Yes but sigmadrives go only upto 96V (or special 120V upto 144 Volt soon).
The above mentioned controller are all designed to work on high voltage above 200Volt (but will also work on lower voltage)!
No, see: http://www.dmcde.de/pdf/sigma2.pdf 120 & 144 Volt available on request!
40KW (450 apms) that is PEAK- only for a few seconds, not really helpful for German Autobahn . You have to compare the continous amps (1 hour)- usaually just about half of this: sigmadrive act950l = 240A!
there is another but: normal ev needs ~16kW to maintain speed of 100-120km/h, another 16kW to accelerate to that speed. So concluding this theory, 40kW peak for 15seconds will make ev going 100-120km/h
I do not really know what U have in mind.. on DE autoban I travell with speeds 100-220km/h with diesel ICE.
My vision for EV is that it belongs to city traffic only.
Please change that quote from literature, it is theoretical. Manmy people here could misunderstand its meaning. (erase voltages, it is better to write HI and LO)
Just got a quote from Piktronik for their controllers:
sac60 is at Eur 3.850,- +Vat (developed to suit perm pms 156w)
sac41 is at Eur 3.750,- +Vat
