Abstract
A battery module or battery pack is provided having a serpentine counter flow cold plate with improved dissipation of heat from individual battery cells, wherein the cold plate provides a more uniform temperature gradient across the cold plate to more evenly transfer heat from the battery cells to liquid coolant circulating through the cold plate. The cold plate selectively omits turbulator material upstream of turbulators to control and govern the coolant fed into and through the turbulators to provide a more uniform temperature gradient across the cooling surfaces.
