    Tips: What is an active battery balancer?

    An active battery balancer is a device designed to manage and maintain the uniformity of charge and discharge among individual cells within a battery pack. Batteries often consist of multiple cells, and variations in their capacities or health can lead to uneven energy distribution, reducing overall efficiency and lifespan. The active battery balancer addresses this issue by actively redistributing energy between cells, ensuring that they remain balanced in terms of voltage and state of charge. Unlike passive balancers that rely on resistors or other simple mechanisms, active balancers use electronic circuitry and control algorithms to actively transfer energy between cells. This promotes optimal performance, enhances safety, and extends the life of the battery pack, making active battery balancers crucial components in applications such as electric vehicles and renewable energy systems.
