Battery thermal management system including thermoelectric assemblies in thermal communication with a battery
First Claim
1. A battery thermal management system comprising:
- at least one battery;
at least a first thermoelectric assembly and a second thermoelectric assembly in thermal communication with the at least one battery, the at least first and second thermoelectric assemblies each comprise thermoelectric devices, wherein the first thermoelectric assembly is in electrical communication with the second thermoelectric assembly;
wherein the first thermoelectric assembly comprises at least a first group of the thermoelectric devices and a second group of the thermoelectric devices, wherein the thermoelectric devices of the first group are in parallel electrical communication with one another and the thermoelectric devices of the second group are in parallel electrical communication with one another,wherein the second thermoelectric assembly comprises at least a third group of the thermoelectric devices and a fourth group of the thermoelectric devices, wherein the thermoelectric devices of the third group are in parallel electrical communication with one another and the thermoelectric devices of the fourth group are in parallel electrical communication with one another,wherein each of the thermoelectric devices comprise a plurality of thermoelectric elements; and
a circuit in electrical communication with the first thermoelectric assembly and the second thermoelectric assembly, the circuit configured to be selectively switchable to place the first thermoelectric assembly either in series electrical communication or parallel electrical communication with the second thermoelectric assembly in response to at least one parameter,wherein the at least one parameter comprises at least one temperature of a working fluid that flows into thermal communication with the at least one battery.

Abstract
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.
