Using 110v would take forever (all this stuff I’m getting from my dad and guys in the house) - you need at least 220 min. Still in all, how long would it take to amortize an EV over gas driven car?

Well, not literally forever, the universe may stop expanding, then collapse. But the calculation is pretty simple. Any outlet will give you 15 amps You should have one that will give you 20. But 110 times 15 is 1650 Watts per hour. A Tesla has 75 or 80 kWh capacity, call it 85,000 Wh to allow for charging losses. That's 85,000 / 1650 or 51 hours max for a maximum charge.

Amortizing the cost is tricky. If you drive a lot of miles and run down the battery a lot the EV's battery will depreciate. Anything close to full discharge can be done 1000 times with a normal lithium battery. Maybe EV batteries are better, I don't know. But if you don't drive a lot of miles then you won't use a lot of gas anyway.

In my case I drive 45k miles a year, although I'm trying to lower that. That's 1300 gallons of gas a year or $5600 at the Brandon peak price. The electricity for an EV would cost me $1800 a year. With that many miles I would be using up the lifecycles of the battery. But with the savings it would take about 5 years to pay for the extra $20k I would pay for the vehicle.

So with gas getting cheaper once we get rid of Brandon, and if I can drive fewer miles, it won't make much sense for me to buy one.
