A battery cell short circuit detection device includes: a control unit that controls operation of a direct current-direct current converter; a first acquisition unit that acquires a storage rate of the battery; a second acquisition unit that acquires a current flowing into the battery and a current flowing out of the battery when the direct current-direct current converter is operating; a third acquisition unit that acquires a terminal voltage value that is a voltage that appears at a terminal of the battery when the direct current-direct current converter is not operating; and a determination unit that determines presence or absence of the short circuit between the battery cells based on an average storage rate indicating an average value of the storage rate of the battery, an average inflow current value indicating an average value of the current flowing into the battery, and the terminal voltage value.
