What are the accessories for new energy vehicles?

What are the accessories for new energy vehicles? New energy vehicle parts cover power, electrical, chassis, body, safety, comfort and intelligent systems, etc. All systems work together to ensure vehicle performance, safety and user experience. The following are specific classifications and descriptions:

1. Power battery and management system: As the ‘energy heart’ of new energy vehicles, power battery is the key to power source. Its cost accounts for about 50% of the whole vehicle, and the types cover lithium-ion batteries, nickel-metal hydride batteries and emerging sodium-ion batteries. Battery Management System (BMS) monitors the battery status in real time to ensure safe and efficient charging and discharging, and prevent potential risks such as over-charging and over-discharging.

2. Drive motors and controllers: Drive motors convert electrical energy into mechanical energy, which is the power source of vehicle driving. Common types include permanent magnet synchronous motors and asynchronous motors, each with its own characteristics of high efficiency and reliability.

3. High-voltage distribution box: as a ‘power hub’, it reasonably distributes high-voltage electricity to the motor, air-conditioning compressor and other components to ensure the stability and safety of power supply.

4. Braking system: including vacuum booster, electronic brake control system, etc., which provides reliable braking force and guarantees driving safety.

5. Suspension system: composed of shock absorbers, springs, stabiliser bars, etc., absorbing road vibrations and enhancing driving stability and comfort.

6. Body structure parts: doors, windows, roof, etc. constitute the basic framework of the vehicle to ensure safety and sealing.

7. Active safety equipment: anti-lock braking system (ABS), electronic stability programme (ESP), etc. to prevent accidents and improve driving safety.

8. Air conditioning system: Cooling/heating equipment and air circulation system regulate the temperature and humidity inside the vehicle to enhance comfort.
