The invention provides a storage battery device with higher charging and discharging capability. The battery device according to an embodiment includes at least one battery module including a batterypack including a plurality of battery cells, a battery monitoring circuit that detects the voltages and temperatures of the battery cells, and a temperature adjustment unit that adjusts the temperatures of the plurality of battery cells; a heating unit that heats and outputs a medium supplied to the temperature adjustment unit; a cooling unit that cools and outputs the medium supplied to the temperature adjustment unit; and a battery management circuit having a temperature detector and a battery temperature control unit. The temperature detector can communicate with the battery monitoring circuit and the outside and detect the temperature of the medium. The battery temperature control unit controls the heating unit and the cooling unit to adjust the temperature of the medium so as to control the temperatures of the battery cells on the basis of the values of internal resistances corresponding to the values of the temperatures and voltages of the battery cells received from the batterymonitoring circuit, so that the internal resistances of the plurality of battery cells reach a predetermined range.
