Description

Power transmission between the power battery and high-voltage components

The most common scenario is connecting the power battery pack and high-voltage components such as the high-voltage distribution unit (PDU), drive motor, on-board charger (OBC), and air conditioning compressor, which are responsible for transmitting high-voltage DC power (usually 300V-800V) to power the vehicle's power system or high-voltage accessories.

Integrated high-voltage interlock (HVIL) safety circuit

The small black plug shown in the picture is the high-voltage interlock signal terminal, which is the "safety sentinel" of the high-voltage system. It can monitor the connection status of the high-voltage connector in real time. Once the plug is loose or not properly inserted, it will trigger the vehicle controller to cut off the high-voltage power to avoid the risk of leakage and arcing.
