Default Formulas

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:
Code:
Hp=(torque*RPM)/5252
AWG to Metric Conversion
