Interesting text from that fb post translated:

(red is my highlights)

So,
  • Stark Future rolled this feature out only for the Gotland Grand National?
  • the bikes are physically capable of accepting 6.6kW
  • the software is capable to adjust the range up to 6.6kW

When do we get an adapter cable to parallel two 3.3kW chargers for fast charging?
Thanks, that explains why they have not communicated about this.
Funny that they update all bikes just to try something new on a few customers bikes at Gotland.

Not just that but that the app auto-updates without notice or user consent.
Isn't that what "Beta" versions and testers are for?
In any case they will need to correct the wrong display of current charging power.

While they are at it they should add the time until full charge estimate like the phone charging has.

also stark numbers doesnt add up

they claim 82min 0-80%
3,3kW with 82min = 4,51kWh
4,51kwh = 80% ---> 5,64kWh = 100% :O
Maybe they meant 20% to 80% which is a common recharge span for EV and the SOC span where fastest charging is possible with lowest battery degradation over time. And that is only 60% of 7.2kWh so close to your calculation. Odd they would use a "0% to anything" spec since discharging to 0% is a no-no. My guess is the wording was "to 80%" and the fine print, somewhere, said "starting from 20%" or something like that. Ha.

No, it's pretty clear and impossible.

Weird, as mentioned earlier the maths don't line up but the claim is still here, 3.3 kWh in 82 min is 4.51 kWh, that's 69% of 6.5 kWh MX1 battery (63% of 7.2 kWh MX1.2/EX battery).

That would work for 20-80% but that's definitely not what's written here.

IF (pretty big if) by 16 A max their "3.3 kWh" portable charger could in fact provide 16 A x 220 V = 3.52 kWh, then that would be 74% of the 6.5 kWh battery (67% of 7.2 kWh battery) in 82 min.

These are interesting numbers in themselves, don't understand how they came up with this 0-80% in 82 min, overselling is not good.

It's also bad practice not to specify if these claims are supposed to apply to the 6.5 or 7.2 kWh battery. One can only assume "riders on the move" would be EX or SM riders with 7.2 kWh battery.

Today I finally got to measure the stock charger with an amperage clamp meter on the AC side. Bike (EX) was at 60% when I started charging with 1kW raising the power to 6.6kW in 0.5kW steps in the app. Amperage would top out at 15.6A at around 3.5kW and then stay CONSTANT even though the Varg app was showing kW numbers all the way up to 6.6kW. So I hope that finally puts the myth to rest that the stock charger can deliver more than the 3.3kW it is specified for!

what was voltage with this 15,6A? I am wondering if you get for example 210-215V and 240-245V this will be the same number

Hi,

The spezial 6.6kW charger would be however interesting. I have a power generator with 5.5kW constant power on one phase. Connector is a CEE 32A with one phase. Would be great to use it for faster charging at the track. Any information if this is on the roadmap from stark?

Thanks
