Re: Renault Zoe (Continental) Inverter Reverse Engineering
Taking baby steps. I'm trying to figure out the position sensor which I expected to be a resolver. But it isn't. I have the wiring diagrams and there the pins are called - Ground - Supply (measures as permanent 5V) - Position Signal 1 - Position Signal 2 So I though ok, it must be some sort of posit...

Great, thanks! Are we just leaving the boot delay capacitor unpopulated? Yes or replace with 0.1uF, that's known to work from other boards Verify different 32 & 40 position connector footprints SMT is verified, through hole not because part is lacking If R1 is removed, the plan is to allow the b...

Re: Extremely low power and poor pedal performance
Oh, wow. So in effect the pedal will register WOT at that point and the rest of the travel is wasted? Yes Well for what it's worth, the Prius pedal on my Leaf OI board has a range of about 1000~3200 on channel 1 and 500~2800 on channel 2. The Leaf boards based on Mini Mainboard already have the 1:2...

Re: Nissan Leaf Gen3 Drop-in board
The Zener is not needed as the coded voltage is below 1.23V and brake light flicker can be software-avoided in any case.
Somewhere I concluded 3k3 is a bit high as it sits at 3V at room temp. For the sake of unification it could be lowered to 1k2. What else was there?

Re: Extremely low power and poor pedal performance
Great
If possible you can add at 4k7-10k series resistor between pedal and throttle input and redo calibration. Then you can use the full range.
No improvement possible on that front.johnsongt350 wrote: ↑Tue Mar 26, 2024 8:50 pm Any recommendations on giving the pedal a different set of parameters

Re: Extremely low power and poor pedal performance
That is (unfortunately) quite common with many throttle pedals. They range from 0.8 to 4.2V while the analog input ranges from 0-3.3V. Some newer designs have a 1:2 divider to be able to use the full pedal range.

Re: [DRIVING] VW Touran powered by Nissan Leaf [FINISHED]
Despite the replaced wifi module and despite giving the scheduler top priority the VCU restart happened again today. I almost have a hunch it happens after a fixed time now but that is very vague. The reset cause is IWDG, so watchdog reset. There'd have to be some exception or endless loop to cause ...

Re: Extremely low power and poor pedal performance
Your pack voltage is displayed as 333V and udcmin=320V . That is much too high. Set it to 250 or even 200V for now to take it out of the equation.

Thanks, had missed that one.
Still most visitors cars run on oil, some weird substance that I can't produce at home
That said, for me personally there will be no point in using a custom charger once I've done the 11 kW MG upgrade

LIN based CCS
Just an idea... If we want to build some personal DC chargers it is kind of bulky to equip them with the PLC stuff. So been thinking to run LIN over the CP line. Wasn't that even Teslas take on their V1 superchargers? So as an option, say the PP resistor has value x then we change over to LIN comms....

Re: [DRIVING] VW Touran powered by Nissan Leaf [FINISHED]
I wasn't even aware these existed. But rear window heating works and also power steering. Power steering just checks for motor rpm, that's why I simulate idle speed of 700 rpm. Maybe heated window does the same?

Re: Parallel Onboard Charging?
Ah, no solar doesn't need rectification
So then both input voltages are floating anyway. Not sure about regulation. It is a current controller so it will keep increasing PWM until current is reached. No MPP

I've never tried paralleling these booster converters but I find it pretty cool that you're using the facility in the first place
You could run them off a common rectifier pre-empt any phase troubles

How far can you increase throtcur before the inverter trips?
500A battery might be asking a bit much from a Prius inverter
EDIT: can you also post screenshots of spot values while the motor is running at full power, please.

Ok, slowly. Do you get valid position feedback when turning by hand? Are you sure about the number of pole pairs of both sensor and motor? Have you checked the waveform of the sensor to be within 0-3.3V? What is the midpoint (min+max)/2?
