This study examines the implementation of a waste heat recovery system on an electric\nhybrid vehicle. The selected waste heat recovery method operates on organic Rankine cycle\nprinciples to target the overall fuel consumption improvement of the internal combustion engine\nelement of a hybrid powertrain. This study examines the operational principle of hybrid electric\nvehicles, in which the internal combustion engines operates with an electric powertrain layout\n(electric motors/generators and batteries) as an integral part of the powertrain architecture. A critical\nevaluation of the performance of the integrated powertrain is presented in this paper whereby vehicle\nperformance is presented through three different driving cycle tests, offering a clear assessment of\nhow this advanced powertrain configuration would benefit under several different, but relevant,\ndriving scenarios. The driving cycles tested highlighted areas where the driver could exploit the full\npotential of the hybrid powertrain operational modes in order to further reduce fuel consumption.
