Detailed Description
In the embodiment of the present application, an execution subject of the process is a charging management device installed with a program for controlling battery charging, and fig. 1 shows an implementation flowchart of a method for controlling battery charging provided in a first embodiment of the present application, which is detailed as follows:
in S101, a battery charging request is received, and a bin opening instruction is sent to a battery charging bin, wherein the bin opening instruction is used for controlling the battery charging bin to open a bin door.
In this embodiment, when the user needs to charge the battery, a battery charging request may be sent to the charging management device, and then the charging management device will perform a battery charging response operation after receiving the battery charging request. Specifically, the user may send the battery charging request to the charging management device through the user terminal, or directly generate a battery charging request on an interactive interface of the charging management device.
Optionally, the user terminal may send a battery charging request to a server to which the charging management device belongs, and then the server performs an authentication operation on the battery charging request, for example, checking the validity of the user account, or determining whether the balance of the user account is sufficient for paying the charging operation, and the like.
Certainly, the user terminal may also send a charging management device query request to the server, and then the server pushes the position information of the charging management device closer to the current position to the user according to the position of the user terminal, and marks the position of the charging management device on the electronic map by calling a third-party electronic map application program built in the user terminal.
Alternatively, the user may transmit a charge reservation request to the charge management device, the charge reservation request containing the time for which charging is reserved and the number of batteries that need to be charged. When receiving the charging reservation request, the charging management device locks the corresponding number of battery charging bins according to the number of the batteries to be charged, and sets the working state of the battery charging bins corresponding to the reserved charging time to be occupied, so that when the reserved charging time is reached, the locked battery charging bins do not respond to the charging requests of other users. Preferably, the charging management device may further send charging reminding information to the user before the time of the reserved charging is reached, so as to remind the user to charge the battery.
In this embodiment, the charging management device may be configured to manage a plurality of battery charging bays, and when receiving a battery charging request initiated by a user, the charging management device first queries the operating state of each battery charging bay, determines which battery charging bays are occupied and which battery charging bays are idle, uses an idle battery charging bay as a target charging bay for the user to charge the battery at this time, and sends a bay opening instruction to the target charging bay. After the battery charging bin receives the bin opening instruction, a bin door of the battery charging bin is opened, so that a user can place a battery to be charged into a bin body of the battery charging bin.
Optionally, the charging management device further feeds back charging indication information to the user, where the charging indication information includes an identifier or position information of the battery charging bin, and the user may determine the corresponding battery charging bin according to the charging indication information.
In S102, receiving the state parameters of the battery sent by the battery charging bin, and identifying the working state of the battery according to the state parameters of the battery; the state parameters of the battery are acquired by the battery charging bin when the battery to be charged is detected to be placed in the bin body.
In this embodiment, after the door of the battery charging bin is opened, whether the battery to be charged is placed in the bin body by a user is detected in real time, and if the battery to be charged is placed in the bin body, the state parameters of the battery are acquired. Specifically, the mode of detecting whether a battery is placed in the storage body may be: the base of the battery charging bin is provided with a pressure sensor, when the pressure value detected by the pressure sensor is larger than a preset threshold value, the fact that the battery is placed in the bin body is proved, a bin door of the battery charging bin is closed, and the obtaining operation of the state parameters is started.
In this embodiment, the battery charging bin performs charging and discharging operations on a battery to be charged so as to obtain state parameters of the battery in a normal working state, and sends the acquired state parameters to the charging management device. After receiving the state parameter, the charging management device determines whether the battery is an abnormal battery according to the state parameter. The mode of identifying the working state of the battery may be: comparing each parameter value in the state parameters with the corresponding standard parameter range, if any parameter value exceeds the corresponding standard parameter range, identifying that the battery is in an abnormal state, and executing abnormal processing operation; otherwise, if the parameter values are all within the corresponding standard parameter ranges, the battery is in a normal state, and the relevant operation of S103 is executed.
Optionally, as another embodiment of the present application, the status parameter includes at least one of: battery operating voltage, battery capacity, battery state of charge, and number of charges. Whether the battery is good or not can be mainly reflected by the various index bodies:
first, if the battery is in a normal state, the output voltage is stable and fixed, and is a rated voltage, and if the current source is a rated current, the charging management apparatus can obtain the operating voltage of the battery, compare the operating voltage with the rated voltage, and if the difference between the operating voltage and the rated voltage exceeds a preset threshold, it indicates that the output voltage of the battery is greatly deviated, and recognizes that the battery is in an abnormal state.
Second, the ability of the battery to store charge is also one of the important indicators for determining whether the battery is normal. If the capacity of the battery for storing the electric charge is the battery capacity, the charging management device acquires the standard battery capacity of the battery to be charged, compares the acquired battery capacity with the standard battery capacity, and if the difference value between the acquired battery capacity and the standard battery capacity is smaller than a preset threshold value, the battery is in a normal state.
Thirdly, the state of charge of the battery comprises two values, namely a state of charge SOC1 corresponding to the completion of charging and a state of charge SOC2 corresponding to the completion of discharging, a difference between the SOC1 and 1 and a difference between the SOC2 and 0 are calculated, if any one of the differences is greater than a preset threshold, the battery is identified to be in an abnormal state, and otherwise, if both the differences are less than or equal to the preset threshold, the battery is identified to be in a normal state.
Fourthly, each battery has a certain charging time limit, when the charging time of the battery exceeds a preset time threshold, the battery is indicated to exceed the service time limit, and the recharging is possibly dangerous, so that the battery is identified to be recycled.
In S103, if the battery is in a normal state, collecting charging environment parameters, and determining a charging mode according to the charging environment parameters.
In the embodiment, the charging management device performs the charging operation on the battery only when the battery is in the normal state, so that the occurrence of dangerous situations such as battery capacity leakage, battery explosion and the like caused by charging of an abnormal battery is reduced, and the safety of the charging operation is improved. Before charging, in order to provide a charging mode matched with the battery and improve charging efficiency, the charging management equipment also collects current charging environment parameters and determines the charging mode according to the charging environment parameters.
In the present embodiment, the charging environment parameter includes, but is not limited to, at least one of the following: the temperature value of the battery, the temperature value in the battery charging bin, the currently available maximum power value, the number of available charging power supplies and the like. And the charging management equipment determines the output power, the output current and the charging time for charging the battery according to the acquired charging environment parameters, and then obtains the charging mode of the battery.
For example, since a certain amount of heat is generated when the battery is charged, the higher the temperature of the battery and the temperature of the battery charging chamber is, the lower the output power of the charging is; if the maximum power value available at present is higher, the output power of the charging can be also appropriately increased. Of course, the more the available number of charging power sources, the greater the output power that can be provided for charging.
Optionally, in S104, the charging management device may obtain a model of the battery in addition to the charging environment parameter, determine a maximum charging voltage or a maximum charging current of the battery according to the model of the battery, and then determine a charging mode of the battery to be charged according to the maximum charging voltage or the maximum charging current and the obtained charging environment parameter, thereby considering charging efficiency and ensuring safe charging. For example, for a battery with an output voltage of 48V, the charging voltage is 54.6V at the maximum; and for the battery with the output voltage of 60V, the maximum charging voltage can be adjusted to 67.2V.
Optionally, if the battery is in an abnormal state, the charging management device rejects the charging request of the user, opens a door of the battery charging bin, pops up the battery to be charged, and outputs an abnormal report to the terminal, where the output mode may be displaying in a display interface of the charging management device or sending the abnormal report to the user terminal.
In S104, a charging control instruction carrying the information of the charging mode is sent to the battery charging bin; and the charging control instruction is used for controlling the battery charging bin to adjust the output current of the charging power supply according to the charging mode so as to charge the battery.
In this embodiment, the charging management device generates a charging control instruction according to the charging mode, where the charging control instruction carries information of the charging mode. Then, the charging management device sends the generated charging control command to the battery charging bin, so that the battery charging bin charges the battery according to the charging control command.
In this embodiment, after the battery charging bin receives the charging control instruction, the corresponding number of charging power supplies are turned on according to the charging control instruction, and the output current of each charging power supply is adjusted, so that the sum of the output power of each charging power supply is consistent with the output power required by the charging control instruction.
Optionally, in this embodiment, the battery charging bin collects the charging state parameters of the battery at preset time intervals during the process of charging the battery, where the charging state parameters include, but are not limited to: current charge capacity, actual charge power, charge loss ratio. The battery charging bin sends the charging state parameters to the charging management equipment, the charging management equipment judges whether the battery is damaged or not according to the charging state parameters, if the battery is identified to be damaged, the charging operation of the battery is stopped, and battery damage information is sent to the server so as to inform relevant maintenance personnel to maintain the battery. The charging management equipment identifies whether the battery is damaged or not by comparing each parameter value in the charging state parameters with the corresponding standard charging parameter threshold value, judging whether the parameter value exceeds the standard charging parameter threshold value or not, and identifying the battery as a damaged battery if any parameter value exceeds the corresponding standard charging parameter threshold value. For example, if the charge loss ratio of the battery is large, that is, the ratio between the amount of charge loss and the total input amount of electricity is larger than the standard damage ratio, it indicates that the battery has a leakage condition, and thus it is determined that the battery has damage.
Therefore, the state parameters of the battery to be charged are collected through the battery charging bin, the working state of the battery is determined according to the state parameters of the battery, whether the battery is abnormal or not is identified, the charging process is executed on the normal battery, the charging environment parameters at the current moment are collected, the charging mode matched with the battery is determined, the charging control instruction is generated according to the charging mode, the output current of the charging power supply is adjusted according to the charging control instruction through the battery charging bin, and the purpose of charging the battery is achieved. Compared with the existing technology for controlling battery charging, the method and the device for controlling battery charging have the advantages that the state parameters of the battery are collected before the battery is charged, whether the battery is an abnormal battery or not is judged, only the battery with the working state of the battery being a normal state is charged, and potential safety hazards possibly exist when the abnormal battery is continuously charged due to the fact that the battery is damaged or the using times of the battery exceed the limit, so that the abnormal battery is not charged, the step of monitoring the abnormality is performed before the charging operation, and the safety of battery charging is improved. And moreover, the charging mode matched with the battery at the current moment is determined by collecting the charging environment parameters, so that the charging efficiency is improved.
Fig. 2 shows a flowchart of a specific implementation of a method S104 for controlling battery charging according to a second embodiment of the present application. Referring to fig. 2, with respect to the embodiment shown in fig. 1, a method S104 for controlling battery charging provided in this embodiment includes steps S1041 to S1043, which are detailed as follows:
in S1041, if the charging mode is a busy charging mode, selecting the first N charging power supplies as target power supplies based on the order of the electric quantity values of the charging power supplies from large to small, where the value of N is smaller than the total number of the charging power supplies.
In this embodiment, there are a plurality of charging power sources for charging the battery, and each charging power source has different remaining electric quantity values due to differences in the number of times of use and the length of use.
In this embodiment, if the charging management device detects that the current charging mode is in a peak power consumption period, it may be determined that the current charging mode is a busy charging mode, and an electric quantity value of each charging power supply at the current time is obtained, so as to determine that a suitable target power supply is selected to charge the battery. The charging management equipment sorts the electric quantity values of the charging power supplies from large to small, selects the first N charging power supplies with larger electric quantity values as target power supplies, and charges the battery through the target power supplies. The value of N can be set according to the requirements of a charging manager, and when the value of N is less than the total number of charging power supplies. Preferably, the value of N may be one-half of the total number of charging power supplies.
In this embodiment, the charging management apparatus may determine whether it is currently in a peak power consumption state according to the current power consumption state, that is, the power consumption of the entire system for controlling the charging of the battery. If the consumed power is greater than a preset power threshold, the electric quantity consumption of the whole system is large, and if an idle charging mode is adopted, the whole consumption is too large, so that the number of started charging power supplies is limited; otherwise, if the consumed power is less than or equal to the preset power threshold, it indicates that the power consumption of the whole system is low, and all the charging power supplies can be started to charge the battery.
In S1042, a busy charging instruction is generated according to the power supply identifier of the target power supply source, and the busy charging instruction is sent to the battery charging bin; and the busy charging instruction is used for controlling the battery charging bin to start the target power supply, setting the output current of each target power supply as a first output current and charging the battery.
In this embodiment, after determining the target power sources, the charging management device obtains power source identifiers of the target power sources, where the power source identifiers may be power source numbers or output lines of the power sources, generates a busy charging instruction according to the power source identifiers, and sends the busy charging instruction to the battery charging bin, and then the battery charging bin may turn on the corresponding target power sources according to the battery identifiers carried in the busy charging instruction, and adjust output currents of the target power sources to be first output currents, so that the total output power of the target power sources is consistent with the charging power preset in the busy charging instruction.
In S1043, if the charging mode is an idle charging mode, generating an idle charging instruction, and sending the idle charging instruction to the battery charging bin; and the idle time point instruction is used for controlling the battery charging bin to start all the charging power supplies, setting the output current of each charging power supply as a second output current and charging the battery.
In this embodiment, if the charging management device detects that the current charging mode is not in the peak power consumption period, it determines that the current charging mode is the idle charging mode, and in this mode, the charging management device turns on all charging power supplies to charge the battery. The parameter value of the target battery in the idle charging command can be set as default, and if the battery charging bin detects that the parameter value of the target battery in the charging control command is empty, the battery charging bin indicates that all charging power supplies need to be started; of course, the charging management device may also encapsulate the power identifiers of all the charging power supplies in the idle charging instruction, so that the battery charging bin turns on all the charging power supplies according to the power identifiers recorded in the charging control instruction.
In this embodiment, after the battery charging bin receives the idle charging command, all the charging power supplies are turned on, and the output currents of all the charging power supplies are set as the second output current, so that the sum of the output powers of all the charging power supplies is consistent with the charging power preset in the idle charging command.
It should be noted that, since the number of the batteries turned on in the busy charge mode is small, in order to ensure that the charge efficiency of the busy charge mode is equivalent to that of the idle charge mode, the first output current should be greater than the second output current, and preferably, the relationship between the two output currents may be:N 1 I 1 =N general assembly I 2 Wherein, in the step (A),N 1 the number of the target power sources is,I 1 is the first output current of the power supply,N general assembly Is the total number of the charging power supplies,I 2 is the second output current.
In the embodiment of the application, the number of the charging power supplies is determined to be started by distinguishing the display charging mode and the busy charging mode, so that the purpose of efficiently charging the battery is achieved, the charging efficiency of the battery is improved, meanwhile, the time required by a user for charging the battery is saved, and the use experience of the user is improved.
Fig. 3 is a flowchart illustrating a specific implementation of a method for controlling battery charging according to a third embodiment of the present application. Referring to fig. 3, in comparison with the embodiment shown in fig. 2, in the method for controlling battery charging provided in this embodiment, after generating a busy charging instruction according to the power supply identifier of the target power supply and sending the busy charging instruction to the battery charging bin, the method further includes S301 to S303:
in S301, a first output power output when the battery charging bin charges the battery is monitored.
In this embodiment, in the process of executing battery charging, the charging management device monitors a first output power of the battery charging bin when the battery is charged, and compares the first output power with a standard charging power included in the generated busy charging instruction, and if the first output power is greater than a preset standard charging power, executes the operation of S302; if the first output power is smaller than the preset standard charging power, executing the operation of S303; and when the first output power is equal to the preset standard charging power, the battery charging bin is indicated to charge the battery in the rated working mode, and under the condition, the current output current and the number of the started target power supplies are continuously kept, so that the battery is charged without adjustment operation.
Optionally, the standard charging power may be set according to a maximum power-taking power of an area where a system for controlling charging of the battery is located.
In S302, if the first output power is greater than a preset standard charging power, any one of the target power supplies is turned off, and the output current of the currently-started target power supply is adjusted by a first step.
In this embodiment, if the first output power is greater than the predetermined standard charging power, it indicates that the power consumed by charging is too high, which may cause a power utilization risk or affect the normal operation of other devices. In this case, the charging management device turns off one of the target power supplies that are running, and the selection mode may be random selection, or may select one target power supply with the smallest electric quantity value as the target power supply to be turned off. After the shutdown operation is completed, the charging management device gradually adjusts the output current of the remaining starting target power supply by a first step length so as to make the first output power consistent with the standard charging power.
In this embodiment, if the current first output power is still greater than the standard charging power after one target power is turned off, the output current of each target power is reduced by a first step length; and if the current first output power is smaller than the standard charging power, increasing the output current of each target power supply by a first step length. When it is detected that the first output power is equal to the standard charging power, the adjustment operation is stopped.
In S303, if the first output power is smaller than the standard charging power, selecting a charging power supply with a largest power value from the un-turned-on charging power supplies as the target power supply, and adjusting the output currents of all currently turned-on target power supplies by a second step length.
In this embodiment, if the first output power is less than the predetermined standard charging power, it indicates that the power consumed by charging is too low, and the time required to complete charging the battery is too long. In this case, the charge management device selects, as the target power supply, one of the non-turned-on charge power supplies having the largest electric power value, and turns on the target power supply. And then the charging management equipment gradually adjusts the output current of all the target power supplies which are started currently, including the newly added target power supply and the output current of the target power supply which is started before, in a second step, so that the first output power is consistent with the standard charging power. Note that the initial current value of the newly set target power supply is equal to the value of the second output current.
In the embodiment of the application, the on-off state of each target power supply and the numerical value of the output current are adjusted according to the actual output power, the purpose of accurately regulating and controlling the charging process is achieved, and meanwhile, the charging efficiency and the safety of a system for controlling the charging of the battery are considered.

in S401, a second output power output when the battery charging bin charges the battery is monitored.
Similar to the implementation process of S301, when executing the idle charge mode, the charge management device also monitors the second output power of the battery charge bin when charging the battery, compares the first output power with the standard charge power included in the generated idle charge instruction, and if the second output power is greater than the preset standard charge power, executes the operation of S402; if the second output power is smaller than the preset standard charging power, executing the operation of S403; and when the second output power is equal to the preset standard charging power, the battery charging bin is indicated to charge the battery in the rated working mode, and in this case, the current output current is continuously kept to charge the battery without adjustment operation.
In S402, if the second output power is greater than a preset standard charging power, the output current of the charging power supply is decreased by a third step.
In this embodiment, since the second output power for charging is greater than the preset standard charging power, which indicates that the electric energy consumed by charging is excessive, it is necessary to gradually decrease the output current of all the charging power supplies in a third step until the second output power is equal to the standard charging power.
In S403, if the second output power is smaller than a predetermined standard charging power, the output current of the charging power supply is increased by a third step length.
In this embodiment, since the second output power is smaller than the preset standard charging power, which may cause a charging time process, the output current of each charging power supply is increased by the third step until the second output power is equal to the standard charging power.
In the embodiment of the application, the on-off state of each target power supply and the numerical value of the output current are adjusted according to the actual output power, the purpose of accurately regulating and controlling the charging process is achieved, and meanwhile, the charging efficiency and the safety of a system for controlling the charging of the battery are considered.

Specifically, if the running number of the battery charging bins is greater than the preset number threshold, it indicates that more batteries are charged, and the power consumption of the whole system is greater, so that the battery charging bins are identified as a busy power consumption state; on the contrary, if the number of operations is less than or equal to the preset number threshold, it indicates that the number of currently charged batteries is small, and the power consumption of the overall system is small, so that the idle state of charge is identified.

In S602, if the temperature parameter exceeds a preset temperature threshold, a heat dissipation operation is performed, and/or an output current of the charging power supply is reduced.
In this embodiment, if the charging management device detects that the temperature parameter exceeds the temperature threshold, it needs to take relevant measures to reduce the temperature of the battery charging bin, so as to avoid battery damage caused by overheating and reduce the probability of accidents.
