What is the profile of new energy vehicle connectors?

I. How is the introduction of new energy vehicle connectors? There are many types of new energy vehicle connectors, such as energy storage connectors, high-voltage interlocking connectors, charging guns, etc., which are more or less common; as new energy vehicles are "green" vehicles, connectors are also required to be green and environmentally friendly, of which the first thing is the safety issue, because the range of the operating voltage of 400V ~ 600V, the operating current range of 50A ~ 300A or even higher. 600V, the operating current range of 50A ~ 300A or even higher, taking into account the operator in the car's entire life cycle will inevitably come into contact with the engine compartment, a high standard of protection against electric shock demand is obvious, in addition, in such a high power, electromagnetic interference is another important issue, as well as the connector insertion and removal operations will produce arc, which will seriously harm the electrical connection and electronic equipment, and may cause the car to burn. Electronic equipment, and may cause automobile combustion, all of which require special design and development of the connector. New energy vehicle connectors to achieve its high-performance requirements mainly rely on strict design specifications, such as in the case of exposure to prevent high-voltage air breakdown, which requires the retention of a certain air gap in the case of high voltage and high current. Its temperature rise can not exceed the rated value, in the selection of shell materials to consider the weight, strength and whether it is easy to process, and how to maintain the stability of the material properties of the connector terminals at different temperatures, how to ensure that the necessary conductivity, etc. need to be considered.
