Abstract
Battery pack chargers for charging a battery pack include one or more battery pack receiving portions, a power control module, and a power conversion unit. The one or more battery pack receiving portions receive and interface with the battery pack. The battery pack includes one or more battery cells. The power control module provides power to the one or more battery pack receiving portions using pulse amplitude modulation (PAM). The power conversion unit converts the power received from the first external source to a first DC power used for charging the one or more battery cells.
