Thanks, that clarifys a lot of things. That´s all I wanted to know :)

The lacking amounts of free pins was the problem with the heater, that wasn´t clear to me :?

As I stated: TÜV wants to have Heating and Isolation monitoring, so these would be needed^^

I will reach out to you, when the project ...

Okay, then perhaps we should do it the other way around...

So how is your system working/ what do I need to implement it?
Which devices are needed to run the components: Outlander Stuff and BMW Hybrid pack and Chargeport.
Only your EVS VCU or anything additional?

Are you willed to integrate the ...

No, I meant the EVS VCU, which is your product, or am I mixing sth up here?

It doesn´t need to be the Zombie, i just generally asked what vcu is the best for this project!

You stated that Zombie doesn´t take over BMS work, so I looked into EVS VCU.

Another point is ...

@Thomas: They came up with their system when I thought about building all that stuff. But I am not quite happy with the mechanical design they did, not to hate on that, but as an engineer I think some things could have been done a little different....

@tom91 I know that you build that system, but ...

Small project update:

Plans changed a bit, as the engine was more shot than I thought...
Pulled the engine after redoing the wire harnes and disassembled it. Engine is rebuildable, but not worth it in my opinion, as I would need a Oldtimer licensplate here in Germany to run it in bigger cities, but ...

Hello guys,
need some help with strategic decisions and if I got everything right…
I am a mechanical engineer with experience in batteries and OEM components (integration), but software is more the problem.
I have been reading here for a while and decided, that I need to take the next step :D
I got ...
