1. A battery assembly comprising:
a plurality of battery cells arranged in a first cell row and a second cell row;
a battery housing storing therein the battery cells and including inlet and outlet fluid ports configured to respectively receive and evacuate therethrough a coolant fluid; and
first and second separator plates located between the first and second cell rows and each defining therein multiple coolant channels arranged in adjacent channel bands, the first and second separator plates being in face-to-face contact with each other such that each of the channel bands of the first separator plate is aligned with one or more of the channel bands of the second separator plate to cooperatively distribute the coolant fluid onto and vertically upward between the battery cells.
