Hi Thomas,

   That is a strange problem :) When you mention encoder, is that the throttle on the handlebar or the encoder on the rear wheel ?

Right, if you could ask them what is their plan for the upcoming period. I think Vectrix has valuable assets as the complete bikes, spare parts, the firmware source codes and the patent for the regenerative braking - just to name a few. 

Hi, last year I have ordered various items from the webshop, it was still fully functional. Now with the page gone I was wondering what happens to the inventory since there seems to be constant demand for parts from the people using the scooters.

Saving the site resources seems to be a good idea regardless, I will do the same.

Theoretically yes - I will know only when I see it working - a matching BMS firmware version will be needed. A converter cable is also required which was available from the Vectrix webshop but can be reproduced as well.

Overall it is not easy but doable. The net result would be a 3.3kW charger that is two times faster than any of the original Vectrix chargers.

These are fairly standard and could be found in many EV related webshops, I got mine from the Aliexpress. For the Vectrix the HK-J-144-23 version is the proper one (must be capable to provide the required 150 V voltage basically).

I will build in mine in the next few months and can share the details along the way (currently I am still on Runke V2).

That is the old charger, the most you can have is withthe Dugas firmware and software (http://dugasengineering-com.3dcartstores.com/Vectrix-Support_c_16.html) allowing you to set up your charger for Li-Ion. This would give you sufficient functionality - however as with all Li-Ion you must add BMS as well. The challenge is no BMS will be able to communicate to this charger not even the Vectrix ones.Accordingly the BMS should work independently from the charger.

In summary it is pretty complex with this charger. The golden Runke (only V2) is the good candidate or even the Elcon TC family which is the best.

Hi Thomas,

   There are two types of chargers, the older ones with silver housing and the newer golden "Runke" ones. Which type do you have including the product / version number ?

Indeed the voltage measurements (per cell block vs. BMS) are needed to see if it is an issue with the cells or the sensing wires.

The stock BMS works on a simple concept called top balancing, it will attempt to charge all cell blocks to 4.2 volts. In the EQ mode the blocks which reached this voltage are "discharged" with the respective balancing resistors - however due to an equivalent 1A charging current still flowing they actually maintain their voltage level. The rest of the cell blocks are still charged up in order to reach the same nominal 4.2 volts eventually.

The gauge is not really important, it is just FYI for the expert user :) You can set it to any level you want from the diag app.

Yep the shop webpage has disappeared, maybe Vectrix is sunsetting their support - hoping users will support each other with the knowledge and parts we collected over the years.

Almost :) You can skip the step 2 - the values you see in the Diag are based on CAN bus.

3) Check all suspected cells with a multimeter when the Vectrix is off and while it is on

4) Check the respective cell measuring points on the BMS card

The next step can be decided based on the results.

Hi,

   The charger firmware aborts the charging process if any of the measured cell values - in fact any of the four High Cell values - are above 4.2 V. This is for safety reasons.

Your problem in the 4.209 V on that block, that needs to be fixed. Since the block under it shows as 3.941 V it is quite possible the small wires that are used for the measurement have a minor contact problem distorting the values measured by the BMS.

The BMS is simply a 4x9 channel multimeter (ADC) in its default state when the balancing is inactive.
