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 ...

Other 3D printed items:

Since I basically closed off the full engine bay, the previous side scoops dumped directly to no-where.
Easy fix was to 3D print some adapters, and duct the airflow to the rear brakes.
Print was broken into several parts, glued using acetone.
Material is CF-ABS, printed with ...

Coolant Pumps & Pipework

This is still a work in progress, but I’ll show how I mounted the 2 Bosch pumps.
Each pump is variable speed, 100hz PWM.

4 aluminum tubes run the center tunnel, 1 pair supply the motor cooling, with another pair being used for the battery cooling.
All other heat devices ...

Battery Tray

I suspect this to be the most controversial part of the fabrication series :lol:

Given my poor battery choice, packaging was always going to be an issue.
Early on, it was decided to split the build into getting it moving with 1 pack, then migrating to the 2nd pack afterwards at a ...

Motor Mounts continued…

So I realized that I have two previous posts for the motor mounts, you can check those out for the rear subframe adapter, as well as how the Chassis C-Channels were made.

In this post, I’ll try to put it all together, with the front mount that hangs between the C-Channels ...

Just an update.
CAN3 was a fail...
At least with my CAN messaging strategy of just dumping whatever message needed into it's respective timer, which resulted in a cue of 4-8 messages to have to send.
May have been more successful if I spaced them out by 5-10ms each, as the duration between messages ...

Just checked my notes and confirmed, the resistances should all be tied to sensor ground.
All the resistances are variable, so a high (+12V) or low (Grounded) state will likely trigger a fault.

Hopefully no damage is done to the sense circuits for the lock signals, etc... I'd assume they're all 12V ...
