Requirements for connecting cables for key automotive components

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 affects the reliability of the connector. , volume and electrical performance have put forward higher requirements, 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 Yilanzhong Consulting data, China's new energy vehicle high-voltage connector market size was 3.95 billion yuan in 2018. It is expected that the domestic electric vehicle high-voltage connector market size will reach 8.58 billion yuan by 2023, with an average annual compound growth rate from 2018 to 2023 The rate reached 16.78%, which is higher than the average compound growth rate of automotive connectors.)

Due to the current technological level, 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. .
