The difference between extended range hybrid and plug-in hybrid

Power source and driving method: The main difference between extended range hybrid and plug-in hybrid lies in their power source and driving method. Extended range hybrid vehicles mainly rely on the power battery to drive the motor to move the vehicle forward, and the engine is only used to charge the battery and does not directly participate in driving. Plug in hybrid vehicles can be driven directly by the engine when the battery is low, or they can be charged and driven in pure electric mode.

 

Power source and driving method: The extended range hybrid engine does not directly drive the wheels, but is used to generate electricity to charge the battery, and the vehicle is completely driven by an electric motor. The plug-in hybrid engine can be used to generate electricity or directly drive the vehicle when the battery is fully charged, providing a longer pure electric range.

 

Structure and composition: The structure of extended range hybrid vehicles is relatively simple, mainly composed of power battery system, power drive system, vehicle control system, and auxiliary power system. Plug in hybrid vehicles include generators, engines, rectifiers, batteries, traction motors, mechanical transmission devices, etc.

 

Fuel consumption and efficiency: The engine of extended range hybrid vehicles is mainly used for power generation, and its working efficiency may not be as good as that of plug-in hybrid vehicles. The latter can be directly driven by the engine in a low power state, improving work efficiency.

 

Maintenance cost and selection: The internal structure of extended range hybrid vehicles is simple, and the maintenance cost is relatively low. Plug in hybrid models, due to their complex internal structure, theoretically have a higher system failure rate and higher maintenance costs.
 

Progressiveness technology and environmental protection: Plug in hybrid has higher technical requirements, can achieve higher work efficiency and lower fuel consumption, and is more environmentally friendly than incremental hybrid.

In summary, both extended range hybrid and plug-in hybrid have their advantages. Extended range hybrid is suitable for consumers who pursue simple structures and lower maintenance costs, while plug-in hybrid is more suitable for users who pursue environmental protection and high efficiency due to its higher work efficiency and lower fuel consumption. The choice of type depends on individual needs and preferences.
