The present inventions, in one aspect, are directed to techniques and/or circuitry to determine the state of charge of a battery/cell using data which is representative of a partial relaxation time of the battery/cell. In another aspect the present inventions are directed to techniques and/or circuitry to determine the state of charge of a battery/cell using data which is representative of an overpotential or full relaxation time of the battery/cell. In yet another aspect the present inventions are directed to techniques and/or circuitry to adaptively charge a battery/cell using data which is representative of a state of charge of the battery/cell. |
