usage = '''
usage: %s rechargeTime totalMilage

recharge time should be hours, can include fraction of hours

assumptions: you start with full SOC, travel at constant speed until empty,
             and fully recharge. Assumes you the following data points:
               mph   range
               ---   -----
                40    145
                55    100
                70     80
I used this calculator: http://www.mathcelebrity.com/3ptquad.php
to fit a curve to the three points to estimate ranges for other speeds
