Power Battery Applications for High Voltage Cables

High voltage cables for new energy vehicles are a key component of connecting electric vehicle batteries and electric drive systems. It undertakes the important task of transmitting high voltage and high current from the battery to the electric drive system. Due to its special working environment and electrical characteristics, high-voltage cables for new energy vehicles have strict requirements in design and manufacturing.

The electric vehicle high voltage cable is used to connect the charging port to the battery, inside the battery, between the battery and the engine and other components, as well as battery energy storage equipment and other areas, as a carrier of power transmission.

This section describes the general standards for high-voltage cables.

For example, the standards used in China are:

GB/T 25085 (ISO6722): Dimensions, test methods and requirements for 60V and 600V single-core cables for road vehicles

GB/T 12528: Cable for rail vehicles with rated AC voltage of 3kV and below

QC/T 1037: High voltage cable for road vehicles

Soft product, bending radius up to 5D; High and low temperature resistance, oil resistance, acid and alkali resistance, water resistance, wear resistance, cracking resistance, ultraviolet resistance; Good flame retardant performance; Good conductivity, small conductor temperature rise; All materials comply with RoHS 2.0 environmental standards.
