Device for housing electrochemical cells
First Claim
1. A battery module comprising:
- a first end wall having a first end wall semi-enclosure and a first end plate, wherein the first end wall semi-enclosure and the first end plate align to form a first flow channel therebetween;
a first end wall manifold having a first inlet and a first outlet that are connected to, and in fluid communication with, the first flow channel such that a first fluid portion flows from the first inlet through the first flow channel and then through the first outlet;
a second end wall having a second end wall semi-enclosure and a second end plate, wherein the second end wall semi-enclosure and the second end plate form a second flow channel therebetween;
a second end wall manifold having a second inlet and a second outlet that are connected to, and in fluid communication with, the second flow channel such that a second fluid portion flows from the second inlet through the second flow channel and then through the second outlet; and
at least one stacking segment aligned between the first and second end walls, the at least one stacking segment including;
a dual sided segment with an external side configured, along with the first end wall, to define at least in part a first plurality of compartments when positioned in opposition to the first end wall; and
a semi-enclosure wall configured, along with the second end wall, to define at least in part a second plurality of compartments when positioned in opposition to the second end wall, whereinthe semi-enclosure wall and an internal side of the dual sided segment align to form at least one stacking segment flow channel therebetween, and wherein each of the at least one stacking segments further comprises;
a stacking segment manifold, the stacking segment manifold having an inlet and an outlet that are connected to, and in fluid communication with, the at least one stacking segment flow channel.

Abstract
Disclosed herein is a device for housing a plurality of electrochemical cells, wherein the housing provides stability, temperature control and maximum packing density. The battery module housing comprises a first semi-enclosure and a second semi-enclosure, wherein the first and second semi-enclosure are aligned to form compartments there between. Each compartment is designed to accommodate at least one electrochemical cell, such as a cylindrical battery or a prismatic battery. Each semi-enclosure comprises an interior wall and an exterior wall. The interior and exterior wall align together to form a flow path between the walls through which coolant or any other thermal management medium may flow. The coolant enters the semi-enclosure through a coolant inlet, flows between the interior and exterior walls; then flows out of the semi-enclosure through a coolant outlet.
