Hello Azzuro,

Thank you very much for your encouragement, it’s really nice to be able to enjoy the scooter after 2 years back in service. His general condition was worth it because he has only 6000km.

Does Vectrix have a start method for displaying Umin and Umax on the dashboard when driving? This is the case during charging or in the event of a defect.

Have a great day!

Hello Azzuro,

Thank you for this new information!

I don’t remember changing any voltage or current values in the configuration. Maybe it’s the previous owner!

Regarding the cell voltages min and max, I do not see any data that resembles voltages at the address (FEF3). However, it looks like we can find this information on the frames (FEDA40 to FEDA43). I need to record this data while driving in order to deduce something from it...

Have a good evening and see you soon!

Hello Azzuro,

These informations are valuable! I managed to interpret the data in this file to create a dbc file. After connecting on the scooter and using PCanExplorer, I managed to read the frames that are listed in the xml file.

Tomorrow I will make a screenshot for you. If you notice any errors in interpretation, I would be delighted to read your comments.

Thank you very much for your help.

Best regards,

Lionel

Hello everyone,

I would like to monitor the voltages of my battery pack with a recorder (without the Vectrix diagnostic app) while I am driving. I would like to identify the least capacitive cells. Did you have access to the CAN DBC ?

Thanks you,

Lionel

Thanks you Azzuro. I'll check !

Hello Azzuro,

I checked the signals listed above.

All 15V voltages are good.

But after checking the UN, UP, VN, VP signals... I noticed that Un does not vary.

I checked the VT71 signal at the input of the U27 optocoupler. And no signal either. I checked the PWM_UB signal and the signal is indeed coming from the TMS320 processor.

I checked the optocoupler’s input diode; it has a slightly different threshold voltage than on U29 and U31.

I will order the HCPL-0453 and replace U27.

Have a good rest of your day,

Lionel

Salut Azzuro,
 Very good idea, I’m going to start looking for used MCs.

  Are there any versions to avoid?

Have a nice day,

Lionel

Good evening Azzuro,

Thank you for these measurement records, which I keep as a reference. I also think that the malfunction of one or more stages of the IGBT is the cause of my problem.

I once connected the battery pack without pre-charging. I had to replace one of the supercapacitor fuses. I probably damaged the IGBT at the same time.

To check the operation of the IGBT, I will carry out new measurements:

- control the supply voltages +15V1 to V4

- check UN=f(UP) VN=f(VP) WN=f(WP) to be sure that the command is correct

- check A=f(UP) B=f(VP) C=f(WP)

I hope that these measurements will help me identify if any of the 6 stages of the IGBT are malfunctioning.

To make these measurements, I am lucky enough to be able to use a 2-channel isolator.

I hope to find the time to do these measurements in the coming days.

Thanks again.

Have a good evening,

Lionel

Thank you Azzuro, and sorry for the inappropriate suggestions. Also, there is no urgency.

  Have a good evening,

Lionel
