PROBLEM TO BE SOLVED: To enable greater enhancement of the warming efficiency than a prior art when a battery in a battery module is indirectly warmed.SOLUTION: Battery modules 20, 20 are joined to each other in a horizontal direction to be paired, and an air duct 26 intercommunicating with a supply slit 27a provided to the side surface of a cover 23 is formed between the battery modules 20, 20. The heater 42 is provided in a space 40 which is provided below the air duct 26 and opened downwards in the vertical direction so that the heater 42 is brought into contact with a battery holder 22. Each of the paired battery modules 20, 20 is provided with a partition member 44 on the side surface of a cover 23 at the side opposite to the joint side so as to form a space 45 which houses an end portion of the battery holder 22 and is opened downwards in the vertical direction. The partition member 44 is configured to extend to the lower side of the battery holder 22 in the vertical direction.SELECTED DRAWING: Figure 7 |
