Charging the Roadster
- Thread starter malcolm

In most jurisdictions that is a requirement of the electrical code. The maximum permitted load is 80% of the rated load. Thus the 70A HPC requires a 90A circuit.
Problem is you cannot put a 60 amp breaker on a 50 amp rated recepticle, regardless of the wiring. NEMA 14-50 is only rated to 50 amps.
This is a North America thing. Breakers are rated for transient loads and continuous is 20% less. Over here in Europe kit is labelled for continuous load - so pulling say 32A from a 32A outlet on a 32A breaker is fine and indeed I have done it.
Didn't get that difference at all when I came out to the US in '01. Our company set up in a new office with an old building UPS. Rated at 100A I thought we had loads of spare capacity at 80A... middle of the night... click and it's dark and we're off the air.

How long do you have to be gone for it to be worth charging your Roadster in storage mode? I'm going on a long weekend trip (Wed-Sun kind of trip) at some point but wasn't sure if it was necessary to keep it in storage mode or not. Thanks.
Probably not necessary, but shouldn't hurt. I guess the main thing is what charge level you need when you return (since it may have dropped some). Would be nice if you could check and set that remotely.
I honestly wouldn't bother for a long weekend. When my Roadster is in storage mode, SOC drops by about 0.5% per day, or a little over a mile of range per day.
Caveat: this is during cold weather. If active cooling is required due to high heat, the SOC will probably drop much faster.

It's stated that charging in performance mode will charge the battery up to 100% and with higher voltage than normal.
So here is my theory: If you charge in performance mode to 100% and then drive only in range mode, you should at least get the same mileage as when charged in range mode. Is it possible you could get a handfull more miles with performance charging?

Before I leave my car I skip charging for the days before I leave so that the charge level is around 20% then put in storage mode. It's probably pointless for a few days but makes me feel better!

Well this makes our discussion about charging station locations obsolete...

Range and Performance charge to the same level. Range mode shows range based on the full battery, but performance doesn't include the bottom 10%.

Those are ok for now David, but will they make one with a J1772 conector?

I'm sure Tesla want to keep this advanced technology to themselves.
Of course, it's going to require a firmware update to enable charging while moving. Which version are they on now? 4.01?
