What type of battery is the electric car?

1. At present, the batteries of electric vehicles include ternary lithium batteries, lithium iron phosphate batteries and nickel-hydrogen batteries. Among them, Ni-MH battery is the most stable, lithium ferrous phosphate is the safest and ternary lithium has the largest capacity. 2, ternary lithium battery: good at cooperation, the same weight, the largest power. However, when the members are tightly packed together, the temperature is a bit high. Therefore, ternary lithium batteries have strict requirements for heat dissipation. In order to ensure safety, every battery must have a safety device.

3. Lithium iron carbonate battery: Most car companies are very popular. Although the same weight of electricity is not as good as ternary lithium battery, it has good thermal stability, is not easy to get angry, and the cost of heat dissipation components is much lower. In addition, it also has the advantages of high energy density, small volume, long battery life and good safety.

4. Hydrogen battery: generally used in hybrid vehicles, its performance is worse than that of lithium batteries. This kind of battery has a good memory, and it can be clearly remembered whether it is overcharged or discharged. Therefore, Ni-MH battery requires high charging and discharging time, and the power must be kept in a fixed range. Therefore, Dianjun suggests that you recharge as much as possible after each use, and it is a one-time recharge. Don't charge for a while before charging.

5. Hydrogen fuel cell: high energy conversion efficiency, zero pollution, long service life and not cheap. Besides, people who have studied chemistry are familiar with it: hydrogen is flammable, and if it is transported or stored in large quantities, it has high requirements, high risk factor and great security risks.

6. As the power source of electric vehicles, it has always been regarded as an important landmark technology for the development of electric vehicles, and it is also an important bottleneck restricting the development of electric vehicles. Its performance is directly related to the cruising range of the whole vehicle.
