Requirements of connecting cables for key components of new energy vehicles

China [CN]

Compared with traditional cars, new energy vehicles have a greater increase in the number of electric drive units and electrical equipment. The internal power current and information current are intricate, especially the high-current, high-voltage electric drive system, which has a great impact on the reliability of the connector. New energy vehicles have put forward higher requirements for sex, volume and electrical performance, so the demand and quality requirements for connector products in new energy vehicles will increase significantly.

New energy vehicles use large-capacity lithium batteries, and their operating voltage range jumps from 14V in traditional vehicles to 400~600V. Therefore, comprehensive improvements in the automotive electronic and electrical architecture are required, and connectors, as key components, bear the brunt.

According to practical data, limited by the current level of technology, the continuous driving range of pure electric vehicles is very limited, and quickly replaceable batteries can make up for this shortcoming. The quick-swap battery connector for electric passenger cars is an important component of the quick-swap battery system. It is a special connector used to achieve quick electrical connection and separation between the entire vehicle and the quick-swap battery system. It is also essentially a high-voltage connector. .
