No charge current with Leaf PDM and Zombiverter VCU

[tom91]

Does the Zombie go into charge mode? This is still possible with key off, what firmware version are you on?

0x?8 drives plug detect nothing else gets changed.

Only when actually capable of charging does it show some other values.

[Rustybkts]

Firmware 2.20A
0x088 each time plug is inserted on 7kW EVSE.
PlugDet On
PilotTyp none
CableLim 0
PilotLim 0
Opmode 0
ChgTyp 0

[tom91]

Does it go into charge mode?

[Rustybkts]

Does it go into charge mode?

No only PlugDet On

[tom91]

What are all your settings? as it should go to charge mode if the parameters and settings allow.

Once the PlugDet is set and the Zombie is okay to go charge it will. try.

Ofcourse you will need the whole system working as it will want to do precharge and such.

[Rustybkts]

All settings are as the attachment sent earlier.
I'm pretty sure they are all correct.

[Rustybkts]

All HV control has been working for weeks as the inverter and DC-DC ore fully operational

[tom91]

Is Chgctrl enabled, set to 1?

[Rustybkts]

Is Chgctrl enabled, set to 1?

Confused I am.... ChgCtrl set to Enable but parameter log shows a 0 set.

[Rustybkts]

If I set Chgctrl to Disable I get a 1 on parameter log.

Still no charge so will take a long look at the parameter log.

[Rustybkts]

I now am displaying PilotLim as 28A but still nothing on opmode.
No LastError, Chgtyp or HV contactor operation

[tom91]

PilotLim as 28A

Sure is the PDM trying to activate the EVSE?

What opmode is it in? It should be in off when trying to go to Charge

Please log: Opmode, Plugdetect, Pilotlim
Also a CAN log please.

[Rustybkts]

Opmode is off
EVSE App displays "ready to charge" and a limit of 32A when plugged in.
Battery management parameters all correct.

[tom91]

Okay then I cannot help you. Your setup is not behaving as everyone else running the 2.20A release. Also please include more info in stead of the bare minimum this gives me nothing to go on.

[Rustybkts]

Ok thanks for your time. Looks as if the ChgCtrl is working backwards somehow.

[tom91]

#define CHGCTRL "0=Enable, 1=Disable, 2=Timer"

Zero is fine so that was not it.

So I have zero things left for you. You download the release right,https://github.com/damienmaguire/Stm32- ... /tag/2.20a, and used that for the update? You did not compile your own code?

Please show me all your spot values with the charge plugged in.

[tom91]

One last thing to try, set "interface" to chademo

Damien's truck params do not show this.

[Rustybkts]

Tom, I owe you a large drink.

Set ChgCtrl to Enable = 0 and its charging.

Might have been a BMS_VmaxLimit or minLimt as I have adjusted a few since setting ChgCtrl to 1.

Charging at 0.7kW and note that BMS_ChargeLim is only 2A. I guess that comes from the BMS so will check that.

Thanks again.

When its all sorted, will add to Wiki a list of parameters used with Leaf drive units as so many are not used, especially on the Spot Values list.

[tom91]

Key here has been 0x?8 on plug in.

Rest of the params been changed along the way and should not have been. Same goes for your wiring, please clean this up to as per wiki documentation.

[Rustybkts]

I did try selecting Interface Chademo and all it did was lock the Zombie to continuous Charging and HV contactors on all the while.

Selecting Interface to Unused dropped the HV contactors off.

Could do with a future update to allow 0x8? to be range from 0x84 to 0x88 as a 16A cable or Granny will not enable the PDM.

Wiring is exactly as wiki docs.

[tom91]

0x84 to 0x88

Not sure this is real. Will need other to also conclude this. As its the first time I have seen this.
