Abstract

An immersion cooling system (100) for immersion cooling of a plurality of battery cells of a battery (114) of an electric vehicle using a dielectric cooling liquid is disclosed. The immersion cooling system (100) comprising: a fluid circuit (102) configured for at least the circulation of the dielectric cooling to, and from, the battery (114), the fluid circuit (102) having a first branch (108a) and a second branch (108b), the first branch (108a) being parallel to the second branch (108b); a first pump (104) positioned along the first branch (108a); a second pump (106) and a valve (116) positioned along the second branch (108b), the second pump (106) being, relative to the first pump (104), a high-flow, low-pressure pump; an inlet sensor (124) position at or around an inlet of the battery (114); an outlet sensor (126) positioned at or around an outlet of the battery (114); at least one processor (130); and a memory device (132) coupled to the at least one processor (130), the memory device (132) including instructions that when executed by the at least one processor (130) cause one or more of the at least one processor (130) to: determine, using at least information from one or more of the inlet sensor (124) and the outlet sensor (126), whether at least one characteristic of the dielectric cooling liquid satisfies a threshold value; generate one or more signals, if the at least one characteristic of the dielectric cooling liquid does not satisfy the threshold value, to operate the immersion cooling system (100) in a pressure mode wherein the first pump (104), and not the second pump (106), pumps the dielectric cooling liquid and the valve (116) is at a closed position that prevents a flow of the dielectric cooling liquid through at least the valve (116); and generate one or more signals, if the at least one characteristic of the dielectric cooling liquid does satisfy the threshold value, to operate the immersion cooling system (100) in a flow mode wherein the second pump (106), and not the first pump (104), pumps the dielectric cooling liquid and the valve (116) is at an open position that allows a flow of the dielectric cooling liquid through at least the valve (116). Further, a method for operation of such an immersion cooling system (100) is disclosed.
