Abstract
A battery module includes a battery module housing, cells disposed in the battery module housing, and spacers disposed between adjacent cells. Each spacer is electrically insulating and includes a body portion having a curvilinear, for example elliptical, outer peripheral shape. The body portion is suspended from the cell housing by hangers, and overlies a central region of a cell housing surface corresponding to large deflection due to cell growth. In addition, the body portion is spaced apart from a periphery of the cell housing surface.
Claims20
A spacer for maintaining a constant gap between cells of a battery module, the spacer comprising
- a body portion is a plate having an elliptical peripheral shape, and
- a hanger that protrudes from a peripheral edge of the body portion and is configured to mechanically connect the body portion to an external structure,
- wherein the spacer is formed of an electrically insulating material.
A battery assembly comprising a cell and a spacer supported on the cell, wherein the cell includes
- a housing;
- an electrode assembly disposed in the housing;
- and
- a terminal that is disposed on an outer surface of the housing and electrically connected to an electrode of the electrode assembly;
- and
- the spacer is disposed on the outer surface of the housing and includes a body portion having an elliptical peripheral shape.
A battery module comprising a battery module housing, cells disposed in the battery module housing, and a spacer disposed between a pair adjacent cells, wherein the cells each include
- a housing;
- an electrode assembly disposed in the housing;
- and
- a terminal that is disposed on an outer surface of the housing and electrically connected to an electrode of the electrode assembly, wherein the spacer includes a body portion having an elliptical outer peripheral shape.
