Abstract

A battery structure includes a plurality of batteries each made of lithium-ion secondary battery; and a plurality of arrangement portions in which the plurality of batteries are arranged. The plurality of arrangement portions are divided into two groups of: a upper heat transfer group having heat transfer orders higher than a center value of the heat transfer orders, where the heat transfer orders are respective amount of heat transfer from the batteries being ranked in descending order; and a lower heat transfer group having the heat transfer orders lower than the center value. A battery among the plurality of batteries showing the highest value of a lithium deposition tolerance which represents a degree of lithium being unlikely to deposit during charge/discharge operation, is disposed in a high tolerance arrangement portion in the plurality of arrangement portions, the high tolerance arrangement portion belonging to the upper heat transfer group.
