So, boost inductors of low inductance value like large currents to stay out of discontinuous mode. And a boost isn't technically needed for a v/hz below battery voltage, but I don't know how hard that makes the inverter controllers job having multiple bus voltages. But a smaller value inductor for a given current carrying capacity will mean less losses.
For most of my driving, I pulse and glide, so an all-or-nothing booster would be quite manageable, but with a cpu it could do that on a much smaller scale, i.e. run the booster %10 of the time, or 10/100 of a second or more depending on demand to optimize the inductor to the smallest "continuous boost mode" size. Is that sort of what you are thinking CTS? I would like to see it rated for continuous duty cycle though, direct drive vehicles will need boost for sustained high speed.
