Thanks for the data Felix! It matches the PHEV data much better than the other discharge graphs I was using. Here is a discharge from above with your discharge included.

Ordered the driver and Nikolay responded very quickly. I have only read the BMU data so far but there has been no compatibility issues with a genuine tactrix openport 2.0 and x64 windows 10.

This is what I have been trying to create, attached are three graphs using a compilation of multiple data logs from a PHEV, creating a full discharge curve that lines up reasonably well to an iMiev discharge. I included both minimum voltage and maximum voltage curves to show the variation...

That's great news, I already have a tactrix to flash my RX8 ecu.

So I was able to log a fairly constant discharge using the heater and the fuel pump fuse removed again, but still not getting down to the voltages that some owners are seeing after resets. If anyone has any logs where the car goes into turtle mode or similar after a reset it would help target...

Thanks for the data points obiuquido144, that drops off really quickly at the end. If it still thought it had 0.8kWh left when it was empty, looks like there's closer to 35Ah left in your battery. What value did the DBCAM calculate after it charged? The voltages you have are higher than the...

So I have tried a couple of times to log data while charging and both my OBD adaptors disconnect, so no luck there. EDITED with latest data Elm70 mentioned voltage at rest, mine was sitting at 305.8V after 2 hours at 25.4%. My battery SoH dropped recently, it is now 76.6%, and this is...

Does anyone have some log data they would like to share? I found the quality was best with in town driving where it passed through different discharge rates often. My temperatures have been 15°C to 25°C so comparable temperatures would be most useful but I have the discharge curves for colder...

As to the cycling during hybrid mode, this causes less degradation at 30-35% SoC than if it is cycled from 95-100%, as the cell is under much less stress while discharged. The same reason that only charging to 90% provides cycle life increase >10% so if you can spare the range and inconvenience...

I removed the fuel pump fuse and drove it to 20% recording voltage at light load. The PHEV reduced power here to prevent further discharge of the battery, but if it is underreporting SoH then this will really occur at a higher point on the battery discharge curve. I added a 33Ah capacity...

Thanks both for your input, good to be getting more ideas. MadTechNutter, I had seen that pdf a while ago and originally used that for my voltages, but went with the iMiev discharge curve as it didn't contain the dip around 20 percent. I reread the document and it really suffers in low...

Thanks elm70 for the feedback. I agree to both of those points and to minimise it I have done the following. Load - I am only taking lightly loaded data points (coasting in B0). When you start coasting the voltage bounces back quickly then slowly increases from there. I am using a lightly...

Hi all, I have been following along with the battery degradation discussions and was curious of the battery voltage during discharge. I was recently in cold weather and the engine didn't start properly, on the short drive to the petrol station I lost significant power but unfortunately wasn't...

That's a good point, I thought the i-Miev was lower power. The PHEV is pushing the cells harder if the pack is only 12kWh compared to the i-Mievs 16kWh.

Thanks for the photos Esparza. I know they aren't ideal for measurement purposes, but I get roughly a cell width 20% of the length on the top image, and using the centreline for the bottom image I get a width 25% of the length. Scaling on the assumption the threads are the same size the lengths...

Finished charging a short while ago. EvBatMon data Capacity 33.2Ah, 87.37% SoC 32.9Ah, 99% Voltage 327.6V Cell Voltage Min 4.09V Max 4.10V Temps Min 28°C and Min 32°C IR Max and Min 1.5mOhm Power output in Ready no aircon - 0.33kW

Here's some data from today. Range was down to dashes and the car sat for about an hour before I could measure it. 2014 base model, 37,245km and 3.98L/100km total since new. EvBatMon data Capacity 33.2Ah, 87.37% SoC 9.5Ah, 28.5% Voltage 306V Cell Voltage Min 3.82V Max 3.83V Temps Max and Min...

I would assume the PHEV has a cell designed specifically for a PHEV application, being a cell that trades off energy density for power density. PHEV applications go through significantly more cycles and faster average charge/discharge C-rates than most common EVs, so need to be manufactured to...

Ours will sometimes detect the key as being inside the car when you stand outside at the drivers door with the key in your pocket. When this happens the button on the door handle doesn't work to unlock, and if you are trying to lock from this position it beeps at you that it's still in the car...

No we decided against purchasing roof racks to keep the car reasonably aerodynamic, just packed the boot well.
