Can you explain the weight law?
Wow, thanks for posting all the calculations.
Yes, thats exactly my thought. I actually have to use a Soliton 1.
If you convert a car to electric in Germany, the electric curb weight should be at most the same as the original ICE weight. Due to stability of the chassis.
I heard from someone from the TUV, its not a problem, if you are a few kg heavier. But the heavier you get, the more likely you have to do some stability tests.
Thats why I am looking for a donor with a 1.8l engine because curb weight is 1040kg. Does anyone know if the 1.8 Miatas were built without Power steering, too?
Same with the power. The electric power shouldn't be above the ICE power. If I install a K11alpha, and cut back the power at the controller I hope it should be cool.
I don't know, what they think, if I install 2 motors (even if two smaller ones).
two K9 220V would be an awesome setup, but it's still 20kg more than the K11alpha.
In the attached picture I did some calculations for acceleration.
I put in a weight of 1150kg. So 1060kg for the car and 90 for me
Didn't find the Area... so I put in 0,645 for Cd*A, but it doesn't make much difference anyway.
0,85 is efficiency of K11alpha. Won't be this efficient at high powers but still better then 100%
One question I asked me, when I saw the plot:
-How does Tesla get an acceleration of 3.9s out of 180kW. The Roadster definitely heavier then 1150kg...
