Tidlige elbiler: PSA / Sv: Sirkulasjonspumpe

Hei.

Sliter med dårlig (defekt) sirkulasjonspumpe. Citroen kan levere, men skal ha 3600 kr for ny. Leste her på forumet at flere har benyttet Johnson Pumps (f.eks. denne https://www.seasea.no/cirk-pump-cm10p7-12v-20mm). Den er litt dyr, så jeg lurer på om noen har en pumpe de ønsker å selge?

Og, nå som sirkulasjonspumpa sluttet å "bråke" la jeg merke til en annen lyd. Er det en annen pumpe som går under bilen når tenningen skrus på? Ikke bremsekraftforsterkeren, men en konstant lyd.

User voitric on french forum vehiculeselectriques.fr sells
https://www.docmicro.com/watercooling_pompes-laing_article_11655.html  for 20€+ shipping. Bargain for the quality you get. I bought 3 pcs. so far (for all Saxos and P106 arround me).
Another sound you mentioning is probably from power steering assist. Some are silent but mine has annoying high pitch buzz. I installed switch so I can turn it off.

Don't know if the DC-DC starts, how do I check this?

The fastest way is to turn on cabin light. When you turn ignition on, light should turn brighter. There is little delay, maybe 0.5s. Voltmeter reading should be over 13.4V

P.S. Checkelec or Lexia must connect to ECU. Diagvel or Lexia have ECU diagnostic utility. But I do not think that you have faulty board. Something else is in play, I'm sure.

Everything you said points to multiple failures not related to each other. Occam's razor would put ECU connector as main culprit. Wire brush and contact spray may help.
Have you checked sagembox ECU bay? My car was also not used for a while when I bought it. I found at least 1dcL of (I guess) condensed water inside. Luckily, only light water damage occurred.

//Marin

P.S. Does the DC-DC converter turns on upon ignition?

Most likely, the accelerator pedal calibration data stored in ECU, mismatches the actual pedal values. Try the following - turn the key to start engine position and hold it there. Lightly press accelerator pedal until engine engages. If not, lift pedal (few mm) with your foot underneath. If you're just a bit lucky, car should start.
Without equipment for ECU calibration, you can do potentiometer calibration. Basically, you'll have to change initial position of the potentiometer lever. Just loosen two screws and rotate potentiometer to desired position. Free play is sufficient to find new working position.
Over the time, plastic lever sliding in metal slot wears down thus changing position. It eventually ends up in inability to start the car. Foot lifting trick helps quickly, but permanent solution is "manual re-calibration" and greasing the slot.

Good luck!

Tidlige elbiler: PSA / Sv: Saxo problem
mandag 09. juli 2018, klokken 11:57
(hopefully) Final update:

I have received new chopper board, replaced my (suspectedly failed) one. I started the car and immediately after pressing accelerator, yellow error light appeared. Car would not move. Reason - Permanent fault - Function: drive current chopper.

Before I put my board back in, I took another look at it. And bingo, I found (at least one) error. Zener diode CR37 (6V2) was shorted. I replaced it, put everything back and, voila - car works! :) I have tried to reproduce problem but was not able to. So It seems that the problem is finally resolved.
It was just 02.15h :) so I examined donor board and found mechanical damage. Can someone tell me the component markings for CR46 (diode, probably a zener type)?

Any chance for modifications on older ECU's (3.01)?

Have you calibrated the speeder pedal ?

I don't know how it's done. Does it require dedicated hardware (Elit)?

//Marin

P.S. I have replaced ECU. Little improvement but "false" starts are still present.

1. where are you measuring ? (what is armature voltage ?)
2. Your pictures shows 100hz (50hz dob. rectified) noise .. ?

Wild guess...
Do the controller think the car is running and try to regen bracke ?
What happens if you push the car when you have the failure ?

br.

1. Pictures represent collector voltage
2. Picture should represent PWM voltage delivered to motor.  It looks dirty but I think it is just how digital scope represents too much data on small resolution screen. When time base is reduced, signal is nicer and cleaner, but then you miss those pauses in signal.

I dont think that the car tries to regen brake. I lifted the car and could easily spin wheel in both directions with no apparent resistance.
Pushing the car during error - tried that numerous times. Does not help. Switching between forward and reverse sometimes helps. What really puzzles me is - once started, car runs without problems. Even in drive, switching between drive and regen is OK. The only case when this happens is when the car stops and the motor current is 0. If I apply little throttle just before car fully stops and hold it with handbrake - it will start. So, now I'm driving it like that. No fun there. Waiting at traffic lights with handbrake on and feeding 5A into motor.  :-[

//Marin

P.S. I even replaced speed sensor. No change in behavior.

New update:

Problem resurfaced again, so I'm back to square one. I did some investigation and this is what I found.

DS1Z_QuickPrint4.png


This is the armature voltage when the problem appears (car not moving forward, vibrations felt on sterring wheel and the whole chassis).

DS1Z_QuickPrint6.png


And this is armature voltage when the car starts normally.


I was mislead earlier because I was looking at single signal, rather then full burst.

So at least I think I found root cause. But I still do not know what is causing it. I think I can rule out engine. That only leaves IGBT, chopper board or ECU. Only. :)

I am looking for chopper board for Sagembox Y1000, (early version, without thermal protection).
Why do you want the easly version ??  All cars, regardless of production year, can use Y3000 too.

I was under the impression that Y3000 series uses an extra temperature probe located under charger (the one my early Y1000 misses). Another thing comes to my mind: can ECU version 3.01 be coupled with Y3000?

Update:
After taking motor apart just to find nothing, I did the same with the Sagembox. I took out contactor, chopper board, IGBT, everything! I replaced few of notorious 100uF/50V caps (one leaked a little but measured OK), cleaned all contacts and put everything back up together.

One week and 650km after - not a single "false" start. Even when provoked, the car starts fine. I'm glad that it works but I'm not quite happy for not finding root cause.

What really got me angry and frustrated is fresh reductor oil leak. Previously dry engine is now oil stained. I guess that I didn't tighten inner reductor cover enough.  I soooo don't want to take it down again by myself... :'(

Update:

I finally got the time (and courage  ) to take the motor down and perform the reductor inspection. And what did I found? Nothing!! All gears are in perfect condition. I put the missing pin in one planetary gear shaft but that was it. Case was very clean with no deposit of any kind.


No damage at all!



Sunk shaft (pin missing)


Fixed.






Excitation looks OK, throttle responsiveness is good.

Right now, everything points to collector (90%) or chopper board (10%).
If I'm thinking rationally (may not be the case with everything going on), it is not short circuited wingdings. My guess is that IGBT would fail if that is the case. I have just finished 500km trip (300km high speed highway). Car endured everything without (noticeable) problem. I have even tried to force it to fail - maximum accelerations (red zone wherever possible, in my configuration thats about 30kW into motor)), maximum speed, high speed regen (150A) - nothing. Damn thing just rolls without objections.
If that will be that case (motor collector issue), I'll be very disappointed. I was always very light footed, my average energy consumption is less than 124Wh/km, original brushes replaced after 80kkm (not because of the wear, 4mm left).
Now I'm thinking, what are my options? Motor replacement? Are those used SA13 available at all?

OK,
Then i sounds like the reduction gearbox..
Have you try to take the axles out or check the gearbox oil for metal spoons ?
Br.

I have replaced oil about two months ago after 100kkm. I have not found any metal debris. Oil was dark black but that is normal for the type.
Before taking the motor down, I will check axles. But if I have to chose, I would rather have gearbox issues than gimbals. It seem those are scarce with ludicrous price tag.
