TIL #RenaultZoe uses motor windings as the inductor of the buck-boost converter as they wanted to support 43kW AC charging without adding a 40kg inductor. DC charging has become the norm for rapid charging so this design has become suboptimal. Still it is an interesting creative #EngineeringDecision that will go down in history.
