Abstract
A multi-cell battery system is disclosed including a plurality of battery sub-assemblies stacked together along a longitudinal axis, and an electrical connector between the battery sub-assemblies. A heat exchange passageway passes across the electrical connector to cool the battery system. An exemplary electrical connector includes a plurality of heat transfer features to promote cooling of the battery system.
Claims26
A battery system having a longitudinal axis, the battery system comprising:
- a plurality of prismatic battery cells including:
- a first cell having a first terminal extending from the first cell;
- and
- a second cell having a second terminal extending from the second cell, the second cell arranged longitudinally of the first cell along the longitudinal axis;
- an electrical connector that electrically couples the first terminal of the first cell to the second terminal of the second cell;
- and
- a heat exchange passageway across the electrical connector.
A battery system comprising:
- a first framed sub-assembly including a first plurality of prismatic battery cells, each of the first plurality of prismatic battery cells having a terminal;
- a second framed sub-assembly removably coupled to the first framed sub-assembly and including a second plurality of prismatic battery cells, each of the second plurality of prismatic battery cells having a terminal;
- an electrical connector that electrically couples the first plurality of prismatic battery cells to the second plurality of prismatic battery cells;
- and
- a heat exchange passageway across the electrical connector.
A method of assembling a battery system, the battery system including a longitudinal axis and a plurality of prismatic battery cells including a first cell and a second cell, the method comprising the steps of:
- arranging the second cell longitudinally of the first cell along the longitudinal axis;
- electrically coupling a first terminal of the first cell to a second terminal of the second cell with an electrical connector;
- and
- passing a heat exchange medium across the electrical connector to cool the first cell and the second cell.
