Method for air cooling of an electric vehicle traction battery with flow shifting
First Claim
1. A thermal management system for a battery, said battery including a plurality of battery cells provided in an enclosure, said enclosure including a first manifold having a first end and a second end and a second manifold opposite to the first manifold having a first end and a second end, said system comprising:
- a first three-way valve for allowing fluid flow into or out of the first end or the second end of the first manifold; and
a second three-way valve for allowing fluid flow into or out of the first end or the second end of the second manifold so that the fluid flow through the enclosure flow shifts in a back and forth direction.

Abstract
A thermal management system that provides air cooling and heating for a battery by flow-shifting air through a battery enclosure. The battery includes a plurality of battery cells provided in the enclosure. The enclosure includes a first manifold having a first end and second end and second manifold opposite to the first manifold having a first end and second end. The thermal management system includes a plurality of valves for allowing air flow into and out of the first end or the second end of the first manifold and a second valve for allowing air flow into and out of the first end or the second end of the second manifold to provide the flow-shifting.

12. A thermal management system for a battery, said battery including a plurality of battery cells provided in an enclosure, said enclosure including a first manifold having a first end and second end and a second manifold opposite the first manifold having a first end and a second end, said system comprising:
-
a blower providing an air flow to the enclosure; and a plurality of valves directing the air flow from the blower through the enclosure, said valves being selectively controlled to provide air flow-shifting through the enclosure so that the air flow alternates in direction through the enclosure, where the plurality of valves is four valves. - View Dependent Claims (13, 14, 15, 16)

17. A thermal management system for a battery provided in a battery enclosure, said enclosure including a first manifold having a first end and second end and a second manifold opposite the first manifold having a first end and a second end, said system comprising:
-
a blower providing an air flow to the enclosure; and a plurality of valves directing the air flow from the blower through the enclosure, said valves being selectively controlled to provide air flow-shifting through the enclosure so that the air flow alternates in direction through the enclosure, where the plurality of valves is six valves, and the valves can be configured to direct the air flow into either the first or second end of the first manifold and out of either the first or second end of the second manifold, and alternately configured to direct the air flow into either the first or second end of the second manifold and out of either the first or second end of the first manifold.
