Abstract:
1. A cooling apparatus of a battery module, the cooling apparatus comprising: a housing including an accommodation part accommodating the battery module and an air passage through which external air passes, a plurality of battery cells being on a bottom surface of the battery module; a first heat transfer member fixed to the housing and having a first surface exposed to the air passage, a second surface of the first heat transfer member being opposite the first surface and parallel to the bottom surface of the battery module; and a second heat transfer member disposed between the battery module and the first heat transfer member, a first surface of the second heat transfer member overlapping and being parallel to each of the bottom surface of the battery module and the second surface of the first heat transfer member, a distance between the battery module and the first heat transfer member being normal to the first surface of the second heat transfer member wherein when a temperature of the battery module increases, the second heat transfer member contacts only a center portion of the bottom surface of the battery module, the center portion of the bottom surface of the battery module overlapping a predetermined number of battery cells positioned equidistantly with respect to two sidewalls of the battery module.
