Dodge all in on electric too 500 mile range Ram

Can someone explain to me the actual time in minutes or hours, whatever. How long is a 'fast charge'. Assume you have a three quarters batter discharge on a trip. How long does it take to recharge that battery.

People keep saying fast charge and quick charge which no definition in time.

Not to argue 'gas vs electric', just comparing time to fill tank vs time to charge when you are on a trip that's more miles than a battery will take you and you need a charge somewhere, wherever that exists.

500miles on an empty non-aerodynamic pickup is likely going to require more than double the long range tesla battery bank, so let's assume 250kwh battery bank.

A 30amp@120v RV outlet can put out on a continuous basis around 3kw, so it's going to be maxed out for around 83 hours (worst case scenario). If your RV it pulling an average of 1500w to run the air/con and other house loads, it could be upwards of a 160 hours.

A 50amp@240v, can put out around a little less than 10kw continuous, so about 25 hours but again house loads will increase that.

Of course, if you come in with the battery bank at 50%, it's less time but other than for short local trips, I would expect to see upwards of 80-90% of the battery used in a more typical scenario.

Dedicate fast charging stations can go much faster depending on the type and technology of the vehicle. Upwards of 200-250kw are possible on the fastest (so an hour or so) but it's hard on the battery packs to force feed them at such high rates. Usually, it's reserved for filling to 75-80% full.

Also, fast charging stations are quite expensive, as in 6 figure $$$$ per station expensive and out in rural areas it can be higher as half a dozen charging stations, may require a very large power feed. 6 - stations putting out 250kw each translates to a power feed capable of a continuous output of around 12,500amps.

A new park near a major high voltage power feed, it's expensive but doable. A remote park that struggles to get enough power for the fifty - 30amp sites it currently has not a chance they can make the numbers work to be installing high speed charging stations and 20-30% EVs expecting to charge off their existing grid will cause them major problems during peak periods.
