Abstract
An object of the present invention is to provide a control device and a control method for a storage battery, which calculates an appropriate maximum allowable input/output power that suppresses deterioration of the storage battery while suppressing deterioration of power performance of a vehicle when a current is continuously charged or discharged. When it is detected that charging or discharging is continuously performed over a predetermined duration time with respect to the maximum allowable charge power and the maximum allowable discharge power which can be input and output during the calculated predetermined duration time, the value of the maximum allowable charge power or the maximum allowable discharge power communicated to a vehicle controller on the basis of the state of charge or discharge is reduced based on the time during which charging or discharging is actually continued.
