Overview of high-voltage connectors

Publish Time: 2025-04-29

High-voltage connectors, also known as high-voltage connectors, are a type of automotive connector. They generally refer to connectors with an operating voltage of more than 60V and are mainly responsible for transmitting high currents.

High-voltage connectors are mainly used in high-voltage and high-current circuits of electric vehicles. They work together with wires to transmit the energy of the battery pack through different electrical circuits to various components in the vehicle system, such as battery packs, motor controllers, DCDC converters, chargers and other high-voltage components.

At present, there are three main standard systems for high-voltage connectors, namely LV standard plug-ins, USCAR standard plug-ins, and Japanese standard plug-ins. Among these three plug-ins, LV currently has the largest circulation in the domestic market and the most complete process standards.
