Video: Bjorn’s Tesla Model S Road Trip – Testing Out 22 kW AC Charging


In this latest Bjorn Nyland Tesla Model S road trip video, Bjorn travels 872 miles en route to Bergen, Norway.

Along the way, Bjorn tests out some 22 kW Type 2 chargers.  He boils some water, too.

In typical Bjorn fashion, there’s a fair amount of humor along with some knowledge to be gained by watching this video.

If you’ve been following Bjorn’s series of Model S videos, then you’re probably accustomed to his liking to take lengthy trips in his packed-with-unusual-items Model S.  This video won’t disappoint in that regard.

The “boiling water with charger” is at 14:50.
So what is that: just a typical 220V plug on the charging station as found in europe? Did he use an adapter or was the tea pot 220V also….we don’t have 220v tea pots in the US.

Everything is 230V in Europe.

a big Dahh on my part.

Actually, energy-hungry appliances (cooktop, dryer etc…) are usually 3-phase, and use the 400V available phase-to-phase instead of the 230V phase-to-neutral.

But yes, I know of no 110/120V anywhere either.

I had no idea the S had the equipment on board to handle 22kW AC. My understanding was that there’s patents that make very high power AC charging (that is, inverters) expensive to build in the US, which is why it’s unheard of here. This is exciting news. I imagine that it is cheaper to build a charging station with 22kW AC rather than a DC Quick Charger, because the inverter is a large expense. For cars under 25kWh (everything but Tesla), 22kW is very nearly as good as Chademo as far as charging time is concerned. So, a cheaper AC station could deliver almost the same value to customers as a more expensive DC QC.

why couldn’t they just use the 2, 10 kW chargers on board the tesla

No. 22 kW takes twice the time of a 50 kW Chademo to charge to 95%, when comparing charging of a Renault Zoe and Nissan Leaf.

No, it only takes about 20-30% longer depending on what your state of charge is when you start, at least with a LEAF. The charge rate does not maintain 50 kW for very long.

Well, Fuji Electric, who manufactures(ed?) 25kW DCQCs, was claiming that its equipment could charge a Leaf from 0 to 80% in 1 hour.
And unlike AC, having the charger feed DC eliminates further conversion losses in the vehicle.

22kW AC would indeed be twice as slow as the usual 120A or 125A / 50kW DC, until approximately the top 1/3 of the battery.


22ks AC ist the future standard charging Speed in Europe. DC is defined as fast charging with CCS with up to 170kw. Other charging methods like 43kw and 86kw AC and CHAdeMO or Tesla DC are defined as vendor specific.

The current situation in Germany:
1. Typ 2 (3512), davon 4 x 43 kW, 2470 x 22 kW, 940 x 11 kW, 93 x 3,7 kW
2. Schuko (2833)
3. CEE Blau (438)
4. CEE Rot (411), davon 2 x 43 kW, 118 x 22 kW, 291 x 11 kW
5. CHAdeMO (51), davon 21 > 43 kW, 30 43 kW, 3 < 43 kW

The Future is not written, maybe Teslas DC will be THE DC Standard 🙂

Who knows.

thx for the input.

If one is charging with the 22 kW A/C outlet that is shown at 20:39 in the Video, it appears that the car owner must supply his own EVSE (charging cord/device). Does Tesla offer a 22 kW EVSE? Does it come with the car?

In EU you must supply your own Type-2 (Mennekes) cable. The cable has integrated resistors or some other passive way to signal the current carrying capability of the cable. This is a foreign concept to Americans who are used to their J1772 (Type 1) stations (home and public) always having a permanently attached cable.

I’m still confused about what charging cord he is using in the video at 20:39. The 22 kW power is only an outlet. Therefore the Tesla owner must be supplying his own mobile charger. In the Video, the Tesla owner claims he is charging at 18 kW. How can this be.??? The biggest mobile charging connecter that Tesla offers is only 10 kW.

The Tesla S in Europe has a modified Type2 plug for charging. It can fit normal Type2 cables and supercharger-plugs which are also modified Type2 here. You can buy the Tesla with an 2-11kw or an 2-22kw charger (they call it double-charger). So, normally you have a regular Type2 cable in the car to fit the Type2 charging stations, and you can have some adapters (Schuko, CEE and even ChaDeMo from Tesla). The car does the rest, no EVSE needed.
You can also see in the video that the car is charging with 26amps, normally 22kw would have 32amps. Don’t know why that is, but we all know that the Norwegian grid is kinda picky. In ideal conditions he should be able to get 100km/60miles an hour with 22kw/full 32amps. Telsa is advertising this in Germany.

26 amps at 230Y/400 would be 18 kw. Tesla exaggerates the numbers a bit. They say the North American Tesla charges at 10 or 20 kw, but those numbers are bogus for the reason that to allow for System Excursion you don’t run your equipment on an unregulated circuit right up to the bitter limit. On the website, the maximum voltage for the EVSE is 250 volts, but you only get 10 or 20 kw charging at 250 volts (very uncommon in North America). And anyone professional who’s been around Tesla electricals knows there’s not any safety factor to spare, what with hot running UMC Plugs with the S (did Blink design those things?), or the Roadster $1500 UMC’s that keep burning out. At 200 you only get 8 or 16, but that doesn’t sound as good as 10 or 20kw. But 200 volts is far more common than 250, even at an authorized Tesla Service Center. The last time I was at one, my Roadster was charging at 204 volts @ 70 amps, and a neighboring S was charging at 196-197 volts @ 40 amps. ( I do note that currently on the Tesla S website, they’ve changed some… Read more »

Thanks for the numbers. Wow, what a mess. And I had no idea Germany was so behind. Only 57 stations 43kW or higher for the whole country??
Out of the 1000+ CHAdeMO stations in Europe, they’ve only got 51, ie 5%?!

If those statistics are correct, that’s pretty pathetic. Good thing that Europe isn’t just Germany…

Yep, can verify that. No incentives, not much fast charging – no wonder people don’t buy many EVs here. Maybe Teslas superchargers will make a difference. Would help a lot if Mercedes would be willing to work out a deal to let it’s B-Class EV use them.

BMW, VW, Audi and the others need to do what Nissan did in California… donate fast chargers and help with the installation cost. For them, it would be the Combo Plug (CCS), but Ecotricity has shown that you can put a dual-format fast charger in the ground – CHAdeMO + CCS!
