<P>PROBLEM TO BE SOLVED: To provide a secondary battery module which can secure an adequate output by easily heating a unit battery even in an extreme environment. <P>SOLUTION: The secondary battery module includes a unit battery 11, a housing 12 in which the unit battery 11 is incorporated and which has an in-flow opening 12 and an exhaust opening 14 where a heat conductive medium enters and exits from, and a PTC heater 22 fixed at a side of the in-flow opening 13 and heating the heat conductive medium made to flow into the housing 12. With this, temperature of the secondary battery module is adjusted and a required output can be obtained by using the PTC heater 22 to easily heat the unit battery at need in a low temperature atmosphere. <P>COPYRIGHT: (C)2007,JPO&INPIT |
