A battery assembly (100) of the invention includes a secondary battery (4) formed by stacking a plurality of unit battery cells having a cathode and an anode, collector electrodes (21, 23) provided on respective end surfaces of the secondary battery (4) positioned in the stacking direction of the unit battery cells; and terminal portions (T1, T2) formed at the collector electrodes (21, 23), protruded outward from a side surface of the secondary battery (4), to which conductive members (U1, U2) are connected for charging and discharging. A coolant is supplied to the terminal portions (T1, T2) to cool the terminal portions (T1, T2). |
