Abstract
Methods and systems are provided for a battery cooling enclosure. In one embodiment, the battery cooling enclosure may be incorporated in an electric vehicle and may comprise battery cooling system, including a first support rail with a first coolant inlet, a second support rail with a first coolant outlet, and a plurality of cold plate slots arranged in parallel between the first support rail and the second support rail. Each slot of the plurality of cold plate slots is coupled to a first fluid passage of the first support rail and a second fluid passage of the second support rail. The battery cooling system of the battery cooling enclosure may thus allow for cooling of a battery using a variable amount of cold plates.
Claims20
A battery cooling system for an electric vehicle, comprising:
- a first support rail with a first coolant inlet;
- a second support rail with a first coolant outlet;
- and
- a plurality of cold plate openings arranged in parallel between the first support rail and the second support rail, wherein each opening of the plurality of cold plate openings is coupled to a first fluid passage of the first support rail and a second fluid passage of the second support rail.
A method for cooling an electric vehicle battery, comprising:
- flowing coolant into a first fluid passage of a battery cooling enclosure via an outer coolant inlet;
- flowing coolant from the first fluid passage into a plurality of inner cold plate slots arranged in parallel, wherein each slot accommodates one cold plate and each slot comprises one coolant inlet and one coolant outlet;
- flowing coolant out of the plurality of inner cold plate slots into a second fluid passage;
- and
- flowing coolant out of the battery cooling enclosure via an outer coolant outlet.
An electric vehicle, comprising:
- at least one electric machine coupled to at least one battery, the at least one battery positioned in a battery cooling enclosure, wherein the battery cooling enclosure is configured with at least one outer coolant inlet, at least one outer coolant outlet, and a plurality of inner cold plate slots arranged in parallel, each slot accommodating one cold plate, each slot comprising one coolant inlet and one coolant outlet.
