I have 9 units left.

I think I have a bunch of them. Will check tomorrow.

I have an EVBMW GS450h VCU fully soldered with the automotive case. Contactors, BMW 1-series water pump, Tesla Model S battery heater, E46 throttle pedal and possibly other stuff that could be useful. Located in Estonia but for the smaller stuff postage should not be huge.

A bit harder to ship but ...

I've come across a very cheap one of these and I was wondering how easy it might be to modify the body to remove the diff. Has anyone opened one of these up? Looking at the pics it's difficult to tell but I'd be interested to know if it's possible to separate the motor from the diff and make it ...

More shunts popping up in the US:

Hah, it seems that if you use ebay.com links the prices are better https://www.ebay.com/itm/155875440129 and https://www.ebay.com/itm ...

If you plan for a group buy then from quantity of 12 you can get same or better pricing directly from isabellenhütte.

Marty has been trying very hard to ship one across the channel but that seems very hard. So preferably it should reside in mainland Europe.


You can contact these guys, they run a van like once a month between UK and Estonia. On the way they make stops in DE as well. They have transported a few ...

It looks like they only send evaluation devices out for now.

I have a project that I'd like to use this for but it seems that the availability of the motors has dried up. Anyone else experienced that?

I have a friend that has a car that I believe has this on. I will try to get it for a weekend and capture more can logs.

The DBC has been shared numerous times on internet and I'd guess on this forum too.

This here should be correct https://github.com/gabryelreyes/IVT-S/blob/main/Documentation/IVT_S/IVT-S_CAN_DBC.dbc the parent project has code to make comms easier too.

If this does not work I can dig up the version ...

I have access to a 2021 NX300h (before the model update). I can try and get a can capture if needed.

There have been a couple of threads trying to get the earlier version of this Q211 to work and looks like they all have pretty much failed.

I think here https://openinverter.org/forum/viewtopic.php?t=1683 and here https://openinverter.org/forum/viewtopic.php?p=27545

Also I believe the later ...

so one thing we notice is that when we crank this unit to the max on the amp dials (coarse and fine) it actually goes a bit above 5 amps

So the efficiency of your PSU is a little over 50%? 110v 5A in ~60V 5A out.

I decided to unwrap the wiring harness last night and it's a good job that I did, two lessons:
- it's impossible to tell which connector goes to which string looking at it visually. There is not much sense to it, connectors that are right next to each other are often from a string far away. You ...

Amount x 4S/2S module sets starting from
the slave BMS 4S module.
3x444
2x442
1x422
1x4422
1x42222


This is great information, thank you!

Are the BMS boards different? What I'm asking is whether I could have all the BMS modules be 444? so 12S8P? I do have another pack that I could scour the ...

Will not work, if you change the cells connected to the Slaves it will not work. So for an E-Golf as long as you keep the modules "complete" you can wire them up in any way you want as they are isolated.

However there are quite some unique quirks to the packs so watch out.


I'm a bit confused ...

Ignore me, going to read the manual then wire up and report my results.

So what I mean is this:

SimpBMS 16S.png

I would arrange the modules into 16S blocks (my charger goes to 64V and I can have 4.0V per module with 16S so that is fine me thinks). But happy to do 14S or 12S which would allow me ...

This may be a stupid question but I'm wondering whether there is a chance I could still use SimpBMS if I would reconfigure the pack to be 16S 48V say 5P? I have 2 (almost) complete packs and a SimpBMS and a need for the capacity as ESS, but my house system is 48V. It's a pita to find a good ...

Congratulations! Well done! Is it also road legal and registered as electric?

I would also be mindful that some meters count exported energy as energy used and it will be added to your bill instead of just lost.

We have had these problems here in Estonia.

I know this is a long shot but I have a whole GS450h car in the garage that has gathered a lot of dust and needs to go.

The car is in Tallinn, Estonia and is temporarily deleted from the registry here.

When I bought it, the ICE was a bit broken (something to do with one of the camshafts being bent ...

I will check, I should have a few lying around. Probably of CAN1 variety.

Yes plenty left. I will talk to you privately.
