I noticed a new promotion on the SR and DSR, headlined as "maximise your ride".

Interestingly it includes the 6kW charge tank upgrade... I wonder if it truely is maximised in charging terms beyond 40% SOC?

Does this constitute false advertising??   

Paul.

Thanks all.
I do have breakdown cover, I think if it snapped i'd have to go for a tow anyway because I doubt a roadside change would be practical.  I was more curious if others agreed.

I saw another interesting article from Dennis NL, he uses Silicone spray and has some positive stats on logevity...

I think i'll take others advice and just stock a spare.  Seems a replacement is inevitabe.

    version:  SR/F
    bike production year: 2020
    years you have used it: 4
    km you have put on it?  10k

Issues thus far:
1. CCM failure, replaced under warranty
2. Front brake micro-switch failures x 3 (all original black seal ones,  now got new orange seal one on)
3. Battery "magic charging", replaced with 17.3kWh pack under warranty.

No more warranty so got my fingers and toes all crossed. 

I emailed the UK country manager.  I’m not expecting to hear back but if I do I’ll pass on.  I agree, the charge tank is pretty useless. 
I’ve just done a 500mile trip and it appears to be an algorithm based upon SOC…
If SOC < 40% then max power. = 11.8kW
Then it decreases going up the SOC range but very consistently…
40-50 = 10-11kW
50-60 = 9-10kW
60-70 = 8-9kW
80-90 = 7-8kW
90+ = 6kW

It doesn’t seem to matter what SOC I start the charge at or whether the bike is hot or stone cold. 
So I’d hazard an educated guess that this is a deliberate move from Zero to throttle the charge rate going up the SOC range.

Very annoying.    The tour-ability of the bike is severely impaired when the 10%-90% charge time is now about 1.5 hours.  It used to be 45mins.  Mind you that’s with 12.6kWh usable, there’s an extra kWh in the 17.3 pack for sub 2022 models that had the pack replaced.   But still is a noticeable hanging around that my ICE mates aren’t up for. 

Does anyone know if this behaviour is common to 2022+ models and other platform bikes? SR/S and DSR?

Cas,

What battery are they using for replacement do you know?  Is it the newer bigger BCB battery?

Thx,
Paul.

You barely even need the logs to prove it - in my case all I had to do was ride 23 miles, observe the battery SOC at 65%, and then come back to the bike a few hours later to discover it had charged itself back up to 75%.

My dealer down in Torquay (Davant) managed to pull the logs successfully after I dropped it off and then presumably pulled them again a few hours later, and that was enough for Zero to acknowledge the issue and send me a new battery under warranty, which is apparently being fitted today (hurrah!)

Has anyone tried to diagnose/demonstrate the SOC symptoms from the 14.4 kWh battery packs?  Sometimes referred to as "magic charging" or "voltage sag" or "voltage rebound".
I live in Ireland and there are no dealers, the only one hasn't got the expertise (due to sick leave) to pull the logs and investigate.  So my options are very limited.
It appears that the logs downloaded via the Zero app are very small/recent - about 2,500 entries, and even when the bike is idle only covers a few days.
My next thought was to go a ride to recreate the issues and capture logs frequently... but then I don't know if the App Download can/would demonstrate the problem.

Any thoughts/experiences to share?

Thanks!
Paul.

Hi all,  I had similar issues with my 2020 SRF as those above.  My failure was triggered by the v19 firmware upgrade, replaced under warranty by the dealer, back and forth to trouble shoot and I ended up resolving on my own.   
There’s a thread on this :  https://www.electricmotorcycleforum.com/boards/index.php?topic=10973.msg102112#msg102112

My CCM had to be replaced a 2nd time as the first module wasn’t coded to my unit.  The new module worked at the dealers and then lasted 1 day, after which it only worked when keyed on or on charge.  That lasted 2 more days, after which - nada, “NOT CONNECTED”.  I waited and chased for months but my dealer and Zero country team weren’t interested.

In the end, I disconnected the CCM module completely and removed and replaced the SIM card.  That did the trick.  In future if I ever get a CCM issue again I’ll be doing this first.  It’s really easy to do.  Obviously DON’T if your bike is still under warranty!

This is a good FB article on how to get into the CCM and what it looks like:

Just an update on my own CCM issues / situation.
I tried time and again to prompt the dealer, and Zero UK, I received silence.  I think these units are temperamental and so I suspect there are many root causes to what is the same symptom (no connectivity).
I decided to go in and investigate myself.  I had previously removed the 5v fuse to the CCM with no luck whatsoever.  The bike still reports “Cellular” status as “Not Connected”.  So I proceeded and removed the tank plastics (easily done) and removed the CCM module, which is just behind the ignition switch and secured with cable tied.  I just cut those and then removed the rubber boot that prevents water ingress.  The plastic housing is held closed by a single small screw.  Removing this I can see there is a sim.  I popped this out,  then put it all back together and connected to the bike.
Keying the bike on and the status showed as “Connected”.  I had forgotten to put a little internal plastic cover back on and when I did so it reported “Not Connected”. I took apart and reassembled (all whilst connected to the bike and keyed on) and it flipped to “Connected” again.  Loose wire connections?  Flaky cellular connection?  Unit upside down?  I’ve no idea.  After a few hours the bike is staying in a “Not Connected” state when keyed off and “Connected” when keyed on.  I remember a firmware fix was supposed to resolve loss of connectivity when the bike was off and not charging.   I’ll continue to monitor, fingers crossed I at least have connectivity when it’s charging - that’s the bit I miss; ie when should I go back to the bike if I’m not in Bluetooth range.
