摘要： A method of manufacturing a solid-state battery module includes providing a housing, providing a solid-state battery cell stack, and pre-compressing the solid-state battery cell stack. The method further includes inserting, while pre-compressed, the solid-state battery cell stack into the housing, and releasing the pre-compression of the inserted pre-compressed solid-state battery cell stack such that the solid-state battery cell stack expands to establish a compression fit within the housing.

摘要： 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.

摘要： A battery module compression system includes a battery module having a first end wall spaced apart from a second end wall. Battery cells are disposed between the first and second end walls. A fluid path is between the plurality of battery cells and the walls. An inlet valve is in fluid communication with an inlet module pump communicating dielectric fluid into the battery module into the fluid path between the battery cells and the walls. A pressure sensor generates a pressure signal indicative of the pressure within the battery module. A temperature sensor generates a temperature signal indicative of the temperature within the battery module. A controller is coupled to the inlet module pump, the inlet valve and an outlet valve to independently control a flow rate into the battery module and the pressure within the battery module based on the temperature signal, and the pressure signal.
