Abstract
An electrical energy storage unit and control system, and applications thereof. In an embodiment, the electrical energy storage unit (which may also be referred to as a battery energy storage system (“BESS”) includes a battery system controller and battery packs. Each battery pack has battery cells, a battery pack controller that monitors the cells, a battery pack cell balancer that adjusts the amount of energy stored in the cells, and a battery pack charger. The battery pack controller operates the battery pack cell balancer and the battery pack charger to control the state-of-charge of the cells. In an embodiment, the cells are lithium ion battery cells.
