This paper describes the bench testing procedures for a series-parallel, plug-in hybrid electric vehicle architecture used in its charge depleting mode. This architecture will be integrated into a 2016 Chevrolet Camaro by the Mississippi State University EcoCAR 3 Team. Our bench testing goals are to determine the accuracy of our current vehicle model components, if our current controller algorithms are efficient, and if our powertrain is properly integrated. Three torque control strategies using two UQM motors will be evaluated. Initial findings in this paper will be used to prepare the MSU EcoCAR 3 team for vehicle optimization and further integration work during the year three portion of the EcoCAR 3 competition. Three charge depleting motor control strategies are evaluated for drivetrain torque loss and energy consumption. The control strategies were tested using a Nissan Frontier chassis as the bench testing frame (or mule) on a chassis dynamometer.
