Detailed Explanation of High Voltage Interlock (HVIL) Function for New Energy High Voltage Connectors 1

New energy high-voltage connector is an electrical connector used to connect the battery pack and power system of electric or hybrid vehicles. It has the characteristics of high voltage and high current, and requires protection with high voltage interlock (HVIL) function.diode

High Voltage Interlock (HVIL) is a safety protection function used to prevent electric shock from high voltage power sources when the connector is not connected or disconnected. It disconnects the electrical connection between the battery pack and the power system to ensure that there is no high-voltage current passing through the human body during maintenance, repair, battery replacement, or other operations that may cause harm.diode

The implementation of high voltage interlock (HVIL) function usually includes the following aspects:

1. Electrical disconnection: The high voltage interlock (HVIL) function is achieved by disconnecting the electrical connection between the battery pack and the power system. When the connector between the battery pack and the power system is not connected or poorly connected, the high voltage interlock (HVIL) function will automatically disconnect the electrical connection to avoid the generation of high voltage current.diode
