Multi-level battery management

Methods and systems supply uninterrupted power to a load using a backup battery module. A driver circuit connects the load and the backup battery module such that the operational range of the load voltage is narrower than the operational range of the battery voltage. Different charging and discharging paths of the driver circuit may be used to limit the DC bus voltage to values lower than the battery voltage. The proposed systems and methods can increase power efficiency and decrease the cost of power supply and conversion operations.
