PROBLEM TO BE SOLVED: To further improve uniformity of an internal pressure of each secondary battery by restraining a pressure loss generated to each secondary battery of a battery module, as well as arrange wiring cables of various apparatuses mounted to the battery module so that they are difficultly influenced by heat generation of a secondary battery.SOLUTION: A battery module 1 is provided with three pressure coupling pipes 2 to which unit batteries C of 10 cells are connected via a connection tube 5, and the pressure coupling pipes 2 are coupled with each other via a coupling tube 6. Also, the pressure coupling tube 2 comprises a duct section 21 communicated with inside of each unit battery C, and a cable location section 22 for locating wiring cables of various apparatuses. By this constitution, inside of each unit battery C is communicated with each pressure coupling pipe 2, so as to make an internal pressure of each unit battery C uniform. Also, the wiring cables of the various apparatuses are arranged at the cable location section 22, so as to restrain influences on the wiring cables due to heat generation of the unit battery C and the like. |
