Abstract
A battery unit temperature management device may include a battery unit that can be charged and discharged, a heater that operates due to electricity supply from the battery unit and heats a heat exchange medium that exchanges heat with the battery unit, a changing structure that changes a heat transfer capacity between the battery unit and the heat exchange medium, and a controller that controls the heating of the heat exchange medium by the heater and the change of the heat transfer capacity by the changing structure. When a temperature Tw of the heat exchange medium does not reach a first temperature which is equivalent to a temperature of the battery unit while the heat exchange medium is heated by the heater, the controller may make the heat transfer capacity smaller than that when the temperature of the heat exchange medium has reached the first temperature.
