    Has anyone heard anything about this? I'm supposed to be going over to silverwood in July for four days with my mom and 2 kids and if it was just me and hubby and kids I would do this trip with my girl in a heartbeat but my mom is already skeptical of the tesla (it took me you have no idea how many hours assuring her I could make it from issaquah to ellensburg supercharger and then from there to her house in mattawa) which I did and both stops I had like 175 miles at ellensburg and them getting to her place 220 miles left but she refused to go into tri cities and come back...."range anxiety" she drives a Merc and I don't want to have to fork over $ for gas when I could drive my girl over plus the tesla is more comfortable than her Merc

    anyone over on that side with any updates would be greatly appreciated!

    No news on the Coeur D'Alene charger yet, but Ritzville to Silverwood is ~120 miles one way. Only 110 miles if you pick the right path.
    They do have parking for RVs in Silverwood, but I don't know if they have NEMA 14-50 hookups. If you're going to be there for 4 days, 110V would be sufficient to make it easy to get back to Ritzville.

    According to the website, the Silverwood RV Park only has 30 amp power. Even with the right adaptor, charging will be slow.

    30 A (24 if a NEMA 10-30) is plenty. You would likely spend at least 6 hours at Silverwood, which would give back 108 miles range.

    30A RV outlets in North America are only 120 V, which is slow: 24A*120V= 2.8 kW or about 8 mph. Also, I am not sure if the Model S can charge at the full 24A when only 120 volts are available, maybe the dual charger cars can.

    Should be fine. A single charger can handle 10 kW (40A on both 120V legs of a NEMA 14-50: 40A*120=4.8kW, 4.8*2=9.6kW), so 24A across one 120V leg should be no problem.

    According to a Plugshare contributor "Sue" the GM of the Springhill Suites in Coeur d'Alene stated they were "in the running" for the CDA supercharger site.
    SpringHill Suites | CDA, ID | Electric Car Charging Station | PlugShare

    I wasn't able to find any electrical permits for that location yet though.

    They already host a J1772 charger - this would be an additional option for the OP - but shouldn't be needed given the distance to the Ritzville SC.

    One needs to build a special adapter for this, and then, at least when I did it last, my dual-charger-equipped car would only charge at 20A.

    Just did another search for permits in and around Coeur d'Alene. I could not find anything relevant. Sigh!

    You can buy an adapter: NEMA 14-50R to TT-30P RV Plug Adapter. I know this one works. One user reported that he sucessfully set his car to charge at 24A using this adapter. Because the car sees the NEMA 14-50 adapter that this adapter plugs into, I believe you could set the charge rate higher than 24A, but you should not exceed 80% of the adapter's 30A capability.

    I don't think it's the adapter the car is looking at but rather the voltage. That's why I'm surprised that someone got 24A. Can you supply more info on this?

    I think it is both, actually. The car see the 14-50 adapter, but only one leg, so it allows 1/2 of the usual 40A, which is 20A.

    Take a look at the review on the page I linked: NEMA 14-50R to TT-30P RV Plug Adapter

    Here is the review, which you can see is quite recent:

    Worked fine for me. I had no 20 amp limitation from my Tesla S. Set to 24 amps, I get a solid 14 km/h charge rate (8,75 miles/hours). http://mon.pq.org/depot/monpq_534f1f95de45d.jpg

    Not sure those numbers make sense. maybe 110V * 24A wished he had posted current and voltage. still a little skeptical of that review.

    The numbers make sense to me.

    120V * 24A = 2.88 kW

    My NEMA 14-50 gives me 240V * 40A = 9.6 kW, a rate that is 3.33 times as fast.

    3.33 * 8.75 miles/hour = 30 miles/hour, which is the rate I get with my NEMA 14-50.

    I own this adapter and have used it, but not with a TT-30 outlet. I adapted it back down for use with a NEMA 5-20 outlet, and had no problem dialing the car's charge rate up to 16A. So I cannot say from personal experience whether the car would allow me to set the rate up to 24A when connected to a 30A outlet, but I can verify that I was not limited to 12A. I have no reason to doubt the review. Did you look at the picture he posted? It shows 8 mi/hour charging at 24A.

    are you all really going to go over the whole 24 amp 120v discussion here too? Why not just read It IS possible to charge at 24A from a 120V TT-30 plug... which has covered every possible angle with screenshots and everything.

    If you are too lazy to read the whole thread the cliff notes summary is, yes you really can do it but some Model S cars are limited to 20a on 12v and some aren't. If your car plays nice with it and you don't kill anyone or burn anything down you can get more than 20a on 120v.

    Mods may want to snip out OT posts to the relevant thread.

    Andy,

    Can you give the nature of your source? There have been no new permits that could be anywhere near Springhill Suites. i.e., nothing on Seltice and nothing on 22nd or 23rd. I may head over to Coeur d'Alene this coming weekend and ask around.
