Release Time:2017-12-02Browse Times:0

      Electric cars, simply speaking, are powered by electricity, and electric motors as power engines. But the various types of electric cars, such as EV, BEV, HEV, PHEV, EREV, FCV, etc., have been seen in various media.

      Today I will give you the popular science popularization.

      EV, known in English as Electric Vehicle, is an Electric Vehicle that covers all kinds of vehicles with Electric characteristics. Therefore, cars that are basically equipped with Electric motors can be collectively referred to as EV.

      BEV: Battery Electric Vehicle, Battery powered car.

    Working principle

   Model features

      Generally refers to pure electric vehicles, that is, only the battery provides energy supply, only the electric motor provides the power to drive the car forward.This type of car can achieve zero emissions from the driving process.

      Pure electric vehicles generally have a large capacity of battery, and provide ac slow charge and dc fast charging interface.

      Since such models can only rely on batteries for energy, a pure electric model can cause a lot of mileage anxiety for owners based on current battery performance and charging infrastructure.

      On behalf of the models

      Tesla series, nissan leaf, BMW i3, byd e6, e5, qin EV, baic EV series, jianghuai iEV series, saic E50, etc.

      HEV: Hybrid Electric Vehicle, or Hybrid Electric Vehicle. Generally speaking, fuel and batteries provide energy, fuel engines and electric motors.

    Model features

      The model typically has a small battery capacity and does not provide a charging port, and the battery's energy is recharged through the energy of the car's running process.

      The motor power of this model is also small, which provides the power to assist the fuel engine in starting and accelerating scenes. Because of the auxiliary of the motor, the large torque advantages of the motor can be fully utilized to improve the overall efficiency of the starting and accelerating process and reduce the overall fuel consumption of the vehicle significantly. There's no mileage anxiety because you rely on fuel for energy.

      PHEV: plug-in Hybrid Electric Vehicle, plug-in Hybrid Electric Vehicle. As the name suggests, PHEV's vehicle-mounted power cells can be charged through a socket, powered by batteries and fuel, and powered by fuel engines and motors.

      Different car manufacturers have different battery capacity, motor quantity and motor power configuration in PHEV. Different vehicle styles and characteristics are also formed.

    Model features

       This type of car can be driven by a combination of motor and fuel engine. For example, pure electric mode, pure fuel machine mode, motor refueling machine mixing mode, etc.

       In addition, PHEV can be used for charging and recharging, which can be used in pure electric mode when charging is convenient and electric power is sufficient. Energy saving and emission reduction also reduce the cost of the vehicle. When the battery is low enough to charge, the fuel will travel, and the journey will be secure.

       PHEV, which is generally configured with less battery capacity, is generally configured to only have a slow charging interface.

       Byd's qin, tang, saic ronay e550, e950, chery airize 7e, mitsubishi ou blue, etc.

       EREV: Extended-Range Electric Vehicle, which is a plug-in Electric Vehicle that USES fuel to generate electricity, recharges the battery, and motor drives the car.

    Model features

       Electric motor drive, have electric car good characteristic. It can be configured with smaller battery, small weight and low cost. Because you can generate electricity through fuel, there's no mileage anxiety.

       On behalf of the models

        BMW i3 extended range version, gac qiqi GA5. 

        FCV: Fuel Cell Vehicle, Fuel Cell Vehicle, which can be converted into electricity through the chemical energy of the Fuel, provides the energy required to drive, and is driven by the electric motor. The main fuel now is hydrogen.

    Working principle

    Model features

       Fuel cells are replenished by fuel, so time is close to refueling and can be done quickly. In addition, fuel cell energy conversion process is efficient, noiseless and free of pollutants.

       However, the biggest difficulty for fuel-cell vehicles is the difficulty of getting fuel, storing and transporting fuel, and adding fewer sites.

       Toyota Mirai and Honda Clarity

       I don't know if you have remembered.

       Can't remember, can collect oh first.
