in a battery pack that performs battery balancing. Circuitry that includes designs to balance cell charges during battery pack recharging may be either active or passive in its design, and is most often found in lithium-ion batteries, e.g., for laptop computers, electrical vehicles. etc.

Rationale

The individual cells in a battery pack naturally have somewhat different capacities, and so, over the course of charge and discharge cycles, may be at a different state of charge
