NOVELTY - Inside the battery casing (2), battery cells are spaced in a frame, forming cell modules (4). The cell modules are each arranged on fastening components penetrating the battery casing. These components are designed as spacers (12) between the modules and form a supportive unit with the casing. The components are rod profiles and each supports two opposite walls of the battery casing. The fastening frame of the cell modules forms a part of the supportive unit.    USE - A battery or battery pack for electrically-powered- or hybrid vehicles.    ADVANTAGE - The design satisfies prime requirements of vehicle batteries. These include resistance to acceleration forces, shocks and vibration in all directions, compact construction and adequate cooling, preventing thermal overload. In the new design, because the separators of the cell modules form a supportive unit with the battery casing, all inertial forces from the cells are transmitted into the casing. This assures that no individual cell vibration occurs. No relative movement can take place between the cells and the casing.    DETAILED DESCRIPTION - Battery cells within a frame are compliantly-supported by it, along one or more spatial axes. The cell modules are joined by electrical connectors. These connectors are made of a light metal, especially aluminum. They are rectangular plates with a surface-to-volume ratio (m2/m3) of 0.3 - 2.0 m-1. The cell modules are arranged in series, in rows within the battery casing. The series arrangement is such that intermediate spaces between cells of adjacent rows are flush with each other, or inter-connect. Fastening components of series cell modules arranged adjacently and/or above one another, are connected together as a grid structure. The battery casing has both ventilation and venting openings. These allow both forced- and convective ventilation of the battery casing. The rods are T-shaped in cross section. The battery cells are constructed with electrodes pocketed in plastic, with separators between them and electrolyte-filled. Each has two flexible lugs joined to the connectors.
