Abstract
A battery module for improving heat balance of a cell assembly provided in the battery module includes a cell assembly having at least three battery cells stacked along a stacking axis such that at least one battery cell located at an interior position within the cell assembly along the stacking axis has a greater thickness along the stacking axis than a battery cell located at an outer side of the cell assembly. A module housing includes at least one sidewall and is configured to accommodate the cell assembly in an inner space defined by the sidewall.
Claims14
A battery module, comprising:
- a cell assembly having at least three battery cells stacked along a stacking axis, such that an inner direction is defined from an outermost side of the cell assembly towards a center of the cell assembly along the stacking axis, and an outer direction is defined from the center towards the outermost side of the cell assembly along the stacking axis wherein at least a first one of the battery cells located at an interior position within the cell assembly along the stacking axis has a greater thickness along the stacking axis than a second one of the battery cells located in the outer direction from the first one of the battery cells;
- and
- a module housing having at least one sidewall and configured to accommodate the cell assembly in an inner space defined by the sidewall.
