Wow. That is one way to make a simple math problem much too complex and with less accuracy.It's really exquisitly simple. Take the rated miles for your vehicle (314) and divide by 100 (3.14). That's the rated miles per percent of battery. Take the reciprocal of that (1/.314 = .32). Memorize that number (or write it on a sticky and put that in your truck). When at a charging station find out how many miles to the next one and multiply by that number e.g. 132 miles --> .3*132 + .02*132 =39.6 + 2.64 = 42%. That's how much charge you need to add. Note that in this case you can neglect the .02 and just rough it at .3*132 = 39.4 and then toss in a couple of extra percent. You would also toss in an extra couple of percent if you know the stretch or road you will be driving demands consumption a couple more percent that normal (because it's wet or there is a head wind or its uphill or you know this bit of road). Or just add 10% for "margin". Add 50% to your battery and go on your way.
I've posted this many times before elsewhere and often get responses such as "You call that simple?" I am aware that a frightening number of people are innumerate. This won't appeal to them.
Adding a 10% fudge factor plus a few percent here and there is a lot of wiggle room.
With my formula, we arrive at the next charger within a few miles of our target range every time.
