<P>PROBLEM TO BE SOLVED: To provide a battery pack that inexpensively cools inside the battery pack without causing an increase in the number of components. <P>SOLUTION: The battery pack 100 is provided with each secondary battery 4 formed by laminating a plurality of unit batteries respectively having a positive electrode and a negative electrode, each of current collector electrodes 21, 23 respectively provided on each end face of each secondary battery 4 located in a lamination direction of the unit batteries, and each of terminals T1, T2 respectively formed to each of the current collector electrodes 21, 23 so as to be externally protruded from the side face of each secondary battery 4. Also, the pack is respectively connected with each of charge/discharge conductive members U1, U2. A refrigerant is supplied toward each of the terminals T1, T2 so as to cool each of the terminals T1, T2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
