BATTERY PACK TEMPERATURE CONTROL STRUCTURE FOR ELECTRIC VEHICLES

摘要

The purpose of the present invention is to suppress an increase in size of a battery pack case in the vehicle longitudinal direction as well as in the vehicle width direction, even if a heavy-current disconnecting switch and a temperature control unit are mounted within the battery pack case. This invention comprises: a battery module (2) mounted in an inner space of the battery pack case (1); an SD switch (4) that disconnects, by a manual operation, a battery high-power circuit in the battery module (2); and a temperature control unit (3) mounted in the inner space of the battery pack case (1) which produces a temperature-controlled air to be blown to the battery module (2). The SD switch (4) is disposed in an upper space position within the inner space of the battery pack case (1). The temperature control unit (3) is disposed in a space position lower than the heavy-current disconnecting switch and in a position overlapping with the heavy-current disconnecting switch in the vehicle vertical direction.
