  • Patent number: 11984572
    Abstract: A battery cooling system includes several battery cooling plates connected to a coolant manifold and coolant chiller. The coolant chiller is configured to remove heat from a flow of coolant that circulates through the battery cooling system. The coolant manifold has a first and a second chamber that both extend in a longitudinal direction and that are spaced apart and separated by an air gap. The first chamber receives a flow of chilled coolant from the coolant chiller, and the second chamber delivers to the coolant chiller a flow of coolant to be chilled. Plastic connectors in one-to-one correspondence with the battery cooling plates are mounted to the coolant manifold to fluidly couple the first and second chambers of the coolant manifold to the battery cooling plates.
