What are the techniques for selecting electric vehicle batteries?

Below we will summarize some tips on how to choose an electric vehicle battery. 1. First look at the brand to solve the problem of how to choose electric vehicle batteries. First of all, we need to look at the battery brand. The reputation of the big brand battery is guaranteed and the quality is good. Of course, you must buy a genuine battery, and the big brand's after-sales service is also in place. For example, Kangyang battery, a well-known brand in my country, is the leader of high-end batteries. Both the quality of the battery and the after-sales service are guaranteed, so that people can use it with peace of mind and be trustworthy! 2. Check the appearance. Secondly, we need to look at the appearance of the battery. A good electric vehicle battery shell is very thick (for example: Kangyang black gold battery's unique manufacturing process makes the shell more solid and has extremely high heat dissipation performance.) In addition, the terminal block It is large and the printing on the battery is clear. In addition, find the authentic ones. The fake and inferior batteries are still different in appearance from the genuine ones, so you must carefully identify them. Generally, the batteries of major brands have anti-counterfeiting marks, and the anti-counterfeiting marks are unified. The anti-counterfeiting codes are all 16 digits and are unique. Each battery has a separate number. 3. Performance test After checking the appearance of the battery, perform a performance test on the battery. An electric vehicle battery with excellent performance has small internal resistance and small monomer voltage error. Internal resistance: measure the battery voltage during high current discharge, the smaller the voltage drop is, the better; monomer voltage: the battery voltage should be consistent with the battery voltage after the battery is charged and saturated, and the error should be less than 0.05 volts. Every Kangyang black gold battery will undergo strict performance testing to ensure that each Kangyang black gold battery has the best performance! 4. Look at the after-sales service. The last point to note is: look at the after-sales service of the battery. The quality of the electric vehicle battery is the most important thing, and the after-sales service is also necessary. Pay attention to the incomplete after-sales service of the electric vehicle battery purchased. Kangyang has been recognized by consumers for its perfect after-sales service system, and it has welcomed a batch of batches of customers to visit the company to discuss cooperation.
