Sorry I couldn't get involved more up to now, I am in hospital for the next 6weeks.

Best, Toby

No worries the user who was looking found this:

Thinking about an algo in FOC firmware for mppt recouperatiion for 110 or 230v grid tied micro inverters (with extra caps and rectifier) to connect a wind or water turbine ergometer to the grid or an off grid car inverter. Do I have to make a pull request? Up to know I only pulled and cloned from git.

Do you think that would be possible with the vesc6? I plan to use a 180kv T Motor with 12s.

Greetings from Germany,

Tobi

Sorry ya lost me at "mppt recouperatiion" hah :) I generally get the gist that you want to use the VESC to pull charge from a generator rather than drive a motor and given it already does regenerative braking I could see that but you'd probably need to get a hold of someone deeper in the project to tell you if this is a bad idea.

Personally only have sensorless 149kv motor (turnigy sk3 6374) with a 10S battery has been working well for over a year on a VESC 4.12. VESC6 has basically 2 years or so of software improvements and directFETs and guess rearranging things made it so the DRV chip isn't as likely to burn up until it gets to much higher erpm.

Regarding the 180kv motor at 12S that should be within the limits of the erpm that the drv chip seems to end up having problems at and I've heard with the VESC6 that the limit is much higher so I'd imagine you'd be in good shape but would try to talk to the manufacturer directly to see if they can verify.

Regarding github you can fork the project then clone your fork and move your changes there then push them to your fork and can pull request from your fork to the main repo... there might be a more direct way but that's how I've done it in the past for projects.

Dear Shaun,

Thanks for your git explanation in a nutshell, I don't want to break anything so maybe I need to talk with the guy owning the PAID self parameterization stuff. From the hardware side it should work. MPPT means max point of power tracking since PV panels are nonlinear as are wind and water turbines. So we could either use a simple Newton algo or go for PAID black magic... Depending on what the Vesc6 can handle ;)

I also have the idea to enable hard unexpeced breaking for kite mountain boards (ATB in general) by shortly accelerating depending on speed and height of the rider and then break hard to avoid the rider to fall.

All the best from Frankfurt,

Tobias

BTW: I'm an electrical power engineer and you have my biggest respect for this project. Really well done to all of you! Thanks a lot! I just need to transfer some money to finish my trampa purchase.
