How does the engine of a hybrid car work?

Hybrid electric vehicle (HEV) is an auxiliary power-driven vehicle with electric motor as engine, which belongs to complementary technology. The power source is mainly the engine, and then it is equipped with a second power source battery. The combination of the two can save energy, and the motor of the auxiliary engine can generate strong and stable power during normal driving.

The most striking feature of hybrid electric vehicles is that they don't need to be charged, but only need to refuel. Because the battery of hybrid electric vehicle is small and the fuel tank is large, the battery is charged and discharged circularly during the engine running, braking, deceleration and starting, so as to achieve the purpose of energy saving.

Types of hybrid electric vehicles

1, plug-in hybrid vehicle

At present, the most common hybrid vehicles on the market are mainly due to their environmental protection and subsidies. Plug-in hybrid electric vehicles give consideration to both power and fuel consumption, and can enjoy preferential policies in most cities without being limited by too many cruising ranges.

2. Hybrid electric vehicles

This is a relatively mature hybrid car. The biggest feature of hybrid electric vehicles is fuel economy, because when starting to accelerate, with the help of electric motors, fuel consumption can be reduced. In addition, it can only be driven by motor at low speed, and the engine and motor share power at high speed.

3. Extended range hybrid vehicle

The principle of extended-range hybrid power is a kind of vehicle that uses engine to generate electricity and motor to drive. When the battery pack is fully charged, it operates in pure electric mode. When the battery pack is insufficient, the engine in the car is started to drive the generator to charge the power battery and provide power for the motor to operate (that is, extended range mode).
