Sounds fascinating. You may be interested in Karen Pease's
EV charge calculator, and my own project to make
kinetic energy easier to visualize.
Of course, Karen's work is more towards a simulator, not a driving guide. You'd need to fill in all the specifics in Karen's simulator, of course. I don't know what assumptions it makes about throttle, but they're obviously different for an EV than an ICEV. A brake-specific horsepower graph for your vehicle's engine would help tremendously.
