Just how much do you think you will save over the 3 years with this EA promo? I think this is marginal, if anything relative to the price of the vehicle. I just charge at my house at night, I will most definitely not go out of my way to try to get a free charge at EA. It might save you a few bucks on the occasional road trip but it's more of a marketing gimmick than true value for anyone. I expect that in 3 years I will probably save less than $500 in charging fees total, if that. If you told me I could trade the $500 for a guaranteed working no-wait 350kW charger on any road trip I'd gladly take that over some BS free charging gimmick.
BTW, the EA contract specifically states no ride-share use is allowed but then again who would want to Uber with a $100k+ car unless it's to show it off and for the novelty of it.
EA charging is especially beneficial to cross-country driving and to owners without home charging, e.g. owners in apartments/homes without EV charging capability.
How much you can save, though, depends on the cost of the service. For example, here in Alabama you are charged by the connect time, usually 32 cents per minute. Due to the 800-volt battery, I can charge in about 20 minutes (at 200+ kW rate), so it would be about $6.40.
In Florida, though, it’s 43 cents per kWh, so 54 kWh would cost $23.22. Huge difference, but still less than gas for ICE, especially at current record prices.
I do most of my charging at home for about $0.108 per kWh (off-peak discount of 20% on $0.13 per kWh base rate) for a cost of $5.82 for 54 kWh.
Owners with solar power pay nothing additional for home charging.
On the road, free charging is available at many hotels, either J-1772 or Tesla with one-time cost of Tesla-to-J-1772 adapter. These are slower, but you’re spending the night, so you’re fully charged in the morning for free. Unless, of course, some inconsiderate ICE driver blocks the charger.
