Re: I think I CAN, I think I CAN...
2. few years back, I had problems with those ali boards too. Ended up replacing SN65HVD230 chip with SN65HVD234 and it worked OK.

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion
Thanks you guys very much for explanations... I did some reading and came to the same conclusion. I've also seen that 33R is common in conversions. My initial plan was to use DMOC 665 inverter but that failed. Since I had that at table, I've used precharge resistor from that inverter and that is whe...

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion
Can someone help me with pre-charging? I want to shorten my pre-charge time, as I think it takes too long to get to the referent voltage. Battery pack is 96s and it's sitting at 366V. I use 10kOhm 25W resistor (big one with radiator) to do pre-charge. When I connect my resistor across, measured volt...

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion
Very impressive numbers! I'm interested in your battery details, do you mind sharing some numbers (volts, number of 18650(?) In each box, kWh?,...)? And what is the BMS you are using? Thanks and good luck with the rest of the project! Check previous posts for more details... This is cell info INR18...

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion
Another test run with latest v5.26.Y firmware... Some logs and parameters attached.
I'm very pleased with performance and probably will leave it as is for now.

Re: ESP32 Based Web Interface & Data Logger
My branch is https://github.com/mmadzar/GN02475inv and inverter firmware update code wasn't changed, just added some custom code that no one else needs. :) I can confirm that firmware update code works. I uploaded v5.26.Y firmware last night without any problems. Just uploaded bin file and that was ...

Re: Current control of induction motors
Thank you very much for testing! Great to hear this works on the Prius and you're getting smooth results! I look forward to seeing more details. Thank you. :) There will be no test for some time, as I plan to put car on the stands again and finish everthying that's left. It's not very important but...

Re: Current control of induction motors
Last night I've updated my Prius Gen3 with latest code from https://github.com/catphish/stm32-sine/tree/amp branch - v5.26.X I did change few of the parameters and will post later in the project thread... But, with this firmware it was easy for me to find limit and avoid inverter shutdowns by just a...

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion
120 kW with Prius, wow! Is that with power stages paralleled? What's the system voltage? Nope, no paralleled stages, just MG2. Battery is 96S and this test was not with full battery, voltage was something under 370V. Voltage and current are measured using ISA shunt and this 120+ kW is from the batt...

Re: BMW e39 + Siemens motor + Prius Gen3 OI - Yanoibe39 conversion
I want to share some logs from my last test drive... Inverter has v1d board and 5.25.R-sine firmware and I used parameters available online both, for inverter and motor, with minimal changes. I have parameter sinecurve set to Simultaneous. Road is only about 200m long so not too much space for testi...

Re: ESP32 VCU development
Yes the idea is to replace the module with the clear ESP32 chip in the end. I need to know which pins i can trust and what would actually be better BLE or Wifi. I am really impressed by my BMS ability to connect via bluetooth showing all the cells and data... I did some programming of the ESP32 dev...
