ADVANCED THERMAL MANAGEMENT TECHNOLOGIES
FOR LITHIUM-ION BATTERY MODULES
Transportation electrification is a priority for governments to reduce GHG emissions in Canada, especially with our unique renewable electricity resources. However, the adoption of electric vehicles is limited by the use of batteries, which carry a high cost, uncertainty of range, risk of thermal runaway and a life span that we are trying to optimize. All of these aspects are affected by the operating temperature of the batteries, so their effective thermal management is critical.
This project aims to accelerate the use of advanced thermal management methods based on the phase change of a coolant, in order to mitigate the challenges related to the design of high performance batteries. Two technologies will be developed and demonstrated: immersion and heat pipe cooling. More specifically, the implementation challenges for the immersion approach will be evaluated, including the boiling of a dielectric fluid directly on the cells. Also, fabrication methods for pulsed polymeric heat pipes (PPHP) will be developed and demonstrated. Tests will be conducted in the laboratory and subsequently on recreational vehicles. Models will also be developed to facilitate the implementation of these technologies in a wide range of battery modules for electric vehicles.
- Recreational Vehicles
Pave the way for the deployment of advanced thermal management methods among electric vehicle manufacturers in Canada and elsewhere, thereby supporting the electrification of transportation and a more sustainable society.
” This project will have a positive impact by supporting the electrification of transportation and contributing to a more sustainable society. ”
