Vehicle energy management and optimization In pure electric vehicles, the power battery not only supplies power to the drive motor, but also supplies power to electric accessories. Therefore, in order to obtain the maximum driving range, the vehicle controller will be responsible for the energy management of the vehicle. To improve energy utilization. When the SOC value of the battery is relatively low, the vehicle controller will issue instructions to certain electric accessories to limit the output power of the electric accessories to increase the driving range.
Monitoring and display of vehicle status The vehicle controller obtains real-time data of vehicle operation by directly collecting signals and receiving data on the CAN bus, including speed, working mode of the motor, torque, speed, remaining power of the battery, total Voltage, cell voltage, battery temperature and fault information, and then send these real-time information to the on-board information display system through the CAN bus for display. In addition, the vehicle controller regularly detects the communication of each module on the CAN bus. If a node on the bus is found to be unable to communicate normally, the fault information will be displayed on the vehicle information display system, and reasonable measures will be taken to deal with the corresponding emergency. Processing to prevent the occurrence of extreme conditions, so that the driver can directly and accurately obtain the current operating status information of the vehicle.
