Abstract: A hot plate method and apparatus for the measurement of thermal conductivity combines the following capabilities: 1) measurements of very small specimens; 2) measurements of specimens with thermal conductivity on the same order of that as air; and, 3) the ability to use air as a reference material. Care is taken to ensure that the heat flow through the test specimen is essentially one-dimensional. No attempt is made to use heated guards to minimize the flow of heat from the hot plate to the surroundings. Results indicate that since large correction factors must be applied to account for guard imperfections when specimen dimensions are small, simply measuring and correcting for heat from the heater disc that does not flow into the specimen is preferable. The invention is a hot plate method capable of using air as a standard reference material for the steady-state measurement of the thermal conductivity of very small test samples having thermal conductivity on the order of air.

Abstract: A process of controlling the temperature of a battery pack includes the steps of determining the operating mode and present temperature of the battery pack. Optimal temperature for the battery pack depends on the operating mode and the difference between the present temperature and the previously identified optimal temperature. The battery pack is warmed if the temperature difference (measured minus optimal) is large. The optimal time interval over which the battery pack should be warmed is a function of the operating mode and the previously calculated temperature difference. A heater is switchably operated enabling and disabling the heat generating element to warm the pack to the previously identified optimal temperature.
