<P>PROBLEM TO BE SOLVED: To reduce pressure loss of a heating medium and also to reduce variation of temperature control efficiencies to each battery cell, in a battery module. <P>SOLUTION: First to third heat exchangers 31-33 are formed by connecting each of heat exchange parts 31a, 31b, 31c, 32a, 32b, 32c, 33a, 33b and 33c in series along the circulation direction of a heating medium. In a battery module M1, a heating medium circulation mechanism R1 configured by connecting the first to third heat exchangers 31-33 with each other in parallel by a supply pipe 51 is provided so that the heating medium parallelly flows into each inflow port 41 of the first to third heat exchangers 31-33. <P>COPYRIGHT: (C)2013,JPO&INPIT |
