The project is emphasized on the thermal management of Electric vehicle relevant to the ultra fast charging in a static state. The charging power is 100KW, and the loss energy in the process converted into heat. A cooling system is required to dissipate the heat produced during the charging process. In the project, the thermal model is established, also several simulations is mandatory to make the conclusion. The process involved the design the 3D model and drawing, simulation of the designed model and intergraded with the vehicle cooling system. Software Solidworks and SimulationX are specially utilized for the purpose. The Solidworks is responsible for drawing the model and simulating the cooling process.
