I was just watching a video regarding the 2022 FXE and what jumped out at me was that it takes over 9 hours to charge the 7.2kWh battery. That's the same amount of time I've seen quoted to charge the 14.4kWh battery in the SR/DSR. Does that mean the FXE only pulls half the amps from the socket?
-
Yes. It only has a 650W charger while the others have a 1.3kW charger.
-
But you get 9.5 hours to think how much less weight you are carrying.
-
I prefer to sleep while my FXS is charging.

Out of curiosity I looked it up and the 1.3kW charger is only 4.7kg heavier than the 650W. Also a 7.2 S is only 11kg heavier than an FXS.
-
Yeah pure sarcasm on my end.
That's back to back funny posts that fell flat. All well.
I was complaining the new FXE doesn't have one of the new 3kw chargers that the SRF/S has. No good reason not to as it stays well below the 1C limit while making a range extending lunch stop charge up worth while.
-
Definitely agree. Until I bought an external charger and clamped it onto my FXS, I was entirely unable to do anything but my daily commute or a chill cruise (<100mi). Now it's actually a usable motorcycle. :P

Do you suppose they use the smaller charger because of the battery warranty? It's not going to make much difference if you charge occasionally at a higher rate when on a longer trip but if you doubled the charge rate every time you charged for the life of the battery that might have an adverse effect. Even with 650 watts it will always charge overnight. Are they protecting us from ourselves maybe?
-
Pretty much. Also, AC chargers are pretty directly limited in their size by their power.

That can't be the reason because they're fine with the 7.2 S/DS having a 1.3kW charger or even a 6kW charge tank.

Purely a cost concern. Aftermarket chargers run $600+ for 3.3kw, now imagine a nice OEM unit, like the 6.6kw charge tank, it cost 2.3k. They certainly could price the fx/s/e a few grand more, but then why not buy a beefier model?

Gotta remember too that those cheap chinese chargers don't meet US emissions regulations, and Zero has to meet those as a manufacturer. They had to develop their own 3kW charger with a 3rd party, and it's too big to fit on an FX in the same spot. Plus the J1772 inlet is larger too. So that's a new frame too.
The FX was designed many years ago, and chargers weren't nearly as small and efficient then. If you ask me, in the next 2-3 years we'l see everything that's not based on the SRF tech get replaced with an SRF variant. S/DS/DSR/SR/FX all will get replaced. That reduces the number of parts, updates the screen and app, improves charging, and gives them the greatest return on investment.

I think this is what we were all hoping for with the FXE. Maybe it was just me, but it was a let down.
-
I think that, instead of calling it the "FXE" (which indicates a brand new bike) they should've just called it the 2022 FXS.

The problem with that is they're still going to make the FXS (with the new dash from the FXE), however they could've called it the Huge Design edition similar to how they have the DSR Black Forest.

And that was silly because it just adds to the confusion, not to mention they now have to keep manufacturing two different sets of bodywork and instruments. Well, technically they would anyway because a lot of those same parts go into the FX but once that model is replaced they only need to make the parts for damage replacement purposes.

Yeah, I'm with you there. Zero's pretty small. If the trademark discoveries hold true, then we might see a DSR/X this year. That could be a really neat bike. I question their ability to design more than one completely new bike per year, so maybe its just not time.

Emissions regulations? Maybe they don't meet UL electrical standards (assuming they apply) but that has nothing to do with emissions.
-
Electromagnetic emissions regs. Radio interference etc. etc.

You got it Cas. For Zero to include anything on their bike, the whole bike has to meet US FCC part 15 and EU regulations for radiated and conducted EM emissions. There's a whole round of expensive multi week testing in a lab with expensive equipment to do that work. Chargers and long cables are notoriously difficult to integrate to meet those requirements, and nobody does it unless they have to. The Chinese chargers simply produce far too much EM noise to add. If it was as simple as buying a bunch of faster chargers on alibaba and integrating them, Zero would have done it, and not developed their own parts with a charger manufacturer for a much larger amount of money.
I once asked one of the Zero engineers why they didn't use the Diginow chargers, and his answer was that it was impossible to add them and meet those requirements.. Chinese parts aren't held to the same standard, and often choose not to meet them to reduce costs. Third party manufacturers have a narrow exemption and aren't held to them either, which is why they can even be sold.

Here is the type of stuff new electronic devices have to go through. (https://www.fcc.gov/oet/ea/rfdevice) Switching power supply type chargers, as are all EV chargers (AFAIK) but out all types of garbage.
If it were not for this type of stuff, it would interfere with all types of radio stuff down the block.
At my house in Auburn CA when I set up my ham gear, there was so much noise I could not use it. No other real close by houses and this was very strong noise (hams call it "QRN"), so I assumed it was coming somewhere from my own house.
So I got to my CB box and turn off a section of the house at a time.
I get to the garage, and the noise is totally gone, not even a trace.
It was caused by the old version of one of these. (https://www.harborfreight.com/6v12v-2-amp-3-stage-microprocessor-controlled-automatic-battery-charger-57015.html)
Would anybody like to guess why we cannot buy the older version any more?
