Abstract

A system includes a battery module with a plurality of walls having a first end wall spaced apart from a second end wall. A plurality of battery cells disposed between the first end wall and the second end wall. The system also includes an inlet module pump communicating dielectric fluid into the battery module into a space between the battery cells and the walls. A compressible element is disposed adjacent to at least one of the plurality of battery cells and has an element wall and an element pump communicating dielectric fluid from the space into the compressible element. The system also includes a pressure sensor generating a pressure signal indicative of the pressure within the battery module. The system also includes a controller coupled to the inlet module pump and the element pump and the pressure sensor, said controller configured to control a pressure within the compressible element based on the pressure signal.
