<P>PROBLEM TO BE SOLVED: To provide a battery module which has a structure suitable for simplification and maintains high battery performance of each power generation element while suppressing abnormal increase of an internal pressure in a housing part of the power generation elements, and to provide a beneficial ventilation control valve used in the battery module or the like. <P>SOLUTION: In a battery module, multiple battery containers 13, in which power generation elements are respectively housed, are provided so as to be strung together. The battery module includes communication holes 18, each of which is provided at each partition wall 12 of the adjacent battery containers 13 to make communication between the battery containers 13, and ventilation control valves, each of which has a valve body 30 that changes an open area of each communication hole 18 according to a difference in internal pressures of the adjacent battery containers 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
