Hello danibjor - welcome!
I, too would like to share the electronics for the charger.
The patent you're referencing was ( I think ) first used by ACPropulsion, and may have been used on the GM EV-1.
One of the larger parts of a boost converter is the inductor, and the clever thing about this design is it actually uses the motor for that job.
I wonder - can this be done with a wye connected motor? Also, can this be done with a BLDC motor without causing the motor to move when plugged in?
