Abstract
A Lithium Ion battery cooling system for use in a hybrid vehicle comprises a plurality of self-contained liquid cooling modules, each cooling module including a closed and sealed container having an interior space. Each cooling module includes a battery assembly disposed within the interior space of the container and a plurality of battery cells having at least one fluid channel formed therebetween for receiving a fluid therein. A dielectric fluid is disposed within the at least one fluid channel. The dielectric fluid substantially immerses and is in contact with the battery assembly to heat and cool the battery assembly. A heating element is disposed within the interior space and heats the dielectric fluid. A cooling element is disposed within the interior space and cools the dielectric fluid.
