A brief discussion on the high-voltage cable between the battery and the motor of new energy vehicles

China [CN]

In the "body" of electric vehicles, the high-voltage cable connecting the battery and the motor can be called the "power blood vessel" and is extremely important. ​

From a functional point of view, the automotive cable carries the connection between the battery and the motor and needs to provide efficient power transmission.

In terms of structural characteristics, the design of high-voltage cables is very particular. The conductor part generally uses materials with excellent conductivity such as copper or aluminum alloy, and the insulation layer uses high-strength plastic or rubber to put on a solid "protective clothing" for the conductor to prevent dangerous situations such as leakage and short circuit. After all, the high-voltage system of electric vehicles, safety is the top priority.

In terms of daily maintenance, regular inspection of high-voltage cables is essential. Especially after long-distance driving or use in bad weather conditions, it is necessary to check carefully. Keep the cable and its connections clean to avoid dust and moisture intrusion, monitor the battery status at the same time, and let the battery work under reasonable charging and discharging conditions. These will help to extend the service life of high-voltage cables and ensure the stable and safe operation of electric vehicles.
