Electric storage battery i.e. traction battery, for electric or hybrid vehicle, has case including self-supporting structure for maintaining compressed cells in housing arranged in structure, where housing utilizes outer shape of cell

摘要

The battery has a case containing prismatic cells (3i) having same dimension. The cells are arranged in an adjacent manner while maintaining compression inside the case. The case includes a self-supporting structure (21) for maintaining each compressed cell in an individual housing (7i) that is arranged in the self-supporting structure. The housing utilizes outer shape of the cell. The cells are arranged in a row in which each cell is adjacent to that of the same row.
