Abstract
A system includes a first power converter, a second power converter, a first battery having a time to end of discharge (EOD) and coupled to output a current to the first converter, a second battery having a time to EOD and coupled to output a current to the second converter, and a control circuit coupled to the first converter and the second converter. The control circuit is configured to monitor the times to EOD of the first battery and the second battery, and in response to the times to EOD of the first battery and the second battery not being substantially equal, control the first converter to adjust the current drawn from the first battery to change a rate of decrease of the time to EOD of the first battery. Other example systems and methods for substantially matching a time to EOD of a plurality of batteries are also disclosed.
