Abstract
A battery unit for hybrid or electric vehicles comprising a cell module including a plurality of storage cells, each accommodated in a prismatic cell casing with two large surfaces arranged parallel to each other and four narrow side surfaces. The prismatic cell casings with their parallel arranged large surfaces are stacked adjacent to each other. One of the narrow side surfaces, the cell casing bottom of each storage cell. A cooling device comprising a plate-shaped cooling body with one or several recesses, and one or several fastening mechanisms integrated into the cell module bottom that agree with a corresponding number of recesses of the cooling body, are configured to couple the cooling body to the cell module.
Claims10
A battery unit for hybrid or electric vehicles, comprising:
- a cell module, comprising a plurality of storage cells that each include a prismatic cell casing with two large surfaces arranged parallel to each other and four narrow side surfaces, each of the four narrow side surfaces being narrower than the two large surfaces, whereby
- the prismatic cell casings with their parallel arranged large surfaces are stacked adjacent to each other,
- one of the narrow side surfaces, in each case, of the prismatic cell casing forms the cell casing bottom of a storage cell, and
- the cell casing bottom of each storage cell, in each case, is part of the cell module bottom;
- a cooling device comprising a plate-shaped cooling body with a plurality of recess, and
- at least one fastening mechanism for each of the plurality of storage cells integrated into the cell module bottom to correspond with the at least one recess of the cooling body thereby fixing the cooling body to the cell module.
