<p><P>PROBLEM TO BE SOLVED: To provide a battery module having excellent temperature control effect of a unit cell, and capable of minimizing a temperature difference between the respective unit cells, by improving a circulation structure of a refrigerant. <P>SOLUTION: This battery module includes: at least one battery assembly 11 configured by layering and arranging the plurality of unit cells 12; and a housing 20 incorporating the battery assembly 11, and circulating the temperature-controlling refrigerant. Thereby, in the battery module, the circulation structure of the refrigerant is improved, the temperature control effect of the unit cell 12 is improved, and the temperature difference between the respective unit cells can be minimized. In the battery module, the battery assembly 11 is disposed along a length direction of the housing 20, and a guidance part 30 guiding an advancing direction of the refrigerant toward the battery assembly is provided along an advance passage 23 inside the advance passage 23 of the refrigerant formed along the length direction of the housing 20. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
