I missed what?

The quoted statement.

The quoted statement. Crissa

You mean the quoted statement that said exactly the same thing as I did?

Those are the older Charge Tanks, the 6kW ones are completely separate...

...And I don't think they're available for the S-frame bikes, either.  They're not on Zero's website, they only list the old ones.

The F-platform bikes come with a granny cable.

-Crissa

What are S-frame bikes, S/DS? The charge tank for those has been the same (in terms of fitment) since 2015. I don't know what the original model's wattage was but it was bumped to 2.5kW in 2016 and used the OBC at the same time for 3.8kW and then in 2017 they came out with the 6.5kW (could've sworn it was only 6kW) which works on its own.

It's listed at the top on this page, doesn't mention the wattage but does say it's 6x faster (1.3x6=7.8kW, so 6.5kW plus the 1.3kW OBC): https://www.zeromotorcycles.com/accessories

And it's also mentioned here but they say it's 6kW, same as the SR/F: https://www.zeromotorcycles.com/charging/

The OBC adds to the charge tank power. It would be a dumb design to not use both with  240 VAC charging.

Not with the latest model.

[Crissa]

I edited my post six minutes before your reply, where I noticed the difference.  The brochure that Don linked to is the older charger, not the new one.

They have most definitely changed since release, even if the new 2019 Charge Tank fits the 2015 models, it's not the 2017 or 2015 Charge Tank inside.

You're going to have hafta support that statement, tho.  I can't find a new manual that states that the 6KW is or is not Tank+OBC.

[TheRan]

What makes you think it would be different from the 2017? I can't find any mention of any changes, I did think perhaps it was increased from 6 to 6.5 at some point but the unofficial manual says the 6.5 was released in 2017.

[DonTom]

Those are the older Charge Tanks, the 6kW ones are completely separate (hence why the bike needs to be keyed on the start charging unlike the OBC) and will need a separate cable to be used alongside the OBC. That's also why I said it would be over 1C on a 7.2kW/h bike, 6+1.3.

Can you run both at the same time? Such as the 6 KW charge tank with 240 VAC and the OBC with 120 VAC at the same time, if you have a 14.4 KWH battery?

Even the 7.2 KWH is  close.   6.0 KW plus 1.3 KW= 7.3 KW. But the 7.2 is not the nominal capacity, is the max, so it is probably a bit over the 1C limit, as you mentioned. Do they do anything to prevent both being used at the same time on the 7.2 KWH bikes?

I would imagine you could run each at different voltages as the inputs are entirely separate, although I can't imagine many situations where that would be necessary.

Nominal is 6.8kW/h if I remember correctly so it would almost definitely be over 1C (my OBC usually starts off jumping between 900-1000W), especially it actually is a 6.5kW charger. I don't think there is anything to prevent you from using both and that's why the warning is in the manual. I would have thought that the bike would be able to tell that the charge tank is running and then tell the OBC not to run but perhaps that sort of control isn't possible.

Yes, you can. I did it after I emailed Zero, and they confirmed that is ok to do it.

Well, first, the charging times for the 2019 tank are much faster '6x' advertised on the Zero website vs the '3x' advertised in the older pamphlet.

Second, TheRan and TEV both say that the tanks are different.  I have no reason to doubt them, I just can't find any newer documentation since the site overhaul.

Different from the 2015 and 2016 sure, but the 2017 was the same 6.5kW according to the unofficial manual.

I don't think that was ever a 6.5KW, or 6.6KW  Charge Tank, the most powerful is the 6KW one, like I have on my 2019 DSR, and I believe that was intentionally limited to 6KW,  or 50A, because a 7.2KW pack is 1C at 54A , so, I guess that they wanted to be able to install it on the motorcycles that had the 7.2KW pack too. Or maybe was some other weird  reason.

Have you only ever seen 6kW (or there abouts) from the app then? Come to think of it 6kW would make more sense as it can be installed on 2015 models and those were less than 7.2, I think 6.8 (maybe even less) so the nominal capacity would probably be somewhere around 6.4-6.5. A bit strange that they'd say it's 6 times faster though.

I can't find a 2017 description except the one Don linked to.

[TheRan]

The link to the manual? That's for the 2016 CT, says so in the URL. Here's the info in the unofficial manual:

I was trying to find outside confirmation.
