I Don't think I will make some modification now, my bike is warranty yet.

Have you a good place where I can find J1772 connector (socket) male and female?

I can build adapter to insall between the chargetank connector and charge station (J1772)

Nothing in this thread seems like reliable reporting.

Do not build a DIY connector unless you receive training from a qualified electrician and have the crimps examined by an EV expert.

The only valuable outcome from this thread would be if someone verified by direct observation whether the new 6kW Charge Tank energizes the onboard charger. No parsing of the OEM documentation counts. You must check the onboard charger for warmth at its casing surface, and no the belly pan does not count, either. A log report with timestamps corresponding to a manually initiated J1772 charging session would also be helpful, but primarily I want to know whether the charger produces heat.

@BTR

A Direct observation with no statements, just math :

It is known 54A output. I believe a few people have posted photos with the output sticker on it.

Bike voltage range 90 vdc - 116.4 vdc

54A * 90 vdc = 4.8kw
54A * 102 vdc = 5.5kw (battery 50%)
54A * 110 vdc = 5.9kw (battery 80% where cutback should start)
54A * 114 vdc = 6.1kw (battery in the 90%s absolute max that could have full power, but probably shouldn't)

I will let you guys decide what this means, but its just some basic math based on known values.

Ok, so I took a closer look at some stuff and the AC is not shared between the two and for some obvious saftey reasons.

Now that said, the charge tank seems to assume it is the only thing on the j1772 station, so if you were to ha k your onboard into it as well, it could trip the station by adding an extra 1kw to the numbers I shared above.

If you have a powerful station it would work. Otherwise it would just trip it.

Thanks for providing measurements and observations, and particularly ones that can be tested by others.
