HPWC at max power

Tried out burlington s.c. Sat. Worked as advertised,
210 miles from my house to s.c. We go down there often for long weekends now that sc open will use the tesla to go there.
Took wall charger I have in garage at my factory and ran 480v through step down transformer, I get right at 240v and 62 m per hour of charge,
Had my doubts about this car at first, not anymore
I often forget its electric.

Use a transformer that gives you 250 Volts on the secondary and you will get another couple of mph on the charge!

If you have 480V/200A 3-phase service, I'm guessing a one-bay, two-stall Supercharger in your employee parking lot would only cost $20-40k. Give Tesla a call!!!

Great to hear things are working so well. Have fun!

I had heard at one of the TESLIVE sessions that the onboard charger can actually handle up to 277V. I wouldn't want to experiment with that, but was wondering if anyone knew definitively if that is the case? It would be great to use 3-phase Wye directly.

The HPWC manual has explicit instructions on how to connect to US commercial 3 phase power and doesn't show any way to connect to 277V.

I'm pretty sure that superchargers need more than 480V connections - I seem to recall 12 kV, but maybe thats to feed 8 supercharger bays.

Each supercharger needs 480V "only".

Here is the label from a US supercharger:

Here is the label from a European supercharger:

The on-board charger in the Tesla is the same as in the Supercharger... There's just 9-12 of them stacked together in a SC vs 1 or 2 in a car. So if the SC can take 277v then so can the car. 3 phase 480v is 480v phase-phase and 277v phase-gnd.

Hmmmmmm ... interesting.

I'll bet this is why no Canadian supercharger sites yet. Our standard 3-phase distribution is at 600 VAC.

When I plug in a home I always see 250v. No problems.
