We all know about new energy electric vehicles in our daily life. In electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, and air conditioning power. Automobile harness is the main body of automobile circuit network and the carrier of automobile circuit.



Automobile harness is the bridge and link of vehicle electrical components and the nervous system of vehicle power and signal transmission and distribution. The high-voltage harness can be configured according to different voltage levels, and the internal and external harnesses of electric vehicles can be connected. It mainly applies the signal distribution of the internal harness of the distribution box to transmit electric energy with high efficiency and quality and shield external signal interference. The high-voltage connection system consists of high-voltage harness and connector. DC / DC, water heating PTC charger, air heater, DC charging port, power motor, high-voltage harness, maintenance switch, inverter, power battery, high-voltage box, power air conditioner, AC charging port, etc. all need connectors; High voltage harness is the neural network of high voltage system of new energy vehicles, which is very important.



It also mainly includes battery system, powertrain, high-voltage electric control system, charging system, high-voltage equipment and its harness system. The high-voltage line of electric vehicle is used to connect the charging port with the battery, the interior of the battery, the battery with the engine and other components, as well as the field of 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, poor driving environment, salt fog and electromagnetic field, oil and chemicals, low smoke halogen-free flame retardant and other environmental and safety requirements. Application characteristics of electric vehicle cable: small wiring space, high current and high voltage, and all indicators meet the requirements of environmental protection and safety.
