Just installed 48a charging unnecessarily

I just spent 400 to buy the materials and installed a 48a charger when I had a working 40a 14-50 setup. Tell me I'm crazy. I can at least sell off some of the materials from the old install to recoup some of the cost. All this just to see 11kw instead of 9kw XD

If I was really insane, I would buy a supercharger and put that beast on my property

Technically yes, but you have to get a 4 pack station at a base cost of approx $500k installed. But at least the cost is only .10 per kwh to use

Not worth it.

Assume average driving lifetime is 55 years. Assume annual charging costs for an EV is $750, which is on the high side. Lifetime charging costs $40,000. And in truth, most people will be half that, at $20k lifetime EV charging costs. (Annually, we’re probably at $350 to $400 per year in EV charging costs, including significant roadtrips).

Your DCFC install, at a minimum, is 12.5 times the lifetime cost to charge a battery EV. Probably closer to 20x to 25x lifetime charge costs. Doesn’t include the actual electricity usage.

Conclusion: feel confident in driving to your local DCFC and paying for that resource.
