PARALLEL-CONNECTED ELECTRICITY STORAGE SYSTEM |
摘要 |
A parallel-connected electricity storage system in which a plurality of chargeable and dischargeable electricity storage elements are connected in series as an electricity storage element row and a plurality of the electricity storage element rows are connected in parallel includes an electricity-storage-element-voltage measuring device that measures an electricity storage element voltage of each of the electricity storage elements, an electricity-storage-element-state estimating device that estimates an electricity storage element state of each of the electricity storage elements, an electricity-storage-element-current measuring device that measures an electricity storage element current of each of the electricity storage element rows, a parallel-connected switch that performs connection and disconnection to and from the parallel-connected electricity storage system for each of the electricity storage element rows, and a parallel-connected-switch control means for turning on the parallel-connected switch on the basis of the electricity storage element voltage, the electricity storage element state, and the electricity storage element current. |
