More Information
Summary: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.
