STORAGE BATTERY MANAGEMENT DEVICE, AND STORAGE BATTERY MANAGEMENT METHOD

摘要

A storage battery management device can efficiently charge a group of storage batteries connected in series. A storage battery management device (100) discharges or charges a plurality of storage batteries while switching the number of the storage batteries used or the number of the storage batteries connected in series or parallel as a connection mode. A chargeable electricity amount management unit (120) manages the storage batteries by calculating a chargeable electricity amount which is the amount of electricity that can be charged in each of the batteries from the current charge state to a full charge state. A chargeable electricity amount adjustment unit (130) controls the discharging or charging of the storage batteries such that the chargeable electricity amount of some or all of the storage batteries can reach a common target electricity amount.
