working principle and characteristics of pure electric vehicles

working principle of pure electric vehicles: Compared with traditional fuel-powered vehicles, pure electric vehicles have safety, energy saving, maintenance and use With the characteristics of low cost, the major key systems that constitute pure electric vehicles can correspond to fuel vehicles. The following is the corresponding description of the major systems of pure electric vehicles and the corresponding systems of fuel vehicles.

Pure electric steamThe principle of car structure. Traditional internal combustion engine cars are mainly composed of four parts: engine, chassis, body and electrical equipment. Compared with fuel vehicles, the structure of pure electric vehicles mainly adds an electric drive control system and eliminates the engine. The transmission mechanism has changed.

The characteristics of pure electric vehicles are as follows: Environmental protection. Electric vehicles use power battery packs and motors to drive power. It will not produce exhaust gas during operation and does not exhaust pollution, which is very beneficial to environmental protection and air cleanliness. It can be said that it is almost "zero pollution".

The main feature of pure electric vehicles is its high voltage. Since the energy supply of pure electric vehicles is power batteries, the design of many systems on vehicles is also implemented around power batteries and high voltages.

Introduction to pure electric vehicles

Pure electric vehicles refers to cars that are completely driven by motors. The electric energy driven by the motor comes from the on-board rechargeable battery system or other energy storage devices. .

As the name implies, pure electric vehicles are vehicles driven purely by electricity without other energy, such as gasoline, diesel, etc. It can be used by household power supply.(Ordinary socket), special charging pile or specific charging place for charging to meet the daily driving needs.

Pure electric vehicles refer to passenger cars that use on-board batteries as the power output and drive wheels with motors to meet the requirements of road traffic, safety regulations and national standards. Because the environmental protection and energy consumption are relatively small compared with traditional fuel vehicles, its prospects are broadly optimistic, but it is not very popular at present and belongs to the development stage.

Classification of automobile generators

Automobile engines are machines that power cars and are the heart of automobiles, affecting the dynamics, economy and environmental protection of cars. According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrid engines.A diesel engine is an engine that burns diesel to obtain energy release.

The forms of automobile generators include: DC generators and alternators, which are divided into synchronous generators and asynchronous generators (rarely used); alternators can also be divided into single-phase generators and three-phase generators. There are many kinds of generators.

Automotive generators can be divided into DC generators and alternator generators. Because alternators are superior to DC generators in many aspects, DC generators have been eliminated.

The forms of automobile generators include: DC generators and alternators. Alternators are divided into synchronous generators and asynchronous generators (rarely used); alternators can also be divided into single-phase generators and three-phase generators. There are many kinds of generators.

The generator is the main power supply for automotive electrical equipment.During the normal operation of the car, the generator supplies power to electrical equipment other than the starter and charges the battery. Most of the generators used in cars are three-phase alternators.

How does the car generator work? How does the car generator generate electricity?

The generator is a mechanical equipment that converts other forms of energy into electrical energy. It is composed of turbines, steam turbines, wood The oil machine or other power machinery drive converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, and then converts it into electrical energy by the generator.

Automotive generators are also based on the principle of electromagnetic induction. When the external circuit energized the excitation winding through the electric brush to produce magnetismField, when the rotor rotates, the magnetic flux changes alternately in the stator winding. According to the principle of electromagnetic induction, it can be seen that alternating induced electromotive potential is generated in the three-phase winding of the stator.

The working principle of the automobile alternator is to connect and assemble the stator and rotor of the generator by the bearing and the end cover, so that the rotor can rotate in the stator and make the movement of cutting the magnetic line, thus generating an induced electric potential, which is led out through the terminal and connected to the loop, and an electric current is generated.

What is the working principle of the car generator?

1. Automobile generators are also based on the principle of electromagnetic induction. When the external circuit energized the excitation winding through the brush to generate a magnetic field, when the rotor rotates, the magnetic flux alternately changes in the stator winding.According to the principle of electromagnetic induction, it can be seen that alternating induction electromotive potential is generated in the three-phase winding of the stator.

2. The gasoline engine drives the generator to run and converts the energy of gasoline into electricity. In the cylinder of the gasoline engine, the mixed gas burns violently, and the volume expands rapidly, pushing the piston down to work.

3. The working principle of the automobile generator is that when the external circuit energizes the excitation winding through the brush, a magnetic field is generated, so that the claw pole is magnetized into n poles and s poles. When the rotor rotates, the magnetic flux changes alternately in the stator winding. According to the principle of electromagnetic induction, it can be seen that alternating induced electromotive potential is generated in the three-phase winding of the stator.

4. The working principle of the automobile generator is: a device made by the principle of electromagnetic induction and converted from kinetic energy into electrical energy.

5. The working principle of the automobile alternator is that the stator and rotor of the generator are connected and assembled by the bearing and the end cover, so that the rotor can rotate in the stator and make the movement of cutting the magnetic line, thus generating an induced electric potential, which is led out through the terminal and connected to the loop, and an electric current is generated.
