I'm curious, why did they choose 8320 cylindrical cells instead of a few dozen 60Ah prismatic cells? It seems the latter approach simplifies your battery monitoring/management scheme. |
You neglected to include that at 65 mph you would also be travelling a greater distance per unit of time.
If load increases 9 times, then your run time, not distance, is one-ninth.
The range is probably somewhere between 150-180 miles at 65 mph. The 1997 Solectria Sunrise using batteries with half the energy density could do better than that at such a speed.
James Worden, its designer, hypermiled it in the Tour De sol and got 373 miles(previous record), but that was not at a steady 25 mph and included some highway speeds.
