Hello everyone.
Mi name is Fernando. Im from Spain, but im living in Norway.
Im trying to help a friend, that have a little cargo Fiat Fiorinno converted from Micro Vett.
The car is from 2012, with a 94V Engine and a Lithium battery pack. Im not sure about the capacity but i can try to find it on the documentation of the car. The owner says that he can make around 80 km in winter time here in Norway ( West side, so from 5 to -5ºc not less ).
To warm the car, is instaled a Diesel Webasto system :mad:. Yes, its not so green.
So, The Problem:
The car is not charging the batteryes.

What happened?
He told me, he was driving like a normal working day, and he reach the office with around 25% percent battery left. So he pluged in the car to have it ready for the next day.
The next morning he removed the charging wire, and the outside led indicator was in a fix green light, that means the car is fully charged. ( Blinking orange/red when charging ).
But inside the car, the battery level in the instrumental panel was 25 % yet.
He drove for a while with this battery power until the battery was completly emty... :( Yes, not a good idea...
After that, the car has been stooped for a long time, and now i has take the chance to try to started again...

What i have done:
Off course, i have been try to plug in the car to see if its was charging, and off course, is not. The same problem, when start to check, it says the battery is full ( according the external information that you can read in the chargers inside the motor compartiment. ) But in the instrument panel, it says is completly empty.
I have checked the battery charger, and it has some rust in one connector, so maybe it was wet for a few time.
The plastic cover that usually mount down the engine in a normal car, is not there, so maybe it was so much water jumping over the charger...

What i think:
1º The charger is not working
or
2º Some problem with some battery cell (3.2v cells i think)

Any other idea?

About the charger:
Its nothing writen on the box, but inside i can read that the motheboard is a Zivan ZR70F, and the box looks like Zivan NG5 ( this one is 230V monophase )
Somebody can tell me how to check this box?, just to confirm if is working property or i must check the batteryes...
I know its possible to check it with the pc, but i have no idea where find the software and how to use it.
Any information will be really appreciated.
Sorry for this boring text...
Thanks so much.

Hi
I came across your Micro Vett issue ans was wondering how you managed to solve the problem. I am facing a simular problem On our MV 500E (same technology). I found these pc connectors but on a terminal ist does not show any output.
I am looking forward to hear from you.
Regards
Andre

Hi, i couldn´t do so much for the car, but i will tell you everything i found about the car.

I contacted with MicroVett in Italy, and in the first moments looks like they will provide me support by telephone, but after a several calls, and promises to help in other moment becouse they were busy, finally they told me that they can not help by phone. So they provide to me two options:
1º Send the car to Italy and cotize the value of the damages
2º Send to Norway a Ingenieer to check the car.
In both cases, we must pay all expenses, to send the car or tickets and hotel for the personel.
Of course we refuse that, becose that suposed spend a lot of money only to identify the problem.

Making some researchs i found a guy in England that has experience with those cars, so i contacted with him by email.
I sended him a rapport with the battery status, and he found that a few battery cells was in a very low level.
So, the firs problem was:
The BMS ( Battery Magnament System ), was detecting the very low charge in those cells, and was cutting the power from the battery and not allowing the charging procees. All as a security protocolls.
This expert recomended to change all the battery packages, becose the system can be compromised. He told me than the price can round 90.000 Norwegian Kroners :eek:.
That was a lot of money, but then we had another question. It was "only" a battery problem?, was the charger working?
Then he talked about overide those protocols and force the charge of the cells. That will provide me the posibility to know if the charger was really working.
Sounds good, but again he said that he couldn´t do it over my computer working online. He must come and use his own. And of course, we must pay all expenses. Again, to much only to check the final price.
Then, i found the BMS manufacturer in Italy, and i contacted with them. After expose my problem, i told them that i really need to check before the parts that were working and what musted be remplaced before decide the viability to fix the car.
Again at first moment they agree to help me sending the codes to activate the charging procees by email. But the next day they send me a email telling me that the administration offices do not allow to provide me the information for security reasons... ( of course, you can force the system to charge all times an overload the cells. They don´t wont to take that risk ).
So after lost a lot of hours looking for a solution:
1º I don´t know really if the charger is working.
2º The battery can not be charged, so the cells must be in really bad conditions now.
3º One of the suppliers, ( i don´t remember ho was ) told me that MicroVett was in bankrupt, but in other place i readed that they were trying to refloat the company again.
4º I found that is a company in Geman that is manufacturing the Fiat 500e, but i don´t know if is the same system. The name is Karabag.
5º About the charger i couldn´t take so much information also, becouse the one used on the fiorinno is a special variant of the Zivan NG5, and was designed specialy for MicroVett, and again is not any support for it.
6º I asked to MicroVett for the Workshop manual, and they refused to send it to me...

My personal opinion:

I will not fix the car for those prices, with no garanties. They said you will have. But looking all those problems, i will not take risks.
Maybe a good solution can be rebuild it with customs parts, like find your own battery charger, your BMS and your battery cells. Then at least you will be able to identify the problems and fix the car for your self.

But, that was the problem of this car. Maybe you are lucky and its only the charger. Check your battery status, you need to have a Serial cable. I can provide you the comands i have to check it. I dont know if will work with your model, but you choose if want to try.
Try to contact MicroVett, Karabag or a electric vehicles specialist to see your posibilities.

Good Luck and tell me if i can do something more for you.
I remember i feel so lonely when i was trying to find the solution... ;)

Hi Netnanocom
Sorry nobody answerred you before
you should have posted a few more "help me" comments

Anyway
Where exactly are you?
You should give your location with a request for anybody local to help you

They won't be able to check the programming but somebody who has a good idea how these things work and a multimeter should be able to ties down what is wrong

So
Anybody local ????

Hi, thank you soo much for taking the time to send an answer. I fully understand your lonely feeling: in Switzerland there is zero support for this car. I was always very happy with the car until it stopped working. Karabag sold these cars but now they have their own variant.

Micro Vett in Italy is still active in a smaller form after the bankrupt. They still rebuilt Fiat cars to Electric but with another technique.

Can you tell me something more about the way to connect the car to the computer and to read information from it? I have a serial cable (should it be a null-modem, crosscable?) What terminal software should I use?

I hope I will get this car to work again and will share any information with you if I get any news on this topic. I found out the cells are manufactured by Kokam and are still availlable (even the complete units containing 30 cells). The problem is that they are way too expensive.

Hi, thanks for your reply.
I have a multimeter, and i check that the charger was not working.
But, i can´t know if is for a charger defect or is becouse the BMS is not allowing. I suposed that is the BMS who is stoping the charge, becouse the battery status. But, what was before?
- The charger do not worked, and after some time some cells went low.
- Or one cell or some had a deffect and the BMS cuted current. And after some time other cells went bad also.
This i belive is easy to check with some support from the manufacturer, like you can do with any other normal car with a OBDII protocol. But not any rasoneable option from them.
After that time and with this wheather, the battery must be really bad, so i belive i must change it, but what about the charger.
And the worst part, this car is CAN-Bus, that means that all systems are talking, sending and reciving information. In case i use another charger, bms or battery. How to manage to operate if i can not reach the configuration?.
Its here a good Hacker to access to the system... :)?

Hi, it is ironically that I also get one Fiorino to work with in last week. What I find about this car is that it has 260 volt battery and I think 20 Ah EIG cells. They are 4.15 V max (3.65 nom) cells and I suspect that it is 62S5P battery pack.
I think you can start from here, measure pack voltage, but after all you anyway will be forced to disassembling battery for diagnosis. Make photos for us pls.

The terminal software is Teraterm.
The cable that i used is a Serial/USB, i have it at home, so i can check it later. I will try to read the information again and make some pictures for you.
Where did you find the batterys?
Another option was dismount all batteries, find the cells with low voltage and try to recover them one by one with one external power supply. After that, with all cells beetwen "normal" voltages, the BMS must work normaly.
But again, that is easyer with the workshop manual, and go directly to the correct battery, instead desmount all of them to check cells one by one...
I can not untherstand why they don´t provide any information if they are no longer using the same systems.
Will try to upload the pictures later or tomorrow Sipit.
Thank for the information Berlinger, i have the car parked outside and fully mounted again. But now it looks like is coming some more information, so maybe if we get some more help, and more information, i can try to fix it again. Then i will dismount it and upload pictures with all the process...
:rolleyes:

Thanks, that is great. I am very anxious to see if I can get any info out of the car.

I opened the battery chassis and found a number on the cell that is on top: 70460330. One chassis contains 30 LiIon cells, 3.7 volt 100A. The chassis is called SLBP70460330-30S1P. The brand is Kokam from Korea. I also came across a chinese manufacturer that could deliver exact the same cells, this company is called AET (=Shenzen Auto-Energy Technology Ltd.)

Replacing 60 cells (The 500 has two chassis) is an expensive hobby and even if you do this there is a very good chance that the BMS will still not work because it might need some initializing or whatever.

If nothing is going to work, it maybe possible to change BMS, Charger and invertor for something accessible.

Hello!
I just become an owner of an Fiorino electric my self. Model year 2011.
Just as described here it does not take charge.

But I did see a guy recovering old 0 Volt lithium cells. They are normally considered to be bad, and not possible to charge. And I have read about people trying to charge them with absolutely no success.
But the guy succeeding bringing 0 Volt cells back to life (18650 cells), he started with a very low current. Only a few mA until the cell came up to 3,x Volt, and then he charged them normally.

I did see "berlinger" write:
"Hi, it is ironically that I also get one Fiorino to work with in last week. What I find about this car is that it has 260 volt battery and I think 20 Ah EIG cells. They are 4.15 V max (3.65 nom) cells and I suspect that it is 62S5P battery pack.
I think you can start from here, measure pack voltage, but after all you anyway will be forced to disassembling battery for diagnosis. Make photos for us pls."

I did measure my car and it has 250 Volt in the pack.
250/62=4,03V /cell. So in one way it looks okey...
But I will see if I can find a suitable power supply and charge it a bit manually anyway. And maybe "it" will come alive again.

Or I will try something else if some one has any new input for this thread.
Me and my car lives in Sweden.

Hello,

could you fix your cars? I would also like to take a look on a Fiat Doblo which also does not take charge. The owner is selling it pretty cheap and I am not sure if a repair is possible. Is replacing the broken cell possible?

Can you please post the commands you have send to the car to get some diagnostic output?

I have done some more troubleshooting:

The car ha 90 x 100Ah LiPo cells.

When turning on the car I get 365V from the battery. So each cell sems to have 4.05V. On the serial interface I see the following log:

Code:
FW Version EXT_I.4.7.1.DB.MUX--Protocollo Esteso


Inizializzazione....
Inizializzazione....

Veicolo in Blocco:
        Ricaricare!
After a few seconds I hear a clicking - I think it comes from the battery packs - and the battery gets disconnected and I am getting 0V on the output.

When trying to charge the car all the fans get turned on. Also the fans from the charger. The voltage is also 365V. After a few seconds I hear the clicking and everything gets turned off. This is from the serial console:

Code:
FW Version EXT_I.4.7.1.DB.MUX--Protocollo Esteso


Inizializzazione....
Inizializzazione....
OK!
Trasmettere t per ottenere lo stato delle tensioni.
Trasmettere config per entrare in Configuration Mode.
For me it looks like the electronics inside the battery pack is disconnecting the batter after a few seconds.

And ideas?

I am working on a Fiat Doblo 2009.

The serial port is cable by near the 12V battery.

I got some more information from the BMS by pressing t / i / c:

The batteries have a max drift of 0.139V. I beleave this is why the BMS shuts down and asks for a charge to get the batteries balanced out.

I also did some more tests with the charger. There is an cable connected to the AUX port. This is the "AC Power connected" signal. When short cut the cable without having the charger connected to DC and AC the car behaves the same like with AC power connected. And the BMS shuts down after a few seconds.

So I think that my charger is broken. I will disasseble it next. But it's a larger task as the whole from of the car must be disassemled to get access to it.

Maybe the cells are just different condition, some are better and some are worse? Do you know what is the voltage range of these cells? For me it looks like the battery is full with about 4 volts cells. Maybe it is just the difference between the cells that is shutting the car down. Maybe the BMS (battery management system) is programmed with a certain amount of allowed variation between the cells. What do you think?

Also you have one cell "Potenze dissipate" (what is it) with different values than the rest. PI-2 value is zero and the other cells are 1.xxx.
00-00-b6-fd .003 1.208 | .000 .000 | .003 1.202

And there is also another with PI-3 = 0

Lot of N.C. on the voltage list too at the right columns. Is it "not classified"

Did you already buy the car? I have same kind of car coming, there is an unknown problem with it :)

Yes I think it too.

I have no idea what this means. 00-00-b6-fb has the lowest voltage.

I think that this are temperature sensors. And N.C. means "not connected". But I am not sure.

Yes, I have already purchased this car and trying to fix it. On my car I suspect the charger to be broken. But it's not so easy to get access to it. I must disassemble the half front of the car... Need to remove last 4 screws which are really hard to access. Hopefully I will have the charger out of the car tomorrow.

What country are you from?

I am from Finland. Do you know if it is possible to charge with one phase only? And do you know the max current of 3 phase charging? Is it 16 amps? And also do you have a charging cable with one phase only? Which phase is connected? I have currently no documentation at all. There were no charging cables or they are missing...

Ok, I am from germany.

You need 3 phases with 16A to charge it. 1 phase will not work. It will charge with 7kw max (according to the documentaion).

I am not sure if you need any "control" electrics in the charger like OpenEVSE for the doblo, but it looks like it will even charge without it.

I have got my charger connector from here: http://www.elektrofahrzeug-umbau.de/shop/ladedosen/

I have just connected the 3 phases + N + PE to it and a 3 phase switch to the charging box. The car starts the charging mode when I put power on it.

As I have a free official EV charger a few km from me I have also tried charging the car there. It behaves exactly the same like with my self make box at home.
