Abstract
A battery management device for a battery that is incorporated in a vehicle includes a cooling fan configured to cool the battery and a controller configured to control the cooling fan. The controller is configured to calculate an amount of high-rate degradation damage which is an amount of degradation damage to the battery caused by high-rate charge or discharge, and is configured to restrict cooling of the battery by the cooling fan when the amount of high-rate degradation damage has reached or exceeded a predefined cooling restriction starting threshold, more strictly than when the amount of high-rate degradation damage is less than the cooling restriction starting threshold.
