Abstract
A battery management system having configurable batteries is disclosed. The battery management system generally includes (a) one or more cell control units, each cell control unit configured to control and/or balance a charge in a plurality of battery cells, and (b) a master controller in electrical communication with cell control unit(s). The cell control unit(s) as a whole include one or more switches, configured to be electrically connected to a first battery cell of a plurality of battery cells, and a resistor, a capacitor or an inductor electrically (i) connected to one switch and (ii) connected or connectable to a second battery cell. The master controller is configured to open or close each switch. The configurable battery generally includes a plurality of battery cells and switches configured to connect or disconnect the plurality of battery cells in a configurable or predetermined manner.
