1 MW EV CHARGER

The objective of the project is to design and build a fast, high-capacity Electric Vehicle charging device that employs passive convection cooling only. The project will conclude with a demonstration of an electric vehicle charger that takes 480VAC line-to-line rms three phase input at 1200A rms per phase and produces a DC output capable of 1000A at a voltage of 1000V. The rated output power of the electric vehicle charger will be 1MW for a continuous runtime of ≥168 hours with a duty cycle of 120 seconds at peak power with 20 second no load period. The proposed efficiency of the converter will be peak at 98% and ≥95% at 5% load with a power density of 450W/in3 and a specific power of 11kW/kg.
