Performance Investigation of a Series-Parallel Petrol-Electric Vehicle

The energy savings potential of a 1325kg series-parallel petrol-electric vehicle was evaluated using simulated high way fuel economy test (HWFET) and urban dynamometer driving schedule (UDDS) drive cycle data. Analysis showed that, the average percentage reduction in fuel compared to the most efficient conventional car is approximately 60% combining both cycles. This paper also shows that, the regenerative braking system recovers at least 1% of the energy loss associated with the internal combustion engine in every 1.789km distance of the UDDS drive cycle and 3.756km in the highway drive cycle when compared to the conventional braking system.
