Hello!

I have a MICRO-VETT FIORINO ELETTRICO 2014 workshop and the car is not working. Unfortunately, I don't have much information about this car yet, because there is little information about this car in our databases. The dashboard has a BMS error and Fuel Cut Off message.
On external inspection I found a faulty relay under the hood. Can anyone specify what the function of this relay is?

Hi, what is the initial problem of the Micro Vett you have? Fuel cut-off can also happen when the voltage of the battery is too low. Have you tried to start it?

The car came to the workshop because the seat heating switch had to be replaced. I replaced the switch and tested whether the seat heaters were working (ignition on). Then for a moment the ABS light and the Airbag light went on in the dashboard. When I tried to start the car, there was a Fuel Cut Off and BMS error in the dashboard.
I also thought the 12v battery was bad (tested and the battery was bad) and replaced it with a new one but the result is the same.

You have to close the door and press the brake pedal before starting. Try that!

I'm the owner of the car. The car is now 2 months in the workshop with no improvement. I'll try to elaborate the situation a bit more.

I took the car to workshop to fix seat heating. During the repair the car's 12V battery got drained (I guess the car was not started properly and the main battery -> 12V battery charger didn't run). Thus it behaved as usual when 12V battery gets drained - ABS and Airbag sign lights up and then it powered off due to low voltage.

The 12V battery got disconnected, recharged, eventually replaced with a brand new 12V battery. It didn't help.

Now when trying to start as usual (charging cable disconnected, doors closed, pushing break pedal, turning the ignition for 4+ seconds), the dashboard displays "BMS error" and "Fuel Cut Off" messages. A relay clicks also, I guess the one disconnecting the Battery.

When connecting a serial cable to the BMS and starting the car, it keeps spamming:
Inizializzazione...
Inizializzazione...
Inizializzazione...
Inizializzazione...

It does not react to any commands sent that usually display cell voltages.

(The text output was somewhat garbled, probably because of bad USB-serial cable, it went worse the longer I tried)

Tried to leave it charging overnight. Still same.

So seems the BMS cannot finish initialization for some reason. Any suggestions what to check?

Is the charger of Fiorino good? I needed to replace it. My fiorino stood for many months. There were similar phenomena. One cell showed 0 voltage.
New charger and wrong cell was charged alone.
Th car run now. The service : https://www.facebook.com/e.service.solymar/posts/2770727043023599

Hi all.
Does anyone know how to change configuration?
Now it is configed to 6 packs (48 UB number, 6*8=48), but I need to be running on 9 packs (9*8=72) if I think correctly.

When I connect 9 packs the car automatically enters config mode, and writes something like UB numero modificaro.

Thanks

Hi there, I am new to this forum. We own a Micro-Vett for several months now and it is driving great. But now the car doesn't charge anymore. I searched, and found a corrowed connection in the charging cable. After replacement, the car beeps when connected to the 230Volt, then a few clicks, then one loud click and then it stops. I watched the charger, and the red charching light is activated about 1 second before it stops.
Any Idea what I can check and where it is located in the car?
Regards,
Ernst

Hi Ernst, Does this only happen while charching or does it also not drive? I had a similar problem where the main relay would turn off after a couple seconds, it didn't drive nor charge. After connecting to the bms via rs232 and sending "t" I noticed a cell temp of 80 Celsius which rapidly increased everytime I read data from the BMS. It appeared to be a faulty ADC on the pcb. Solution was disconnecting ntc connector. btw the main relay is mounted in a box together with a current sensor underneath the front-right headlight.

Below you can see the error: temperatura elevata: veicolo in blocco and in the most right row 92.5 C.
This wasn't the actual temp after measuring the resistance of every ntc and the cells with infrared.

Hi, If the master does not detect every single module the same thing happens. You could check the AMP connectors (can-bus) from the front and rear modules for corrosion.

Good day.
Tell me what could be the problem?
I check the voltage of the cells (RS-232) and I have all the cells 2,9 volts temp 20c, although in reality about 3.5v
battery voltage -285v, rs-232 -202v
charging starts and immediately turns off with a red light
and an error appears "bloque 31"

Hello,
Could you provide a screenshot from rs232 data. My guess is that the bms doesn't read all the cells

hello
yes
I have 2 cars in stock.
one did not go right away, the second stopped giving data 50% bms, then 75%, then 100%

after "t"

120095


after "F"
120096
120097


data on CAN BMS show that bms are sending 0, except for the top 1 with values (40 7A)
120098


what could be the problem in bms ?

Hello, is there anyone who knows how to adjust the ampere meter?
Mines shows about 9 Amps to low. It says -8 on stand still. Now the fuelmeter drops also much slower then before.

Hi, thanks for your reply. I checked the sensor side, that's ok. Where is the other side of the cable connecties? I get lost trying to follow the cable.
