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.

that suggests a charger problem, let me contact you via email.

Hi, does it turn on and ride yet ?

Since it is the ignition switch it is protected from tampering for obvious reasons. To test it you would need access to the Motor Controller. In case you have access to it I could describe which two pins should be connected on one of the connectors which is equivalent of turning the ignition switch on.

For the "Quelli del Vectrix" WhatsApp group please drop me an email (me@mecano.hu) and I will reply with the contacts. I prefer not to share their numbers here.

Replacing the ignition switch is not easy (it is even protected by special screws those need to be drilled) so only recommended if you are certain it is faulty. Do you know the Italian Vectrix community on WhatsApp ?

They are small black Philips screws between the ribs of the black decals.

Hi,

  Have you managed to get the missing details, or do you need them yet ?
