Niels … this is not only a fantastic simulation .. but also a great explanation of the rationale for the development of each element of the hybrid drive. I never really understood why the planetary gearset was really required. Also I like how you have shown that an electric motor can serve as a clutch in an ideal world. Having watched this video I can see other applications such as diesel electric trains and ships where a planet gear could be employed to improve efficiency. Also do you know the efficiency of power transfer from ICE -> wheels .. versus ICE -> MG1 -> Inverter -> MG2 -> Wheels ? Well done.
