That is pretty fu**** up.
I wonder if it can be solved in Poland as they seem pretty benevolent with many weird stuff.
//edit: Or some local University might be helpful at least with those EMC related stuff as they tend to provide measurement services.

TÜV Süd told me EMC 10kEUR, regen testing 8kEUR, and then stopped as we both agreed that these numbers are out of discussion. 3,5kEUR would be a bargain ;-)

That seems like they just do not want to do so. And instead of saying no they just give you a ludicrous price.

I find this

Hello,
what is the cost of passing all tests required by TUV in Germany?
I live in Czechia and when I asked TUV Czech what it would cost to get a roadworthy vehicle they quoted at least 3500€ to test EMC, electric safety, brakes, and steering. And if they find something more to test, it will get ...

Yes, mainly it is for the possibility to use both motors and switch to ICE when wanted.
And also I am a little concerned with the high speed of MG1 as it has a bigger diameter than MG2. I know many people let it spin fast, but how long will it last?
I still wonder what is its torque rating as in ...

They use this

But this MG1 has only 40Nm, so it is tiny
Does anybody know the rating of GS450h? I see everywhere just wild guesses.
But even if it would be about 100Nm, then it is about 3 times more at the engine shaft and 300Nm sprag ...

Hi,
As the stock MG1 limit is just about 7000 RPM, I wonder if somebody considered fitting a one-way clutch to the input shaft.
I was looking it up, and Toyota already uses this at PHEVs to extract power from MG1 at low speeds and prevent the engine from rotating backward.
So it looks like a ...

I did some calculations to see how power splitting would behave with my engine and final drive
Table showing maximum power MG1 and Engine can deliver to wheels and percentage of that power relative to total engine power.
At higher speeds and low engine RPM are those percentages over 100% because ...

There's the work being done to try to use the BMW i3 range extender (rex) to charge a battery. That should eliminate a lot of the integration efforts to be able to use ice to increase range.
See https://openinverter.org/forum/viewtopic.php?t=3749
Or if you do a true hybrid and pull it off that ...

I see, I have tuned a few control processes and it can be quite a pain to get it working as desired especially when there will be regulation delays and inertia. Even car manufacturers sometimes have issues to fine-tune throttle response.
Plus PHEVs are somewhat ugly ducklings hated by both sides ...

If there is a possibility to run MG1 at a constant speed and monitor the current size and direction, then it shall be relatively simple math.
With the engine running just set MG1 to match it (in the opposite direction) and then just apply throttle to the engine.
Lexus states they run it in 8-speed ...

Hi folks,
I wonder how feasible it is to convert old ICE with Lexus L110 transmission to PHEV. It would be nice to have about a 50 to 100 km EV range and keep the engine for nice sound, longer trips, or extra power.
I'm aware there will be some additional work, like power steering conversion ...
