Differences Between BEV, HEV, PHEV, EREV and FCV Between BEV

I. Pure Electric vehicle (BEV)

This is what we often refer to as a pure electric vehicle, i.e., only a lithium battery (no combustion engine) provides power with the help of an electric motor to drive the car forward. driving the vehicle at low cost and emissions;It is less polluting than thermal power; green energy .

II. Hybrid Electric Vehicle (HEV)

Hybrid Electric Vehicle (HEV) here refers to a traditional hybrid vehicle, which is powered by a fuel engine and an electric motor in parallel. Generally the battery capacity is small and cannot be charged externally, and the energy of the battery is obtained through energy recovery. No mileage anxiety compared to pure electric vehicles . Low fuel consumption compared to traditional internal combustion engine vehicles and longer range .

III. Plug-in Hybrid Electric Vehicle (PHEV)

Unlike HEVs, PHEVs have an on-board power battery that can be recharged by an external power source. Power is provided by the fuel engine and electric motor. This model can switch between pure electric, pure fuel and hybrid fuel-electric modes in real time, etc. PHEVs are the perfect transition from pure petrol to pure electric cars, fuel saving and electricity saving, fill up a tank of fuel ran 1250 km. Handling and comfort, the motor-driven model, with no gearbox, is smooth and powerful.

IV. Extended-Range Electric Vehicles (EREV)

Generate electricity through fuel, charge the battery and the electric motor drives the car. The electric motor drives the car and has the good characteristics of an electric car. It can be equipped with smaller capacity batteries, low weight and low cost. Because it can generate electricity through fuel, there is no mileage anxiety. The disadvantage is that it cannot provide power at the same time as HEV fuel and electricity, and the power is not as good as HEV.

V. Fuel Cell Vehicles (FCV)

Fuel cell vehicles (FCVs) provide the energy needed for driving by converting the chemical energy of fuel into electric energy, and the vehicle is driven by an electric motor. Currently, the main type of fuel is hydrogen. The energy of fuel cell is replenished by adding fuel, so the time is similar to refuelling. In addition, the fuel cell energy conversion process is highly efficient, noiseless, and has no pollutant emissions. The biggest difficulties at present are the difficulty in obtaining fuel, the difficulty in storing and transporting fuel, and the scarcity of hydrogen refuelling stations.
