Plug in hybrid electric vehicle, the following is a detailed explanation about plug-in hybrid electric vehicles:
1. Definition: Plug in hybrid vehicles are a new type of vehicle that combines the advantages of traditional fuel vehicles and pure electric vehicles, and can charge the onboard power battery through an external power source.
2. Working principle: Plug in hybrid vehicles not only have the core components of traditional cars such as engines, transmissions, and transmission systems, but also are equipped with battery packs, electric motors, and control circuits. During the driving process, the vehicle can charge the power battery through energy recovery. At the same time, when using engine driven mode and driving at a relatively stable speed, a portion of the torque output by the engine will drive the motor to generate electricity and charge the power battery. According to the hybrid mode of the hybrid system, PHEV's hybrid system is mainly divided into three types: series, parallel, and hybrid, each with different working principles and characteristics.
3. Characteristics and advantages: Plug in hybrid vehicles have a longer pure electric driving range and can also operate in the same way as regular hybrid vehicles. The combination of pure electric drive system and hybrid drive system can reduce the emissions of harmful gases and greenhouse gases, greatly reduce the fuel consumption of the whole vehicle, and improve fuel economy. Plug in hybrid vehicles can use the external public power grid to evenly charge the onboard power battery, reducing dependence on oil, while also improving the efficiency of power plant generators, peak shaving and valley filling, and alleviating power supply pressure.
