Abstract: A battery pack for an electric vehicle has a cooling structure in which a coolant introduced through a first cooling channel cools cells and is then discharged through a second cooling channel. The cooling structure has a U-type structure in which the coolant is introduced and discharged in opposite directions. An entrance of the first cooling channel and an exit of the second cooling channel satisfy an equation in relation to an entrance flow rate and an exit flow rate. Since the temperature deviation among cells is set very small, the life of a battery pack may be elongated. Also, since a ratio of an exit area to an entrance area of a cooling channel may be quantitatively calculated according to an equation, it becomes very easy to design a battery pack.
