Interpretation of wire properties of automotive high-voltage cables

China [CN]

The high-voltage line of the electric vehicle is used to connect the charging interface with the battery, the battery interior, the battery and the engine and other components, as the carrier of power transmission. Due to the harsh application environment of automobiles, the high-voltage wire materials of electric vehicles play a very important role and require very high performance of materials. This is one of the keys to the high-voltage line of electric vehicles.

Classification of high-voltage wires for electric vehicles: the core component of new energy electric vehicles is the battery. The first high-voltage line used for battery connection of electric vehicles is an ordinary single-layer high-voltage line; While the motor connection needs to prevent signal interference, OMG adds a shielded single-layer high-voltage line to the shielding layer; Due to the harsh application environment of electric vehicles, OMG has developed double-layer high-voltage lines with better temperature resistance, wear resistance and protection on the basis of single-layer high-voltage lines. Therefore, we divide the commonly used high-voltage lines of electric vehicles into three categories: single-layer high-voltage lines of electric vehicles, single-layer shielded high-voltage lines of electric vehicles, and double-layer high-voltage lines of electric vehicles.

The structural difference of three types of high-voltage cables: XLPE, XLPE+tinned copper braid. Aluminum foil+shell: XLPE, bare copper insulation: XLPE skin: XLPE

Single layer electric vehicle high-voltage line: mainly used for connection between equipment without shielding requirements, such as connection between livestock batteries.

Single layer shielded electric vehicle high-voltage line; It is mainly used for connection between equipment with shielding requirements, such as connection between motor and frequency converter.

High voltage line of double deck electric vehicle: mainly used for occasions with severe vibration environment, such as connection of battery and high voltage.
