U-formed cooling plate with solid fins for lithium pouch cells

A battery pack module, comprising:

• a cooling plate assembly having a first side wall and a second side wall spaced apart from one another and connected by a base wall, the first side wall, the second side wall and the base wall having at least one flow channel formed therein, the first side wall having an inlet in fluid communication with the flow channel, the second side wall having an outlet in fluid communication with the flow channel;
• and
• a plurality of battery cells disposed between the first side wall and the second side wall, wherein the cooling plate assembly is in heat transfer communication with the battery cells, and permits a coolant to flow into the inlet, through the flow channel, and out of the outlet, to thereby regulate a temperature of the battery cells.

A power system, comprising:

• a plurality of battery pack modules, each of the battery pack modules including a cooling plate assembly having a first side wall and a second side wall spaced apart from one another and connected by a base wall, the first side wall, the second side wall and the base wall having at least one flow channel formed therein, the first side wall having an inlet in fluid communication with the flow channel, the second side wall having an outlet in fluid communication with the flow channel, and a plurality of battery cells disposed between the first side wall and the second side wall, wherein the cooling plate assembly is in heat transfer communication with the battery cells, and permits a coolant to flow into the inlet, through the flow channel, and out of the outlet, to thereby regulate a temperature of the battery cells,
• wherein the inlets of each of the battery pack modules are in fluid communication with a same coolant inlet conduit, and the outlets of each of the battery pack modules are in fluid communication with a same coolant outlet conduit.
