    Hi,

    this was the 1st. ever 24h-race for electric vehicles, each team had a box with 3-phase 32A (22kW AC-socket), organized by Rafael de Mestre, known for beeing the 1st. person travelling arond the world in an ev (...off course it was a Roadster)

    Burning rubber, not petrol

    here's some tv-reports, unfortunately in german:

    http://teslix.de/ZDF24.mp4

    http://teslix.de/MDR24.mp4

    the roadster is a 2010 sport 2.5 with ChaDeMo, we used an MDC44 ChaDeMo-charger, limited to 22 kW so charging-wise we weren't slower than all other vehicles (charging-speed app. 60 miles/h). as most here know the Roadster is still one of the most efficient ev's ever made, we finished 14 laps ahead of a Hyundai Kona with an overall consumption of roundabout 150W/mile and don't forget it was cold (5°Celsius), 60% in the dark and 5 hours with rain !

    all Model S were chanceless due to their much higher consumption, best Model S was our own (2nd team), finishing 10th with an overall-consumtion app. 190W/mile, it's a 2014 standard 85 with roundabout 110.000miles on the odo (...beating 11 other Model S/X) :)

    After all it was loads of fun, also with all those other teams participating (also exotic vehicles like a self-converted mini-truck with 85kWh-battery and a Twike).

    If it happens again we'll be starting again with the Roadster and the ambition to win - as you all can see the Roadster wrote history AGAIN :)

    what was the distance traveled in this 24 hour?

    Then I miss something?
    You begin with a empty accu?

    Because you can charge with 60 miles a hour, so with a total charging time of 11 hours you can reach that 650 miles.
    Then you have 13 hours to drive that empty. (average of 50 mph / 80kmh)
    I had something in mind of 15 hours charging (give 900 miles of range). And empty that in 9 hours. with a average speed of 100mph. (160kmh)
    And that is only when you begin is empty..

    jep, you missed something.

    a) we were allowed to start with a fully charged battery
    b) our Roadster is equipped with a ChaDeMo-kit, so yes, we were able to charge app. 60mph
    c) it wasn't a high-speed-event, at no time we drove faster than 70mph

    a main difficulty was, that using ChaDeMo you can only charge your car when your charge-status in range-mode is >60miles,
    otherwise ChaDeMo won't start (it seems to be a JeDeMo sw-problem) and above app 75% charge the charging speed decreases,
    means current goes down, so to have the highest charging-speed and most performance you use actually "only" 50% of the ESS-
    capacity (!)

    well, however, we managed and made it :) ARS_1759_int.jpg ARS_3055.jpg

    Watch out for a LR RWD Model 3 next year. Should beat on efficiency.

    I wonder with a 3.0 battery and normal 17 kw charging if you would do better as you would start off with 100 extra miles of range and you could run it lower as the AC charger works well at low states of charge.

    yes, you're 100% right - next year it'll be much more difficult, especially with upcoming Model3 in Europe. Unfortunately we don't have a 3.0 pack yet and Tesla doesn't have an estimated delivery-date (pack was ordered years ago !).

    anyway, we'll be there again ;-)

    Outside the spirit of it, but it would be nerdy fun to bring a stack of power walls to fully utilize the 22kW power feed. Charge them while on track, then fill the car at a faster rate.
    Hey, it's still all Tesla.:)

    well, that would be great, but the rules are defining a maximum current of 32A while charging and the mayors are controlling that -

    after all we want to win within the rules, not with cheating - and don't forget: driven wisely the roadster is still one of the most efficient ev's ever made !

    we're confident, next year we'll be back with TWO roadsters ;-)

    Oh sure. Just being pedantic about whether the rules state power from the wall or power into the car. (32A at what voltage ;))

    Then thinking about an X with a Li-ion trailer, pickup, or semi being the top vehicle due to initial pack charge...

    Congratulations for not only beating all the other cars entered but also all the theoretical cars entered for next year. Absolutely a great achievement racing in an unknown environment. Did you prep the car prior to racing?

    well, preparation wasn't much done. one thing important (knowing the race was mostly dark and cold) was a preparing the windscreen with anti-fognano-treatment from the inside and anti-rain nano-treatment from the outside (as used in helicopters), as well as sticking a 10 buck rubbishy D.I.Y-store camping-fan on the dashboard, powered by a 12V starter-battery in the passengers floor-area not to use the board-heater (as you all know it terminates loads of energy wich is better used for propulsion) and equip all drivers with "hot-packs" in gloves and shoes :)

    luckily we had a set of Toyo energysaver- tyres (unfortunately they don't make them anymore). otherwise, besides the JeDeMo-kit, the roadster is standard, but extremely well kept by it's owner (in german TFF-forum: "schrottix").

    be asured that throughout all those tv- and radio-reports and upcoming public interest (we're far away from ev-acception as you find it almost anywhere outside Germany) next year there will factory-teams starting, from all those german car-makers who demand for themselves beeing the leaders in ev-technology :)D:p:D:p:D) like volkswagen, audi, mercedes, porsche etc., and they will probably do everything to win. so to prevent cheating in any way there'll be no chargers allowed by EcoGP-organizer Rafael de Mestre, besides "official" chargers (ChaDeMo, CCS etc.) with a cord and red CEE380V/32A(3 phase). no buffering, no supporting-packs, no compensation. means: same chances for any starter.
    the ChaDeMo- kit being an official aftermarket extra makes it legal and possible to start again with a roadster and off course we want to defend our title - as i wrote above: if things go right we'll have two roadsters aboard - after all we signed in allready:)
