ADJUSTING DEVICE, BATTERY ASSEMBLY, AND ADJUSTING METHOD

An adjusting device that is connected to a load and to a plurality of storage battery units that are connected together in parallel and that adjusts voltage differences among the plurality of storage battery units includes: for each of the storage battery units, a switch that is provided between a storage battery unit and the load that is turned ON during detection intervals for detecting current from the storage battery unit, a detection means that detects the current supplied from each of the storage battery units during the detection interval, and an adjusting means that, based on the detection results of the detection means, controls the ON/OFF states of switches during the adjustment intervals for adjusting voltage differences such that the voltage differences among the plurality of storage battery units are decreased.
