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