Title: BATTERY PACK TEMPERATURE CONTROL STRUCTURE FOR ELECTRIC VEHICLES
Abstract:
To improve temperature uniformity of battery modules housed in a battery pack case, and to keep low the maximum height of the battery pack case. A battery pack temperature control structure for electric vehicles comprises: a first battery module (21), second and third battery modules (22, 23), a temperature control unit (3), and a ventilation duct (9). The height dimensions for the second and third battery modules (22, 23) housed and arranged in the vehicle front area of an internal space of the battery pack case (1) are set lower than the height dimensions for the first battery module (21) housed and arranged in the vehicle rear area thereof. One end of the ventilation duct (9) is connected to a ventilation port (35a) in the temperature control unit (3); the other end is arranged facing the upper area (21a) of the module front surface of the first battery module (21); and an air blowing opening (91) through which temperature-controlled air is blown towards the vehicle rear is formed at the other end position, and extends in the vehicle width direction along the module front surface upper area (21a).
