Range Estimation:
Code:
range[km]=250 x capacity[kWh] / (mass[kg]^0.6)
-or-
range[miles]=250 x capacity[kWh] / (mass[lbs]^0.6)
Wire Temperature? :
Code:
Thot = Tcold + (K x ((Rhot - Rcold) / Rcold))
where K = 256.4 for copper
Thot = hot temperature in deg.C
Tcold = cold temperature in deg.C
Rhot = resistance at hot temperature in ohms
Rcold = resistance at cold temperature in ohms
Horsepower:
