Abstract
A system and method for a safe and reliable high voltage battery module is disclosed. A weight and cost efficient structure to connect a plurality of cell-brick assemblies in series and/or parallel and protect against a thermal runaway event, resulting in improved manufacturability and reliability.
Claims15
An assembly comprising:
- a first cell;
- a second cell adjacent to the first cell;
- a third cell adjacent to the second cell;
- and
- a thermal management strip contacting a first portion of the first cell, a second portion of the second cell, and a third portion of the third cell, wherein the thermal management strip comprises a thermally conductive layer, a first insulating layer, and a second insulating layer, the thermally conductive layer being disposed between the first insulating layer and the second insulating layer.

A battery module comprising:
- a first plurality of cells forming a first row of the battery module;
- a second plurality of cells forming a second row of the battery module;
- a plurality of insulative wraps, each wrap in the plurality of insulative wraps disposed around a respective cell in the first plurality of cells and the second plurality of cells;
- and
- a plurality of conductive thermal management strips, a first conductive thermal management strip in the plurality of conductive thermal management strips in contact with a first portion of insulative wraps in the battery module, the first conductive thermal management strip configured to apportion heat among a first portion of cells corresponding to the first portion of insulative wraps in response to a cell in the first portion of cells entering thermal runaway.
2 more elements
A battery module, comprising:
- a plurality of cells;
- and
- a plurality of thermal management strips, each thermal management strip in the plurality of thermal management strips thermally coupled to a respective portion of cells in the plurality of cells, wherein:
- each thermal management strip in the plurality of thermal management strips is configured to apportion heat among the respective portion of cells in the plurality of cells when a cell in the respective portion of cells enters a thermal runaway event, and
- apportioning excess heat among the respective portion of cells in the plurality of cells results in each cell in the respective portion of cells increasing in temperature, while maintaining a temperature below a thermal runaway threshold.
