Shanghai Automotive Group Co., Ltd. has applied for a patent related to a vehicle control method for instances when the battery management system resets. This patent aims to ensure that the vehicle’s high voltage system can restore power output effectively. The application, titled “Vehicle Control Method and Related Devices for Battery Management System Reset,” has a publication number of CN119898195A and was filed in October 2023.
The patent summary indicates that the proposed method allows the battery management system to obtain a flag signal from the controller to determine if a reset has occurred. When a reset is confirmed, the battery management system sends a first signal to the vehicle control unit. Upon receiving this signal, the vehicle control unit requests the closure of the main relay from the battery management system. Based on this request, the battery management system will close the main relay, enabling the vehicle’s high voltage system to power on and maintain the vehicle’s power output.
This method ensures that after a reset of the battery management system, the main relay can be automatically controlled to close, allowing the vehicle to power back on without the user noticing any loss of function due to the reset. This improvement enhances the overall driving experience and increases safety while driving.
According to information from Tianyancha, Shanghai Automotive Group Co., Ltd. was established in 1984 and is based in Shanghai.
