1. A battery thermal management system comprising:
- an inner housing containing a plurality of battery cells;
an outer housing enclosing the inner housing;
a fluid channel defined between the inner housing and the outer housing; and
a fluid circulator in fluid flow communication with the fluid channel to selectively circulate one of a first thermal fluid and a second thermal fluid through the fluid channel,wherein the first fluid has a higher thermal conductivity than the second fluid.

Abstract
A battery thermal management system includes an inner housing containing a plurality of battery cells, and an outer housing enclosing the inner housing. A fluid channel is defined between an exterior surface of the inner housing and an interior surface of outer housing. The thermal management system also includes a fluid circulator in fluid flow communication with the fluid channel to selectively circulate one of a first thermal fluid and a second thermal fluid through the fluid channel.
