Well, the whole 'what to do with a trailer' while charging bit is an issue that needs addressing with all these electric trucks coming out.Too me EV's are useless for towing, unless it's short trips close to home. If I tow my boat to a lake it has to be less than 300 or less miles with no hills or it's not going to get there. And last time I looked after I parked my truck in the parking lot there was no place to plug it in. So, when I get off the lake at the end of the day how I'm I going to get home??
However, the flow for a 300 mile trip for a vehicle with that capacity is to charge once on your way there and once on your way home. Basically stopping around 200 miles in, charge and eat lunch, do your thing and turn around, make the same stop on the way home, and then plug it in when you park it in your driveway at the end of the day. This is where these high speed chargers come in handy. Cars like the Bolt only have a 55kw charger. It takes ages by comparison. Even worse on cars that dont have DC charging.
Im not trying to sell it to you as I can think of plenty of scenarios where this isn't ideal. Especially when going off the grid for other sporting activities. I'd say that if your travels take you along the major highways, it's not a big deal. You more or less stop for lunch 200 miles into your 300 mile drive, charge her back up, and make that same stop on your way home.
Personally, even though I'm looking at an EV for my daily commute and to drive to customer locations, i'll have to keep a gas vehicle around for areas where It just really isnt ideal. There were two 350kw chargers on my 300 mile drive today (I was explaining it to my boss earlier about the ev6 while we were trudging though a snowstorm). One half way, and one near the destination just by chance. But if we were heading northwest, I would have just had the one. There are a surprising number of charge point chargers around, but you really dont want to be charging these long range vehicles on those.
