Evolution of ISO High Voltage Copper Standards

China [CN]

In electric/hybrid vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. It mainly includes the battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment, and its wiring harness system. The electric vehicle high-voltage wire 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 for power transmission. Due to the harsh application environment in the vehicle, electric vehicle high-voltage cables have very high performance requirements.

Electric vehicle cable application characteristics: due to the car wiring space is small, high current and high voltage, high and low temperature environment more heat dissipation is not good, the car driving environment is harsh; cable needs to have salt spray and electromagnetic fields, oil and chemicals, with low smoke and halogen-free flame retardant and other environmental and safety requirements.

Common specifications: 2.5mm²--70mm²and other

Characteristics: thermosetting material, high and low temperature resistance, soft, acid and alkali resistance, shielding structure, tear resistance, smooth, bending radius up to 5D; oil, water, wear resistance, UV resistance; good flame retardancy; good electrical conductivity, all materials comply with RoHS 2.0 environmental standards.
