Adjacent battery cells connected in devices are balanced by closing a first circuit to charge an energy storage device from a first battery cell and thereafter simultaneously opening the first isolated switch and closing a second isolated switch to cause the energy storage device to charge a second battery cell. A circuit includes an isolated switch that operates simultaneously to balance battery cells connected in series, and a battery system balances battery modules connected in series, the battery module including battery cells connected in series. The battery cells and modules can be balanced by hierarchical balancing of modules of the battery pack and component cells of the modules. |
