Tesla’s Jerome Guillen Promises January Arrival Of Model S CHAdeMO Adapter


The Tesla Model S to CHAdeMO adapter will go on sale this month, promises Jerome Guillen, Tesla’s vice-president of worldwide sales and service.

That promise was made by Guillen at the opening of Tesla’s store in Montreal last month and confirmed again just days ago at the 2015 NAIAS.

Tesla has quietly been shipping the CHAdeMO adapter out to beta testers for quite awhile now, but within the next few days or couple of weeks, all Model S owners will be able to order the CHAdeMO adapter directly from Tesla’s store for $450.

The Downside To CHAdeMO Adapter Availability?

As more and more Model S owners get the CHAdeMO adapter, lines will become longer at some of the already-overcrowded CHAdeMO chargers.

More quick chargers will be required at some locations where Nissan LEAF owners report waiting in lines 4-5 cars deep for a quick charge.

    More cars using CHAdeMO, means more revenue for the stations and hopefully more investment.

    The couple thousand extra Model S owners that buy the adapter using the stations does not have as much effect as the 30k extra LEAFs sold in 2014 that all have a short range.

      1. Speculawyer says:

        Yep. Lots of Chademo around there because they build the Leaf around there.

    2. Sublime says:

      I get your point, however:
      1) Not every LEAF has a QC port, in fact a significant number don’t.
      2) Not every LEAF owner with a QC port uses it, much less often.
      3) I would predict that most Tesla owners that buy the adapter, have a location/use case/intent to use it in mind when shelling out the $450.
      4) Tesla’s could use a station 2x-3x longer than a LEAF

      1. Speculawyer says:

        #4 is an interesting point. I can imagine that a Nissan dealership would not be keen on some Tesla hogging their Chademo charger.

      2. Brian Henderson says:

        1. Over 80% of LEAFs have CHAdeMO.
        2. $450 for CHAdeMO adaptor is less than a couple 21″ tires … and a Tesla owner will get more milage from the adaptor than the tires. 😉
        3. In 30 min. a LEAF will add at most 15 kWh while a Model S will add 25 kWh from same 50 kW DCFC. (who gets better deal? p(aying by kWh, minute, or by session)
        4. after an hour a LEAF will have charged ~21 kWh (~74 miles) while a Model S will have charged ~50 kWh (~175 miles) … Why would an S owner stay longer than an hour when they can travel at 2.5 hours at 70 MPH to a Supercharger, another CHAdeMO, or to a 20 kW Tesla HPWC?

        1. Marshall Banana says:

          What’s an “adaptor”? Some kind of raptor?

  2. Yuba says:

    I think the adapter roll-out could work out really well for both the Tesla drivers as the DC fast charge station operators.

    As a driver you could charge for free at a supercharger, but when there is none on your route you could choose to use a CHAdeMO charger at a convenient location, and pay. I think not many Tesla drivers would mind some payment now and then (you are not using it everyday, only occasionally)

    So it increases the freedom to drive anywhere, while providing revenue for the operators, which will lead to more investment in infrastructure.

    Perfect circle!

    1. Brian Henderson says:

      It’s great news for BEVs with both CHAdeMO and Tesla plugs. In the US the total number of LEAF’s and Model S’s now number greater than 100,000 and will pass 150,000 in 2015.

      While Superchargers are mostly on freeways between major cities there are few fast DC charging options for Model S’s around urban areas. This aligns with the needs of LEAF owners who do most of their driving around urban areas.

      For EVSE there will be a much larger (and under served) population of PEVs looking to use DCFC. For network operators and hosting sites, it means potential of 6-12+ charging sessions per day vs. 1-2 for a Level2 charging point. Hopefully this is incentive to deploy more DCFC locations in urban areas with multiple charging point stalls.

  3. Marc says:

    This is news… from last August. Given Tesla’s track record on delivering products when they originally said they would, I wouldn’t hold my breath.

  4. taser54 says:

    I think there’s going to be blowback from other EV owners if this adapter use becomes widespread. A Tesla sitting at a typical 50KW CHAdeMO charger for an hour is not going to be popular with other EV drivers, especially when most CHAdeMO chargers are single stalls.

    Not that it matters to me, but I can see this forthcoming

    1. Jon says:

      if i owned a tesla i would only use it for emergency and only chare enough to reach a supercharge. who would won’t to sit a a chademo charger for hours

      1. Stimpacker says:


        The typical Tesla owner will not have free charging access to a CHAdeMO station so he/she will likely avoid using it at all.

        PJWOOD raises a good question about etiquette. You don’t wanna hog a station that in some cases, Leaf owners might really need a charge.

        Similar to what I see around here – Plug In Prius owners hogging chargers for HOURS just because they have a plug. Finally saw a PiP hogger the other day, his PiP wasn’t even charging for at least 3 hours but was plugged in. He went to his car to put something in. I asked him to move and his response was “there’s nowhere else to park”. More accurately, there is nowhere else convenient – he just wanted the nice spot and didn’t want to walk. This isn’t an isolated case – 50% or more of PiP’s that I see at charging stations are not charging.

        1. Yep, that’s a policy problem. I saw a Volt driver park in one of two bisy charge spots and walk away without plugging in. When I helpfully pointed out that he had forgotten to plug in, he replied that he didn’t need to charge and kept walking.

          This is a solvable problem, but it requires a little thought and effort on the part of property owners, EVSE manufacturers and lawmakers.

          Or a valve stem removal tool.

          1. Woor says:

            I like the valve stem tool and solve that problem.

    2. Brian Henderson says:

      At a 50 kW charger a LEAF will charge at an average ~70 MPH vs a Model S which will charge at 175 MPH.

      I don’t see a Model S spending much beyond a 30 min. session unless they won’t be able to find other charging options having added 80-90 miles.

      More likely is a LEAF waiting an extra 30 min. to go from 85 to 95% (about 10 miles range, or charging at 20 MPH).

      The 30 minute maximum session limits becoming more common at DCFC should help to keep all happy unless there is along queue at a DCFC.

  5. Anon says:

    Great example of elegant design meeting a clunky industrial style standard. The result; is an awkward abomination of an adapter to bridge the gap.

    Considering they’re essentially mating a Clydesdale-sized adapter into a German Shepard form factor, Tesla’s solution is still more streamlined than I would have expected.

    1. Kosh says:

      …and all for just a 3 (or 5?) wire connection….

      1. scottf200 says:

        … that you can safely plug in in the rain or snow … (ie. it may seem simply but safety is paramount)

        1. Jon says:

          The Model S plug is just as safe. You can drop it in standing water, pick it up and immediately plug it in with no worry or risk. I have plugged in at superchargers during torrential downpours and the thought of electrocution never once crossed my mind… What was going through my mind was, crap I am getting soaked trying to plug this thing in! (Would really love more overhangs on top of the charging area, haha!)

          You don’t have to be big and ugly to be safe.

  6. Omar Sultan says:

    I think for most owners, this is insurance, not their primary method to QC.

    1. Edward Arthur says:

      Yup, it will be destination charging

      1. Brian Henderson says:

        If you call extending range by 30-40 mies in 10-15 minutes destination charging? The charging speed using 50 kW CHAdeMO would be ~175 MPH depending on SOC.

  7. pjwood says:

    This helps, but I also wonder the etiquette issues of Leaf drivers stumbling upon Tesla owners?

    Triangulating a trip, for a SC, can’t make as much sense, even considering the slower DCFC. I think CHAdeMO will be viable waypoint charging “if you have to”, for Tesla owners. Otherwise, the superchargers will continue to define Tesla’s luxury.

    How many lines do Leaf owners find themselves in? Do the CHAdeMOs report occupied status, like Chargepoint?

    1. Bonaire says:

      You will get lines at places with free DCFC stations. Charge a fee and it will drop. Fee should be based on an upcharge above the utility rate kWh charge, perhaps double the current kWh rate for such convenience charging. .20/kWh or so. As long as it is not the predatory .49/kWh that we saw Blink charge in NYC garages for J-1772. Lines will form only for those travelling by EV and not just getting free opportunity charges to bypass charging at home.

      1. pjwood says:

        I totally agree on the fees. There’s a docket, in MA, from the Dpt. of Utils, probing that idea as a way to relieve DCFC owners of demand charges. They want to waive them, but only temporarily. That won’t be a good LT solution.

      2. Mike I says:

        Commercial power rates in CA are above $0.20/kWh even without demand charges. So doubling is almost up to the $0.49/kWh you mentioned.

        1. Mike I says:

          Correction: rates have changed in the last year. PG&E A-6 would be the most likely rate to apply to a site with up to 3 CHAdeMO/SAE DCFCs and a couple Level 2 stations. (199kW peak demand max) There is no demand charge on this schedule.
          Fixed monthly charge for 3-phase is about $25/mo.
          Summer Rates are $0.49/$0.26/$0.16 per kWh Peak/Part-Peak/Off-Peak
          Winter Rates are $0.18/$0.15 per kWh Part-Peak/Off-Peak
          Peak times are Noon-6pm M-F
          Part-Peak is 8:30-Noon and 6:00-9:30p M-F
          Off-Peak is all other times including all day weekends and holidays.
          There are also 9-15 days per year designated as Peak Days, with day-ahead notification when the Peak price is $1.20/kWh for all usage between 2pm-6pm.

  8. ModernMarvelFan says:

    LEAF owners will suffer now b/c they have to wait for Tesla owners to finish… LOL. Especially those free ones.

    I wonder what the Nissan dealers feel about offering Tesla owners some free charge…

    1. ItsNotAboutTheMoney says:

      Generally, they don’t mind. Helps promote the Leaf. There are Tesla+Leaf households as well.

  9. John F says:

    So if Tesla wants to promote the use of electric cars and flexible charging options, will they also introduce the adapter that lets the Leaf driver use any supercharger? The supercharger just has to hold back on the rate of charge for the LEAF.

  10. jstack6 says:

    most of the CHAdeMO locations we have don’t work. I’d rather just get a Tesla GEN III and use the Super Chargers that always work.

  11. MThompson says:

    Solar on roof + electric vehicle + battery storage = no-brainer!

  12. danwat1234 says:

    Is there any news of a J1772 Combo adapter?

    1. Yes, there is word: Elon said they won’t make one for the CCS interface!
