Abstract
A battery management device that manages a battery includes: multiple voltage detection circuits each connected to a corresponding one of a plurality of battery cells; and multiple discharge circuits each connected to a corresponding one of the battery cells. The battery management device causes the battery cell whose voltage difference from a reference voltage is equal to or greater than a predetermined first threshold and less than a second threshold that is greater than the first threshold to be discharged while a system of the vehicle is stopped, and causes the battery cell whose voltage difference is equal to or greater than the second threshold to be discharged at least either while the system is stopped or while the system is in operation.
