摘要： A battery structure for an electric vehicle includes a plurality of columnar component cells and a substantially square battery casing for accommodating the component cell. The battery casing includes a casing body consisting of an upper casing, a lower casing and an intermediate casing interposed between the upper casing and the lower casing, and a pair of side covers fitted to both ends of the casing body. In the battery casing, a plurality of rib walls are formed to support the component cells and to divide an interior of the battery casing into a plurality of compartments in the longitudinal direction of the battery casing. Further, the battery casing has air holes formed in top and bottom walls of the battery casing for circulating cooling air in the compartments vertically. In operation, since the cooling air flows vertically through the upper and lower air holes in the respective compartments defined by the rib walls, it is possible to extend the cooling air over the whole lengths of the component cells, so that the cooling for the component cells can be effected to enhance the cooling capability of the whole batteries.
摘要翻译：电动车辆的电池结构包括多个柱状元件单元和用于容纳元件单元的基本上为方形的电池壳体。电池壳体包括由上壳体，下壳体和介于上壳体和下壳体之间的中间壳体构成的壳体，以及装配到壳体主体两端的一对侧盖。在电池壳体中，形成多个肋壁以支撑组件单元并且将电池壳体的内部沿着电池壳体的纵向方向分成多个隔室。此外，电池壳体具有形成在电池壳体的顶壁和底壁中的气孔，用于使隔室中的冷却空气垂直。在操作中，由于冷却空气通过由肋壁限定的各个隔室中的上部和下部空气孔垂直流动，因此可以在整个组件单元的整个长度上延伸冷却空气，使得组件的冷却可以实现电池以增强整个电池的冷却能力。

摘要： A spirally coiled electrode assembly has positive and negative electrodes each including a web-like collector coated with an active material on opposite surfaces thereof, and separators disposed between the positive and negative electrodes. A plurality of rectangular leads extend from opposite sides of the web-like collectors in directions perpendicular to a direction in which the positive and negative electrodes and the separators are wound. Positive and negative terminals are connected to the rectangular leads extending from the respective opposite sides of the web-like collectors. The spirally coiled electrode assembly, the rectangular leads, and the positive and negative terminals are housed in a cylindrical casing whose opposite ends are closed by respective caps. The positive and negative terminals are fixed to the caps, respectively.
