POWER SUPPLY DEVICE, POWER SUPPLY METHOD, CONTROL DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a power supply device capable of using the power of a storage battery for vehicle driving even in a building, driving the vehicle while using the power of the storage battery in the building, and furthermore preventing increase in the introduction cost thereof.SOLUTION: A power supply device 10 comprises a mounting device 11, a charge/discharge device 12, and a control device 13. The mounting device 11 is detachably mounted with one or a plurality of storage battery modules 12 selected from the plurality of storage battery modules 12. The charge/discharge device 12 can charge and discharge the storage battery modules 21 mounted on an electric vehicle 20 and the storage battery modules 21 mounted on the mounting device 11. The control device 13 controls the charge/discharge device 12. When the deterioration degree of the storage battery module 21 reaches a first reference value, the control device 13 notifies the charge/discharge device 12 of recommendation of using the storage battery module 21 for purposes other than driving of the electric vehicle 20. When the deterioration degree reaches a second reference value, the control device 13 notifies the charge/discharge device 12 of recommendation of using the storage battery module 21 as a recycled material.
