Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com - Maximizing average speed with an electric car

A while back there was a thread asking how fast you should go to maximize averege speed on a 1000 mile trip, I decided to try and solve a slightly simpler problem, i.e. Infinite trip, and charging stations everywhere:

Code:

#include <stdio.h>



int main(){



  double cdA  =       0.7;   // m2

  double crr  =       0.008;

  double mass =    1500;     // kg

  double para =     150;     // w

  double batCap=  44000;     // wh

  double chrgRte= 60000;     // w

  double timeLoss=    2;     // minutes

  double power, range, time, avg, vel;



  printf("#  speed     power   range    time     avg\n");



  for(int spd=10;spd<=250;spd+=5){

   vel=spd/3.6;

   power = para + vel*(0.5*1.225*vel*vel*cdA + crr*mass*9.81);

   range = vel*(batCap*3.6)/power;

   time = range/(vel*3.6);

   avg = range/(timeLoss/60+time+batCap/chrgRte);



   printf("%8.0i%10.2lf%8.2lf%8.2lf%8.2lf\n",spd,power,range,time,avg); 

  }

}

I was a bit surprised at how high your optimum speed is.
