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

I am glad you guys on the right track with this fix :) Especially with a blank PIC programmed up, nice one.

Hi guys, in case the temp sensor boards (there is no BMS with the NiMH batteries) are shorted you may indeed have the 7805 5V power regulator IC damaged in the charger. In case you don't see 5 volts on the output it needs to be replaced obviously (can be checked on the 24 port interface as well). This floating 5V powers the temp boards. The new boards should come preprogrammed. I am not aware of a firmware for these neither a programming method via CAN bus with Scooter Diag.

There is ICSP on these boards for low level programming marked as J1. Should the above fail and you need the hex files I could try to extract them from my boards.
