The Serial Hybrid Drive

The Serial Hybrid Drive







A similar version of this drive variant has been used for years in drives on electric diesel locomotives and ships, for example. There is no connection between the combustion engine and the wheel and so the E-machine powers the vehicle. The combustion motor can always be operated in the best operating range and generates mechanical energy for the generator. Power is supplied to the electric motor either directly from the generator or from the high-voltage battery. If the capacity of the high-voltage battery is too low, the combustion engine starts and charges the high-voltage battery via the generator.
