BATTERY MODULE

摘要

A battery module is provided to improve the cooling efficiency of unit cells by supplying a cooling medium stably between a unit cell and a hole and to minimize the temperature deviation between unit cells by controlling the interval between a unit cell and a cooling medium. A battery module comprises a plurality of unit cells(120); a frame(100) which supports the unit cells and has a hole(112) where the unit cells are inserted; and a projected support(115) which is installed between the hole and the unit cells to support the unit cells. Preferably the support is continued from the one end of the hole to the other end; and the length of the hole is identical to the length of the unit cell.
