Now electric vehicles have become a travel tool for thousands of families, and electric vehicle batteries, as the power source of electric vehicles, are also in the rapid development, the current mainstream batteries on the market are lead-acid batteries, lithium batteries, graphene batteries, what are the difference between them? How to choose it? Come and see it quickly!

Take it, Take heaven and earth as the camp and coexist with nature. Start your journey with electricity. Follow your heart to travel with electricity freely. Unlock various new outdoor playing methods. Enjoy the comfort and passion of life freely.

The BMS battery management system is an indispensable component of power and energy storage battery pack, which plays important functions such as ensuring safety, extending the service life, and estimating the remaining power, to a certain extent, it improves the battery life and reduce the loss caused by battery damage.

Lead-acid batteries belong to the eighth category of dangerous goods, transportation requires a license, and export lead-acid batteries must be specially packaged (qualified packaging certificate), otherwise the customs will not pass.

Lithium iron phosphate has the characteristics of long life, safe use, large capacity, green environmental protection, etc., and its demand continues to increase in the fields of power batteries and energy storage. At present, the energy storage system with lithium iron phosphate batteries has become the mainstream choice in the market. In the first seven months of 2022, China's domestic lithium iron phosphate energy storage accounted for more than 90% of the electrochemical energy storage field.

LiFePO4 is poor in electrical conductivity because of the low diffusion coefficient of Lithium ion. The current approach is to make the particles smaller or even nanoscale. Through shortening the migration path of Li+ and electrons, the speed of charging and discharging is increased (theoretically, the migration time is inversely proportional to the square of the migration path). But this brings a series of difficult problems to battery processing. Let’s take a look at how to solve the problem of coating uniformity of lithium iron phosphate battery .

Older-fashioned batteries may require us to add electrolyte frequently. However, with the advancement of technology, maintenance-free batteries​ have now been used on a large scale. But even so, the battery is still a vulnerable part in the use of the vehicle, and the service life of the maintenance-free battery is generally about 4 years.

​Besides lead-acid battery, there are still some electric cars using lithium batteries, but when replacing lithium batteries, we found that noboday wants to use old lithium batteries, why does this happen?

What is the real life of lithium iron phosphate? In fact, the life of a lithium battery pack is nearly the same, whether it is lithium iron phosphate battery or ternary lithium battery, the real service life is related to the user's method and protection. In this article, let's talk about what is the real life of lithium iron phosphate battery pack.

Waste lead-acid batteries can be recycled. With the development of new energy vehicles, a large number of waste lead-acid batteries flow into the market, so how to recycle these waste lead-acid batteries? Let's have a look!

Therefore, in view of the needs of most users, this article will sort out relevant matters needing attention about "how to choose electric vehicle battery" to avoid being cheated.

The battery should be checked regularly after a period of use, and the corresponding maintenance should be done according to the quality of the mains power supply.
