Why do Batteries Need to be Balanced?
During the use of batteries, imbalances caused by various factors such as differences in internal resistance and self discharge rates can lead to issues such as capacity decay, shortened lifespan, and reduced safety of the battery pack.
Taking the battery pack of electric vehicles as an example, a battery pack is usually composed of hundreds or thousands of battery cells connected in series or parallel. If the capacities of these individual batteries are not consistent, during the charging process, the battery with the smaller capacity may be fully charged first, while other batteries have not yet been fully charged. If charging continues, small capacity batteries may experience overcharging, leading to overheating, bulging, and even safety accidents such as combustion or explosion.

The Importance of Balance
In the fields of electric vehicles, energy storage systems, UPS, etc., the battery balancing effect improves system stability and reliability, reduces maintenance costs, and extends overall service life. For example, in the field of electric vehicles, battery balancing technology can make the power and voltage of each battery cell similar, avoid overcharging and overdischarging, stabilize the performance of the battery pack, improve the reliability of vehicle operation, and synchronize the aging of battery cells to reduce replacement frequency. For example, the maintenance cost of a certain brand of electric vehicle can be reduced by 30% -40%, and battery performance degradation can be slowed down. For example, the lifespan of Nissan Leaf battery packs can be extended by 2-3 years, and the range can be increased by 10% -15%.
