There are more and more new energy vehicles. New energy vehicles have a relatively large contribution to air quality. They are also supported by national policies. The new energy vehicle market has a bright future. So now speaking of the most important thing, traditional vehicles are mainly Fuel, new energy vehicles are mainly batteries, which give the car power and drive the car forward, so today the editor will introduce to you the car battery. What are the types of car batteries? How about your new energy car battery? Do you understand? Then let's take a look with the editor.

　　Batteries are an indispensable part of cars and can be divided into traditional lead-acid batteries and maintenance-free batteries.

　　Since the battery uses a lead-calcium alloy as the grid, the amount of water decomposition generated during charging is low, and the amount of water evaporation is also low. In addition, the shell is sealed and the sulfuric acid gas is released. Therefore, it is compared with traditional batteries. , It has the advantages of no need to add any liquid, the connection pile head, the electric storage time is long, etc.

　　What are the types of car batteries: role

　　It is a device that converts chemical energy into electrical energy. It is a DC power supply. Its functions are as follows:

　　(1) When starting the engine, provide powerful starting current (about 10A) to the starter.

　　(2) When the generator is overloaded, it can assist the generator to supply power to the electrical equipment.

　　(3) When the engine is at idle speed, supply power to electrical equipment.

　　(4) The battery is also a large-capacity capacitor, which can protect the electrical appliances of the car.

　　(5) When the generator terminal voltage is higher than the electromotive force of the lead-acid battery, part of the electric energy is converted into chemical energy and stored, that is, it is charged.
