Structure and standards of high-voltage connectors for new energy vehicles

Structure and standards of high-voltage connectors for new energy vehicles

1. Composed of high-voltage connectors

Basically, it consists of: shell (male end), female end), terminal (male female terminal), shielding cover, sealing (tail, half end, line end, contact) tail protection cover, high-voltage interlocking system, CPA system, and other structures

2. High voltage connector standards

At present, high-voltage connectors are based on industry standards; From a standard perspective, there are safety regulations There are also testing standards for performance and other requirements. Currently, the most mainstream design of connector manufacturers will basically refer to the industry standard LV series standards jointly developed by the four major European original equipment manufacturers: Audi, BMW, Daimler, and Porsche; In North America, it mainly comes from oneself; We do not draft standards related to SAEuscar, but we often use standards such as uscar 2.37, which are mainly from the joint wiring harness connection organization EWCAP of Chrysler, Ford, and General Motors in the United States. It was previously mentioned in the connection forum that this organization was established in 1994. In 2008, in order to adapt to an increasing number of issues, the HEV organization updated its requirements for SAE-USCAR2 Upgrade the voltage level from the original 20V to the 600V we see now;

For Europe, it is basically the VWBMWDaimler, jointly developed by original equipment manufacturers in Germany as the car owner, which also plays a very important role in the formulation and promotion of standards. The interests in VW related industry standards have also been reflected, and the AK working group has even refined the requirements for installation interface dimensions, which basically conforms to the consistent style of European and American host manufacturers. TEAmphenolKostalmolexdelphi has added all of these standards;
