The lightning fast charges up to 80% and then slowed down drastically. At a 350 kw electrify America charger, that means a charge rate of around 165-195 kwh for the first ten minutes, 150 kwh for a few minutes, 125 kwh to 80%, then 50+ kwh after that.
Another thing I'm not really seeing discussed is what people get for mileage in their vehicles. Over the last year, I averaged 1.7 mi/kwh. Most of my t miles are highway driving. If I lived in a suburb or city, that would jump to probably 2.5 or higher. I read a lot of people talk about Tesla's getting 3-4+ regularly. These values will greatly impact your cost and the amount of time spent driving on a longer trip.
My small suv is something like 4.3 city, 3.3 highway, 4.1 lifetime.
