[0047] In the embodiment of the present application, while recording the fault process code, the fault process code is associated with the corresponding charging fault.

[0048] Optionally, during the initial charging startup phase, a charging fault in the vehicle charging system is detected, and a corresponding fault process code is recorded for at least one detected charging fault, including: performing a self-check on the vehicle charging system to determine whether a system fault occurs in the vehicle charging system, and when it is determined that a system fault occurs in the vehicle charging system, recording a corresponding fault process code (for example, fault process code 01).

[0049] Perform a self-inspection on the vehicle charging system, including checking the connection status of each device in the vehicle charging system, the insulation performance of the vehicle charging system, etc., to determine whether it meets the preset safety requirements and the safety requirements of national standards. If it meets the preset safety requirements or the safety requirements of national standards, it is considered that no system failure has occurred. If it does not meet the preset safety requirements and the safety requirements of national standards, it is considered that a system failure has occurred.

[0050] Optionally, during the initial charging startup phase, a charging fault in the vehicle charging system is detected, and a corresponding fault process code is recorded for at least one detected charging fault. The method also includes: when it is determined that there is no system fault in the vehicle charging system, detecting a first resistor of a charging gun connected to the vehicle to determine whether the first resistor meets a preset resistance condition; when it is determined that the first resistor does not meet the preset resistance condition, recording a corresponding fault process code (for example, fault process code 02).

[0053] Figure 2 A schematic diagram of an existing charging control steering circuit is shown.

[0054] Optionally, the first charging signal may be Figure 2 The CP signal shown, when detecting the first charging signal, can detect whether the duty cycle of the PWM wave of the CP signal meets the first signal condition; the first signal condition can be set according to actual needs. In an example, the first signal condition can be set to that the duty cycle of the PWM wave of the CP signal satisfies 3%≤D≤7%||8%≤D≤90%, wherein || represents logical "or" and D represents the duty cycle.

[0055] Optionally, in the initial charging startup phase, a charging fault of the vehicle charging system is detected, and a corresponding fault process code is recorded for at least one charging fault detected, further comprising:

[0056] When it is determined that the first charging signal satisfies the first signal condition, the state of the electronic lock of the charging seat in the vehicle is detected to determine whether the electronic lock is in a locked state after a first time period after receiving the locking command; when it is determined that the electronic lock is not in a locked state after the first time period after receiving the locking command, the corresponding fault process code is recorded.

[0057] The first time period can be set according to actual needs.

[0058] If the electronic lock is still not locked after the first time period of receiving the lock command, it is considered that the electronic lock is not locked when it should be locked, that is, a fault occurs, and a corresponding fault process code (eg, fault process code 04) is recorded.

[0059] Optionally, in the initial charging startup phase, a charging fault of the vehicle charging system is detected, and a corresponding fault process code is recorded for at least one charging fault detected, further comprising:

[0061] The first charging switch may be Figure 2 The S2 switch shown can be Figure 2 The detection point 1 in is used to detect whether the S2 switch is closed; the second time period can be set according to actual needs.

[0062] If the first charging switch is still not closed after receiving the second time period of the closing instruction, it is considered that the first charging switch is not closed when it should be closed, that is, a fault occurs, and a corresponding fault process code (eg, fault process code 05) is recorded.

[0065] The first designated voltage may be set according to actual needs or existing national standards, for example, may be set to 220V (volts).

[0066] In such Figure 2 In the example shown, after the S2 switch is closed, the power supply equipment (such as a charging pile) will close the K1 switch and the K2 switch to release a 220V AC signal. Under normal circumstances, the vehicle charging system will receive the 220V AC signal. If the vehicle charging system does not receive the 220V AC signal, it is considered that a circuit of the vehicle charging system has failed, and the corresponding fault process code (for example, fault process code 06) is recorded.
