Voltage Detection and Troubleshooting
The power source of the pure electric vehicle is the power battery, and the voltage of the power battery has a great relationship with its discharge capacity and discharge efficiency. When the power battery voltage is at a low voltage, it is still discharged with a large current, which will damage the high-voltage electrical equipment and seriously affect the service life of the battery. When it is detected that the voltage is too high or too low, the relevant circuit should be cut off in time. Therefore, in order to ensure the safety of electric appliances, power batteries and drivers and passengers of pure electric vehicles when the power battery is low, it is necessary to design a voltage detection circuit to perform real-time and accurate detection of the working voltage of the high-voltage circuit system and safe and reasonable fault handling.
