Abstract:

A portable solar battery charger comprises a photovoltaic array, a power regulator, a controller, and a battery. In one embodiment, the controller is configured to increase the charging current provided by the power regulator to the battery over time using discrete current levels. A comparator can compare the voltage of the photovoltaic array to a threshold, and provide the result to the controller. The controller can be configured to decrease the current to a previously selected level when the comparator indicates the voltage of the photovoltaic array is below a threshold, thereby improving the efficiency of the current delivery to the battery.
