Abstract: Systems, methods and apparatus for charging a two-terminal portable electronic device. In one example, the system, method, and apparatus include detecting, with a detection circuit, the two-terminal portable electronic device and electrically coupling the two-terminal portable electronic device to a multi-pin universal serial bus connector when the two-terminal portable electronic device is coupled to a receptacle provided by a charger; and charging, with an activation circuit, the two-terminal portable electronic device using a configuration channel terminal of the multi-pin universal serial bus connector upon detection of the two-terminal portable electronic device.

Abstract: Methods and apparatus for controlling charge current in a battery pack containing cells of disparate types are disclosed. The methods include receiving a charge current for charging a battery pack that includes one or more battery cells of a first cell type, and one or more battery cells of a second cell type. Each battery cell of the first cell type has a first impedance and a first charge current limit. Each battery cell of the second cell type has a second impedance greater than the first impedance and a second charge current limit greater than the first charge current limit. The methods include reducing, by a respective current control circuit associated with each battery cell of the first cell type, the amount of the received charge current through the battery cell of the first cell type to an amount less than the first charge current limit.
