1. EV (Electric Vehicle) is the English abbreviation for electric vehicles. Although China's pure electric vehicle technology is already very mature, due to various reasons, it is still difficult for pure electric vehicles to achieve industrialization in the short term. Industry experts point out that the popularization of charging stations is the key to the industrialization of pure electric vehicles. At the same time, national industrial policies should provide a favorable application environment for pure electric vehicles and promote their industrialization process.
When hybrid vehicles are driving at low speeds, this mode is activated, and the vehicle can operate solely on the power provided by the battery without the intervention of the engine. The noise of the vehicle is almost eliminated, while achieving zero emissions. This is also one of the significant differences between a fully hybrid system and a mild hybrid system. When the EV button on the hybrid vehicle is pressed, the system will limit the engine start, meaning only the electric motor will drive the vehicle, thus avoiding noise and exhaust pollution to the surrounding environment.
2.HEV stands for Hybrid Electric Vehicle, which is a hybrid electric vehicle. HEV is a compromise between traditional and fully electric vehicles: it simultaneously utilizes the internal combustion engine (which can be designed smaller) of traditional vehicles and the electric motor (PMSM or asynchronous motor) of a fully electric vehicle for hybrid driving (including battery and inverter loops), reducing the demand for fossil fuels, improving fuel economy, and achieving energy-saving, emission reduction, and greenhouse effect mitigation effects. Toyota Prius and Honda Inset are the two giants in HEV production.
3.PHEV refers to a plug-in hybrid electric vehicle in the field of new energy vehicles, which is a specially designed hybrid electric vehicle that charges through plug-in charging. Generally, a dedicated power supply pile is required for power supply. When there is sufficient electrical energy, the vehicle is driven by an electric motor. When there is insufficient electrical energy, the engine will participate in the driving or power generation process.
Summary:
Electric vehicle (EV) refers to a vehicle that travels on the road using an electric motor or traction motor. There are three main types of electric vehicles: the first is directly powered by an external power station; The second type is initially powered by electricity stored from an external power source; The third method is to use on-board generators, such as internal combustion engines (hybrid electric vehicles) or hydrogen fuel cells. Electric vehicles include electric cars, electric trains, electric trucks, electric airplanes, electric boats, electric motorcycles, motorcycles, and electric airships.
If the power source is a battery, and the energy of the battery comes from an external power source, this is a pure electric vehicle or battery electric vehicle (BEV); If the electricity comes from a generator driven by an internal combustion engine, it is a hybrid electric vehicle (HEV); If it comes from solar panels, it is a solar car; If it comes from fuel cells, it is a fuel cell vehicle (FCEV). In addition to internal power supply, it can also come from external power sources, such as trams.
