Composite graphene-aluminum battery pack cooling plates

A battery pack assembly, comprising:

• a battery pack enclosure including a floor and a plurality of side walls;
• a first cooling plate supported by the floor within the battery pack enclosure, wherein the first cooling plate is formed of graphene aluminum composite, and wherein the first cooling plate includes:
• a first planar wall and a second planar wall;
• a first coolant inlet port and a first coolant outlet port disposed along an edge of the first planar wall and the second planar wall;
• a first coolant volume defined by the first planar wall and the second planar wall;
• and
• at least one first coolant flow path defined by and extending through the first coolant volume between the first coolant inlet port and the first coolant outlet port;
• a plurality of battery cells supported by the first cooling plate, wherein the first cooling plate is disposed between the floor of the battery pack enclosure and the plurality of battery cells;
• and
• a plurality of second cooling plates, wherein each one of the plurality of second cooling plates is disposed between each of the plurality of battery cells, wherein each of the plurality of second cooling plates is formed from graphene aluminum composite, and wherein each of the plurality of second cooling plates includes:
• a third planar wall and a fourth planar wall;
• a second coolant inlet port and a second coolant outlet port disposed along an edge of the third planar wall and the fourth planar wall;
• a second coolant volume defined by the third planar wall and the fourth planar wall;
• and
• at least one second coolant flow path extending through the second coolant volume between the second coolant inlet port and the second coolant outlet port.
