“…Flywheels are more power and energy dense than are ultracapacitors; 22 this contributed to the fact that they were selected for the Porsche GT3R series of highperformance hybrid vehicles. 23,24 In order to hold adequate amounts of energy, flywheels must rotate very quickly, of the order of 60,000 r/min; this means that they must be machined very precisely and must use bearings of very high quality, which makes them expensive. 23 Furthermore, since their rotational speed varies with the square root of the energy stored in them, according to…”

The limitations of electrochemical batteries are one of the chief reasons that the widespread adoption of electric vehicles is slowing down. An alternative to overcome this is to use hybrid energy storage systems. One seldom explored alternative is the possibility of combining the electrical and hydraulic components of the battery in a powertrain intended for passenger vehicle use. The present research models an electrohydraulic hybrid vehicle and compares it with a baseline battery electric vehicle under an urban driving cycle. The results show a reduction in the energy consumption as well as a reduction in the battery current transients.
