It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Example 1

According to an embodiment of the present invention, there is provided an embodiment of a fault handling method for a charging system in a vehicle, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different from that herein.

Fig. 1 is a flowchart of a fault handling method of a charging system in a vehicle according to an embodiment of the present invention, as shown in fig. 1, the method may include the steps of:

step S102, fault detection is carried out on the charging system in the vehicle, and a fault detection result of the charging system is obtained.

In the technical solution provided in the above step S102 of the present invention, the vehicle may be an electric vehicle. The fault detection result may be used to characterize that the charging system is in a fault state, and may be fault data of at least one component in the charging system in the fault state. The components in the charging system may include at least a charging gun, a charging device, a dc charging pile, an ac power source, etc., and it should be noted that the components included in the charging system are only examples, and are not limited herein.

In this embodiment, the state of each component in the charging system in the vehicle may be detected by fault in real time, and it is determined whether each component is in a fault state, and if so, the data of the component at this time may be recorded as a fault detection result.

Optionally, a hybrid control unit (Hybrid Control Unit, abbreviated as HCU) in the vehicle is connected with each component in the charging system through a controller area network (Controller Area Network, abbreviated as CAN) bus, and the HCU is used for detecting the working states of a charging gun, a charging device, a direct-current charging pile, an alternating-current power supply or the like in the charging system in real time to determine whether the states of each component in the charging system are normal, if so, a fault detection result of the corresponding component CAN be obtained, and the fault detection result CAN be sent to the HCU through the CAN bus, wherein the HCU CAN also be called a whole vehicle controller.

For example, the HCU may detect whether the charging gun is properly connected, and if so, may indicate that the charging gun is not in a fault state; if the charging gun is not connected correctly, the charging gun can be indicated to be in a fault state, and the data used for representing the incorrect connection of the charging gun at the moment can be used as a fault detection result. Whether the charging device is faulty or not may be detected, and if so, data for characterizing the fault of the charging device may be used as a fault detection result. The method can detect whether the direct current charging pile is matched with the vehicle, can detect whether the direct current charging pile is overtime in communication, can determine that the direct current charging pile is in a fault state at the moment if at least one of the direct current charging pile and the vehicle is not matched or the direct current charging pile is overtime in communication exists, and can take corresponding data representing the conditions as a fault detection result. Whether the power supply condition of the alternating current power supply is abnormal or not can be detected, if so, the alternating current power supply can be determined to be in an abnormal state, and data used for representing the abnormality of the power supply condition can be determined to be a fault detection result.

It should be noted that the foregoing fault detection process and method and the contents of the states of the respective components for fault detection are only illustrative, and are not particularly limited herein.

Step S104, based on the fault detection result, determining the position information corresponding to the fault state.

In the solution provided in the above step S104 of the present invention, the location information may be used to indicate a location where the fault state exists in the vehicle, and may include two location information, that is, the interior of the vehicle and the exterior of the vehicle.

In this embodiment, after the fault detection is performed on the charging system in the vehicle, the fault detection result of the relevant component in the charging system in the fault state is determined, the fault detection result may be sent to the whole vehicle controller, the fault detection result may be collected by the whole vehicle controller, and the fault detection result may be identified to determine whether the fault state is outside the vehicle or inside the vehicle at this time.

Optionally, the fault status of each critical component of the charging system is collected by the HCU, identifying whether the current fault is a vehicle external fault or a vehicle internal fault. For the external fault of the vehicle, the driver can be timely reminded of replacing the charging equipment, so that the charging function is restored when the charging condition is met again.

For example, when the HCU collects the fault detection result about the incorrect connection of the charging gun, it can identify that the location information in the fault state is outside the vehicle, that is, the fault of the current charging gun belongs to the external fault of the vehicle, and at this time, a prompt message of "please connect the charging gun correctly" needs to be sent to the instrument of the vehicle by the HCU to prompt the driver to process the external fault of the vehicle as soon as possible. The driver can reconnect the charging gun according to the prompt information on the current instrument, if the connection is correct, the prompt information disappears, and when the charging condition is satisfied again, the charging function of the charging system can be timely recovered when the charging system fails.

It should be noted that the above-mentioned prompting method and the procedure and mode for recovering the charging function when the fault state is outside the vehicle are only illustrative, and are not particularly limited herein. The process and the method for dividing the internal faults and the external faults of the vehicle according to the fault detection result of the charging system and pertinently recovering the charging function are all within the protection scope of the embodiment of the invention.

Step S106, in response to the position information being that the fault state exists in the interior of the vehicle, determining the fault type of the fault state.

In the technical solution of step S106 of the present invention, the fault type may be used to indicate whether the fault generated by the charging system at this time is recoverable, and may include a recoverable fault and an unrecoverable fault. The unrecoverable faults may include at least a current driving cycle unrecoverable fault and a permanent unrecoverable fault, among others. The current drive cycle unrecoverable fault may be used to indicate that the fault is unrecoverable for one drive cycle from the controller of the vehicle to sleep.

In this embodiment, after determining whether the position information corresponding to the fault state is inside or outside the vehicle based on the fault detection result, it is possible to further determine, for the fault inside the vehicle, whether the fault type of the fault state at this time is a recoverable fault or an unrecoverable fault.

Alternatively, for a vehicle interior fault, the HCU may determine whether the fault in the current fault state is a recoverable fault or an unrecoverable fault. For an unrecoverable fault, it may be further determined whether the current driving cycle is unrecoverable or permanently unrecoverable at the time of the fault.

For example, when the HCU detects that the current fault is a fault affecting safety such as a collision or thermal runaway, it may be determined to be a permanent unrecoverable fault. For the permanent unrecoverable faults, the corresponding prompt information is required to be sent to prompt a driver to drive the vehicle to an automobile sales service (4S) store for maintenance, and the charging function can be recovered after the maintenance is completed by clearing the faults.

For another example, whether the current high-voltage circuit in the vehicle is in a fault state or not and what the specific fault is can be monitored in real time, if the current high-voltage circuit is detected to be an interlock fault or a high-voltage insulation fault by high-voltage interlock detection and insulation detection, the high-voltage insulation fault and the interlock fault can be determined to be unrecoverable faults in the current driving cycle in order to ensure the charging safety. For such faults, it may be determined whether the fault clears and the charging condition is met when the vehicle is again awakened. If the fault is cleared and the charging condition is met, the charging function can be immediately restored.

It should be noted that the above-mentioned faults corresponding to the permanently unrecoverable faults and the unrecoverable faults of the current driving cycle, and the process and method how to perform the recovery of the charging function under the corresponding conditions are merely illustrative, and are not limited herein. The process and method for dividing the unrecoverable fault into the unrecoverable fault and the permanent unrecoverable fault of the current driving cycle and recovering the charging function in a targeted manner are all within the protection scope of the embodiment of the invention.

In step S108, in response to the fault type being a recoverable fault, the charging system is controlled to perform a charging recovery operation.

In the solution of the above step S108 of the present invention, the charging function recovery operation may be used to recover the charging function of the charging system.

In this embodiment, after determining that the failure type of the failure state is a recoverable failure according to the existence of the failure state in the interior of the vehicle, the charging system may be controlled at this time to perform a charging recovery operation to cause the charging system to recover the charging function.

Optionally, the recoverable faults only include component faults, communication faults and Input/output (i/o) faults, wherein the component faults only need to be identified by each controller, and the reliability of fault recovery is ensured according to the fault mechanism and severity. Communication faults can be recovered according to network specifications and dormancy requirements or awakening. The IO type fault only comprises a sensor and an actuator related to a charging function, such as a charging port seat temperature sensor and the like.

Optionally, when the component type fault and the communication type fault are confirmed whether to be recoverable, the predetermined fault handling measures are maintained, and when the fault is confirmed to be recoverable, the charging system can be immediately controlled to execute the charging recovery operation to recover the charging function.

And when the low-voltage power supply is insufficient, the fault is cleared after the fault identification condition is not met. When the charging system fails, the HCU stops the charging function, the vehicle is dormant, the related controller controls the low-voltage main relay to be disconnected, and the fault recognition condition is not met at the moment to cause fault recovery, the HCU judges that the charging condition is met to continue to control the charging to start, and then the fault recognition condition is met to report the fault, so that the vehicle cannot be dormant although the charging function is forbidden, and the technical problem of controlling the fault recovery process of the charging system in the vehicle still exists.

However, in the embodiment of the invention, when the vehicle has external faults, high-voltage safety faults, sensor/actuator faults, key assembly faults and communication faults, the vehicle controller HCU carries out fault prompt, fault restorable judgment and a control method of function restoration, so that the reliability of fault restoration is considered, the control method of the function restoration process is considered, the dimension is more comprehensive, and the fault diagnosis and processing method is safer and more reliable. The control method for IO fault recovery is compatible with a controller which does not support low-voltage power supply recovery, and when a certain vehicle type needs the controller to conduct charging system IO fault identification, the original platform scheme can be directly used, development cost is greatly reduced, and therefore the technical problem that a charging system fault recovery process in a vehicle cannot be controlled is solved.

In the above steps S102 to S108, the state of the charging system in the vehicle may be detected in real time, and whether the charging system is faulty or not may be determined, and if the charging system is faulty, the fault detection results when the charging system is in the faulty state may be summarized. And the position information of the fault state at the moment can be determined according to the fault detection result, and if the current fault state is in the vehicle, the fault type of the fault in the fault state can be further judged to be a recoverable fault or an unrecoverable fault. If the fault is recoverable, the charging system can be controlled to execute corresponding charging recovery operation to recover the charging function of the charging system. The multi-dimensional consideration can be carried out on the recovery process of the charging function of the charging system, so that the fault diagnosis and the processing are more comprehensive, safer and more reliable, the purpose of recovering the charging function as soon as possible when the charging system breaks down is achieved, the technical problem that the recovery process of the charging system in the vehicle cannot be controlled is solved, and the technical effect of controlling the recovery process of the charging system in the vehicle is achieved.

The above-described method of this embodiment is further described below.

As an optional embodiment, step S104, after determining the location information corresponding to the fault state based on the fault detection result, the method further includes: responding to the position information to be in the exterior of the vehicle in a fault state, and controlling a vehicle controller in the vehicle to send first prompt information to a target object of the vehicle, wherein the first prompt information is used for prompting and adjusting components in a charging system; detecting the component in response to completion of the adjustment of the component to obtain a detection result; and responding to the detection result that the component has no fault and meets the charging condition, and controlling the charging system to recover the charging function.

In this embodiment, after determining the location information corresponding to the fault state according to the fault detection result, if it is determined that the location information is located outside the vehicle, the vehicle controller in the vehicle may be controlled to send first prompt information to the target object of the vehicle, and the target object is prompted by the first prompt information to readjust the component that is in the fault state. After the component adjustment is completed, the component may be inspected to determine if the component is malfunctioning and if the component meets the charging conditions at this time. If the detected detection result is that the component has no fault and meets the charging condition, the charging system can be controlled to immediately recover the charging function, wherein the first prompt information can be used for prompting the target object to adjust the component. The target object may be an occupant in the vehicle.

Optionally, each controller in the charging system identifies a related fault and sends a fault detection result corresponding to the fault state to the HCU through the CAN bus, and if it is determined that an unrecoverable fault occurs at this time, the fault state needs to be maintained all the time.

Optionally, for the external fault of the vehicle, the HCU may send a first prompt message to a graphical user interface in the vehicle, where the first prompt message may include what a component specifically generating a fault in the external fault of the vehicle is, how to solve the fault, and so on, and the target object may execute to process the fault state of the corresponding component according to the solution on the graphical user interface, where the graphical user interface may be used to perform information interaction with the target object, may be a device such as a vehicle navigation or an instrument in the vehicle, or may be an interface of corresponding software on a terminal device of the target object. It should be noted that the above graphical user interface is merely illustrative, and is not limited herein.

As an alternative embodiment, step S104, the fault existing outside the vehicle includes at least one of: the method comprises the steps of charging equipment failure, mismatching of a direct-current charging pile of a vehicle and the vehicle, overtime of communication of the direct-current charging pile and abnormal power supply of an alternating-current power supply of the vehicle.

In this embodiment, the presence of a fault with the exterior of the vehicle may include at least one of: the charging equipment fault, mismatching of the charged direct current charging pile and the vehicle, overtime communication of the direct current charging pile and abnormal power supply of the alternating current power supply of the vehicle can also comprise incorrect connection of the charging gun and abnormal power supply of the alternating current power supply. It should be noted that the above-mentioned external faults outside the vehicle are only examples, and are not particularly limited herein.

For example, if the external fault of the vehicle is that the charging gun is not connected correctly, the HCU may send a first prompt message "please connect correctly to the charging gun" to the meter to prompt the driver to connect correctly to the charging gun. And after the driver finishes corresponding operation according to the prompt of the first prompt information, if the fault is cleared and the charging condition is met, immediately recovering the charging function. If the external fault of the vehicle is a charging equipment fault, the HCU can send a first prompt message of 'the charging equipment fault, please replace' to the instrument to prompt a driver to replace the charging equipment. And after the driver finishes corresponding operation according to the prompt of the first prompt information, if the fault is cleared and the charging condition is met, immediately recovering the charging function.

For another example, if the external fault of the vehicle is that the dc charging pile is not matched with the vehicle, the HCU may send a first prompt message indicating that the dc charging pile is not matched with the vehicle and that the driver should replace the dc charging pile in time to the instrument. After the driver finishes the corresponding operation according to the prompt of the first prompt information, if the fault is cleared and the charging condition is met, the charging function is immediately restored. If the external fault of the vehicle is that the direct current charging pile is overtime in communication, the HCU can send a first prompt message of 'the direct current charging pile is overtime in communication and please reconnect the charging gun' to the instrument so as to prompt the driver to timely connect the charging gun. After the driver finishes the corresponding operation according to the prompt of the first prompt information, if the fault is cleared and the charging condition is met, the charging function can be immediately recovered.

As an alternative example, if the external fault of the vehicle is abnormal power supply of the ac power supply, the HCU may send a first prompt message of "abnormal power supply, please check the power supply and the charging cable" to prompt the driver to confirm the power supply and the charging cable in time. And when the driver finishes the corresponding operation according to the prompt of the first prompt information, if the fault is cleared and the charging condition is met, the charging function is immediately restored.

It should be noted that the content and the prompting manner of the first prompting information sent for different external faults are merely illustrative, and are not limited in particular herein.

As an alternative embodiment, step S106, in response to the location information being that the fault state exists in the interior of the vehicle, determines the fault type of the fault state, includes: and responding to the existence of the fault state in the vehicle, and controlling a whole vehicle controller in the vehicle to judge the fault state so as to obtain the fault type of the fault.

In this embodiment, if it is determined that the fault state exists in the vehicle, the vehicle controller in the vehicle may be controlled to determine the fault state and determine the fault type of the fault.

Alternatively, for an internal fault of the vehicle, it may be determined by the HCU whether the current fault is a recoverable fault or an unrecoverable fault.

Alternatively, if the HCU determines that the current fault is a component-type fault, a communication-type fault, or an IO-type fault, it may be determined as a recoverable fault.

Alternatively, if the current fault is judged to be a collision, thermal runaway, interlock fault, high voltage insulation fault, or the like by the HCU, it may be determined as an unrecoverable fault.

As an optional embodiment, step S106, after the vehicle controller in the vehicle is controlled to determine the fault state in response to the fault state existing in the vehicle, the method further includes: responding to the fault type as an unrecoverable fault, and controlling the whole vehicle controller to send second prompt information to a target object of the vehicle, wherein the second prompt information is used for carrying out fault alarm on the unrecoverable fault; the charging system is controlled to prohibit execution of the charge recovery operation within the target time range.

In this embodiment, after the fault type of the fault that will exist in the vehicle, if the fault type is an unrecoverable fault, the vehicle controller may be controlled to send a second prompt message to the target object of the vehicle to perform a fault alarm on the unrecoverable fault at this time, where the vehicle charging system may be controlled to prohibit the charging recovery operation from being performed within the target time range, where the second prompt message may be used to perform the fault alarm on the unrecoverable fault. The target time may be a time range set by the driver according to the requirement of the driver, or may be a time range preset in advance, which is only illustrated herein, and the setting mode and the range length of the target time range are not specifically limited.

Optionally, for unrecoverable faults, the charging function recovery may be disabled and the meter remains in fault alert, i.e., a second prompt similar to "the current charging system is in unrecoverable fault, unable to charge the function recovery, please handle in time" may be sent to the meter.

As an alternative embodiment, step S106, the unrecoverable faults include at least a first unrecoverable fault and a second unrecoverable fault, wherein the first unrecoverable fault is used to indicate that the fault condition is unrecoverable within the current driving cycle of the vehicle, and the second unrecoverable fault is used to indicate that the fault condition is unrecoverable within the driving cycle of the target number of vehicles.

In this embodiment, the unrecoverable faults may include at least a first unrecoverable fault and a second unrecoverable fault, wherein the first unrecoverable fault may be used to indicate that the fault condition is unrecoverable within the current driving cycle of the vehicle, which may be referred to as the current driving cycle unrecoverable fault. The second unrecoverable fault may be used to indicate that the fault condition is unrecoverable for a target number of driving cycles, which may be referred to as a permanent unrecoverable fault.

Optionally, the unrecoverable faults mainly include a current driving cycle unrecoverable fault and a permanent unrecoverable fault. Safety-affecting faults such as collisions and thermal runaway are defined as permanent unrecoverable faults. To ensure charging safety, high-voltage even faults and interlock faults may be defined as unrecoverable faults of the current driving cycle.

As an alternative embodiment, step S106, the method further includes: controlling the vehicle to travel to the target position in response to the fault type being a second unrecoverable fault to clear the second unrecoverable fault; controlling the vehicle to wake up again in response to the fault type being the first unrecoverable fault; and in response to successful re-wake, the fault of the charging system is cleared, and the charging condition is met, so that the charging system is controlled to restore the charging function.

In this embodiment, when the type of fault is a second unrecoverable fault, the vehicle may be controlled to travel to the target location to clear the second unrecoverable fault. When the fault type is the first unrecoverable fault, the vehicle can be controlled to wake up again, and if the vehicle is successfully waken up again, the fault of the charging system is cleared and the charging condition is met, the charging system can be controlled to resume the charging function.

Optionally, the recoverable failures include mainly component-type failures, communication-type failures, and IO-type failures. The fault of the component is mainly identified by each controller, and the reliability of fault recovery is ensured according to the fault mechanism and severity. And recovering the communication faults according to network specifications and dormancy/awakening requirements. And when the fault is confirmed to be recoverable, the charging function is immediately recovered.

Optionally, the IO-type fault mainly includes sensors and actuators related to the charging function, such as a charging dock temperature sensor, etc. The fault identification condition of the IO fault is that the low-voltage power supply of the controller is normal, namely the fault can be identified when the low-voltage power supply is normal, and the fault is cleared after the fault identification condition is not met when the low-voltage power supply is insufficient. Some controllers cannot recover the low-voltage power supply voltage, and the low-voltage power supply main relay is combined with an instruction to serve as a fault recognition condition. Therefore, a problem occurs that when the charging system fails, the HCU stops the charging function, the vehicle is dormant, the related controller controls the low-voltage main relay to be disconnected, the fault recognition condition is not met at the moment to cause fault recovery, the HCU judges that the charging condition is met to continuously control the charging to start, then the fault recognition condition is met to report the fault, and therefore the vehicle cannot be dormant although the charging function is forbidden. The invention provides a method which can effectively solve the problem, has no requirement on the implementation scheme of the related controller, and greatly reduces the development cost.

For example, if the fault at this time is an IO fault, an electronic control unit (Electronic Control Unit, abbreviated as ECU) of the vehicle may send the IO fault status to the HCU through a CAN bus or an internal variable, the HCU identifies a current fault status clearing condition, latches the fault if the current working condition is in the process of starting dormancy to complete dormancy, wakes up again, clears the fault and satisfies the charging condition, and the HCU controls the charging function to resume, if the process of starting dormancy to complete dormancy is not started, performs fault resumption confirmation, mainly in order to avoid high voltage danger caused by short-time resumption or erroneous resumption, and maintains a predetermined fault handling measure in the process. When the failure recovery is confirmed, a charge function recovery process control is performed, wherein the ECU may also be referred to as an xECU.

Example 2

The technical solution of the embodiment of the present invention will be illustrated in the following with reference to a preferred embodiment.

At present, along with the increasing severity of energy crisis and environmental pollution, the development of efficient, energy-saving and zero-emission pure electric vehicles has become a necessary trend of the development of the automobile industry. The working voltage of the charging circuit of the electric automobile is up to hundreds of volts, and when faults such as short circuit, circuit breaking and the like occur in the high-voltage circuit, the charging safety can be directly influenced. When the charging system has serious faults, the charging function is forbidden and the high voltage is reduced in order to ensure the safety of drivers and passengers. The charging function is an important guarantee for providing energy for the electric vehicle, and when the fault is confirmed to be completely recovered, the charging function is ensured as much as possible under the condition of meeting the safety, and the user can travel to a 4S shop for maintenance is also important.

In a related art, there is provided a vehicle including a power battery, a charging system thereof, and a control method of the charging system, the charging system including: the charging circuit comprises a quick charging interface and a quick charging contactor arranged between the quick charging interface and the power battery; a cut-off circuit for cutting off the charging circuit; and the controller is used for controlling the cut-off circuit to cut off the charging circuit when the quick charging contactor is adhered. The method mainly focuses on cutting off a quick charging loop of a vehicle when the quick charging contactor has adhesion faults, and only performing fault processing control on one fault and not referring to a control method during fault recovery, so that the technical problem that the process of fault recovery of a charging system in the vehicle cannot be controlled still exists.

In another related technology, an electric automobile power supply balancing fault recovery method with fixed capacity charge and discharge is provided, the technical problems that the balancing effect of the existing voltage balancing mode is affected by contact internal resistance, when the pressure difference is not large, the charge and discharge current is small, and the balancing time is long are solved, and the balancing fault recovery method is as follows: determining the charge and discharge cut-off voltage of each battery; setting a rated charge-discharge cut-off voltage difference value to obtain the charge-discharge capacity required by each battery; obtaining expected underfill capacity and residual discharge capacity of each battery through piecewise linear fitting of charge-discharge curves, and expected charge cut-off voltage and discharge cut-off voltage of each battery; and each battery is charged and discharged at a fixed capacity, so that the fault recovery of the power supply to be balanced is realized. The method mainly focuses on clearing the fault as soon as possible through control after the fault occurs, and is completely different from the range of the function recovery control method ensured from the whole vehicle level when the fault is recovered. Moreover, the method focuses on the balance fault of the power supply system, and is completely different from the range of the charging system of the embodiment of the invention. Therefore, there is still a technical problem that the process of the recovery of the charging system in the vehicle cannot be controlled.

However, the embodiment of the invention provides a fault recovery control method for an electric vehicle charging system, which can detect a state of the charging system in a vehicle in real time, judge whether the charging system is faulty, and collect a fault detection result when the charging system is in a fault state if the charging system is faulty. And the position information of the fault state at the moment can be determined according to the fault detection result, and if the current fault state is in the vehicle, the fault type of the fault in the fault state can be further judged to be a recoverable fault or an unrecoverable fault. If the fault is recoverable, the charging system can be controlled to execute corresponding charging recovery operation to recover the charging function of the charging system. The multi-dimensional consideration can be carried out on the recovery process of the charging function of the charging system, so that the fault diagnosis and the processing are more comprehensive, safer and more reliable, the purpose of recovering the charging function as soon as possible when the charging system breaks down is achieved, the technical problem that the recovery process of the charging system in the vehicle cannot be controlled is solved, and the technical effect of controlling the recovery process of the charging system in the vehicle is achieved.

The charging system can realize two charging modes of alternating current charging and direct current charging. When the main negative relay 5, the pre-charging relay 3 and the main positive relay 2 are sequentially closed according to a given strategy, the power battery 1 can be charged by the vehicle-mounted charger 8.

Step S303, judging whether the fault state is an internal fault.

In the technical solution provided in the above step S303 of the present invention, it is identified whether the current fault is a vehicle exterior fault or a vehicle interior fault. If the fault condition is an internal fault, step S306 may be performed. If the fault condition is an external fault, step S304 may be performed.

Optionally, the fault status of each critical component of the charging system is collected by the HCU, identifying whether the current fault is a vehicle external fault or a vehicle internal fault.

Optionally, the vehicle external fault mainly includes: the charging gun is not connected correctly, the charging equipment fails, the direct current charging pile is not matched with the vehicle, the direct current charging pile is overtime in communication, the alternating current power supply is abnormal in power supply, and the like. When the HCU recognizes the above-mentioned fault, the user is prompted by the meter to "please connect correctly the charging gun", "the charging device is faulty, please replace", "the direct current charging pile is not matched with the vehicle", "the direct current charging pile is replaced", "the direct current charging pile is overtime in communication", "the charging gun is reconnected", "the power supply is abnormal", and the power supply and the charging cable are checked.

And after the driver finishes the corresponding operation according to the prompt, if the fault is cleared and the charging condition is met, the charging function is immediately restored.

For another example, if the external fault of the vehicle is that the dc charging pile is not matched with the vehicle, the HCU may send a prompt to the instrument that the dc charging pile is not matched with the vehicle and the driver is required to replace the dc charging pile in time. And after the driver finishes the corresponding operation according to the prompt, if the fault is cleared and the charging condition is met, the charging function is immediately restored. If the external fault of the vehicle is that the direct current charging pile is overtime in communication, the HCU can send a prompt of 'the overtime in direct current charging pile communication and please connect the charging gun again' to the instrument so as to prompt a driver to connect the charging gun in time. After the driver finishes the corresponding operation according to the prompt, if the fault is cleared and the charging condition is met, the charging function can be immediately restored. If the external fault of the vehicle is abnormal power supply of the alternating current power supply, the HCU can send a prompt of 'abnormal power supply, please check the power supply and the charging cable' to prompt a driver to confirm the power supply and the charging cable in time. And when the driver finishes the corresponding operation according to the prompt, if the fault is cleared and the charging condition is met, the charging function is immediately restored.

In the technical solution provided in the above step S307 of the present invention, for the unrecoverable fault, the recovery of the charging function may be prohibited, and the meter may keep the fault alarm, that is, may send the fault alarm information similar to "the unrecoverable fault occurs in the current charging system, the recovery of the charging function is impossible, and the timely processing is requested".

In step S308, the failure may resume validation.

In the technical solution provided in the above step S308 of the present invention, it may be determined whether the fault is recoverable.
