Abstract: The disclosed embodiments provide a charging system for a portable electronic device. The charging system includes a first bidirectional switching converter connected to a first power port of the portable electronic device, a low-voltage subsystem in the portable electronic device, and a high-voltage subsystem in the portable electronic device and a second bidirectional switching converter connected to a second power port of the portable electronic device, the low-voltage subsystem, and the high-voltage subsystem. The charging system also includes a control circuit that operates the first and second bidirectional switching converters to provide and receive power through the first and second power ports and convert an input voltage received through the first or second power port into a set of output voltages for charging an internal battery in the portable electronic device and powering the low-voltage subsystem and the high-voltage subsystem.

Abstract: Systems and methods for power management are disclosed herein. In one disclosed embodiment, a battery charging system includes a battery charger for simultaneously charging a battery (and/or providing power to a system load) with multiple power sources, using a closed-loop charging servo target based on measurements taken by one or more gauges. In some embodiments, the multiple power sources may be utilized simultaneously according to a charging profile that specifies, e.g., one or more battery charging parameters, as well as according to determined priority levels for one or more of the multiple power sources coupled to the battery. In some embodiments, the priority level of a given power source is not fixed; rather, the priority level for the given power source may change based upon the characteristics of the given power source. In some embodiments, the priority levels for the multiple power sources are implemented using cascaded voltage target values.

Abstract: This disclosure describes a battery pack that includes a plurality of asymmetrical banks, with different capacities and/or voltages, and multiple taps, coupled to the corresponding banks, to power electrical loads. The battery pack also comprise a balancing circuit and a battery management unit. The battery pack may regulate voltages among the banks and/or balance the states of charge among the asymmetrical banks, by moving charges among the banks, by controlling one or more converters. The battery pack monitors the status of its banks and communicate with a host system via the battery management unit. Based on the monitored information and/or communication, the battery management unit generates control signals to drive the one or more converters.
