BATTERY TEMPERATURE ADJUSTMENT APPARATUS

摘要

A battery temperature adjustment apparatus includes a case for housing battery cells and a fan device disposed in the case for blowing air to cool the battery cells. The battery temperature adjustment apparatus further includes a circulation passage formed inside the case, the air blown from the fan device being sucked into the fan device after having circulated through the circulation passage and exchanged heat with the battery cells, a discharge passage which makes communication between inside and outside of the case, a first inflow passage which constitutes part of the circulation passage and through which the air having exchanged heat with the battery cells is sucked into the fan device, a second inflow passage which makes communication between inside and outside of the case, and an air distribution permitting/inhibiting device which permits and inhibits air distribution through at least one of the discharge passage and the second inflow passage.

1. A battery temperature adjustment apparatus comprising:
a case for housing battery cells; a fan device disposed in the case for blowing air to cool the battery cells; a circulation passage formed inside the case, the air blown from the fan device being sucked into the fan device after having circulated through the circulation passage and exchanged heat with the battery cells; a discharge passage which makes communication between inside and outside of the case, part of the air circulating through the circulation passage being discharged after having exchanged heat with the battery cells; a first inflow passage which constitutes part of the circulation passage, and through which the air having exchanged heat with the battery cells is sucked into the fan device; a second inflow passage which makes communication between inside and outside of the case to allow air outside the case to flow therethrough; and an air distribution permitting/inhibiting device which permits and inhibits air distribution through at least one of the discharge passage and the second inflow passage.
