They say the level two charger drops that to just 2.5 hours. Makes me think the factory box is just pretty amp limited. It says 12 amps 1440 watts that's at 120. So if i tried to use the factory box but with a 240 adaptor would it just run the same 12 amps but then 2880 watts? That means an actual 240 charger running the full 27.5 amps is needed to do the 6600 watts.

OK, I know you guys probably get this I'm just working it out in my head.

anyway even at 1440 watts a 16,000 watt battery should fully charge in 11.1 hours but I'm sure it ramps down a couple times as it approaches 100%

I bet the 2.5 hrs at 6.6 is a bit optimistic as well, probably more like 3 to hit 100%.

Also isn't 100% charging bad? I can't seem to set other limits. Maybe what they call 100% isn't actually 100%.

Your assumptions are correct.

Note that preheating a plug-in (or EV) usually draws more than the 120v outlet can keep up with, so it will use a little bit of the battery in the process. Generally you need to step up to L2 if you want to avoid any battery drain during preheating.

You could install a 30 amp receptacle and buy an adapter to use with your stock EVSE. The stock EVSE will limit itself to 12 amps, so no risk of overloading a 30 amp circuit. You'll be limited to ~2.9 kW though instead of the full 6.6 the van is capable of. The other sucky thing is that RV hookups tend to only have NEMA 14-50 receptacles for their 240v service, so your adaptor wouldn't work there.

Alternatively you could buy an EVSE and have it hardwired to your existing 40 amp electrical run.

If it were me though... and this goes against code and would blow up 120v appliances if you connected them... I would simply wire a NEMA 5-20 receptacle to the 240v circuit and plug your EVSE into it. I'd put a red warning sign on it that says not to use the outlet because it's 240v. I'd have a fire extinguisher rated to put out electrical fires nearby in case someone still decides to disconnect your EVSE, not pay attention to the warning sign, and plug in a 120v appliance. I'd do this because it's electrically safe so long as nobody ever tries to plug a 120v device into it, and it's the cheapest since the only expense is a receptacle.

NEMA 5-20 on Amazon

Your probably the kind of guy who makes their own deadman parallel cords. LOL.

I think I'll just put in a 30 amp 240, buy the adaptor, and run the 12 amps knowing 6 hours charge is going to be fine. I'm sure I can use the 30 amp 240 for other things as well, like our camper. Even after driving back out to the dealer after work, and then home, a total of 17 miles all EV overall today, it went from 91% to 35% and shows 8 hours to recharge on the 120. That dealer is way outside of town by the airport so that's beyond any normal daily usage. Getting that 8 hours down to 4 would be pretty good. Even 12 hours isn't a deal breaker as we are normally done and home by 6pm most days, maybe 10pm once a week, and then out again no sooner than 6 am.

If anything I may want a 2nd charger so I can do 2 spots to charge as we have a split driveway and my wife prefers to park in front of the house, not in the garage. Maybe use the factory 120 up by the front door and get a 20 amp or so 240 charger for the garage if we need to turn and burn sooner.

I did remote "start" it this morning but not for very long, just as I approached it and then watched it for a minute or two to see how it acted. It did seem to be keeping up but the garage was still probably 50 degrees, not the 32 it was outside, and I didn't turn on the heated seat and steering wheel until I got in. If I remember right it was saying 5 kW was being used by the climate when I was driving to work. That would mean the 1.4 kW obviously doesn't keep up. I don't know how much the AC draws as I shut down the climate control as it was a perfect 61 this afternoon.

All this is probably academic as if my wife ends up being the primary driver on this, she will just use it like a regular minivan. She already calls it my "space" car and can't figure out why it doesn't start when you push the button. At least she says "my" meaning me, maybe she plans to keep using the old van.

We're coming into the most efficient part of the year to drive EV. Don't be shocked if your winter range is 2/3 of your summer range.

I just cancelled my hitch order. I saw in the manual where it still says towing not allowed with hybrid even though Mopar sells a hitch that fits. Apparently it's just for bike carriers and such. I think a small trailer in the wake would be no different than loading it up with 7 people but I'm not willing to blow warranty coverage just yet.

It also looks like kind of a PITA to install the factory one, and the aftermarket ones hang down pretty low.

Oh well, I still have different tow vehicles, Just my dream of getting 25 mpg or better with the teardrop is smashed for now.

What could be a reasonable motivation for the hybrid not featuring a towing capability?

Would I just get the one listed Canada 15' cord even though I'm not in Canada? The 15" should be good for me, the 240 outlet is right in the middle of the wall on the side the van charges on, even a 7 foot cord would be plenty. It shows free shipping and no tax so $249 is really good for a 30A.

Is that hardwired? I can't see much info on their page about it.

When the clearance started there were 30 different versions both corded and hardwired.

What is left, is whatever is left, Iím told the plug in version comes with an obscure obsolete plug nobody uses anyway
