Abstract:
Systems and methods may place a battery in a first constant voltage charging mode and monitoring a diminishing current of the battery while the battery is in the first constant voltage charging mode. Additionally, the battery may be placed in a constant current charging mode when the diminishing current falls to a first predetermined threshold. In one example, a rising voltage of the battery is monitored while the battery is in the constant current charging mode and the battery is placed in a second constant voltage charging mode at an end of the charge cycle in response to the rising voltage reaching a second predetermined threshold. Moreover, a charge current corresponding to the constant current charging mode may be adjusted based on a charge capacity of the battery.
