Question 1 How to classify new energy vehicles? 2 What are the requirements of new energy vehicles for power batteries?

What are the categories of new energy vehicles? classify

1. Blade Electric Vehicle (BEV) is a vehicle that uses white battery as energy storage power. It takes the storage battery as the power source of energy storage, and provides electric energy to the motor through the storage battery to drive the motor to run, thus promoting the automobile to run.

2. Hybrid electric vehicle (HEV) refers to a vehicle whose driving system consists of two or more single driving systems that can run at the same time, and the driving force of the vehicle is provided by the single driving system or multiple driving systems according to the actual driving state of the vehicle. Due to different components, layout and control strategies, hybrid electric vehicles have many forms.

3. Fuel cell electric vehicle (FCEV) is an automobile driven by electrochemical reaction between hydrogen and oxygen in the air under the action of catalyst. Fuel cell electric vehicle is essentially a pure electric vehicle, and the main difference lies in the different working principles of power batteries. Generally speaking, fuel cells convert chemical energy into electrical energy through electrochemical reaction, and the reductant required for electrochemical reaction generally adopts hydrogen and the oxidant adopts oxygen. Therefore, most of the earliest developed fuel cell electric vehicles directly use hydrogen fuel, and hydrogen can be stored in the form of liquefied hydrogen, compressed hydrogen or metal hydride.
