I have just updated the V2.30 Zombie update on my Peugeot 106 with a Leaf drive unit and Orion BMS.
I can confirm that the reverse is now fully operational.

The Leaf charging fix for Low Current PP detection is still not working.
I use a 16A cable with a charger set to 16A in my garage due to supply limitation.
It works with Tesla's, a Zoe, Evora EV and Elise EV using the Orion for PP/CP control.
I can charge the Peugeot 106 using a 32A cable but the 16A one doesn't charge, only detects the plug in and starts the water pump.
In Spot Values PlugDet is on but PilotLim is 0 on the 16A cable, with a 32A cable PilotLim is 14 as reported by the limit in the EVSE.
There is a CableLim of 0 with either cable and PilotTyp is set to Absent or both cables.

Can it be confirmed that HVRequest now functions as I require it to use Chademo with the Orion.

It works for others. So please post your findings, or link the thread on this.

Did you see that someone had issues and resolved it by verifying they had the right port used. viewtopic.php?t=6674

Please update thread title to include more refence eg. V2.30 Nissan Leaf PDM Charging issue

I am using a Type 2 port so from reading the post you mention above, I may need to add or change a resistor to suit the Leaf input.

Appreciate your time Tom.

After much testing using a resistor decade box connected to the PP connection, I now realise the issue is because I am using a Type 2 socket in place of the Type 1 that is standard with the Leaf.

The Type 1 plug has the switch on it that puts a 150 ohm resistor on PP to confirm fully connected and adds 330 ohms when disconnecting to stop charging via a shorting switch on the plug release lever.
Type 2 relies on a shorter CP pin to do this.

The reason the 32A Type 2 plug allows charging is because it has a 220 ohm resister which is close enough to 150 ohm for charging to commence.
The 20A cable I use in the garage has a 680 ohm resister which is too high to commence charging.

I cannot see a way round this as the Type 1 plug action is I assume hard wired/coded.

Check your wiring unplug it from the pdm measure if there is a resistance PP to ground.

Plug it back in and grab a few CAN Logs of various resistances between PP and ground on the charge port.
Id say:
13 A 1.5 kΩ
20 A 680 Ω
32 A 220 Ω

Then we can see what the PDM reports for values for the Plug detection section on CAN frame 0x390

OK I checked PP to ground has a 2.7k resistor as required on the Type 1 socket although I have a Type 2.

0x390 bit 5 reads 80 for no plug and 1.5k. The car does not go into charge mode

0x390 bit 5 reads 84 with a 680 Ω resistance. Car goes into charge mode on around 750 Ω (starts the cooling pump) but no charge initiated.

0x390 bit 5 reads 88 with a 220 Ω resistance. Car goes into charge mode on around 250 Ω (starts the cooling pump) and charging commences.

I guess all the above is correct for a Type 1 scenario where 470 Ω is presented as the plug goes in and 150 Ω as the latch is closed.

As the plug is removed the resistance will transition from 150 Ω to 470 Ω to disable charging before the pins are disconnected.

I believe type 1 cables are always tethered so cable size is not sensed by the charger and current is controlled by the EVSE on CP comms.

Type 1 cables have fixed resistors that are the same for all sizes of cables.

You would only be able to use a 32A cable with the leaf pdm. You can however use a transistor or something to connect a 220 ohm resistor to PP once you insert any resistance between PP and ground. (type 2 cable)

Can you rename this topic to something like, "Charging with Leaf PDM and Type 2 socket"
