Electric car battery, what kind of battery is an electric car battery

1.First use a multimeter to test whether there is voltage in the battery, if the voltage is there, it can be charged, if there is no voltage in the shelf life can be replaced.

2.Check the line for damage.

3.If it is not within the expiration date, it is recommended to buy a bottle of electrolyte and put it into the battery and recharge it will save you a lot of money.

4..In the future, the electric vehicle will be fully charged, and it will be charged and discharged at least once a month.

It is that your battery has been put for too long and has a serious loss of power General battery should be fully charged when stored to deal with this situation to you It is recommended that you go to a nearby repair shop to see your battery, if it can be replaced with the manufacturer within the warranty period.

You open the battery compartment to check whether the connecting cable between the batteries is broken.

When the battery is placed vertically, the electrolyte is easy to precipitate, the electrolyte is corrosive, and it is likely to break at the place of the binding post.

It was the rat that bit the thread off. Go and fix it, and if you want to fix it, take it apart and take a look.

At present, the batteries of electric vehicles include ternary lithium batteries, lithium iron phosphate batteries and nickel-metal hydride batteries. Among them, nickel-metal hydride batteries are the most stable, lithium ferrous phosphate is the safest, and ternary lithium batteries are the largest.

Ternary lithium battery: good at cooperation, the same weight has the maximum power. However, the components are tightly packed together, and the temperature is a bit high, so ternary lithium batteries have strict requirements for heat dissipation. To ensure safety, each battery must have a safety device.

Lithium iron carbonate battery: loved by most car companies. Although the same weight of electricity is not as good as ternary lithium battery, it has good thermal stability, is not easy to ignite, and the cost of heat sink parts is much lower. In addition, it has the advantages of high energy density, small size, long battery life and good safety.

Hydrogen: Generally used in hybrid vehicles, the performance is worse than that of lithium batteries. This kind of battery has good memory, and can be clearly remembered by overcharging and discharging.

Therefore, nickel-metal hydride batteries have high requirements for charge and discharge time, and the power must be kept within a fixed range. Therefore, Dianjun recommends that you try to charge it as much as possible after each use, and fully charge it once. Don't charge it after a while.

Hydrogen fuel cell: high energy conversion efficiency, zero pollution, long life, low energy. In addition, 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 coefficients, and large safety risks.

As the power source of battery electric vehicles, rubber infiltration 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.
