Vesc boost charging with external inductors

Hi, 
I am wondering if someone have tried to use boost charging through VESC but instead of motor to use external inductors?
Also at his github issue https://github.com/vedderb/vesc_tool/issues/141 , Benjamin told to disconnect middle phase wire, 
so current reading will reflect consumption from power source. Is this case we loose one  phase  winding, but how then boost converter is working ?
