What is the purpose of the equalization treatment of lithium battery packs?


The application of lithium battery packs in the market and in various fields is not uncommon. The most important link in the process of charging and discharging lithium battery packs is the equalization link. Equalization has the function of equalizing voltage for lithium battery packs. , So as to achieve the effect of full charge and full discharge of the battery pack capacity, so that the battery pack can exert the maximum effect. As an Emergency Lighting Battery Supplier, share it with you.

What is the purpose of balancing the lithium battery pack?

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 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 packs 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 balanced link is to ensure that the input and output of the lithium battery pack are reasonable to each lithium battery, so that it 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 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.
