<p>PROBLEM TO BE SOLVED: To restrain the temperature rise of a battery effectively, during charging and discharging by having a liquid coolant flow through a space part formed between cells and arranging the battery in a tank storing the coolant such that the battery immerses the upper ends of its ribs in the coolant. SOLUTION: Respective cells are connected electrically together in series through connecting members, ribs 6 of the respective cells adjacent to each other are abutted against each other, and a space part opened at its upper and lower part is formed in a part between them. Water used as a coolant is filled in an inside tank 21, a modular battery 10 is installed in it, the height of the opening part of the inside tank 21 is set so as to be higher than the upper end of the rib 6 of each cell and lower than the upper surface of a lid. When a chiller 26 is started, the water in a cooling device 20 is circulated. That is, the water cooled by the chiller 26 flows into the space part through a via water supplying part 23, passes through the space part while absorbing the heat generated in each of the cells, overflows from the inside tank 21, and is supplied to the chiller 26 again by way of an outside tank 22 and a drain pipe 28.</p> |
