HEV
HEV is the abbreviation of Hybrid Electric Vehicle, meaning hybrid vehicle, which refers to a hybrid vehicle between gasoline and electricity.
The HEV model is equipped with an electric drive system on the traditional engine drive for hybrid drive, and its main power source relies on the engine. But adding a motor can reduce the need for fuel.
Generally, the motor relies on the motor to drive at the start or low speed stage. When accelerating suddenly or encountering road conditions such as climbing, the engine and motor work together to provide power to drive the car. This model also has an energy recovery system that can recharge the battery through this system when braking or going downhill.
BEV
BEV, short for EV, the English abbreviation of BaiBattery Electrical Vehicle, is pure electric. Pure electric vehicles use batteries as the entire power source of the vehicle and rely only on the power battery and drive motor to provide driving power for the vehicle. It is mainly composed of chassis, body, power battery, drive motor, electrical equipment and other systems.
Pure electric vehicles can now run up to about 500 kilometers, and ordinary household electric vehicles can run more than 200 kilometers. Its advantage is that it has high energy conversion efficiency, and can achieve truly zero exhaust emissions and no noise. The disadvantage is that its biggest shortcoming is battery life.
The main structures include a power battery pack and a motor, which are equivalent to the fuel tank and engine of a traditional car.
PHEV
PHEV is the English abbreviation of Plug in Hybrid Electric Vehicle. It has two independent power systems: a traditional engine and an EV system. The main power source is the engine as the main source and the electric motor as the supplement.
It can charge the power battery through the plug-in port and drive in pure electric mode. When the power battery is out of power, it can drive as a normal fuel vehicle through the engine.
The advantage is that the two power systems exist independently. It can be driven as a pure electric vehicle or as an ordinary fuel vehicle when there is no power, avoiding the trouble of battery life. The disadvantage is that the cost is higher, the selling price will also increase, and charging piles must be installed like pure electric models.
REEV
REEV is a range-extended electric vehicle. Like pure electric vehicles, it is powered by a power battery and an electric motor drives the vehicle. The difference is that range-extended electric vehicles have an additional engine system.
When the power battery is discharged, the engine will start to charge the battery. When the battery is charged, it can continue to drive the vehicle. It is easier to confuse it with HEV. The REEV engine does not drive the vehicle. It only generates electricity and charges the power battery, and then uses the battery to provide power to drive the motor to drive the vehicle.
