Re: Simp BMS

I think maybe this thread had it mentioned? Maybe I read about it being reason for the cell12? when I was browsing for solution to my problem before posting it. But I can't remember where it was used or anything. BTW, opened up the 10S and 8S CAN Modules covers to measure voltages from board to rule...

Re: Simp BMS

My bad, I forget the fact that the E-Golf has 10S modules, let me tweak my code and upload for you to test. The filtering is to keep starting modules and messages for empty voltage from messing with things. New one here: https://github.com/Tom-evnut/VW-bms/tree/master/VWBMSV2 THANKS TOM ! now it wo...

Re: Simp BMS

Please create a can log of connecting Module #8, so the 4s + 4s. this is required due to the way it powers itself. Once this shows correct data, connect the final section. I get the feeling something is weird about the wiring setup causing errors in the module voltage reading. Have you connected th...

Re: Simp BMS

So there is some more checks for plausible values being sent by modules, you log is showing 0x1CC, 0x1CD, 0x1CE as are expected for module 8 but all with 0xFF or 0xFE for cell voltages or translates to not correct cell voltages. The modules messages are discarded if they are shown as 0xFF in any of...

Yesterday I plugged in CAN modules 5/6/7 and 8 (With the cell interconnect wiring for their respective cell Groups.) The module #8 is not Sensing/sending vo...

Re: Freelander EV With Gen1 Leaf electrics and EVBMW VCU

As Celeron55 has stated:

'Use proper CAN wiring and termination - the inverter makes a considerable amount of electrical noise."

So the vcu might indeed be to close to source of that noise.
You have twisted pair cables on CAN wires in this car too?

Re: Is a Leaf BMS OK with the Battery being split in the wrong place?? [SOLVED]

OK stupid suggestion time. What if the connections going to the BMS either side of the proposed break at cell 56 were passed through a relay so that with the ignition off the pack is broken to the BMS but when the ignition is turned on they are connected again. Provided they were timed such that th...

Re: Is a Leaf BMS OK with the Battery being split in the wrong place?? [SOLVED]

When you are driving/charging the pack is complete and BMS works. No problem there. When car is parked and batteries split, there should be no consumption and no real need for the BMS to stay alive? I plan to cut off all power when my car is parked. Including the BMS. What would it do anyways when b...

Re: Leaf Gen 1 Inverter Board

Has anyone made forward/reverse switch for the leaf vcu?

Edit: ok I just made a code that changes torque request to negative when IN2 is high. Seems to work just fine (full speed reverse though like this, so maybe I will make a software limiter)

Re: VW Golf GTE battery

I have an opened battery pack that still has the modules in it etc. I only cut out the contactor 12V and GND cables from the loom.
Looks like this:

I also have unopened pack. And a connector for the external CAN bus

What would you want checked?
