PROBLEM TO BE SOLVED: To provide a battery pack for driving an electric vehicle, the battery pack being designed such that a refrigerant pipe connection part can be attached to a cover after the cover is placed over the tray.SOLUTION: A battery pack 1 for driving an electric vehicle comprises: a tray 2 in which a battery module 5 and a heat exchanger 6 for cooling the battery module 5 are installed; a refrigerant pipe connection parts 3 provided at the ends of refrigerant pipes 31, 32 connected to the heat exchanger 6 and relaying the refrigerant pipes 31, 32 to pipes outside the driving battery pack 1; a cover 4 mounted opposite the tray 2 and having a fitting hole 45 in which each refrigerant pipe connection part 3 is fitted; a fastening member for fixing the refrigerant pipe connection part 3 to the cover 4; and displacing means 9 that enables the refrigerant pipe connection part 3 to be displaced in a direction in which this connection part is fitted in the fitting hole 45, while the cover 4 is placed over the tray 2. While the cover 4 is placed over the tray 2, the refrigerant pipe connection part 3 is fixed to the internal surface of the cover 4 from outside the cover 4 by the fastening member.SELECTED DRAWING: Figure 6
