New energy vehicles consist of three parts: electric drive system, power supply system, and auxiliary system. The electric drive system includes electronic controllers, power converters, electric motors, mechanical transmission devices, and wheels. The power system includes a power supply, an energy management system, and a charger. The auxiliary system includes auxiliary power source, power steering system, navigation system, air conditioner, lighting and defrosting device, wiper and radio, etc.
New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels and adopt new on-board power devices), integrate advanced technologies in vehicle power control and drive, and form advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.
According to the size of the scope, new energy vehicles can be divided into broad and narrow new energy vehicles.
Generalized new energy vehicles, also known as alternative fuel vehicles, include pure electric vehicles, fuel cell electric vehicles, and other vehicles that all use non petroleum fuels, as well as hybrid electric vehicles, ethanol gasoline vehicles, and other vehicles that partially use non petroleum fuels. All existing new energy vehicles are included in this concept, specifically divided into six categories: hybrid vehicles, pure electric vehicles, fuel cell vehicles, alcohol ether fuel vehicles, natural gas vehicles, etc.
Narrowly defined new energy vehicles can refer to the provisions of the national "Management Rules for the Access of New Energy Vehicle Production Enterprises and Products": New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and driving, and form vehicles with new technologies, new structures, and advanced technical principles.
New energy vehicle accessories mainly include the following parts:
1. Electric drive system: This is the core component of new energy vehicles, including electronic controllers, power converters, electric motors, mechanical transmission devices, and wheels.
2. Power system: responsible for storing and providing electricity, including power sources (such as batteries), energy management systems, and chargers.
3. Auxiliary system: including auxiliary power source, power steering system, navigation system, air conditioner, lighting and defrosting device, wipers and radio, etc.
4. Motor: As the power source of electric vehicles, it is equivalent to the engine and gearbox of traditional cars and is known as the heart of electric vehicles.
5. Battery: The battery is one of the most important components of an electric vehicle, ensuring a continuous supply of power and directly determining the vehicle's range and lifespan.
6. Electronic Control System: The electronic control system can be regarded as the brain part of electric vehicles, responsible for commanding the operation of electronic components in electric vehicles. The in vehicle energy system is the core technology in the electronic control system, including battery management technology, in vehicle charging technology, DC/DC technology, and energy system bus technology.
The above are the main components of new energy vehicle parts. It should be noted that with the advancement of technology and changes in market demand, the accessories of new energy vehicles may be adjusted or updated.
