The Application and Test Standard of Optocoupler in EV

On 2022-Dec-Fri

The function of auto optocoupler is mainly to realize optocoupler isolation. In electric vehicles, there are usually high voltage circuits and low voltage circuits. The high-voltage battery and its connected equipment in the vehicle are a floating load system, which are completely electrically isolated from the chassis and low-voltage system. In order to prevent mutual interference between low and high voltage systems, and to collect leakage to the chassis, optocouplers. Although optocouplers are small, they are essential.
