What types of batteries do electric cars have?

There are now roughly three types of batteries for pure electric vehicles. The first is a lead-acid battery, which is an electrode made mainly of lead and its oxides. The electrolyte is a battery of sulfuric acid solution. Under the discharge state of lead-acid battery, the main component of positive electrode is lead dioxide, and the main component of negative electrode is lead; In the charging state, the main components of the positive and negative poles are lead sulfate.


The second type is hydrogen and nickel batteries. It uses a constant current charging method to charge the battery. According to the battery's ability to accept the current, the battery can be charged with different currents. There is no need to limit the voltage of the battery monomer during the charging process, and it can be quickly charged.

The third type is the lithium iron phosphate battery. It refers to lithium ion batteries that use lithium iron phosphate as a positive material. The positive materials of lithium ion batteries are mainly lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, and lithium iron phosphate. Among them, lithium cobalt acid is currently a positive material used in most lithium ion batteries.




Proper charging timing is critical to battery life. For example, a newly purchased electric car battery should be fully charged to 100 % for the first time. If 100 % of the battery is charged using a matching charger, the charging time will generally be 8-10 hours. Of course, some models are not necessarily. It is possible to charge according to the instructions of different battery types. Under normal circumstances, it does not exceed 12 hours. It is not recommended to run out of electricity for each charge. It is recommended to charge when the power is used up to about 70 %. After the first full charge, At the end of the battery, the vehicle is charged for a long time. This charge can be maintained for about 10 hours. The purpose is to allow the battery car to perform a complete cycle of chemical reactions.
