Abstract
An energy storage system with an energy storage cell coupled to a battery management system provided with a charge control circuit, a discharge control circuit and a maintenance discharge control circuit. The maintenance discharge control circuit including a voltage booster coupled to a constant current/constant voltage (CC/CV) regulator. Each of the charge control circuit, the discharge control circuit and the maintenance discharge control circuit are coupled between the battery management system and a host power rail. The voltage booster is operable to raise a voltage from the energy storage cell to a CC/CV regulator input voltage greater than a voltage of the host power rail, enabling the CC/CV regulator to provide a selected maximum voltage and corresponding maximum current to the host power rail during a maintenance discharge cycle of the energy storage cell.
