Abstract:

Devices and methods are disclosed for checking the state of health of rechargeable batteries. An electronic device comprises a plurality of rechargeable batteries and a controller, wherein the controller comprises a battery fuel gauge for performing a battery state of health check. The controller is configured to direct charge to connected loads and to transfer charge from the battery being checked to another battery during a battery state of health check. An example method comprises charging one battery to a full state, leaving another battery in a depleted state, and performing a state of health check on the battery in the full state while transferring charge via an intermediate controller from the battery in the full state to the battery in the depleted state.
