POWER STORAGE DEVICE AND METHOD FOR CONTROLLING POWER STORAGE DEVICE

摘要

A power storage device provided with: a plurality of serially-connected power storage units having at least one cell; cell balance units connected in parallel to each of the power storage units with a switch interposed therebetween; and a controller for charging the plurality of power storage units at a first constant current value, and, when the power storage unit having the highest voltage from amongst the plurality of power storage units reaches a first potential, performing a control so as to connect the power storage unit having the highest voltage with the cell balance unit corresponding to the highest voltage and switch the charging current to a second constant current value which is smaller than the first constant current value.
