official approval regarding original trans-axle / German TÜV

[vita]

Hello,

I am new here, but I’m interested in ICE to EV conversions for a while, I’ve been watching Damian’s YouTube channel for 2 years by now. Recently I started gathering information and roughly planning a conversion. This forum and Wiki are very helpful in this regard, thanks for that! The most difficult part seems to be the official approval. I'm living in Germany, so I’ll need to pass the TÜV. I suppose here are some Germans who have already made the TÜV experience .

Since conversions (in Germany) focus on motor swaps (“Motorumbau”), the gearbox and the remaining drive train is untouched. Is this because of TÜV requirements? (I haven’t purchased the “Merkblatt VdTÜV 764 “ paper yet.) Or is it because of practical reasons? Is it possible to make a Tesla swap (or GS450h / Prius trans-axle swap) street legal here in Germany as easy as the motor swap only? So it’s mandatory to keep the original gearbox or not?

kind regards,
Vita

Yep, already seen. Unfortunately it's not answering my question.

In the info sheet there is nothing about whether only the engine or engine and transmission are converted. Information sheet 751 must be observed for safety-related changes. In my view, there is nothing to be said against the complete motor gear unit.

In the meanwhile I’ve purchased the TÜV info sheet and read it. There is indeed nothing explicit about that matter. But there is a safety requirement regarding unintended moving off. Two separate activations are required, on a motor only swapped manual transmission this is given (pedal and shift stick). But how to implement that requirement in case the original gearbox is replaced by a Tesla drive unit?

It's just like an automatic transmission. A switch for (P) R N D and an accelerator pedal (Gas). If this is not safe enough, you can set that R and D are only activated when the brake pedal is depressed. After switching on the ignition, a start button must also be pressed to close the main contactors.

Sounds logical, but what bothers me a bit, there is a thesis about EV conversion, which claims there must be a mechanical interruption between motor and gearbox (e.g. neutral on manual gearbox). I also haven't seen Tesla conversions in Germany at all, which is popular everywhere else. Maybe someone else has seen sometihing like that in Germany?

You can call TÜV Nord (https://www.tuev-nord.de/de/unternehmen ... fahrzeuge/) and ask for Klaus Baumeister. He will be able to give to a definitive answer. Conveniently he works in Hannover.
I've never heard of the mechanical interruption requirement nor can I interpret 764 that way.
