The current it will pump up is the power you need to reach that speed. So for 100km/h you need around 8-9kW(I believe) ~110amps on 20smacribs wrote:@Allex.
I had no idea OVS was so insane. In fact speed increase from 70-100 km/h is a 42,9% improvement.
That is just off the charts. I was hoping OVS would yield at best 10-12 km/h or maybe even 15-20%. But you actually gets a 43% higher speed.
What current are the max-e pumping out increasing from 70 and up to max?
But here is a little catch. If OVS5 is what you need to reach 100km/h it will start to lower the current when you are close to that top speed.
So if you are using to much OVS, in our axamle 7, it will continue to push maximum current even at 100km/ because you tell the controller to go faster, but it cannot push you faster because it does not have more power - remember that effiency goes down at high OVS.
So it is essential to choose a suitable OVS value, otherwise it will just dump a lot of heat to the motor for nothing.
