Zombieverter VCU <=> Tesla gen2 OBC

[allard]

Hi forum,

How should Zombieverter VCU interact with the tesla gen2 OBC? Both are connected over CAN2.

I expect the OBC to detect pp in the charge port and then send a "charge request" over CAN to VCU. VCU should then close contactors and signal OBC that it can start charging.

Is this assumption correct?

If so, what settings in VCU and OBC are relevant?

Sidenote: OBC works when not connected to CAN and HV contactors are closed.

Thanks,

Allard

Zombie when you configure the Tesla charger option is looking at id 0x108 to come from the Tesla charger to determine if it needs to provide HV.

What other items are connected to your Zombieverter?

Depending on your board version you can have alot of CAN traffic coming out of the Tesla Charger https://openinverter.org/wiki/Tesla_Mod ... N2_Charger

I also believe at this moment there is a divergence between the Tesla Charger source code and the Zombieverter in terms of CAN implementation so it may not work out of the box. I can confirm after checking both code bases this is the case.

I am updating the code in Vehicle Testing branch to align with the latest CAN format used by the STM32_Charger firmware for the Tesla Charger boards.

Hi Tom,

This aligns with our findings while we investigated the source code. But it is good to know for sure now. I have the board version with the single CAN chip, so indeed a lot of traffic.

Have you had a try at running the Zombie with my modified code and the Tesla Gen2 charger?

We tried but for various reasons without success so far.

We will give it another try this weekend. Keep you posted.
