Lithium battery packs are composed of multiple batteries. Since the batteries are independent individuals, there will be some slight differences. After the combination is welded, the direction and length of the connecting piece and the influence of the welding process will be affected. Increasing the generation of differences, each charge and discharge will increase the value of individual differences. When the value reaches a certain height, it will eventually lead to partial overcharge and overdischarge of the battery cell. This situation will cause damage to the battery cell. As a result, the entire set of lithium batteries cannot work effectively. Li-ion battery equalization can solve this problem. When a single string of lithium-ion batteries has a large numerical difference, the equalization voltage of the battery is controlled by the BMS, which can maximize the service life of the lithium battery;

What impact will an unbalanced lithium-ion battery pack have;

There is no need to use the equalization circuit on some lithium-ion battery packs with few strings and parallels. However, it is necessary to ensure that the group of single cells have high quality and consistency, and there is no problem with small charging and discharging currents. If the battery is If it belongs to a larger current discharge, it is very necessary to support equalization. Under normal circumstances, the life of a lithium battery pack without equalization function is lower than that of a lithium battery pack with equalization function;

What is the importance of equalizing charging to lithium battery packs?

When the high-current lithium-ion battery is used on some aircraft models or plant protection drones, due to the excessive current, the protection board is usually unable to be used during discharge, but it needs to be charged with a professional balance charger. Balance charging is safe for the battery Sex and longevity will have a great impact;
