surprising relation between fmax and speed rpm? ~14.6 [SOLVED]

Hello, this might be a quick and easy one, but I played with the rev limiter and was surprised by the fmax limit and then measured rpm: I expected (either/or): Hz * 60 == maxrpm Hz * 60 * 4 == maxrpm I measured: Hz * 14.6 == maxrpm. Where is my thinking wrong? Firmware is 5.18 on the inverter I test...

Re: Interference: How to measure and fix it?

I measured 12V+ to my VCU and scope ground to 12V battery ground to see the 17.6kHz waveform, that is one datapoint. The other datapoint is that the BMS does not report correct cell voltages while driving, no such problems when charging, and even when stopped at a red light it will recover and show ...

I've not tried this, but my first instinct would be to use an RTL-SDR with a directional antenna and wave it around... Thats great!

Re: Interference: How to measure and fix it?

That is a very good shout arber, the BMS position is indeed slightly different between our two vehicles. On a bigger scale though, how would I best go about measuring it? Maybe it is impossible, but I was hoping I could get some sort of heatmap after dragging a sensor across the vehicle, a bit like ...

Interference: How to measure and fix it?

Hello, I have seen the previous discussion here about a similar problem: (1) Now, I have interference at 17.6kHz throughout my low voltage system - double the 8.8kHz the inverter runs at, and only when it is active - checks out. Our setup: - Two battery boxes, one in the front, one in the rear. - Sh...

It works in a car, you see e.g. 60A for regen, -100A when pressing throttle harder, 90A when ChaDeMo etc. Just adding to 500ms made the display work, but it destroyed the web interface, hence having to add a second scheduler to be able to interrupt it, the code is blocking, so in 500ms it would also...
