Steve, The 300A at 300V when cruising 50 MPH is consistent with the 15kW that I found as a minimum for my light truck cruising, multiplied by 6 (the ratio between the ICE versions MPG rating) so a minimum cruising power of 90kW and a more real-world usage of 150 to 200kW on the freeway doing 65mph for 3 hours comes down to the same numbers that we saw earlier, between 500 - 600kWh for 200 miles range.
Thanks for that data!

My part of this project was to try to make what the customer though was the way to do this, work. He picked a 2,600 lb 300hp sepex motor , because it weighed as much as the diesel engine . We started and ended with a 2k zilla hooked to the armature and a bank of relays and resistors to controller the field ( field rated at 300v 6 amp ) . Things seemed to be working pretty well until the Zilla erred he decided to switch to a contactor controller using heating elements and contactors . He felt 3 speeds would be enough and I tried to explain the move steps we had the less violent the change in speed would be between each step , but what did I know. First ride with this set up was quite entertaining nothing broke but the shift from medium to hi was specular . Next came a 7 step set with 40 or so hot water 2400 w heating elements in series ,parallel , all inside pipe with water . test run looked like a steam engine simi . It was some what more controllable but not really real world drivable. so , back to the zilla It was hard to get real numbers as to power used with all the monkey play going on , I seem to remember 50 mph pulling 300 amps at 300v while cruising . The info in on one of the videos , . I would have liked to have used 2 net gain 11" seems like they would handled the 300 amps .
