Abstract

A battery module is provided. The battery module includes a plurality of battery cell assemblies having a plurality of heat exchangers therein. The battery module includes a first rubber cooling manifold configured to route a fluid into the plurality of heat exchangers. The first rubber cooling manifold has a first tubular member, a first inlet port, a first plurality of outlet ports, and first and second end caps. The first end cap is coupled to a first end of the first tubular member. The second end cap is coupled to a second end of the first tubular member. The first inlet port is disposed on a top portion of the first tubular member for routing the fluid into the first tubular member. The first plurality of outlet ports is disposed collinearly and longitudinally along an outer surface of the first tubular member and spaced apart from one another. The first plurality of outlet ports extend outwardly from the outer surface of the first tubular member. The first plurality of outlet ports route the fluid from the first tubular member into the plurality of heat exchangers for cooling the plurality of battery cell assemblies.

Claims

1. A battery module, comprising:

a plurality of battery cell assemblies having a plurality of heat exchangers therein; and

a first rubber cooling manifold configured to route a fluid into the plurality of heat exchangers, the first rubber cooling manifold having a first tubular member, a first inlet port, a first plurality of outlet ports, and first and second end caps, the first end cap being coupled to a first end of the first tubular member, the second end cap being coupled to a second end of the first tubular member, the first inlet port being disposed on a top portion of the first tubular member for routing the fluid into the first tubular member, the first plurality of outlet ports being disposed collinearly and longitudinally along an outer surface of the first tubular member and spaced apart from one another, the first plurality of outlet ports extending outwardly from the outer surface of the first tubular member, the first plurality of outlet ports routing the fluid from the first tubular member into the plurality of heat exchangers for cooling the plurality of battery cell assemblies.

2. The battery module of claim 1, wherein the first plurality of outlet ports are disposed below the first inlet port on the first tubular member.
