POWER STORAGE UNIT, CORRECTION METHOD FOR CAPACITY VALUES OF STORAGE BATTERIES, AND POWER STORAGE SYSTEM

摘要

A power storage unit is provided which is able to facilitate recalibration and which is able to supply power even while recalibration is being performed. A method for correcting the capacity values of storage batteries, and a power storage system are also provided. In the power storage unit, a control unit turns ON a portion of the switches to connect a portion of the storage batteries to the charge and discharge path for correction, and corrects the capacity value of the portion of storage batteries by charging and discharging the portion while the other switches are turned OFF to disconnect the other storage batteries from the charge and discharge path.
