Pin-Verbindungen vom Hauptbedienfeld zum Ladegerät.

Hallo, könnte uns jemand bei Problemen mit einem Twizy helfen?
Ladegerät funktioniert und es kommt die richtige Spannung heraus
das Ladegerät.
aber aus irgendeinem Grund wird es nicht berechnet.
12 Volt Batterie ist in Ordnung.

Ich muss die Pin-Verbindungen vom Hauptbedienfeld zum Ladegerät kennen. da ich das auto nicht habe.
Ich versuche, das Ladegerät außerhalb des Autos zu testen, um es zu reparieren. wenn möglich.

Könnte mir jemand sagen, welche Farbe die Stecker haben.
und poste ein Foto für uns.

könnte uns auch jemand sagen, wo sich die bcb-platine befindet
oder das Leistungsrelais.

versuchen, eine gute Werkstatt zu finden, die manuel würde
Zeigen Sie uns die Kabelbaumanschlüsse und Schaltpläne.
Wenn jemand ein offizielles Reparaturhandbuch hat, möchte ich es kaufen.


Dankeschön



hello could somebody help us out with a issues i got with a twizy
charger unit it working and the correct voltage is coming out of
the charger unit.
but for some reason it wont charge.
12volt battery checks out fine.

i need to know the pin connections from the main control head panel to the charger unit. as i do not have the car.
im trying to test the charger unit outside the car to repair it. if possible.

could anyone tell me what the pin connectors colour are.
and post a photo for us.

also could somebody tell us where the location of the bcb board is
or the power relay.

trying to find a good workshop Manuel that would
show us the wiring harness connections and schematics.
if anyone got a official repair Manuel i would like to purchase it.


thank you

where do you come from?

if only 12V charging is broken, you're little lucky. No way to repair this, bus you can use an extern dc-dc to charge the 12V battery.

hallo danke für die antwort im aus england gibt es nicht viel informationen zur reparatur des twizy hier zur reparatur
das Hauptladesystem.
nur, außer es direkt an Renault zurück zu bringen.

Diese Einheiten können als eigenständiges System repariert werden.
brauche aber mehr informationen dazu

Ich beschreibe, was ich bis jetzt getan habe.

Ich kenne die 12-Volt-Batterie, die voll aufgeladen sein muss, damit das Relais-Ladesystem funktioniert.

aber weil ich nicht das Auto habe, um einen vollständigen Test zu machen.

Das Ladegerät ist an einen Prüfstand und eine Reihe normaler Batterien angeschlossen
Ich kann die aus dem Ladegerät kommende Spannung überwachen
Das ist die richtige Spannung zum Laden.
Das Hauptsystem funktioniert also

Sobald das Gerät wieder im Auto ist, tritt das Ladesystem überhaupt nicht mehr auf, um die Hauptbatterie aufzuladen

also gibt es irgendwo einen anderen Fehler im Auto, der das Aufladen verhindert
Aber ich möchte zunächst sicherstellen, dass.
Der nächste Schritt ist daher, diese Ladegeräte nach Möglichkeit als eigenständiges System zu testen.
Ich möchte vom Hauptbedienfeld des Autos zum Hauptladesystem aufsteigen

Aber ich brauche Hilfe, um zu wissen, wie die Pinbelegung des Steuerkabels aussieht.
Das geht vom Hauptbedienfeld des Autos zum Ladegerät

Ich denke auch, dass die Hauptprobleme mit dem BMS-Board sein könnten
Aber brauche ich das auch, um das Gerät als Standalone zu testen?

wenn irgendein mitglied uns aushelfen möchte und auch irgendein schema
Es macht mir nichts aus, dafür zu bezahlen.

Ich kann mehr ins Detail gehen, wenn es helfen wird, dies zu lösen
mit allen twizy Ladegeräten.
durch Reverse Engineering.


hello thank you for the reply im from England there not much information on repairing the twizy here for repairing
the main charger system.
only except taking it back to Renault direct.

these units can be repaired as a standalone system.
but need more information in doing so

i describe what i have done up to now.

i know about the 12 volt battery that has to be full charge for the relay charger system to kick in.

but because i don't have the car to do a fully test.

the charger unit is connected up to a test bench and a bank of normal batteries
i can monitor the voltage coming out of the charger unit
which is correct voltage for charging.
so the main system is working

but once the unit goes back into the car the charger system does not kick at all to charge the main battery

so somewhere there another fault possible inside the car stopping it from charging
but i like to make sure first.
so the next step is to try and test these charger units as a standalone system if possible.
i want to make a lead up from the main control panel of the car to the main charger system

but i need help in knowing what the pin layout connections are for the control cable.
that goes from the main control panel of the car to the charger unit

im also thinking that the main issues could be with the BMS board
but do i need this also for testing the unit as standalone

if any member would like to help us out and also any schematic
i dont mind paying for it.

i can go into more details if it will help to solve this
with all twizy chargers.
by reverse engineering it.

there is always a way to repair these units

we already repaired this twizy charger
but having another unknown issue with it

Reverse engineering

with more information this can be done


thank you

Hi.

Nope, this Problem has a long History, and sadly there is no known repaired Charger at all. 1 or 2 had just connectionprobs, but all of those with blown main Circuits/MOSFETS are not functual after replace the worn Parts. There is imho somekind of recognition in the Firmware that knows about the break, and shuts down the whole thing.
And there was a high amount of Manpower and Time involved to repair the damn things, but even verry skilled Engineers and Softwareguys couldnt do anything.

Es gibt mehr als nur das Ändern von Fets. Es gibt 1 x 2 mm Widerstände, vielleicht auch 5 Dioden
Wenn Fets blasen, können sie andere Teile mitnehmen. Und wenn der komplette Fehler nicht behoben wurde. Dann schaltet der Rückkopplungsschutz ihn ab.
Aber sobald der vollständige Fehler gefunden und behoben ist, sollte der Rückkopplungsschutz nicht aufhören zu funktionieren. Die Twizzy-Einheiten haben ungefähr 7 Optokoppler, die das System überwachen .




There is more to it than just changing fets..there are 1x2mm resistors maybe 5 also diodes
When fets blow they can take other parts with them ..and if the complete fault has not been repaired ..then feedback protection will shut it down..
But once the full fault is found and repaired correctly ..then the feedback protection should not stop it working....The Twizzy units have around 7 opto couplers that monitor the system and if they don;t get correct switch on then no go.

Yupp, but we ( Friend of mine is a _very_ skilled Electronic Engineer, working in a Laboratory with an incredible amount of Tools and Testsystems..., another one is High Frequency engineer, and my Brother was working with tech-like High-end Amplifiers... ) checked almost every part of the Charger - all Komponents looked fine - no running System...

A lot of People here tryed to fix the damned thing... no success at all.
Another Member of the Forum instructed a prof repaircompany - after weeks they quited the Job with no result at all.

Was nicht heißt, das es nicht geht. Vllt hat er was neues rausgefunden...

Which wiring do you need exactly? I'll show you. I don't think this is a BMS issue. Is the Charger (externally) starting charging without CAN Messages from the BMS? Really?

I’m testing this unit as a standalone unit...no car or no control cable because it is a multi connection to all car functions...my aim is to isolate the the connections required to switch on the canbus and volts with out the multi cable that goes from the control head in the car that has 24pins and goes to the 12pin Twizzy charger ..many of these connections are not required to switch the bus/volts on

I need to first know when ignition switched on it will pass a logic H/L to microprocessor pcb on the charger..what are first these connections at the 12pin charger
.
I’m a reverse Engineer that starts with nothing only data and builds all received data into a effective repair system....I have already spent many hours working out this system indepth via the protection circuits and all the 6 optocouplers...I have also all component fet/smd values needed in case of burn up/blowout.... I have logged many data/volts lines for resistance ...always needed from a know good systems.
I’m sure I have the knowledge to repair this system ...I have already cracked the mains trip fault and then have it working with 58v at the output relay ..but of course with no coil switch on because no system control from the I/O input/output cable 12-24pin.

Hi.

You asked in the "Repair manual" thread about the known issues with the charger... Stromkreisparadies listed a few, here are the ones i know about..

Faulty soldering points at the Main/Riserconection
Faulty conductor tracs because of vibrations and/or corrosion

There was imho one charger with these probs repaired succesfully ...

Main Problem at the Gen1 Charger was the overheating, "fixed" by Renault because of reduced max. Output...
There is a plastic rod holding the cooling Plate tight to the heatspreading Foil, and in this rod there are Nuts which are melting through and so the proper assembly is gone, the FETs are overheating and Bam...

We stopped our search after checking almost every Part of the Hardware (which is a pain in the ass because of these fuc... Glue all over the board...), but had no further interest to "wireshark" aka decoding the charger-internal Firmwarecomunication, cause the Guys had to work for a living... and spended almost several days anyway...

So, if you are the Hacker/rev-engineering God you seem, we all will be verry thankfull if you can solve these Prob..

But anyway, most of the Forummembers have no electronic skills at all, so all repair options are limited, and i guess nobody will be able to fix these chargers for an resonable price. You have to compete with some 900€ for a brandnew charger, coming with new waranty and stuff....

Maybe there is an interest in repair/pimp these chargers to build new, reenforced ones with more power or even couple some of them for a fast-loading System.

I for myself bought me a used charger for 1200 bucks, comming with a nearly komplete but crashed Twizy around...
So i have plenty of Spareparts and sold a few of them, reducing the costs to zero...

Main goal should be imho to replace the complete charging system wit a "fake comunication device" such as an propper Raspberry or similar Microcomp based Device, making it possible to use almost every charger with the corect voltagerange. That will be verry usefull, cause one day Renault will stopp producing/selling the original one...
