In certain embodiments, a battery thermal management system includes at least one battery, at least one thermoelectric device in thermal communication with the at least one battery, and a conduit comprising an inlet configured to allow a working fluid to enter and flow into the conduit and into thermal communication with the at least one thermoelectric device. The conduit further comprises an outlet configured to allow the working fluid to exit and flow from the conduit and away from being in thermal communication with the at least one thermoelectric device. The battery thermal management system can further include a first flow control device which directs the working fluid through the inlet of the conduit and a second flow control device which directs the working fluid through the outlet of the conduit. The first flow control device and the second flow control device are each separately operable from one another.
