Thermal Management of the Lithium/Metal Sulfide Electric Vehicle

Thermal management studies of the Lithium-Aluminum/Metal Sulfide Battery demonstrate the need for a light weight, high thermal efficiency case for electric batteries. Calculations based upon the rectangular configured MK IA battery using vacuum-foil insulation, show that the heat loss rate goal of 400 watts can be met. Experimental studies directed at the determination of the reversible T▵S heating gave results that compared within 8% with theoretically derived values. Calculations based upon the 50-kWh MK II battery and a 10,000 miles driven/year show that by utilizing the thermal storage capacity of the system, essentially no additional energy is needed to keep the battery hot.
