Wireless charging is currently being researched as an alternative to plug in charging for electric vehicles. These systems are tested in concrete and asphalt highways. A current limitation in research is understanding how to manage the heat that these systems produce in the roadway.Prototyping wireless charging systems in concrete or asphalt is time intensive and expensive. An alternative way to test the thermal management of these systems is to prototype the systems in sand and use the results of sand experiments in combination with thermal simulation software to predict how systems will perform in concrete.My project consists of two parts.I have learned the ANSYS simulation software which is used to model the thermal effects of electronic components. I have validated those simulations with real world experiments.I have created a sandbox testbed for these wireless charging systems that will dramatically speed up the time it takes to prototype a system. This testbed uses a liquefaction process which allows a solid material to behave like a fluid. Using this process on a sandbox allows a wireless charging system to be inserted and removed from the testbed without having to shovel sand, dramatically decreasing the prototyping time.To finish this project, I will be validating thermal experiments in sand with ANSYS simulation software. This prototyping method will provide insight into what thermal modifications might be necessary for wireless charging systems to survive better in the roadway.
