BATTERY PACK FOR ELECTRIC VEHICLE

摘要

PURPOSE: A battery pack for an electric vehicle is provided to lengthen the life of battery modules and eventually enhance the performance of the electric vehicle by cooling uniformly a plurality of battery modules within the battery pack. CONSTITUTION: A plurality of battery modules(2) are stored in a tray(1). A plurality of holes for flowing-in air and a plurality of holes(8) for flowing-out air are serially formed on one side and a top side of a pack cover(3), which is coupled to be dismounted to the tray(1) and prevents the dismounting of the battery modules(2) as well as realize the insulation with a vehicle body. A plurality of fans(5) are disposed to correspond to the air flowing-out holes(8) to discharge the air of an internal space formed by the tray(1) and the pack cover(3). The fans(5) are supported by a duct(4) which guides the discharged air toward outside.
