In order to compete in the EcoCAR 2 competition, Embry-Riddle Aeronautical University has redesigned the Powertrain of a 2013 Chevrolet Malibu into a plug-in hybrid electric vehicle. This endeavor was made possible by the EcoCAR 2 competition sponsored by the Department of Energy, General Motors, and Argonne National Laboratory. The Powertrain was changed from a conventional internal combustion engine with a start/stop capability, to a fully electric Powertrain, with a diesel generator, and plug in charging capability. This paper will cover the electrical work performed on the vehicle during the summer prior to year three of the competition, EcoCAR 2 year three, and preliminary work for EcoCAR 3 year one competition. The main focus of this paper will be on the electrical system integration and vehicle testing. Some of the systems include for the EcoCAR 2 are the Selective Catalytic Reduction system, high voltage cabling optimization, CAN bus network, and charging system. For EcoCAR 3, the design and build of a high voltage distribution box, for bench testing, will be discussed. Simulations of the high voltage bus are also explored to gain insight into the voltage ripple and resonant frequency of the high voltage system in the vehicle
