Tesla Motors Brings Revolutionary Supercharger to Europe With Launch Across Norway

Tesla Supercharger in Norway

Well known Tesla Model S enthusiast Bjørn Nyland recorded and prepared an interesting timelapse video from supercharging his Model S.

Shown are two examples at two different sites (Lier and Gol in Norway).  However, a different state of charge and temperature, plus different firmware on the car, do not allow for direct performance comparisons.

In both cases, charging begins at 100-110 kW (over 330 A in Lier) and gradually slows down to about 70 kW at half charged pack and then to some 50 kW at about 75%.

In Lier, drawing roughly 58 kWh, took 46 minutes and it was a best-case scenario (lower 58 kWh from 85 kWh battery pack). The lower the state of charge, the more juice is drawn.

Despite Tesla saying that Superchargers are 120 kW ready (or even 135 kW in Germany) and they are, charging power drops below 100 kW after 1/3 state of charge. To fully utilize Superchargers, a new type of battery will be needed, which will accept all the available power and charge maybe even 10-15 minutes faster.

    In practice, Superchargers are fast enough already.

      Yeah, boo-hoo, 50 kW at 75% SOC! Each supercharger feeds two stalls so it is not as if the maximum power capability is wasted. And can I please get a couple of freakin’ minutes to enjoy my freakin’ coffee?

      It’s still one of the Achilles’ heels of EV’s (even though Tesla does it a lot better than anyone else) so every increased kW and minute cut from charging time is important for the implementation of EV’s.

      There is a big difference between 25 min for every stop or the 20 minutes needed if the battery could take 120 kW continuous. Or if they make it 150 kW (16 min) or even 200 kW (12 minutes) continuous.

      Every improvement will count.

      No, not at all. Charging at home at 22 KW is ok but if you are on the road we need true fast charge. For the moment a low 135 KW but we need more up to 1000 KW which is one megawatt, at that moment we we be able to speak of hyperchargers and indeed be on the go after 5 or 10 minutes instead of 40 minutes and more at present. Beyond the megawatt level it indeed makes less difference but for now the improvement course need to be maintained to make gasoline vehicle something of the past for whatever driver.

        Since BEVs are rapidly headed to 100 miles of range, or more, I wonder just how likely it is for anyone to not only run those miles down, but go out again, in need of the ~30 miles the 10kw chargers put back in ~1hr?

        For a Tesla owner to need 22kw in the garage, says to me he’s already done well over 200miles, yet needs to get right back on the road to do another 50-100 miles, in less than an hour. If I expected to need to do that often, than I would also simply call 22kw home charging “OK”.

      2. That idea is only in your psyche. No one needs a stressful speed life.

    Gotta wonder if additional cooling would help both charge rate and discharge capability (aka making it around Laguna Seca a few times before going into limp mode)..

    Excellent music choice for the first part of the video… sounds just like a Tesla event where Elon Musk takes an hour to come on stage! I felt right at home.

  4. Uromd says:

    An additional benefit of faster superchargers is that this would make larger battery packs unnecessary.
