Some positive news!
With a 'New' charger, using my existing codebase, I've been able to achieve ~40A from the EVSE.
The new wattage limit is 8900w (40A @ ~240vAC)

Component protection is showing normal (not triggered... Yet anyway...)

Details of the new charger are:
HW: H35
SW: 0088
ODX: 4007
Part ...

I've ordered another charger.
Figured I'd either prove two units are non-functional, or migrate over and test some theories in getting a charger to work as a slave unit.
This will require Focci or a CP-PP master; but would allow you to gang chargers together for 11, 22, 33 kw... etc.
Will also ...

I'll try to sort out some of the BAP messages, it may be of some use to you. the Accumulated power may be difficult, but there is likely more to decipher.

I've sorted most of the messages out... But haven't had the chance to document as well as I'd like.
Ironically as soon as I did, I found several ...

With the port disconnected from the charger unit, I have the following:
PP-PE Resistance @ 2.7kohm
Open Circuit on CP-PE
(I'll measure it with the charger unit connected in a few hours)

I haven't been able to find anything about the tests, however I have several that are failed. I believe #38.
I've ...

I've been digging deep into this over the last week.
I've upgraded from 0070->0079->0089->0093
No major changes between the various revisions, other than some new faults.
Dala had a log from a Taycan which helped to confirm/eliminate some items.
I've added the logs, converted to Savvycan format ...

I'm using a fork of your fork. :) Not much has changed though.
I'm using a 2518FD SPI CAN channel added into zombie. So my Can-Send is slightly different but other than that it's pretty much the same.

I'm starting to think that Component Protection is tripped and causing a charge reduction.
I ...

Great video!
Would you happen to have a CanLog of a charge session?
I've begun updating some of the documentation and wiring diagrams, As I've finally got to the stage of installing and actually charging with it using Zombie. Been trying to align whatever values/datatypes between each. Since I've ...

That is amazing!
Great work.

If you're looking to control the fuel gauge, if it's anything like the newer stuff, I've been using a 1Kohm AD8403, with two of the resistors in parallel, to make a 500ohm variable resistor.

The newer clusters seem to monitor the line resistance, sorta' akin to a 3 or ...

Yeah Its working on my bench setup,
I'll take another look over the weekend, just need to finish another project with my bench powersupply.
I'll grab a CAN log of the charge session initialization as well.

The teensy codebase is messy, as the first one I uploaded contained just = in the if ...

If the simulate question was for me, it's not required
It was included just to mock having 400v applied, as I was bench testing with just a dummy load.

As for the parameters, Haven't looked at your codebase, but many of the ones I have mapped aren't needed.
I do suggest migrating to the ESP32 CAN ...

While searching for DBC files, I stumbled across this university team using the iBSG from Valeo.
Their DBC seems to indicate that it's a JLR based unit - Likely from the X8578 - F-Pace Mild Hybrid.

They were sponsored by Valeo, so it makes sense the DBC came thru that route.

You may find the Teensy to be a more fitting processor for a bridge/router, Hard to ignore the horsepower of that chip. Plus there are a ton of Can Libraries to leverage.

For a more official device, the https://www.mrs-electronics.com/products/detail/can-gateway-module seems interesting as well.

I ...

A lot of the values being sent to the charger are similar enough that with the limited data, I end up copying the value into the various CAN messages.
The thing is that some use different scaling. I think that's where most of the copying values originates from.
There may be some back and forth ...

Check your output voltage is above 300v
Sounds like how my unit was acting when I didn’t have a high enough resistance load and a low wattage EVSC wall plug.
After a duration the unit shuts down on low output voltage.
I think the limit is somewhere around 250v
I needed to place two elements in ...

Oh no, the magic bytes for the post I made a few days ago should be MQB.
I’ll reconfirm though.

Use the magic bytes from Damien,
The bytes change depending on the generation of chassis,
The Bytes and signaling for the 11kw chargers are for the MLBevo generation, while the 3.6 and 7.2kw chargers are likely based on the MQB generation.

But there may be some crossover or charger firmware ...

That makes sense, I guess they don't care too much on Motor RPM after the start signal, as any loss in motor RPM would immediately kill the power assist, which likely isn't ideal.

0x100 is ESP_01 - Sent at 20ms intervals - Has CRC - Magic Byte 0x01, this has Stability Control Status signals.
0x103 ...

In your sketch, some of the ids are in decimal, but notated as hex.
for instance your BEM_05 has a ID of 0x869, but it should be either 869 (decimal) or 0x365 (hex)

Is your charger coded for a EV or Hybrid? If it's coded as a hybrid, may be worthwhile trying to code it as an EV (or vice versa ...

Chassis Can log, just 'idling'
RPM is at 655
Rack seems to be power assisting

Had some example code on the forum already:
dMO_Speed_01 = motor RPM (Value is RPM*4) - if you send a value of 4000 it should spoof a 1000 rpm idle.
may also be worthwhile setting bMO_Motor_runs to 1


//-------------Motor_03---------------//
uint8_t iMotor_03_Checksum = 0;
uint8_t iMotor_03 ...

I should be able to get some logs for you today. Weather is cooperating for a run around the block.
I can also send along some code to generate motor_03 if needed.

I will review the code when I get a chance and approve it.



So you have it running on an ZombieVerter with other components connected?


Bench tested with the most recent vehicle_testing branch.
I did upload it with the Simulate function still active :oops: , so may be best to reject it and I ...

Hey,

Sorry about the delay. Had to learn GIT enough to not make a total fool of myself:
https://github.com/Mitchy6/Stm32-vcu_Template/tree/Vehicle_Testing
** Remove/disable the simulate function in 'vw_mlb_charger.cpp' before using **


Ran into some issues when testing, but it does initiate a ...

Post up your sketch to see if anything is sticking out as a potential issue.

I wish I could help more with these, but I don’t have a unit to test with.

It is a good sign that it did begin to charge though!

I should be able to send along a log from a 981 during my next outing, But it may be a few weeks until I can get a log while moving.
I can forward one while stopped/parked pretty quickly though.

Do you have any micro controller to allow sending custom CAN messages?
May be easier if I guide you thru ...
