New energy vehicle connectors in the vehicle system?

I. The application of new energy vehicle connectors in vehicle system? New energy vehicle connectors are one of the main categories of connectors. In recent years, with the development of China's new energy vehicles, it is gradually detached from the traditional high-voltage high-current connectors and traditional low-voltage connectors. Compared with the traditional high-voltage high-current connectors, the working conditions of new energy automobile connectors are more complex and changeable, and the reliability of the connector is required to be higher. Compared with the traditional low-voltage automotive connectors, the reliability of new energy vehicle connectors is increased due to the increase in voltage level (the current and voltage of the mainstream system is higher than 300V DC), which increases the risk of electric shock to the human body; therefore, compared with the traditional low-voltage plug-ins, the insulation and protection requirements of this product have been improved. The role of new energy vehicle connectors is mainly to ensure that the car's high-voltage interconnection system, that is, to build a bridge where the internal circuit is blocked or isolated, so that the current can flow. The composition of the new energy vehicle connector can usually be divided into three parts: auxiliary structure, such as shell and sealing part, insulation part and conductive contact pair. Through the plug sleeve and socket sleeve fit and mutual collaboration, to achieve the function of connection and conductivity. The high voltage connector is mainly used for high voltage and high current circuits in new energy vehicles, acting simultaneously with conductive cables. It transmits the energy from the battery pack through different circuits to various parts of the vehicle system, such as the battery pack, motor controller, and DCDC body power supply unit (e.g., converter, charger).
