WIPO Patent Application WO/2016/147323
Kind Code:
A1
Abstract:
A battery unit of a storage battery system according to an embodiment of the present invention is provided with a plurality of battery modules which are provided with storage batteries, and which are connected in series. A bypass circuit is configured so as to enable a state to be set in which any battery module among the plurality of battery modules is bypassed, and the other battery modules are connected in series. When any of the battery modules is in a state of being bypassed by the bypass circuit, a voltage-compensation power converter, which is connected in series with the battery unit, compensates for the voltage drop of the bypassed battery module. Accordingly, provided is a large-scale storage battery system having a high number of series connections which is capable of improving the utilization rate of the storage battery modules during fallback operation.
