New energy vehicles are now hot, and various devices and products related to them are developing rapidly along with new energy vehicles. Automotive systems have always been the main application market for connectors, and connectors are widely used in various systems such as automotive power systems, body systems, and in-vehicle equipment systems. Whether in hybrid or pure electric vehicles, there is a complete set of high-voltage connection systems. It can be said that it is new energy vehicles that promote the development of high-voltage connections.
When the high-voltage system of the new energy vehicle is working, the discharge current reaches tens of amperes, or even as high as hundreds of amperes. Once the high-voltage connector has a problem, it will be overheated in light, and high temperature or combustion accident will occur in severe cases. As the domestic electrical connection is put on the national standard schedule as an important content, the “Technical Requirements for High Voltage and High Current Wiring Harness and Connectors for Electric Vehicles” has achieved a relatively closed loop for the electrical connection part.
