These seem to follow vda590 standard - same as other MEB modules.
My guess by the prismatics is that they are Catl (most likely) or SK made.
Given that they are 1P it would be interesting to figure out what the current capability is, very likely not far off from 12s2p catl meb modules divided by ...

Yea, I don't want access to anything resembling the prod environment. At this point I don't want anything at all, before I validate that a bunch of data can be searched nicely on my own box, locally. Too many projects to tell when that will be.

Another problem imo is that OI robots.txt + botwall seems to have killed any google-ability of anything OI, at least with good quality.

Re: AI-assisted search for the forum/wiki (RAG “librarian”)
I just ran a quick greasemonkey textual scrape of Wiki (300ish pages) through mediawiki api (at sane human speeds) and used various tiny models, only with vector embedding database, so no actual hybrid search by query keywords. Results are pretty underwhelming, to say the least..

Jacobsmess totally agree on the current search limitations, especially the 3+ character minimum. I often find myself trying to come up with what I could add to search short sutff(IQ, OC, UV, etc.) and part numbers where exact matching matters.

I’ve spent most of my life in forums of various sorts, and one thing I’ve noticed is how much time it takes to “stay in the loop”… or to find that one thing you vaguely remember reading 5–10 years ago. We finally live in a time where improving this is actually practical.

Re: Dynamic PWM modulation in STM32-SINE FOC to increase the inverter lifetime
So the latest commits on github now do per edge loss estimations, which should be much more closer to reality.
There are now a few more power stage presets, namely LDU, SDU, Leaf gen2,bmw I3ish one along with the vectrix vx-1 powerstage. I tried to add as much as I could about each of these ...

Re: Vectrix VX1 MotorController OpenSource/DIY
so my observations from stock inverter operation seem to be correct- the stock inverter firmware runs sine LUT + phase advance LUT and something akin to DPWMish scheme at all times, where it makes sure only two legs are switching at any time, meaning, that implementing STM32-SINE -FOC build as is ...

Re: Dynamic PWM modulation in STM32-SINE FOC to increase the inverter lifetime
My Initial idea to somehow qualitatively assess what modulation frequency and at what point would be suited is to extend the IPM Motor Sim to work at a lower layer to try and add pwm modulation data and some switching loss model in to it. Then some sweeps with each DPWM style could help understand ...

The only data point I have for zombified inverter longevity is this comment:
Basically the situation is the same as before, we just acknowledge the fact that SDU inverters broke at an over-proportional number with the OI board. I can't really put a percentage on it but over the years I sold 350 ...

Dynamic PWM modulation in STM32-SINE FOC to increase the inverter lifetime
This is a separate thread from this post . I went digging through old OEM inverter/DSP asm code and fell into the PWM rabbit hole. I checked most of open source foc codebases if anyone implements any optimizations like that and to my surprise I found none, maybe for a reason. My current goal is ...

Re: Vectrix VX1 MotorController OpenSource/DIY
I would like to slowly proceed with creating a zombie for the bike MC, the old DSP is doing a pretty rough commutation, with phase advance at higher RPMs.
Hopefully this brings:
Longer life for IGBT power brick due to much more effective switching.
Free choice in sixpack switching frequency ...
