Hope not, at least there were some ways to keep the knowledge safe in a DB for almost nothing or anyway to ask for help to keep maintaining it alive....
Anyway, have you any Idea where to find Battery Diagnostic software and general software for the Empulse?
Thanks

Hello it's a couple of weeks I'm trying to connect to the brammo forum but seems down, I have a 2013 EmpulseR that need care and the forum was really necessary for that. Anyone has any idea why the forum is unaccessible?
Thanks

Yes, of course, and maybe more reliable but less elegant.
I have a nice box made by an endless-sphere member that's for mechanical wire to hall effect, and a lot of potentionemetrs for the Oxygen cargo scooter that are leverage type pot, with an insert on the leverage to hook a standard mechanical wire head onto, I'll post some specs/pics when at home.....it is reliable and interesting, made in UK.

You mean this one ? https://endless-sphere.com/forums/viewtopic.php?f=31&t=58801 5vdc if I recall.

Yes exactly.
The max output is 6VDC and it is adjustable by moving the magnets inside the box.
The Oxygen Cargo Potentiometer, should be the best option for a cable actuating pot, though. It is splashproof, reliable and made for Heavy Duty industrial applications. Shouldn't remember the brand and shouldn't find the specs on my laptop right now, It is certainly in my Shop deskPC and anyway I have them phisically so I'll post an image soon, there are versions with almost any output.....

A left hydro brake lever plus pressure transducer is probably the best performing and elegant solution for fully variable regen, indeed.

Followed closely if not paired with the mechanical potentiometer in a box attached to clutch levers ;)

Mine was just a concept idea, exactly as you describe, not a true varible regen but a switch (I've used the word "multiswitch" before), I've called it "pseudo-variable" for that reason. Eheh! obviously a true variable regen as you use and suggest is way better, but not for everybody......if I will own a Zero, sure I would go with the full variable regen even if that would mean to virtually loose the warranty, but, actually, I have a friend/customer owning a DS and asking for a way to get some extra regen features without the need (and the implicit risk of warranty expiration) to reprogram anything.

Good point about the need for 0 throttle before changes take effect....my feel is that it is true for speed settings but not for regen settings where changes seems to be valid just after a fraction of a second, at least in the 2014DS I've tested recently for some days, but maybe I'm wrong.
Were this the case, pulling/releasing fast the clutch lever, one could luckily pass through all the lever's bands of my switch idea under the limit time, and go directly to the other extreme (from zero neutral to the actual throttle roll back regen and vice-versa) but even, with a bit of use, pull (or release) the lever slowly (band by band) and give it the time to get the relative regen.
There's even to consider that one would pull the regen lever (and get regen or a coasting feeling) mostly while rolling back to 0 throttle or yet there.

I would just like to try that, and maybe the real world would say that's totally wrong and useless.......

After riding this way for a while I am not sure if having a "second" throttle would be easy to use. Even if you capped the voltage range I think when you start to weight your palms from braking forces it might be difficult to adjust your input at the level you can with a clutch.

This might also be said for the vetrix style input ... but since I don't have a vetrix I can't really compare this. However since I haven't seen many complaints about the throttle being hard to adjust for regen upon braking hard I will assume it is a valid option.

Although the patented PWM neg/zero/positive throttle works great and intuitively,  issues with the front brake lever are not uncommon with Vectrix and negative throttling; my buddy who owns one,  has the brake levers swapped, for that exact reason.
 I wouldn't have any negative throttle, nor a second left throttle in a true motorbike...I mean...these could be valid and perfectly working options for some, but that's not my personal feeling.

The hydro clutch concept is my preferred one, but as stated in my last post I would try to almost reverse the concept  with 0 regen at full lever's squeeze, and, through customized regen bands, still maintaining the factory settings while not pulling the lever.

I'm pretty sure, that kind of pseudo varible clutch regen should be achieved even without mods to the controller, and only working at the 12v power line level and with actual buttons and sensors.
I'm sure that using a small, external microcontroller, shouldn't be so hard to get that kind of system only acting with the mode switch and the brake lights......indeed, actually, there are 6 different regen settings in a bike (2 for each of the 3 settings), but you can't freely cycle among them, a microcontroller with some code should do that easy and in a very small box......

Hey Burton

I don't know what kind oftransducer you are actually using, but yes they could suffer from freezing temps, depending on the type and specs of the device. but as you point out these are mostly problems concerning the water ice expansion. I belive that, likely, even in anoil based system, freezing moisture even in the enclosed air could lead to problems with some transducers at freezing temps.

Since me too, I'm working to develop a left (hydraulic clutch) lever for regen, I asked here and there my expert buddies about the best reliable and precision hydraulic device for this application and got the advice to try an industrial sealed pressure transmitter or a crystal type transducer, often devices rated for extremes temp ranges, able to take vibrations and last longer cycles than standard devices, althoug more expensive. Have not really deep-searched about them actually, but just typing on google gives good examples with specs and everything.
It is a very interesting application, and will follow your reports and develops...


A bit OT....^_^

My ICE biased idea for a regen actuator is to work from a clutch lever, maybe an hydro kit like brembo and other makes, even with a racing foldable lever (like these ASVs http://www.htmracing.it/cms/images/foto_prodotti/foto_frizioni/frizioni11.jpg). what would be great, is to use then a sort of multiswitch pressure device allowing the lever to act with bands like:
- from 100% of throw (totally squeezed) to say 85% = 0 regen
- from 85% to 50% of throw = 40% regen
- from 50% to say 15% = full regen
- from 15% of throw to release position =  normal regen (that means the roll back regen settings of your actual mode)

This way the bike could still works exactly in the "factory" way, if you're not touching the lever (and even fold it up), but can give you a -0 regen coast feeling- while squeezing the clutch and a -clutch plates engage feeling- while releasing the lever, till the normal rollback setting you have....

A more electric biased approach could be otherwise a Tesla style twist throttle, that in a motorcycle should give something similar to the engine braking feeling of Big mono or twin ICEs bikes while releasing the throttle partly/fully with slow or fast movements.

Hey guys
just to report that the bike had a failed DC-DC as supposed because of
the problem type, the fact that no kind of error was logged, and finally the fact that plugging the DC-DC connector a little spark was visible/audible with visible signs left on the connector.
Everything was covered by the warranty and the distributor with an 8 days of bike stop for the owner week-end included, not so bad for a very new market like Italy.

would be cool to use the OBD2 style serial interface, and I have TTL chips and OBD plugs to build up the adaptor, but the port has a tiestrip and seems sealed too, so it is one of the parts I would not open.
Thanks again Burton for your great help...so you can confirm that the bluetooth log has different data output form the serial log?
Is any kind of password needed to use it?

J.L.

no I have not the complete wiring scheme, but only the scheme of the 12V after the fuse box.
I know it is different just beacause some of the connectors in the 2014 have a different pin count than in your scheme, Burton.....luckily for the sevocn DCDC would not be the case.....

I have unplugged, cleaned and re-plugged all the connection I was able to reach without disassembling the whole motorbike and nothing has changed.
Looking at the old threads about similar problems (that was in a 2012/2013 bike) it seems that the MBB and/or DCDC have been the defected parts  >:(.
Honestly I would not open sealed parts or make any non fully reversible action in a bike that is under warranty....I am not an authorized shop, nor the owner......I just want to figure out the possible problems and help that buddy to have this funbike fully functional again (if it was an ignition or connection or discontinuity problem), possibly learning a bit about it, cause I fully support the electric revolution and I work in one of the few shops if not the only one in my area that offers EV services. Unfortunately there is not a critical mass of Zeros actually here....otherwise I would have contacted Zero directly to know if it were possible to be an authorized service shop not being a dealer, as it is for most vehicles....

wow, you guys are really fast  8)
Thanks Burton for the Diagram and the reply ;).
I am sure the ignition is Ok because I have some of the same ZADI ignitions as spares that I use for the Oxygen Cargo e-scooter fleet that I work with, and ZADI is a local (Italian) manufacturer,  so I have tested the zero ignition on an Oxygen electric cargo scooter  and one of the brand new I have on the Zero and everything is OK. Also, Having the Ignition disconnected the problem is still present.
Plus there is the question that the main contactor is not affected by the problem so the bike is not able to run without the key, in the dispaly, only the backlight is still on . when you turn the key than the contactor acts and the bike works perfectly.
I will try to check directly the pins you suggested, I should say, however, that the 2014 wiring diagram differs a bit from what the 2013 was from your scheme, Burton, but I should be able to identify the right backwires where to put the tester on.
would like to know how to look at the .bin file by myself if it is possible.....
I will post that file, even with some pics.....
Thanks Again

Hey guys
A friend of mine has a 2014 DS. It is an ex demo of a local dealer.
It has the described problem of not turning off the 12v line, so actually the only way to get it off is to remove the fuses, or the DCDC main fuse.
Other than that the bike is fully functionally without any kind of othte issues.
Actually the owner is waiting for the bike to go to the dealer shop, but, since they are a bit slow organizing the 300miles transport, and I am a bit familiar with LEVs He asked my opinion and left the bike to my shop asking for my ideas on that issue, and I accepted mostly to have the oportunity to live learn about this amazing bike, and maybe help, and obviously even to try the bike.
The ignition works properly and the problem is still present disconnecting the ignition.
continuity seems OK.
I got a some blocks diagrams about the 12v power line and downloaded the 2013 scheme here on the forum (a damn cool work, indeed), but I concluded that the DCDC should be the responsible.
Have you guys any advice for things to check or look at?
the bluetooth app shows no error or warning messages.
I have downloaded the log but bet is not useful.

I will appreciate your suggestions.

Cheers

J.L.
