In the drive mode of the updated relay, the electrically-driven control module BMS is arranged in a high-side drive loop of the relay, the whole vehicle control module VCU is arranged in a low-side drive loop of the relay, or the whole vehicle control module VCU is arranged in the high-side drive loop of the relay, and the electrically-driven control module BMS is arranged in the low-side drive loop of the relay. That is, when the BMS fails and cannot stop charging, the VCU monitoring loop may shut down the corresponding low-side or high-side loop, thereby achieving a redundant design.
Therefore, the safety performance of the relay in the charging process of the new energy automobile is improved, and the risk of overcharge and explosion of the battery pack is greatly reduced. And while the safety performance of the relay is improved, the scheme of the invention has less change on the wire harness of the battery pack, only one wire harness is added, and only one driving channel of the VCU is occupied, so that the change cost is low.
The electric drive control module BMS comprises a voltage value acquisition unit and a first judgment unit, wherein the voltage value acquisition unit is used for acquiring a main loop voltage value, the first judgment unit is used for judging whether the acquired main loop voltage value is greater than the maximum charging upper limit voltage of the battery pack, if so, the electric drive control module BMS judges that the charging fault occurs, and cuts off the relay so as to stop charging.

The system further comprises a fault reporting module for reporting fault information of the electrically-driven control module BMS to the whole vehicle control module VCU, the real-time acquisition unit is further used for acquiring the fault information reported by the fault reporting module, the whole vehicle control module VCU further comprises a second judgment unit, when the electrically-driven control module BMS breaks down, the second judgment unit judges whether any main loop voltage value exists in all main loop voltage values acquired by the real-time acquisition unit and is larger than the maximum charging upper limit voltage of the battery pack, if yes, the overcharge fault is judged to occur, and the whole vehicle control module VCU cuts off a relay to stop charging.
That is, only when the electrically driven control module BMS malfunctions, the complete vehicle control module VCU performs the judgment of whether the overcharge malfunction occurs and the operation of the cut-off relay. Therefore, the working efficiency of the whole system is improved, and resource waste is avoided.
The relay can be a quick-charging relay or a slow-charging relay, namely the system can be applied to a quick-charging mode of the battery pack and can also be applied to a slow-charging mode of the battery pack. And the relay is a normally closed relay.

and S4, the second judgment unit judges whether the battery pack has an overcharge fault, if so, the VCU of the whole vehicle control module cuts off the relay to stop charging and finish, and if not, the step S1 is returned.
Specifically, the method comprises the following steps:
