  "textContent": "A battery management device (10) that performs equalization control on an electric vehicle battery (1) comprising a plurality of cells (2) includes a plurality of voltage detection circuits to detect the voltage of each of the cells, and a plurality of switchable discharge circuits (17) to selectively discharge each of the cells. A reference voltage is determined, based for example on the minimum voltage among the cells. The battery management device (10) causes a battery cell (2), whose voltage difference from the reference voltage lies between a predetermined first threshold and second threshold that is higher than the first threshold, to be discharged only while a system of the vehicle (100) is stopped (S155), and causes a battery cell (2) whose voltage difference is equal to or greater than the second threshold to be discharged both while the system of the vehicle is stopped and while the system of the vehicle is in operation (S165).",
