Zero Motorcycles Forum | 2013+ / Re: Rescue a dead DS 2013
« on: July 22, 2019, 12:04:50 AM »
Hmmm what's "wrecked" entail? 
A just "dead" bike could be able to have the 2013 battery recall service if it never had it.  Is it an 11.4 battery or other?
If it had been in a crash I think that would be hard to sell that idea to Zero.  Maybe a 14.4 battery at cost?
I have a 13 DS with 30k miles on it and it's going fine.  The suspension isn't that good but it feels lighter than my 17 DSR.

I see your catch 22 not knowing what else might be wrong with it but "if" it's just the battery (and for sure if you get it replaced for free) you'd have a hell of a steal on that bike.

Good point, wrecked was probably not the right word, it was stolen and then abandoned. No signs of any crash. Yes it's a 11.4 battery but the bike has already been at the workshop as mentioned so I assume they won't get me a new pack. But maybe worth ask Zero directly..

Will charge the pack slightly higher, as 95v might be too close to 0% SoC for the BMS to wake up.

I'm aware of the risk and of course won't resell it. Payed a little over 1000usd for it, https://evea-kartmasters.fr/en/synchronous-motors/1817-me1507-pmsm-brushless-motors.html
It's still able to get registered, I'm fine with lower capacity and power specs compared to original and I prefer to fix used stuff rather than buying new.
I might be able to arrange another power supply than the original battery to try the other parts of the bike out but would require more work.
Please reply here if you got any hints that can bring me forward.

Well I've thought of it but when I took the tank off and saw how it was made, with vertical halves and had no real bottom so I just left it alone.
I had thought of cutting it in half below the "horns" and clam shelling the whole thing with hings at the front.  It wouldn't have held my helmet but the unused horns and side space seemed wasted.
The only thing I'd say is you may need to mold it in such a way as to leave the same air gap over the battery as the OEM tank for heat management.
I guess put a inch or two wood block on top of the battery and see how far that lifts you helmet and mold from there.  The helmet lock attachment at the front of the frame is just begging to be an attachment point as well.

Good luck and keep us posted.

Good thought about the airflow, I got the top of the pack scratched from the bottom of the small original compartment so at least on the 2013, it's not a complete gap, but might be a good idea to not cover it up to much. My idea is to use some kind of water tight fabric in the bottom, seems faster than trying to make something hard to make an precise fit to use all the space.

I found it far easier to just install the rear rack and top box.  If you ever decided to go with the charge tank or the power tank, you'd STILL have the top box to store your helmet.
Thanks for the hint, but I don't like the looks of a box in the back and when I've tried bikes with a rear box it tends to be in the way.

JaimeC let the man with the skill set make something cool (that I can't make on my own).  :)
Annnnd what if he want to store two helmets?

:)

Sent a PM to the thread owner in previously mentioned thread to see if she/he wants to share the 3d model without the tank;

Zero Motorcycles Forum | 2013+ / Rescue a dead DS 2013

I just got to buy a wrecked Zero DS 2013 for about the price of a new Montenergy 1507. Most part seems ok except for dead battery and missing belt. My local zero workshop had a look at it but after an unsuccessful MBB readout they told me it's not worth the effort, which didn't surprise me. Afaik the bike as been standing outdoors for about 3,5 years, probably at 0% SoC from the start.
I still haven't given up but I'm a bit stuck at the moment.
I've opened the front of the monolith battery pack and made a male connector to interface the female connector coming from all the cell groups, (and temp sensors I guess, 29 pins for cell groups and 7 more that I haven't figured out yet). I charged the pack really slowly under careful observation to 95v (started at 1,8v so it was really dead), using a bench supply, which means about 3,3v/cell and then tried to reconnect the BMS and continue charging with the onboard charger but no signs of life at all weather I use the key or charger, not even the BMS led's. I was hoping to get a bunch of error codes to start working on.
I didn't have any tool to measure the capacity at the outputs of the bench supply but at the input it used about 1,3kwh to 95v and the cell groups seems to behave quite similar.

I don't have high expectations from the old pack but even if I'm ending up not being able to use it at all I want to start of by putting the system under power to try the rest of the parts out, and see if the motor is spinning, at least it turns freely. Got some Zoe modules that I thought of retrofitting in the battery case if I have to let go of the Farasis cells.

I've been checking all fuses, tried to reset the BMS (with both buttons) and disconnected the MBB to reset.
I've tested the main contactor separately and it switches on at about 50v, only before I charged the battery though.
Tried to get something out of the uart at the odb but seems dead.
Measured the pins at the com port on the BMS but all seems to be close to 0v


All I've got are:
*Some clicking from the charger relays when plugging in, and then I actually get a slowly rising voltage at the motor controller inputs, up to about 80v while the charged draws about 10w from the mains.
* 95v from battery at pin 18 on the MBB connector 1 (https://zeromanual.com/images/b/b4/ZeroWireDrawing_2013_S_11-4_R-1-3-0_no-grid_highRes.pdf)
* 95v at the 4pin connector leading to the ignition key

Anyone got a clue if there is anything else I can check to get me further?

Zero Motorcycles Forum | 2013+ / Helmet sized frunk mod?
« on: July 21, 2019, 05:39:13 PM »
I've been thinking for some time that it would be nice to be able to have a bit more storage available onboard, preferably large enough for a helmet, so you could keep your helmet dry and a bit safer when parked and to easier bring a 2nd helmet while riding. As there is quite some unused space on top of the battery at the Zero S/DS I'm a bit surprised that I haven't seen anyone doing such a mod yet. Is there anyone else that found someone doing this?
It's quite tight but my Shoei Quest medium could be fitted 2 ways as I see it, and my Shoei RJ Platinum is no problem to fit in between the frame tubes. The fairing needs to be a bit higher than the original though, but not a problem as I see it. Also if you don't have the need for storing a helmet some more space could be used for groceries, chargers or whatever which must be useful for others. My bike is a 2013 DS 11.4 by the way, but afaik the frame has not changed much, if I'm not wrong some later bikes has some plate on top of the battery box, which might interfere with the available space.

I got decent skills in solidworks, fusion and aluminum welding so hopefully something can come out of this idea.

Took some pics while testing the fit, rear facing is probably better, atm the doghouse is uncovered, which allows for a little more room, could probably slightly alter the cover to gain almost as much room but still be protectiv. See the attachments.

Haven't tried but this project seems to do what you're asking for. The readme inclueds a link to the protocol specs.https://github.com/bres55/Smart-BMS-arduino-Reader

Thanks :) Wasn't so much of an achievement though, pretty much plug and play, it's a shame I haven't shared the findings more earlier on. This was 4 years ago, mostly connected to this environment/off grid festival:
https://www.skogsfesten.se/musikkonstworkshops2018

Just had the bike about 6 months before it got stolen, but been trying to do similar things with other electric vehicles, last year we used the 400v bus at a Nissan Leaf connected to a large 48v bank in the back of the stage via 3*3kw Eltek chargers (which worked fine with dc input), then used 48v UPS's to invert to 230v ac for the venue, this setup had less efficiency but allowed for hot-swapping (so we could drain the car, then have some time to go and charge it up again of site). Stumbled upon the stolen Zero a few weeks by coincidence, hopefully I can buy it back from the insurance company and do some more experiments again, battery probably in really bad shape though, seemed to had been sitting outdoors uncharged for 3,5 years :(
I actually also used the Zero-UPS setup in my cottage a couple of times and powered a induction stove, if I remember correctly I could run 2 of 4 zones at about half power. Electricity to heat is usually quite tricky and maybe not the best idea if there are options, consumes a lot;

Sorry for hijacking this thread and sliding OT.

Hehe. You're right, 8s lead-acid off course, my bad.

I've done a similar thing a couple of years ago using a Siemens UPS built for 4s lead-acid batteries so about 96v nominal, if I remember correct the model I used is this; http://www.arifidenza.it/Public/data/ik1xpp/201093133641_a.pdf Siemens Masterguard A Series 3000, which could deliver a decent sine wave at about 2500w continuous. What I also discovered was that the Zero DS 2013 I was using were fine emptying the battery to the inverter instead of the motor controller as long as you gave it a spin (had the rear wheel hanging of the ground) at least once/hour, if not it went in to some kind of standby mode. I used it a couple of times running a small venue with soundsystem, lights, backline and control booth and did not have any problems really.

The picture is from when I first tried it out with some restive dummy loads, the UPS was connected straight to the dc-link at the motor-controller terminals. The nice thing about that specific UPS, more than being one of the few that can handle the Zero voltage span, is that it has quite small transformers, probably high switching speed, so without the default battery it's quite light for the amount of power compared to other UPS's.

Even tried charging a Nissan Leaf a few times with this setup :)

Guess you're already aware, but the zero fx weighs about tiwce as much as the ktm 85

Just interested to hear if you made any progress with the emw12000 and your zero?
