Compared with traditional vehicles, new energy vehicles have different structures and working principles.

Different from the "three big parts" of traditional cars, the "three electric" system consisting of "motor, battery and electronic control" is the core component of new energy vehicles, including new intelligent networking systems such as human-vehicle interaction, which are all new demands generated by the new energy vehicle industry.

New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles.

The composition of electric vehicle includes: electric drive and control system, driving force transmission and other mechanical systems, as well as working devices to complete the established tasks. Electric drive and control system is the core of electric vehicle, and it is also the biggest difference from internal combustion engine vehicle. The electric drive and control system consists of driving motor, power supply and motor speed regulating device. Other devices of electric vehicles are basically the same as internal combustion engines.

Pure electric vehicle (BEV) is a kind of vehicle that uses a single battery as the power source of energy storage. It uses the battery as the power source of energy storage, and provides electric energy to the motor through the battery to drive the motor to run, thus promoting the car to run.

Hybrid electric vehicle (HEV) refers to a vehicle whose drive system consists of two or more single drive systems that can run at the same time. The driving force of the vehicle is provided by a single driving system or by a plurality of driving systems according to the actual driving state of the vehicle. Due to different components, layout and control strategies, hybrid electric vehicles have many forms.

Fuel cell electric vehicle (fuel? Cells? Electric? FCEV(vehicle) is an automobile driven by electric energy generated by electrochemical reaction between hydrogen in fuel cell and oxygen in air under the action of catalyst.

A hydrogen engine car is a car driven by a hydrogen engine. The fuel used in general engines is diesel or gasoline.

The fuel used by oil and hydrogen engines is gaseous hydrogen. Hydrogen engine car is a kind of vehicle that really realizes zero emission. It emits pure water, which has the advantages of no pollution, zero emission and abundant reserves.

Although the current sales volume of special purpose vehicles accounts for a relatively small proportion in the overall sales volume, it is expected to become the main force of future market growth with the increase of policy support in the future.
