Hi Tommaso,

  Do you have access to the motor controller ? If yes, you may need to verify the battery voltage (on the screw contact terminals). In case you have 120+ volts then you could try to turn on the 12 volt power supply by shorting 2 adjacent pins on the PS enablement 4 pin connector on the top.

Update : Added 2nd VX1

Glad to hear :) Based on the above details it can definitely work. In case you are not confident a local car electrician should be able to interpret this as well.

Hi,

  I would say it is relatively straightforward. The question is where to get the black box from :)

Azzuro

Yes, it can certainly work. David Dugas may need to give you the necessary instructions. Important to verify if it is designed for the non-CAN or the CAN enabled PFC charger version. Based on your picture you have the CAN enabled version.

/ Azzuro

Sure, without the outlined modifications I am afraid you only have the EVPS charger as a feasible option - and accept the 1.5 kW limit. Firmwares are available for the various battery options.

Cheers, Azzuro

Hi,

It takes much more than just connecting the wires. The stock chargers perform additional functions (for example calculating the SOC, remaining distance, etc.). Compared to this the Elcon TC/PFC chargers are fairly simple. In summary the CAN communication is significantly different starting with the addresses. You will need custom components from Poland / Dugas Engineering / Fuel Free Motors to make it work including the BMS integration.

Building a converter yourself (I've chosen this option, in progress) would require in depth understanding of the various firmware and CAN messages.

Hey Carlos,

 Yes based on the CAN address difference I would assume there are minor differences between the two images (unless the firmware detects the rear/front variant and changes the address accordingly for the MCP2515). I will check in a few weeks. On the CAN communication level the two boards are clearly differentiated.

Hi Carlos, out of curiosity are you sure it is exactly the same firmware for the front and rear Battery Monitors ? The reason for my question is they have different CAN addresses 4D and 4E.

Hi Andrei, I guess you would need to buy replacement boards from vectrixparts for the boards those are burned. In addition you can ship the damaged ones to us an we would try to fix them as part as our learning curve, no guarantees though due to the extensive damage. If successful you would have spare boards as well at the end.

Good to know Carlos so single code for all boards. Hopefully other owners with some skills can use this method as well. / Azzuro
