EV High-Voltage Cable introduction:

On electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. It mainly includes battery system, powertrain, high-voltage electronic control system, charging system, high-voltage equipment, and its wiring harness system. Electric vehicle high-voltage lines are used to connect the charging port and the battery, the interior of the battery, the battery and the engine and other components, as well as battery energy storage equipment and other fields, as the carrier of power transmission. Due to the harsh application environment in the vehicle, electric vehicle high-voltage cables have very high performance requirements. Application characteristics of cables for electric vehicles: small wiring space, high current and high voltage, high and low temperature environment, poor heat dissipation, bad driving environment with salt spray and electromagnetic field, oil pollution and chemicals, low smoke halogen-free flame retardant,
