Tesla Unveils Supercharger Stations; Six Now in California

With fanfare befitting a Hollywood premiere, Tesla co-founder and CEO Elon Musk unveiled the Tesla Supercharger to a crowd of hundreds gathered at the company’s design center in Hawthorne, Calif., Monday night.

The solar-powered stations – built in conjunction with SolarCity, another Musk property – will supply 440 volts at just less than 100 kw. This, Tesla says, will allow the 85-kwh Model S to recharge in approximately 30 minutes with enough power to travel as far as another 150 miles.

Tesla says “at 90 kw, a Tesla Supercharger delivers 4.5 times more electricity to your battery than Twin Chargers,” and a full charge for the Model S sedans – the only vehicles that can presently utilize the Jetsonesque charger bays – could take around an hour.

“The technology at the heart of the Supercharger was developed internally and leverages the economies of scale of existing charging technology already used by the Model S, enabling Tesla to create the Supercharger device at minimal cost,” Musk said during the unveiling.

Musk gave Hybridcars.com a rough cost estimate of $20-30 million for the charge station network’s rollout. Offering a bit more detail on Musk’s cost projection, Tesla VP George Blankenship said it represents “a little less than 100 installations” as part of the company’s long term plan (see graphic below).

Blankenship also explained that station placement will be dictated by the highest concentration of Model S owners in a given region, rather than randomly placing a Supercharger in a bustling roadside commercial area.

Supercharger locations present

Of the six currently operational charging stations announced at the event, one is located at the company’s Hawthorne design studio, with the remaining stations in Folsom, Gilroy, Harris Ranch, Tejon Ranch (more correctly, the Grapevine exit on Interstate 5), and Barstow.

Musk stated he expects more stations by year’s end in Oregon as well as Nevada, with a European rollout by next year. Each Supercharger station will have four to six charging bays fitting one car at a time, as it is with current-day gasoline stations.

Superchargers by 2013

Appealing to alternative energy enthusiasts, as well as present and future Model S owners in the crowd, Musk proudly explained that the stations “will put more power back into the grid than the cars can use.” But perhaps most enticing to Model S customers is the news that the stations are free to use.

“You’ll be able to travel for free, forever, on pure sunlight,” exclaimed Musk. Tesla has not said whether after a point in time it may decide to start charging for Supercharger access, but they’re a free, if limited affair for now.

Unfortunately, Tesla Roadster owners have less to get excited about, as the stations won’t service the company’s first product, nor any other brand of electric or hybrid vehicle. Nor is it a simple matter of utilizing an adapter plug to fit other EVs to the Superchargers. Instead only Model S and future Tesla product, like the forthcoming Model X crossover, will benefit from Superchargers, effectively making this infrastructure only for present and future Teslas.

Model X and S supercharging

Tesla hired a former Apple marketer to set the pace, and seemingly copying another Apple trick of rendering its previous technology obsolete, Tesla has quickly relegated its Roadsters one step closer to outdated by not designing in compatibility with them for its new charging stations.

Also possibly raising eyebrows is Tesla’s 100-plus station long-term plan which could seem extraordinarily ambitious considering that as of the third week in August Tesla had only acknowledged building roughly 100 Model S units.

Tesla has until now maintained it will build 5,000 of the new sedans by Dec. 31, 2012, although today news that it has lowered its 2012 sales target to 2,700 to 3,250 this year, and a follow-on offering of 4.34 million common stock shares sent TSLA trading just over $30 per share into a $3-dollar (9.78-percent) decline to close at $27.66 per share today. The sudden drop also triggered Nasdaq’s short-sale circuit breakers, which shield stocks from being manipulated by short sellers.

Of the stock offering to be managed by Goldman Sachs, with proceeds designated for “general corporate purposes,” Musk has said he is interested in buying up to $1 million worth of the shares.

Model S charging

As the evening wore on, a small faction of Roadster owners were heard voicing disappointment over the exclusion of the Roadster from the charging network.

One female Roadster owner unabashedly said that as an early adopter of Tesla she “helped build this company” but now feels left behind by the brand with the advent of the Supercharger.

Tesla explained, however, that it’s simply a matter of hardware; the Roadster isn’t capable of accepting the power dispensed by the Supercharger. We are unsure as of deadline what hardware would be required, or its cost, to potentially retrofit a Roadster. Also unknown is the likelihood of such a possibility, and the notion was not broached by Tesla at last night’s event focusing on present and future models.

Supercharger long term

As for cars the few Teslas that can use the Superchargers, according to a Tesla staffer, the rate of charge from zero to 80 percent is the same, while the charge rate for the remaining 20 percent will vary, with the charger and car’s software systems communicating to decide how quickly to complete the full charge. To determine this, the system will take into account things like the condition of the battery and numerous other data. Expect a complete battery charge, zero to 100 percent, to take approximately one hour for the 85-kwh Model S.

Supercharger launch gathering

Referred to by Musk as “rest stop” locations, the stations’ locations to date are more aptly described as being in commercial, highly trafficked areas like truck stop locations with shops, restaurants and the like, rather than the department of transportation-style restrooms located along state highways. For now the Superchargers are co-located with existing business property; the Tejon Ranch station is located in the same lot as a Yogartland, according to a member of Tesla’s marketing department.

The space-age design of the Hawthorne station is what Tesla would hope each station could look like, but the reality is that the appearance of each station will be restricted by local planning ordinances. The Tejon Ranch station is borderline Spartan and industrial looking, lacking the sleek shapes of the Hawthorne installation.

A two-year plan displayed on a map of the continental U.S. had numerous dots representing hoped for locations in much of the country, while a “long term” plan revealed charge stations throughout the U.S. and various locations in Canada.

Tesla’s monolith is essentially an icon intended as identifying signage for each location, rather than being a functional aspect of the chargers.

With the dizzying array of information available to the Model S driver on the car’s 17-inch touchscreen display it’s conceivable that the car could route to the nearest Supercharger, or list any stations within range, but as of now that feature doesn’t exist according to Tesla. Nevertheless, a simple software upgrade for the Model S in the not-too-distant future might include a Supercharger location routing feature, and perhaps even allow drivers to reserve charge time in advance of arrival – all of which Tesla said is very likely.

    Reminds me of the monolith in 2001 Space Odyssey. 300 miles charged in an hour is insane. That’s 50 miles in 10 minutes… wow..

    Excellent. This is called EV (Electric Vehicle) + PV (Photovoltaic) and its a great combination. I guess the solar power will also be stored in batteries.

    Let these charging stations be the new MacDonalds.

    Great company, Great Product, Great Ideas.

    There are 13,000 EV chargers in USA, let this complement those. Ideally all auto dealerships should install an EV charger. Soon these charger count should exceed the 160,000 gas station count.

    Hi there! I know this is kind of off topic but I was wondering
    which blog platform are you using for this site?
    I’m getting fed up of WordPress because I’ve had problems with
    hackers and I’m looking at alternatives for another platform. I would be fantastic if you could point me in the direction of a good platform.

    Not to rip on one of the most inovative companies of our time but the charge kw demands of these stations can’t possibly be supplied by the carports roof top panels. If we assume that the carport is 60 feet long and twenty feet wide that gives us 1200 sq foot, using a optimistic number of 15 watts per sq foot we only get 18000 watts in pannel output. On a good sunny day we might get a u.s. average solar insular radiation factor of 5 bringing us to a grand total of 90 KW or just one hour of full out put per rooftop carport solar charging station. not nearly enough to handle 4 or more cars in a day let alone every hour. Musk clearly states that these statioins will be capable of producing far more power than will be used andall exess will be sent back to the grid. Has Solar City developed a pv pannel with greater than 20% efficiancy?. Needless to say this is all a mute point because fewer than 3% of any cars milage will be attributed to trips over 100 miles. Americans simply dont drive as much as we think we do. That beeing said I cant wait for a Model x.
