Charging specs updated in Blank Slate description.

[phidauex]

I never really looked at that picture very closely, but it looks like you can plug it into a 14-30, 14-50, or 14-60 by rotating the neutral lug into one of 3 different orientations. As @phidauex said, I'm not sure if it will actually draw 48A - it might only draw 24A, but it allows flexibility in other plug types. This is definitely on brand for Slate, allowing flexibility at a very low cost. The Tesla UMC will draw up to 32A and adjust current draw automatically, but you need to carry $60 adapters to do that. Slate does it at 24A, but with a switch to make it "free." You can put almost 12% back into the battery per hour at 24A (at 90% charging efficiency) and fill up from zero in just under 12 hours.

The rotating neutral plug is a pretty clever design. If the plug position tells the EVSE what maximum charge to use then it will be even cleverer still!

I seem to see 3 settings on the plug. Level one must be the position with 1 dot. It allows the main plug to plug into the 120v adapter. 2 dots looks like it might plug into my dryer outlet, although the lower prong is different. Maybe it plugs into 14-50 also. 3 dots might be 14-60.

If they are running new wires, ask about running the circuit as a 100A and putting a subpanel in the garage. Now new outlets are a 30 min job!

Subpanel job is pricey but Lord it creates an abundance of future options! I did this maneuver just 18 months ago at our Airbnb. Ended up balancing the loads significantly between the two panels and now have only Airbnb on that island with L2 EV charging. Have future slots for a pool pump, pool heater/chiller, etc. It wasn’t cheap but all done now.

This pictures makes clear that you need a D=D= (double socket) receptacle, but you don't get to plug anything else into it concurrently, because of the 2nd ground pin. Of course, you wouldn't want an extra load plugged in (and turned on) because the charger would want all the power available anyway.... But if you happen to have a single socket, dedicated receptacle, you can't use it! (Well, there are adapters that would push the receptacle away from the wall. Shhh!)

Looking at that double ground pin setup for the 120V plug, personally I would just dedicate the socket for charging and keep it plugged in all the time. I know it’s hard to tell from the picture, but to me it looks a bit fragile. And trust me, the plug and wire will get warm while charging. Over time the plastic casing will likely get brittle from heat, so leaving the setup undisturbed is good advice. Same goes for the 240V plug setup; expect even more heat on the plug and wire!

I seriously doubt the EVSE that comes with the truck will work for me. The nearest plug is too far away. I'm expecting I will have to get one of these: https://www.amazon.com/WenStorm-Vehicles-Overnight-16A-Rated-Continuous/dp/B0FXBGPYQ7

I'm glad to hear they will have a fix-a-flat accessory in the store. I'll probably do that rather than an actual spare.

My plan is to get a permanent charger installed, and I'd use that one for trips, for example at my sister's house, it was built with an outlet for EV charging, didn't get a good look at it, but it's highly likely I could just plug in.

My problem with that idea is I've probably had my last 3-4 flats(over multiple years) be sidewall damage where I would have been waiting on roadside assistance if I didn't have a spare.

A while back on his YouTube channel, The Ionic Guy was talking about https://modernspare.com/complete-spare-tire-kits/. Looks interesting; wondering if they'll make a kit for Slate.

I bought one for my X5 PHEV. It’s functional and takes half the space as a full size spare would. Mine came with its own jack and wrench kit.

My wife presumes it is a waste of space, but I’m not one to actually drive a run flat tire flat. You would ruin the tire and then voila, you are buying two tires so that the mate matches the tread of the new one.

With this little spare, you exchange the flat for the spare, and then REPAIR the flat, and go on with wearing the tires out evenly.

From the AMA on Reddit:
"... we will have a tire inflator and repair kit offered as an accessory in the marketplace."

I'm sure if ModernSpare wants to advertise on Slate's site, they would be happy to accommodate. But it's more likely that ModernSpare will just add the Slate to their list.

It's easy to change from a 20A, 12 gauge circuit with "undersized" NEMA 5-15R receptacles to a 20A circuit with NEMA 5-20R combo receptacles.

It is not easy to change from a 15A circuit to a 20A circuit.

Maybe. A lot of 15A circuits are wired with 12ga wire.

IF that's your situation you can upgrade the breaker and the outlet.

Code only calls for 14ga for 15A though ... so in older homes (and still possibly newer ones) you're probably looking at having 14ga wire and that's no bueno for upgrading to 20A.

Looks like Slate quietly updated the specs for the Blank Slate in the maker. The only meaningful specification changes I could find are the addition of Level 1 charging information and the revised Level 2 charging performance. Everything else looks like formatting or wording cleanup. changed:

Charging Updates

• Level 1 charging was added
  • 20–80% charge in approximately 17 hours
• Level 2 charging was updated
  • Increased from 25–32 miles of range per hour to 25–40 miles per hour
  • Full charge changed from 4–8 hours to 4 hours
• Level 3 chargingremains the same:
  • 20–80% in around 30 minutes

I contacted slate to find out what the level 3 max charging rate is gonna be and they said it's 120 kW

That's a little less than 2C which isn't all that great for a brand new EV. Model 3 RWD peaks at 2.81C. At least it's better than the Mach-E which tops out at 1.5C. I wonder what the average C-rate will be from 10-80%.

The average C-rate will be the most important thing. A 2C rate is fine if it holds it through much of the charging range. If it hits 120kW for 1 minute then rapidly folds back to 80kW then it is going to be a rough ride.
