Re: 160 KW 72v Cntroller QS/Yuma 15KW 300A BMS

It seems like the controller in question can be found here:
https://www.aliexpress.com/item/3256802 ... 4itemAdapt

and here is the manufacture's live site:

Sinewave, not FOC, based on the description.

Re: PV NextGen FOC 134v 30kw - $899 - Testers wanted

Have been testing the controller on the bike for over a year now and pulling solid 10kw on a qs205 with a 26s battery without breaking any sweat. The torque is butter smooth and linear from 0 to full throttle and variable regen is as good. Now, I'd be looking to test the design up to its limits, ide...

Re: PV NextGen FOC 130v 200/600A 25kw - $599, Watch Display

Yes, will do that after testing with at least some hardware other than NextGen. Technically, there is no reason why it would not work but since it taps into PWM control, there is a risk of blowing something up and I don't want people get mad at me when that happens. There are also corner cases like ...

Yes, boost charging is specific to NextGen controllers. In a nutshell, boost charging is implemented and it works well. All easily configurable via iOS, Android apps or a mini touch display. I'm so thankful for your answers Vadym, to clarify, the feature is implemented on the NextGen but not yet on ...

Re: Nucular electronics - complete kit for ev! [beta]

I would agree that this question is best asked in VESC related threads. Hint, hint. And for the record, charging via motor requires proper implementation of this function in the software. Unless you want to blow up your hardware. You connect your psu like in the schematics Sam posted. And you set up...

Re: PV NextGen FOC 130v 200/600A 25kw - $599, Watch Display

One big reason I wanted to keep wires outside of the heatsink enclosure is the signal integrity. Having a bundle of wires going close to phase swinging at high frequency or DC link can be somewhat forgiving if you run 70v or so but it's a different story when you go to higher voltage at 300A and abo...

The connector covers the contacts. Unless you submerge it under water, it will be fine.

I feel like the new signal connectors could be a weak point sticking out like that, especially with no electrical insulation. What if a couple drops of water make their way onto that connector?

It would allow getting things like location, battery state of charge, pretty much any info about a vehicle's sy...

Re: BESC-G4

Looking good. 12 gate drivers, one per mosfet? I was eyeballing SOT-227 for my build a couple years ago but it was a non-starter pricewise at least then. Ended up using TOLL package on metal substrate. Keeps it compact and cooling is direct through the board. Can't tell if you are using power isolat...

The enclosure is 225mm long, 78mm wide, and 51mm high. This is the compact/light version currently used but I also have a larger/heavier with more cooling fins. Compact is normally enough though as the cooling via IMS board is a few times more efficient compared to FR-4 boards. This enclosure has a ...

Re: PV NextGen FOC 130v 200/600A 25kw - $599, Watch Display

Yes, since we run current phase to phase, electromagnetic force is created on those coils when charging, so it moves just a tiny bit to align to magnets to reach an equilibrium position when the power source is connected. It feels like a little nudge, nothing too dramatic. As for the power limits, y...

Re: Nucular electronics - complete kit for ev! [beta]

There are many variables that will affect efficiency of the boost charger but as a rule of thumb, the bigger the difference between the input and output voltage is, the larger losses will be dissipated as heat. The wider the spread is, the higher the duty cycle needs to be to boost to the voltage to...

Don't take it too personal. The above stated is a common knowledge and is well documented in many sources like in the one linked. FW is a great technique but it needs to be put in a larger context for optimal use. Such as the type of the motor, safety/reliability/efficiency considerations, etc.
