Interpretation of linear performance of electric vehicle high voltage cable

China [CN]

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

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

Structural differences of three kinds of high voltage cables: XLPE, XLPE + tinned copper braid+ Aluminum foil + shell: XLPE, bare copper insulation: XLPE, outer skin: XLPE

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

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

Double layer electric vehicle high voltage line: mainly used in occasions with serious vibration environment, such as the connection between battery and high voltage.
