1. A battery module, comprising:
an array of battery cells; and
a cooling apparatus having a first line and a second line, each carrying a fluid flowing therein so as to each independently absorb heat from the cells of the battery module and transfer said heat to the fluid,
wherein the first line and the second line each extend perpendicular to the cells and parallel to one another across the array, an outlet of the first line is fluidically coupled to an inlet of the second line, and a flow direction of the fluid in the first line is opposite to a flow direction of the fluid in the second line, such that the cooling capacity of the fluid in the first line is greater than the cooling capacity of the fluid in the second line, and such that the cooling capacity of the fluid flowing through the first line and the second line is averaged.
