Supercharger Stations

With the recent power outages due to Hurricane Sandy, how will the Super Charging stations operate in the event of the power grid being down? Reason I ask is that for the Supercharging Stations to feed the power grid with the excess solar energy, they will have to be a Grid-Tie system.

All Grid-tie Solar systems shut down when the grid is down. This is per code: National Electric code requires that when grid is down, solar cannot operate. Your inverter piggybacks off the sine wave from the grid. When there is no sign wave present, inverter will not operate. The only way to reap the solar electric when the grid is down is to store the electric in batteries, have those batteries tied to a separate dedicated panel for emergency loads and then it could operate independently of the grid.

Given that the Super Charging stations may have battery backup, what happens after a few days with the grid being down? No more juice.

To me, the National Code cripples a Solar panel system. Why can't there just be an automatic transfer switch that still feeds solar power to the local house or charging station and not backfeed the grid in the event of the grid being down. I am curious as to the purpose of this National Code and wondering if Tesla and/or Solar City is looking into a solution for this.

I have a home Solar system and it makes me crazy to see my system down during power outages.

jerry3,

I'm assuming that the Model S will be revolutionary, and that other makers, particularly of premium cars, will soon want to introduce long range BEVs. Licensing the power train and battery technology could be a moneymaker for TM, and would certainly be consistent with Elon's long-term goal of promoting the adoption of EVs generally.

DouglasR;
Seems unlikely to happen just that way; the form factors others use is so different, especially large custom cell sizing, they would have to redesign from the ground up. Expense is also an issue; TM has squeezed and vertically integrated everything possible to allow more "room" for battery costs. Hard for others to make the same "room".

And union involvement/opposition/featherbedding is sufficient to keep brick walls in front of much serious range expansion.

I think TM's 100-300% range margin is likely to hold even after much larger cap batteries are developed. They might permit other makers to reach TM's current levels, though. Someday.

"And union involvement...."

I don't understand these idiotic comments. Unions have nothing to do with the development of BEVs. Toyota does not use union workers and they still can not create a longer distance battery setup. Your comment is just the usual endless drivel coming out of an anti-union persons mouth. If your rhetoric was true China would already have 500+ mile BEVs.

I would also say that unions are not relevant to the technology.

Regarding supercharging on the 40, if it was possible (its not), you would have to charge slowly, and you're in the ac charger speed range now.

@Teoatawki
have you tried using Recargo or Chargepoint app or web site to find the chargers? I checked Minneapolis, and it doesn't seem like any hotels there have chargers!

I didn't find any hotels with chargers either, but it looks like there's a Marriott Residence and a Walgreens with a charger right around the corner. Judging by the other businesses around (McCormick & Schmick, Barnes & Noble) I'm guessing it's a nice area so might be a good option.

Google Maps comes in handy searching for chargers at/near hotels. If you do a search for hotels at your destination city, then a search for ev chargers, you can turn on both results at the top right of the map and see where they're close to each other (or coincident).

Brian H,

I'm not predicting that TM will license its technology; I'm hoping it will. TM will not be able to put superchargers everywhere they are needed. However, EVs will not make a significant dent in the automobile market until quick charging is nearly as ubiquitous as gas stations.

Yeah, I don't think TM is reluctant. I don't think the majors and others are flexible enough to accommodate it. Even Toyota just sort of went half-vast. The upcoming MB product will be very interesting!

Found the Sc station at Gilroy Outlets.Two stations near/behind the Sony store. Adjacent to the other charge stations. One Leaf was charging. No MS but some youngsters spotted my Tesla hat and with great delight told me that they often see MS charging there.Then they went on about how fast Teslas are.The next generation sure gets It! Even a store owner started to tell me how great the Ms Is! What Fun!

On our recent trip to California we searched out the Gilroy Supercharger spot and it wasn't easy! I think Tesla should take advantage of this and at least put up a bigger sign! I saw no sign of solar source there either. The more people that become aware of what is going on with this technology the better.

I know there is a thread dedicated to where people want supercharges. Apologies to Volker, but I couldn't find it! (Peter Spirgel)

Thanks Volker!

They have hardware ready to go, but lack approved sites.

I don't see that happening any time soon. Most are still in denial and will be for some time. That's what happened in the tire industry when radial tires were introduced. Now there is only one U.S. manufacturer left. I don't see that the car industry has learned anything from the tire industry. They are trying the same tactics and I suspect they will have the same results.

Maybe the auto industry will learn from the recently defeated Republicans. The Republicans are now saying they have to recognize a change in demographics if they want to stay relevant. That is what the auto industry must do.
