Abstract:
A device according to an embodiment of the present disclosure relates to a device for controlling the output of a rechargeable electricity storage device. The output control device is provided with: an acquisition unit which acquires a state of charge of the electricity storage device at the current point in time; and a control unit which sets an operation range of the state of charge of the electricity storage device. The control unit performs at least one of gradually decreasing processes of a first gradually decreasing process whereby, if the acquired state of charge is greater than or equal to a lower limit value of the operation range, a maximum discharge power of the electricity storage device is gradually decreased over a predetermined grace period, and a second gradually decreasing process whereby, if the acquired state of charge is less than or equal to an upper limit value of the operation range, a maximum charge power of the electricity storage device is gradually decreased over a predetermined grace period.
