these have been around for a while in special applications.

they primarily use a standard electrical charge outlet for their
charging.  the engine is used to charge the batteries when needed or
in low level charge maintainer.
the serial hybrid is not really usable as a fuel saver like the
parallel systems.  the parallel systems use the normally wasted
kinetic energy to charge the batteries and are able to use the stored
charge to save on engine operations using fuel.  serial is always
using fuel unless an alternative charging system is available.

on the serial systems think of it as a battery powered car that
carries its own generator to recharge when needed.
