Thermal Management methods:
Insulation or conductivity

Thermal management of batteries in H&EVs is essential for the effective operation of motors in all climates and environments and is the main focus in the design of battery modules and packs for pre-production prototypes or serial production. Design thinking and technologies are constantly evolving to address these various issues. Design and material engineers are addressing the trade-offs between performance, functionality, volume, mass, cost, maintenance, and safety issues. There are two possible approaches in ensuring a balance between all these performance factors, both based on optimizing TMS.

• The first approach is based on the thermal insulation of the cells to avoid overheating and propagate temperature increases to other cells, while at the same time insulating individual batteries to limit the impact of cold environments on its temperature.

• The second approach is to use thermally conductive materials that can evacuate heat from the cells.
