What is power battery wiring harness? What are the types of power battery harnesses and who are the manufacturers?

Power battery wiring harness is a wiring harness system used for electrical connection and signal transmission of the power battery system of electric or hybrid vehicles. It consists of multiple wires and connectors for connecting key components such as battery modules, battery management systems, motor controllers, and so on. Power battery wiring harnesses have high current transmission, durability and safety requirements in high temperature environments. Depending on the electric vehicle model and manufacturer, the type and configuration of the power battery wiring harness may vary. Generally speaking, power battery harnesses can be divided into the following categories: High-voltage battery harness: Used to transmit high-voltage DC power, connecting power and signal wires between battery modules as well as with battery management systems and motor controllers. Sensor harness: used to connect various sensors such as temperature sensors, voltage sensors, current sensors, etc. to monitor the status and parameters of the power battery system. Control harness: used to connect the motor controller and other control modules, transmit control signals and feedback signals, and realize the motor's start, stop, speed regulation and other functions. Charging harness: used to connect the electric vehicle charging interface and battery system, transmit charging power and communication signals, and realize battery charging and charging status monitoring. Management Harness: Used to connect the battery management system (BMS) and other management modules, transmit battery status information, fault diagnosis information and safety protection signals. Manufacturers of power battery wiring harnesses include many automotive parts suppliers and electrical system integrators. The following are some of the manufacturers of power battery wiring harnesses: Sumitomo Electric Industries: As one of the world's leading wire and cable manufacturers, Sumitomo Electric provides high-quality power battery wiring harness solutions.Yazaki Corporation: As an automotive electrical system supplier, Yazaki provides a wide range of power battery wiring harness solutions.
