    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 m 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.

    Abstract: A battery pack includes a plurality of batteries, a housing, a circulation path, and a blower. The circulation path includes a bottom wall side path formed between lower faces of the batteries and a bottom wall which is the bottom side of the housing. The bottom wall is provided with a plurality of beams arranged in parallel for reinforcing the housing, and the batteries are arranged on the beams. The bottom wall side path is formed as a space surrounded by the lower faces of the batteries, the bottom wall, and the beam. The width of the bottom wall side path formed between adjacent beams is set to be larger than the width of one beam.

    Abstract: In a battery pack, unit cells, an internal cooling fan and a drive motor are arranged in an inside space of a housing. The drive motor drives the internal cooling fan to supply cooling air. The cooling air circulates in the inside space of the housing to cool the unit cells. Radiation fins are formed on at least one specific exterior surface of the housing. The specific exterior surface has a superior radiation capability which is higher than that of each of the other exterior surfaces of the housing. The cooling air is supplied in turn surfaces of the unit cells and interior surface of the housing corresponding to the exterior surface on which the radiation fins are formed.

    Abstract translation: 在电池组中，单元电池，内部冷却风扇和驱动电动机布置在壳体的内部空间中。 驱动电机驱动内部冷却风扇供应冷却空气。 冷却空气在壳体的内部空间中循环以冷却单元电池。 辐射翅片形成在壳体的至少一个特定的外表面上。 具体的外表面具有比壳体的其他外表面的每一个高的优异的辐射能力。 冷却空气被提供给单元电池和壳体内表面的表面，其与形成有辐射翅片的外表面相对应。
