and then, if the device to be charged 200 receives the charging voltage output by the charging device 100, normal charging can be performed. That is, ensuring that the charging device 100 normally outputs the activation voltage is a basic condition for realizing hot plug of the charger. That is, hot plug of the charging device can be achieved by the above method.
S405, the charging device 100 determines whether there is a failure.
The failure described in S405 above is any failure. For example, the arbitrary fault may be: the failure of the device to be charged 200 is not connected. As another example, the arbitrary fault may be: except for the failure in which the device to be charged 200 is not connected. The method for determining the fault described in S405 by the charging device 100 is the same as the method for determining the fault described in S402 by the charging device 100, and details not described here in detail may be found in the relevant description of S402.
In this embodiment of the present application, the determining, by the charging device, whether there is a fault includes: in the case where the charging apparatus 100 determines that there is a failure, S406 is continued to be executed after S405 is executed; alternatively, in the case where the charging apparatus 100 determines that there is no failure, S407 is continued to be performed after S405 is performed.
S406, the charging apparatus 100 determines whether the failure is a failure caused by the unconnected device to be charged 200.
The above S406 is performed, that is, the charging apparatus 100 determines whether the failure is a failure caused by the unconnected device to be charged 200, including: in the case where the charging apparatus 100 determines that the failure is a failure caused by the non-connection of the apparatus 200 to be charged, S404 is continued after S406 is performed; alternatively, in the case where the charging apparatus 100 determines that the failure is not a failure caused by the unconnected device to be charged 200, S411 is continued after S406 is performed.
S407, the control unit 101 in the charging apparatus 100 controls the output relay 103 to be closed, and the charging apparatus 100 outputs the charging voltage to charge the apparatus 200 to be charged.
The output relay 103 operates as follows: in the case where the output relay 103 is closed, the charging device 100 supplies the charging voltage to the device to be charged 200; in the case where the output relay 103 is turned off, the charging device 100 does not supply the charging voltage to the device to be charged 200.
The working principle of continuing to execute S407 after executing S401, S402, S403, S404, and S405 described above is as follows: in the case where the charging apparatus 100 determines that there is no fault other than the fault in which the apparatus 200 to be charged is not connected, the control unit 101 in the charging apparatus 100 controls the input relay 102, the PFC module 104, and the VCC module 105 to be closed first, so that it can be ensured that the charging apparatus 100 successfully outputs the activation voltage. Thereafter, in the case where the charging apparatus 100 determines that there is no failure, the output relay 103 in the charging apparatus 100 is closed, so that the charging apparatus 100 outputs the charging voltage and charges the apparatus to be charged 200.
S408, the charging device 100 determines whether there is a failure.
The failure described in S408 above is any failure. For example, the arbitrary fault may be: the failure of the device to be charged 200 is not connected. As another example, the arbitrary fault may be: except for the failure in which the device to be charged 200 is not connected. The method for determining the fault described in S408 by the charging device 100 is the same as the method for determining the fault described in S402 by the charging device 100, and details not described here in detail may be found in the relevant description of S402.
The above S408 is performed, that is, the charging device 100 determines whether there is a failure, including: in the case where the charging apparatus 100 determines that there is a failure, S409 is continued to be executed after S408 is executed; alternatively, in the case where the charging apparatus 100 determines that there is no failure, S408 is continued to be executed after S408 is executed.
S409, the control unit 101 in the charging device 100 controls the output relay 103 to open, and the charging device 100 stops charging the device 200 to be charged.
Performing S409 described above, that is, the control unit 101 in the charging device 100 controls the output relay 103 to open, includes: the control unit 101 in the charging device 100 controls at least one switch included in the output relay 103 to be in a non-closed state.
In the embodiment of the present application, the working principle of continuing to execute S409 after executing the above 407 and 408 is: in the case where the charging apparatus 100 normally charges the apparatus to be charged 200 through the charging gun, the charging apparatus 100 cyclically judges whether or not there is a failure, and immediately controls the output relay 103 to be turned off if it is determined that there is a failure, so that the charging apparatus 100 stops charging the apparatus to be charged 200 in the case where the output relay 103 is turned off. Next, the charging device 100 may determine whether the fault is a fault caused by the device 200 to be charged being disconnected, and if not, open the input relay 102, PFC module 104, and VCC module 105. Thereafter, a fault recovery determination phase is entered.
S410, the charging apparatus 100 determines whether it is a failure caused by the unconnected device 200 to be charged.
S410 is performed, that is, the charging apparatus 100 determines whether it is a failure due to the unconnected device to be charged 200, including: in the case where the charging apparatus 100 determines that it is a failure due to the non-connection of the apparatus 200 to be charged, S404 is continued after S410 is performed; alternatively, in the case where the charging apparatus 100 determines that there is no failure caused by the unconnected device 200 to be charged, S411 is continued to be executed after S410 is executed.
S411, the control unit 101 in the charging device 100 controls the input relay 102, the PFC module 104, and the VCC module 105 to be turned off, and the charging device 100 stops outputting the activation voltage.
The working principle of continuing to execute S411 after executing S410 described above is: in the case where it is judged that the failure is not a failure due to the unconnected battery, the control input relay 102, the PFC module 104, and the VCC module 105 are turned off, and thus, the charging device 100 stops outputting the activation voltage thereafter. After the VCC module 105 is controlled to be turned off, the VCC module 105 does not continuously provide the power supply voltage to the input relay 102 and the PFC module 104, so that the charging device 100 does not continuously output the activation voltage. That is, after the execution of the above-described S410 and S411 in order, the charging device 100 does not output the charging voltage and the activation voltage.
S412, the charging apparatus 100 determines whether or not the failure other than the failure in which the apparatus 200 to be charged is not connected is recovered.
The above S412 is performed, that is, the charging apparatus 100 judges whether or not the malfunction is recovered except for the malfunction in which the apparatus 200 to be charged is not connected, including: in the case where the charging apparatus 100 determines that the failures other than the failure to which the to-be-charged apparatus 200 is not connected are recovered, S401 is continued to be performed after S412 is performed; alternatively, in the case where the charging apparatus 100 determines that the failure other than the failure to which the to-be-charged apparatus 200 is not connected has not been recovered, S412 is continued to be performed after S412 is performed. That is, the principle of performing the method described in S412 above is: the charging device 100 determines whether the faults except the fault of the device to be charged 200 are recovered, if yes, the process returns to the initialization stage to enter the process again, and if not, the process continues to be circulated until the fault is recovered.
It should be understood that the implementation method of hot plug described in fig. 4 is merely illustrative, and does not limit the implementation method of hot plug provided in the present application. It will be appreciated that the method shown in fig. 4 above describes a specific example of the implementation method of hot plug provided in the implementation of the present application shown in fig. 3 above, taking the structure of the charger 100 and the structure of the device to be charged 200 shown in fig. 2A above as an example. That is, when the implementation method of hot plug shown in fig. 3 described above is applied to a circuit structure other than the circuit structure shown in fig. 2A described above, specific steps of the implementation method of hot plug shown in fig. 3 described above may not be exactly the same, for example, a circuit principle that the charging device outputs an activation voltage may be different, or a principle that the charging device charges the device to be charged in an activated state may be different, or the like. For example, the charging device 100 described above in fig. 4 may also include other modules or units, such as other units may be, but are not limited to, a memory, where the memory may be used to store data related to the method described above in fig. 4. For example, the device to be charged 200 described in fig. 4 above may be, but is not limited to, an electric vehicle, and in this scenario, the charging device 100 charges the device to be charged 200, i.e., the charging device 100 charges a battery (e.g., but not limited to, a lithium battery) mounted in the electric vehicle.
In the embodiment of the present application, the hot plug function of the charging device is implemented by classifying the faults as faults due to the unconnected device to be charged and other faults (i.e., faults other than the fault in which the unconnected device to be charged 200 is not connected), and performing different processes when the two faults occur. Meanwhile, under the condition that two types of faults occur, the existence of the output activation voltage of the charging equipment after the recovery of other faults can still be ensured through the recovery judgment of different faults, and the hot plug function of the charging equipment cannot be disabled. Specifically, in the case where the charging apparatus 100 is not powered off (i.e., the power supply of the charging apparatus is not required to be turned off) and there is a failure in which the apparatus 200 to be charged is not connected, the charging apparatus 100 continuously outputs the activation voltage by recognizing and judging that the failure is caused by the apparatus 200 to be charged being not connected by the charging apparatus 100. In the case where the charging apparatus 100 determines that the current failure is a failure other than the failure in which the apparatus 200 to be charged is not connected, the charging apparatus 100 may stop outputting the activation voltage, and continuously judge the recovery condition of each failure, and when there is no failure or only the failure due to the apparatus 200 to be charged is left, the charging apparatus 100 may recover outputting the activation voltage. In addition, the implementation method of hot plug described in the embodiments of the present application may be executed by controlling a module or a unit in the charging device 100 through software set in the charging device 100, where the method does not need to change a hardware circuit of the charging device 100, so that cost can be saved, and implementation logic is simple and efficient, and does not need to occupy excessive operation resources.
