Update

Battery ready 36S28P, road tested, 80 Ah, 500A nominal

Custom BMS ready - idle balancing algo - road tested including public Type2 charging 

CAN bus programming for BMS in progress - spoofing stock BMS for cell voltages and temperatures

2 sport windshields installed

Elcon TC 3.3kW charger purchased

Yes, this looks good because it shows a few things :

> The 12V power supply on the motor controller is working, this also means the fuses for basic functions are ok.

> The motor controller processor is working since it sends the odometer value over the CAN bus

> Basic functions on the ICM (interface controller, small metal bok above the front lamp) and the display are good as well since they receive the mileage value and display it correctly. Overall the CAN bus should work in the scooter.

The charger is not needed for the VX-1 to work, it has only roles when charging and calculating battery charge level.

As the next step you may wish to check if the ignition switch itself is ok. There are two ways to do it (1) by removing the plastic covers around the switch or (2) by removing the perforated metal cover from the motor controller to have access to the two wires.

Right at the red marking, two adjacent pins (pins 1-3 and 2-4 are identical) so for example connect 1 and 2. This should enable the 12V power supply for the ICM and the display. It is safe to do it, I used it myself. You may also need to check the large white Littelfuse fuse at the BATT+ terminal.

You may need to remove the perforated metal cover to have a better view and see that connector.(by disconnecting the battery terminals first then the other cables. Needless to say when the battery voltage is reconnected you need a light bulb to balance the voltages between the pack and the MC (supercapacitors). The 4 pin connector will be at the bottom left of the MC based on your picture. You can also check the 150 (or 200 A) fuse at the + battery terminal.

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.

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
