Abstract:
A battery pack includes an arrangement of battery cells organized in battery groups connected in series, with each group having one or more battery units connected in parallel, and each battery unit comprising one or more series-connected battery cells connected to a battery switch. Charging of the battery pack uses pulse charging. The charging pulses provided to the battery units can be determined based on one or more measured characteristics of battery cells comprising the battery unit so that charging of the battery units can be optimized according to those characteristics. The charging pulses provided to each battery group are timed so that there is an uninterrupted flow of charging current through all the battery groups at all times.

Claim (Index 1):
A system comprising:\n a battery pack comprising a plurality of series-connected battery groups, each battery group comprising a plurality of parallel-connected switched battery units, each switched battery unit comprising one or more series-connected battery cells connected to a battery switch; and a controller to produce a plurality of pulsed switching signals to control the battery switches in the battery pack, each pulsed switching signal corresponding to one of the battery switches, wherein during charging of the battery pack:\n each pulsed switching signal comprises a series of pulses having ON times that are determined based on one or more measured characteristics of the battery unit associated with the corresponding battery switch to optimize charging of the battery cells comprising the battery unit, wherein charging of the battery cells comprising each battery unit in the battery pack is optimized according to measured characteristics of the battery unit, and \n one or more battery switches in each battery group are in a CLOSED state to provide a path for an uninterrupted flow of charging current through the plurality of series-connected battery groups of the battery pack at all times during charging of the battery pack.
