Battery Equalization System and Active Equalization Circuit Topology 2.1. Battery Equalization System As an energy management system, a battery equalization system [22, 23, 24, 25, 26] aims to reduce the energy differences among a battery pack’s cells, thereby improving the pack’s consistency.

What is a battery equalization system?

Battery Equalization System As an energy management system, a battery equalization system [22, 23, 24, 25, 26] aims to reduce the energy differences among a battery pack’s cells, thereby improving the pack’s consistency. Equalization strategies and topologies are both part of battery equalization systems.

What happens if a battery pack is equalized?

In the fast-charging process, the charging current is large, even if the battery pack is equalized, the equalization current is much smaller than the charging current, and the equalization effect is poor, the necessity for equalization is average.

Why should a series connected battery pack be equalized?

For a series-connected battery pack, when there is a consistency difference among the cells, it causes a decrease in the energy utilization and cycle life of the battery pack. Thus, the equalization of a series-connected battery pack is necessary.
