Current Detection and Troubleshooting
Due to the influence of the running road environment and the driver’s control, the running state of the car will change at any time, and the discharge current of the power battery will change significantly with the driver’s control. When the current exceeds the preset allowable range, it will cause the temperature to rise excessively, which will not only affect the life of the battery, but also cause abnormal reactions in extreme cases, causing damage to the automotive power devices and endangering the safety of the automotive high-voltage system. Therefore, this requires the high-voltage management system to monitor the current of the power battery in real time. When abnormal current is detected, the high-voltage management system will cut off all high-voltage circuits in time and issue an audible and visual alarm to remind drivers and other cars.
