Principle of new energy vehicle subsystem

Working principle of new energy vehicles;

Electric drive control system is the nerve center of electric vehicle, which connects and controls auxiliary systems such as motor and battery. According to the working principle, the electric drive control system can be divided into three parts: vehicle power module, electric drive main module and auxiliary module.

The electric energy generated by electrochemical reaction between hydrogen in fuel cell and oxygen in air under the action of catalyst is used as the main power source to drive the car.

The battery converts chemical energy into electrical energy through electrochemical reaction. For electrochemical reactions, hydrogen is usually used as a reducing agent and oxygen as an oxidizing agent. Therefore, most of the earliest fuel cell electric vehicles directly use hydrogen fuel, and hydrogen can be stored in the form of liquefied hydrogen, compressed hydrogen or metal hydride. Extended data:

Advantages:

1. After adopting hybrid power, the maximum power of internal combustion engine can be determined according to the average required power. The engine is relatively small and works under the best working conditions of low fuel consumption and less pollution. Because the internal combustion engine can work continuously and the battery can be charged continuously, its journey is the same as that of an ordinary car.

2, because of the battery, it is very convenient to recover kinetic energy when going downhill.

3. In busy urban areas, the internal combustion engine can be turned off and driven only by batteries to achieve "zero" emissions.

4. With the internal combustion engine, it is convenient to solve the high energy consumption problems such as air conditioning, heating and defrosting encountered by pure electric vehicles.

5, you can use the existing gas station to refuel without investment.

6, can keep the battery in good working condition, without overcharge and overdischarge, and prolong its service life.
