The walls of the rectangular jacket are formed of rigid, foam-plastic material which thermally isolate the battery from the engine. Embedded in a wall of the jacket is a heat exchanger in which there is circulated a refrigerant fluid derived from the air conditioner installed in the vehicle. The heat exchanger acts to cool the battery to maintain the temperature of the electrolyte therein at a level at which the battery operates at optimal efficiency.

Why it's free to use
- Filed July 9, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 9, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 9, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
