STORAGE-BATTERY MANAGEMENT DEVICE, METHOD, AND PROGRAM

摘要

When a storage-battery management device according to an embodiment of the present invention manages a storage battery system equipped with a power adjustment device and a storage battery device provided with a plurality of battery cells, a cell-voltage detection unit detects the voltage of the battery cells, and a charge/discharge power suppression unit suppresses, on the basis of the voltage of the battery cells, the discharge power or charge power of the storage battery device using the power adjustment device, such that the cell voltage of the battery cells during charging or discharging becomes equal to and does not exceed a cell-voltage limit value for the battery cells during charging or discharging. As a result, the cell voltage of the battery can be maintained within an appropriate operation range, without losing energy capacity of the battery system.
