Composition of power distribution system for new energy vehicles

Jan 01,2025

The composition of the power distribution system for new energy vehicles mainly includes the following aspects:

1. Battery pack: The battery pack is the core part of the power distribution system for new energy vehicles, consisting of dozens or even hundreds of battery cells arranged in series or parallel to provide power to the vehicle. The battery pack has a huge energy reserve, ensuring that the car can last for a long time.

2. Electric motor controller: The electric motor controller is another key component of the electrical system of new energy vehicles, mainly responsible for controlling the speed and torque of the electric motor, ensuring the normal driving and power output of the vehicle. The motor controller consists of an electronic control unit (ECU), power electronic devices, sensors, and actuators, among which the electronic control unit is the core of the entire control system. By collecting and processing sensor signals, precise control of the motor is achieved.

3. Auxiliary electrical system: The auxiliary electrical system includes various electronic devices and sensors, which are used to provide power supply and monitoring functions for various parts of the vehicle. The system consists of a power management module, lighting system, air conditioning system, in car entertainment and navigation system, etc. These devices obtain the required electrical energy through the in car battery or directly connected to the battery pack. The main function of the auxiliary electrical system is to provide lighting, ventilation, air conditioning, and entertainment functions for the vehicle, and to monitor and provide feedback on the vehicle's status through various sensors to ensure its safety and performance.

The distribution system of new energy vehicles may also include related components of high-voltage electrical systems, such as DC/DC voltage converters, charging devices, high-voltage wiring harnesses, and safety protection systems. These components together form a complex and efficient power distribution system for new energy vehicles, ensuring the normal operation and power output of the vehicle.
