High volt battery for storing electrical driving power for partial electrical propelled vehicles, has inserts including specific thermal expansion approximately equal to thermal expansion of cell block associated with metallic components

摘要

The battery has multiple cells (3), where each cell is clamped between two cell holders (2). The clamped cells are joined together to form a cell block (1) and held together by a clamping apparatus e.g. tie rods. The cell holders are made of plastic material, and elastomer inserts are embedded in each cell holder. The inserts include a specific thermal expansion approximately equal to the thermal expansion of the cell block associated with metallic components such as clamping apparatus or cooling plates (5, 6).
