What is the purpose of balancing the lithium battery pack? As a Ni-MH Battery Pack Supplier, I would like to share with you. The application of lithium battery packs in the market and in various fields is not uncommon. The most important link in the charging and discharging process of lithium battery packs is the equalization link. Equalization has the function of equalizing the voltage of the lithium battery pack, so as to achieve the full capacity of the battery pack. The function of charging and fully discharging enables the battery pack to exert its maximum effect.

Lithium battery packs are made up of multiple batteries. Since the batteries are independent individuals, there will be some slight differences. After the combination is welded, it will be affected by the direction and length of the connecting piece and the welding process. 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 cell. This situation will cause damage to the cell and ultimately As a result, the entire set of lithium batteries cannot work effectively.

The equalization treatment of lithium battery pack can solve this problem. When there is a large difference in the value of a single string of lithium-ion batteries, the equalization voltage of the battery is controlled by the BMS, which can maximize the service life of the lithium battery pack. To put it bluntly, the balance is to maintain all lithium battery packs in all normal categories to ensure overall safety.

The balance link is to ensure that the input and output of the lithium battery pack are reasonable to each lithium battery, so that they can be used reasonably and effectively without damage. At present, the two most common equalization methods for lithium battery packs are energy-consumption equalization and transfer-energy equalization.

Lithium battery equalization technology means that after the lithium batteries are grouped, the overall performance of all batteries in the battery pack is brought to the same level through human intervention. The purpose is to ensure that the performance of the lithium battery pack can be fully utilized and to ensure the safety of the battery during use.
