<P>PROBLEM TO BE SOLVED: To provide a secondary battery module which equalizes the temperatures between multiple battery cells. <P>SOLUTION: A secondary battery module includes: multiple battery cells 1 arranged therein; coolant vaporization layers 9, each of which is provided at a peripheral surface of each battery cell 1 and holds a vaporization coolant 3 supplied from a coolant supply source 4 to vaporize the coolant 3; temperature sensors 10, each of which detects the temperature of the battery cell 1; coolant detecting sensors 11, each of which detects if the vaporization coolant is supplied to the coolant vaporization layer 9 of the battery cell which is a detection object of the corresponding temperature sensor 10; and a control part 7 controlling the supply of the vaporization coolant 3 from the coolant supply source 4 to the coolant vaporization layer 9 or the supply stop based on the detection values of the temperature sensor 10 and the coolant detecting sensor 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
