Oh. Don wants to argue with Stephane.

Hi - Germany here.
Standard parts are an issue here as well, as Beauceron was reporting. However if your dealer puts some pressure things might work out differently. I have an Experia.

Positive examples:
- Hand brake lever - 2 weeks
- windshield guide rails (structural parts that run behind the dashboard cover) - 3 weeks
- front fork (seals leaking, no seals as spares available, warranty replacement) - 5 weeks
- hand wind protection - 2 weeks
Negative examples:
- main center stand - forever. Contact at Energica says apart from prototypes no serial center stand has ever been build & shipped

Now my bike has been picked up from the dealer and is at Energica/Modena for warranty repair as diagnosis & repair of sudden shut downs resulting from „low battery / recharge“ at well above 60%SOC… lets see it this is being delayed due to part shortage…

When pack are deffective ( at the cell module level) it can be:

1 - All cell internal resistance are  high = no more usable due to voltage sag too low under load
2 - Magic charge = one or more cell have connection problem in serie ( bad crimp between cells tab) = making voltage sag under load to one or more cells
3 - One or more cell having high internal resistance  = voltage sag anyway which also make the BMS to shut down the power prematurely


for 1, your pack is pretty DEAD
for 2: It is possible to  open the pack and re-crimp or spotweld  the bad cell connection with couple hours labor and patience and care.. but you will have to dig the potting manually without puncturing the cell below. I did it when i reconfigured a ZF2.5 brick into a 51V module for my nefew 's electric ATV. The battery was a situation 1 where all cells were too high internal resistance, but spliting the connection into two seperate groups of 14s in parallel made enough power to get about 2.2kWh out of it and make his mini electric ATV to go 90km ;)

For 3, It is possible to solve the single cell internal resistance problem by paralleling another high C current  low capacity cells to it to rematch to the other cells the internal resistance  and have all internal resistance the same again.  I am making it for a Long brick ZF7.2 that I use as range extender on my 2017 SR. The problem is that the cell group no 17 always charge higher voltage than the rest and always sag lower voltage than the rest under load. My plan is to measure the actual internal resistance of the deffective cell group no 17 and to measure the internal resistance of all other cells and to match the calcualted internal resistance to put in parallel to the problematic  cell. I think that this job really worth if it can save a 7.2kwh battery that already fit in a ZERO if it can cost let say 100$ in material and 4-5 hours of work.. maybe more

So what it involve:
- Measure all the cells internal resistance ( 28 total) by applying a load to the pack direct terminal ( before the contactor), using a 500w or 300W light bulb and measure all the cells voltages with and without the load.
- Find the deffective one that have higher internal resistance than the rest
- Calculate the resistance of the cell to parallel to it to make it having the same internal resistance than the rest ( https://www.allaboutcircuits.com/tools/parallel-resistance-calculator/)
- Open the long brick aluminum sheet that is hardly stick to the putting material inside
- Find the location of the deffective cell  tabs under the semi transparent potting
- Dig with cutter, exacto and grip carefully until you reach the metal tabs
- Unfold the crimped tab
- Solder connections to it and take care to not transfer too much heat to the tabs... or drill a horizontal hole thru the crimped tab and install wires with terminal and screw
- extend these wires outside the pack,
- Connect a permanent high current ( high C rate) NMC chemistry cells
- Redo the load test with the bulb and make sure the voltage sag of all celsl are now the same. If not adjust the cell capacity or C-rate until getting uniform Internal Resistacne on all the channels 

IMPORTANT: YOU MUST HAVE A MINIMUM OF BATTERY DIY SKILL TO MAKE THAT.


I made a video to explain the concept in french but you can use the auto translate as well.

I have my SR 2017 ( I bought it new in July 2017)

And I was NEVER able to update it yet. I tried many times over the 7 last years without any succes, New gen app or old gen app.

But guess what??  IT WORK LIKE A CHARM since the begining.. and it dont realy need any update so I realy dont care about remaining to the old original Firmware. It work perfect and i can recahrge my battery at t13é2kW during 1005 time and I can still do 230km with a single charge since the begining!

So.. I really dong give a f*** about the firmware update.. I really thing it woudl just make it running all sort of problems.. si when it work... Just dont touch it!! ;)

Doc
Were you aware that your first update MUST be done at a Zero dealer?  After that, you can do all the updates yourself.


I think the same thing is happening again, that the first update needs to be done at dealer because of the new app.


But yeah, if all seems to be working fine, why bother?  Probably it's mainly about the shop making a little money on electric motorcycle service, since they cannot do engine oil changes on Zeros and need to make up for that. So they change the FW version once in awhile . . .

Fortunately I have not seen any of these sort of issues, in fact they look forward to me showing up.  They get a real blast out of seeing the bike fly up behind someone on the track and hear it whizzing by like a space ship I've been called before.

Just for peace of mind, this is something I might want to self invest in, at least the blanket, and tell them if I ever wreck this thing really bad, just throw it out in the middle of the field, throw this blanket over it and I'll arrange to get it picked up.

I bring my own fast charger to the track, but have it toned WAYYYY down to only do 50 amps out of the Nema 14=50 that is available there.  The wiring there is outside and old as shit, not in the best shape.  I wonder if they'd let me set up a station to fast charge and hard wire it etc.  Supposedly this summer they are getting some of their power redone, maybe I can work with someone at the same time to get me a 100 amp station set up :D

Cool, nice to know there are others in the area.  Now that racing / track season is taming down in florida a bit, Ill have to kick the welder in the ass to make my rack for the top of the trailer and get my stuff going.  Robling and Carolina Motorpark, here I come,  and Taledega and and and... :D

Stealth camping sprinter van. Just put hard hat and hi-vis jackets in the front seats and you can park anywhere!

That's kind of funny, I was driving home from the race track today and someone was trailering 2 Experia's behind what looked like a converted like cargo van.  They were heading towards jax, but we were a ways out so they could have turned off at any spot to go elsewhere.  Really wish I knew where they were from as it'd be nice to find other E bikers around.

The charging does make it a pain for all the EV's, and the economy going to shit and talks of a world war / civil war absolutely are NOT helping any sales or service.

You mentioned going to a tesla type sales model, where you order it direct and kind of cut out the dealers but they will still need service, software updates, some warranty work, stuff like that.  Still going to need someone to do maintenance on them.   Tesla has shops all over to fix stuff don't they?  Energica not so much, and it's appearing the rest of the e bikers, not so much either anymore.

Hopefully things settle down soon because right now nobody can really afford big loans, the banks are NOT giving out loans to less than almost perfect people for what they essentially will consider to be a 'toy'.  and the ones who can afford them, have already got their toys or are running scared too to see what is going to happen.

All this shit, China war, EMP taking down the grid,frying your bike / car. bla bla woof...that shit adds up to drive people away.

That was likely Rick and his wife, they picked up the first two Experias in the US at the CA HQ and rode them back to FL.  I know they have some sort of Sprinter for camping and trailer the bikes for destination riding.

Do I have a battery issue?

No, you do not have a battery issue.

After a full charge, you have to get back into a discharge state to best serve ALL cells, so ride bike and burn-off 5-10% for cells to start their balance session from a normal charging transition where only a few low capacity cells have thier high-side cut-off activated versus a majority of the pack having to self-discharge...that's why it seems nothing has happened...

Repeat steps, betcha after the third iteration it will read 99-100%.
