PROBLEM TO BE SOLVED: To provide a method for suppressing variations in battery life by preventing a partial rise in temperatures of a plurality of secondary batteries configuring a secondary battery module.SOLUTION: A secondary battery module 101 comprises a plurality of secondary batteries 102 and a cooling mechanism for cooling the plurality of secondary batteries 102 by making a coolant flow through a coolant channel. The coolant mechanism can switch between the coolant channels so that the low-temperature coolant can be brought into thermal contact with the high-temperature secondary battery of the plurality of secondary batteries 102. |
