It was never brought out to this pin. But it's not very useful anyway since it runs at a fixed frequency and variable duty cycle.

Quite simply the curve of the temperature sensor was never measured and programmed into the firmware.

Re: Renault Zoe (Continental) Inverter Reverse Engineering

Spied the "comms" with the DC-DC converter today by sandwiching a breakout board between stock logic board and DC-DC converter. It is mostly static voltages but there is some rather strange comms going on. On one pin the logic board sends an 11.2 MHz clock, on another a 2.8 MHz clock at 1....

Re: Brake servo Vacuum hold time.

On Touran the vacuum is still there the next day and the pump only comes on when touching the pedal.
On Audi the pump comes on every 30s and is now causing issues. Either the motor current draw is increased or the switching FET is overheating

Re: Replacing the VW BMU aka implementing high level BMS functions

variable for battery ah is all that is needed and as we can record ah used (from shunt) this value can be manually updated every few years or so Did a charge from 43 to 82% today or 60 Ah. I've set the capacity to 155 Ah (nameplate is 158) and indeed SoH calculated as 99.3% :) So 155 seems appropri...

Re: Switched ADC BMS

The max voltage per board is about 70V so I don't think that is any constraint. I used some sort of Molex connector. Couldn't really find that at JLC but there should be some sort 0.1 inch available.
I don't recommend wire-to-board because you don't want 17 live wires dangling about when disconnected

Re: [WIP] Mercedes 310E (310D campervan) - GS450H/GS300H

The blue one is the LEM HTFS, 5V supply, output centered at 2.5V. The other ones I don't know. You need to figure out which are the supply voltage pins, e.g. with a 50 mA current limited 5V supply. When a third pins spits out around 2.5V you've nailed it. Some are asymmetrical centered at 3V or some...

I will also need a car like this on the motorway and a minimum acceleration from 50 km/h is necessary. Just saw this. Not sure if I get a chance to do that as the car is now far away. Thomas uses it on the motor way every day so and never reported it was too slow on the ramp. It is slow in EV terms...

Re: Foccci wakeup/sleep discussions

The EVSE should shut down CP (or make it 12V) when setting current limits below 6A. Or and least when sending an explicit stop command. In that case you'd omit PP wakeup. CP wakeup is always active. So basically go with the 3rd approach from here https://openinverter.org/forum/viewtopic.php?p=69417#...
