Tesla Supercharger Network Expands to Include East Coast

5 years ago by Eric Loveday 15

Tesla's proposed Supercharger network will cover most of the US within 2 years.

Last Friday, Tesla Motors quietly launched its first 480-volt Supercharger stations on the nation’s East Coast.  The station, which is claimed to provide the Model S with up to 150 miles of additional range in only 30 minutes, effectively makes it possible to travel from Boston to Washington, D.C. (approximately 443 miles) in a 265-mile rated Tesla Model S.

In total, Tesla opened two roadside stations on the East Coast.  One is located in Milford, Connecticut and the other in Wilmington, Delaware.

Eventually, Tesla aims to install a network of Superchargers throughout the US.   Unfortunately, owners of non-Tesla electric vehicles will not be able to benefit from the chargers, as Tesla selfishly (?) developed its own system that is not compatible with plug-in vehicles from other automakers.

Tesla inaugurated the opening of its first Supercharger, located between San Francisco and Los Angeles, back in October.  The startup automaker then held ribbon-cutting ceremonies at four of its six initial Supercharger locations on the West Coast.  Tesla says the Supercharger network will expand rapidly over the next two years, but if you don’t own a Tesla, then these sites are completely and utterly useless.

    Being that Elon has stated many times that his goal with Tesla, even if it failed, was to spur production and development of electric vehicles. I have repeatedly heard him state in interviews that even if Tesla fails, he feels he has succeeded already because he got other manufacturers to make EVs.

    Having said that, it seems strange that he wouldn’t offer at minimum a J1772 setup for other brands of vehicles at the Tesla stations as a gesture of good will towards the EV industry.

      Maybe with simple adapter in the future we can connect?

    Welcome to the right coast, Tesla! One day I hope to own a Tesla and use this network. Until then, I will applaud every milestone.

    Eric,
    It looks like they may have added Phx to the map since I last saw it. However I have googled for an answer but can not find it. Do you have a list of cities for the proposed network in 2 years?

    Thx,
    GSB

    @ GeorgeS

    Added a graphic in the article from Tesla showing the current Supercharger locations.

    I don’t think Tesla released an actual list of proposed cities, just that non-specific map posted at the top of this article.

    I think it would make more sense to locate them along the expressways (with a coffee shop/etc) vs. in larger cities. Hopefully, in the cities, you can stay at a hotel with charger (or find a public one).

    I see a third party adapter being developed, but I don’t know how Telsa would feel about that. They may have some kind of communication protocol that won’t allow others to charge.

    1. Roy_H says:

      I believe that is exactly what Tesla is doing (…along expressways).

      Who is building the adapter? Link? Is this adapter from J1772 DC to the Tesla car or from the Supercharger to a non-Tesla car? In the first case, I would think Tesla would have no objection, in the second case Tesla probably does not want Tesla customers to be inconvenienced by finding a non-Tesla car occupying the charger location, and would include the car identification in the protocol. The adapter would have to fool the charger into thinking it was plugged into a Tesla, and this may be very difficult to do if encryption key technology is used for the identification.

      1. kdawg says:

        My crystal ball said someone would develop a 3rd party adapter. We’ll see how popular these stations are, obviously more-so for BEV’s than cars like the Volt. Seems like Telsa should just charge Leaf drivers and use the $ to offset the operating costs of the station /or whatever.

    Over the last year I have gone from a Leaf owner, very critical of Tesla, to someone now buying a Tesla. the proprietary charging system is a bummer. I would like to see more inclusiveness with Tesla. then again, with how slow and unreliable a lot of the public charging is, particularly with the Blink network and now even a few incidences of issues with overheating EVSE’s, I can see why Tesla has decided to go on their own and create what stands to be a far superior system. For EV’s to be adopted by the masses, they need to go far and charge fast. Tesla is offering the very best of the cutting edge! If they succeed, the entire EV movement stands to benefit in the long run.

  7. Roy_H says:

    I wouldn’t be surprised if Tesla licensed their charge system to other manufacturers free of charge. Of course there will be a charge to customers at the Supercharging stations. Elon Musk obviously is not impressed with the existing choices and has chosen to offer an alternative. If J1772 DC Level 2 had simply shared the AC and DC pins as one pair (the larger), I think Tesla would have adopted the standard for themselves.
    null

    As it is the J1772 DC is much larger than it has to be.

    1. Roy_H says:

      Also it should be simple for Tesla to provide an adapter for J1772 DC just as they do for the J1772 AC. Then you could charge your Tesla at these public charge stations. I believe they use the same communications protocol.

    2. kdawg says:

      I’ll put my safety in the SAE’s hands over Tesla’s (a corp. who’s chasing profits).

    An impressive demonstration of progress.

    I notice from Google Maps for the I95 Milford McDonald’s site each Supercharge Station (Nth and Sth bound) uses 72 solar modules. That is not a lot of energy capacity.

    Are the panels just for cosmetics or brand messaging and being grid tied is Telsla buying green electricity, or just whatever comes off the grid?

    1. Wolfenhawke says:

      The stations are not meant to supply charging 100% of the time. You are right, it would take many more panels to support that. The intent is to feed the grid and pull from grid when charging. Right now with so few cars it is net positive to the grid. It can be updated with more efficient panels in the future or more panels or off-site auxilary panels as use increases.

  9. Wolfenhawke says:

    The Tesla comes with an adapter that allows using a J1772 with the Model S. I haven’t been to a supercharger station yet, but keep in mind that feed is 480V DC (level 3). Not all EVs now can take that feed. The Volt certainly doesn’t — though the Leaf can — so possibly an adaptor could work for that car. It will remain to see what comes for the i3/i8.
    As @georgeLeaf notes, it is the building of the infrastructure now that is important. Smart people will figure how to reuse it.
