    FYI - A Model S HPWC is now installed at the Bellevue Square Tesla parking area. They replaced one of the two Roadster HPC's units with the HPWC. There is still one Roadster HPC available for Roadster charging at Bellevue Square.

    I charged on the HPWC yesterday at a rate of about 41 miles per hour (about 208 volts at around 70 amps - I have the twin on-board chargers).

    Nice. Now if only I could remember how to find the spot - Bellevue Square scares this country boy.

    Is that the typical rate for the HPWC? I thought it's supposed to deliver up to 60 miles per hour.

    But that is at 240 volts. Bellevue is 208 volts.

    Does the voltage make that big a difference? What difference in charging rate can be expected with 208v versus 240v?

    Yes. The power an outlet puts out is Volts * Amps, so a ~15% reduction in voltage reduces the charging rate by 15%. And note that the amps are lower here too - 70 instead of 80, another >10% drop. I would expect around 43mph at a 208V 70A station; and note that a lot of times the volts sag even lower than that. On my most recent road trip I saw anywhere from 41 to 44mph at similar stations.

    Would this explain why I'm not seeing a charging rate any higher than 21 miles per hour from my 14-50?

    Well, there's another issue where there seems to be problems with the mph display getting confused over what type of miles it is showing. Try changing it to display kWh instead to remove that factor.

    With a 14-50 you should be able to pull 40A at 240V (assume this is at home, rather than commercial) so that's 9.6kW. In an hour you should add 9.6kWh. Of course it may slow down at first as it heats or cools your battery. And it may slow down at the end if you do a range mode charge. If neither of those are happening and it's still slow, look at what the car says it is pulling for volts and amps.

    (Assuming ~3 miles per kWh, 9.6kW should give you about 29 miles per hour).

    I believe that the 60mph claim is for ideal miles added. I have a single charger and only get 24-26 rated mph on my 240V/40A NEMA 6-50 outlet. I have gotten 31mph when I switched the car to display ideal miles.

    Also, be aware that both the Washington Square and Bellevue Square spots have NEMA 14-50 outlets that can be used if the HPWC is being used.

    Was just there today. The HPWC charges at 72 amps @ 203 volts, around 44 MPH, 14KW. Had to try charging greater than 40 amps, cool. I was expecting some fans or something but completely silent. There was a HURD of Model S's there, maybe 5-6 in the Tesla parking area along with a pre-owned Roadster. Talked to a guy who just picked his up 3 days ago and has been charging up at home on only 120V. He has a HPWC in a box at home and has an appointment to have it installed next week. He said he only gained 30 miles overnight on 120V, not surprising. He needed the charge much worse than me so I moved and let him get on the HPWC. Apparently someone stole their HPC > Model S adapter, that sucks. Yes there is a 14-50 just down from the HPWC near the circuit panel. When I left there was another Model S plugged into the 14-50 as well. There are also 4-5 Chargepoint J1772 30A 208V stations just around the corner, they are $1.50/hour though. I'll update Recargo with the info about the HPWC, HPC, and 14-50.

    I copied this from brianman's post in another thread, but I also modified it:

    Exit 405 onto NE 8th westbound
    Left onto Bellevue Way (southbound)
    Right at the first driveway you can, after P.F. Chang's and Boom Noodle, but before Cheesecake Factory
    Right into the parking garage
    Sharp right (to the valet area) rather than going up the ramp
    Veer left of the island
    Sharp left into the Tesla parking/charging area

    Basically, it's in the parking garage on the ground level. Don't go up the ramp. If you circle around the ground level, you'll definitely see it.

    Thank you. It is now on a card in the glove compartment.

    You'll remember it pretty easily after your 2nd or 3rd trip.

    Probably so. But, I'll tell you, my first trip to the Tesla store was a real adventure. And the hike down to their parking area was another adventure. Not good with large multi-story malls.

    This, too, becomes easier with repetition. :)

    I asked the sales office about that yesterday. The white Tesla that's always plugged into the HPWC is being used for test drives. So you can't block it, park in its spot, or unplug it.

    Not that I mind - I think it's great for Tesla to have a car always available for a test drive, but this particular HPWC shouldn't be counted as a generally available charge station. (I'm sure they'll allow you to charge in a bind though.)

    I charged on the HPWC there as well. Got about 40 miles/hr. I'm still waiting for my HPWC to show up but I was wondering if anyone has gotten up to the 60 miles per hour that we've heard about. Once I noticed the rate, I asked the guy at the Tesla store how many amps theirs was connected to and he said 100. I also looked around the unit and found what appeared to be a 100 amp line. Maybe they just don't get that much power even though the lines can take it.

    This was discussed above. It's 72A at 203V (14.6kW), so 43mph is about what you should expect.

    At 80A on a 240V line, you'd get 19.2kW. That would be about 56mph. Maybe 60mph if you consider Ideal miles.

    Thanks Chad. I read the thread so I saw the previous discussion. I was mainly wondering if they actually have 100 amp service but only get 72 amps for some reason or if it really is just a 72 amp service. Guess I should've realized the guy in the store would be clueless.
