I switched off all the lights and have a bit of blanket blocking the lock so I can close the tailgate without it locking. I can confirm that there is NO voltage left in the 12V bus after removing the battery negative. In the time it takes to walk to the front and measure the voltage on the...

The 12v filter capacitors can usually store energy for a second after power down and mostly longer as MCUs usually crash below 2V. Writing this small amount of data even with an ancient 4MHz clocked MCU would be a matter of less than 100µseconds. The MCU's watchdog brownout detector will...

If I wait until 4 relays clicks, charger will not start charging. If hold a second longer than the 4 clicks, there are 2 more clicks in the car in short succession and the charger's 'Charging' LED goes on. Maybe the problem is a delay of the response time in the charger and we are using...

76% SoH at 60,000km in my case does not give me reason to believe that I will get anywhere near 130,000km. ...and I am reading similar cases from others, on this forum and elsewhere. Maybe you mostly drove soon after a full charge so that it rarely stood around at 99% SoC. No 8 year warranty...

Thanks elm70, I thought that could happen, won't built a switch for the fuse wire. But the fuel tank sensor, might get my attention one day. Pretty sure it is not too hard to emulate an empty tank to disable the ICE and then an increase of 15l is automatically given when the sensor is connected...

Ahhh a pure EV mode, naughty boy :) I am a PHEV newbie, still have a lot of tricks to learn. Maybe wire in a switch in series to the fuse connection for an EV Drag-mode(when fully charged) :mrgreen: I have a lot of blank switch spaces because I got the simpleton version. That doesn't harm...

Wow michalsarna, good job filtering out those relay clunks :) I tried a few times before you send this image, trying to get it not to show any charge display but to no avail. I had to go places and had no time, couldn't even finish the charge. I assume you mean the red plug-in symbol in the...

... and please post the link of your video here. Did you hear any relay clicks after the ESVE kicked in while you were still counting? Maybe from three relays normally required, only one or two were activated. I am starting to think that this has nothing to do with discharging capacitors to...

My point is that the battery does not wear out under these conditions, it could last for decades like that! I trying to prove that a battery that is used purely in EV mode, cycled everyday, can only last 60,000km when it's SoH drops below 80% and probably at 90,000 km it becomes so weak that it...

Scotty, I don't quiet understand what you are doing. How to you get the discharge values down to 20% ? Are you driving ? ...or what load are you using?

...but not cycled. It get charged to a certain level and basically stays there and not drained to 30% and back to 100% every 45km.

I agree with elm70 that logging while driving is extremely variable and difficult to make conclusions. I can not find original discharge curves for this battery to compare the voltages and DoD. SoC is not a useful parameter for these graphs as we need to see the voltage after how much energy we...

I never mentioned ABOVE 4.1V. It is common knowledge that if you keep a Li-Ion battery 10% below it's rated full charge it cycle life can increase by 50% and more. I have experienced that with many battery setups. Never heard of an ideal voltage. SoC is a confusing value as you can not predict...

No change for me either, ...well not quite, more about that below :) I want be as detailed and specific about this as possible so we can get to the ground of all this, ... hope I don't bore you guys, ... aah come on, geeky details are cool :) My 2014 PHEV has around 62000km, which I consider...

Charging it too often so it stays more often at 4.1V is a lot worse. It is possible that at 3.6V a lead footed driver will bring the voltage momentarily down to 2.75 but the ICE will kick in before that. Not sure why hybrid mode is a problem, the ICE is generating electricity and keeping the...

Could you provide the name or link(leaving out the http:/) to that forum?

After charge has started and 12V disconnected again, the green park lock light next to the shifter stays on. Car is locked. Is that normal? I never charged at night perhaps I didn't notice. Alarm LED blinks like normal, hope it doesn't go off in the night because the 12V from the charging...

Will do :) Finally somebody posted useful information on the comment section of the Youtube link in the first post just an hour ago, scroll down to sportster999, who claims after the procedure you can use the battery down to 3.6V and yes I agree, that is perfectly fine. 10kWh charge instead of...

Had my neighbour drive it to --.-- km. Very tiny bit left on the battery symbol. Crawled out of bed to measure with a dizzy head. Watchdog reads with handbrake pulled and selector in D and head lights on: 3.825V Cell difference is 0.011 and NOT 0.005, so I wonder if the BMU and ECU are...

3.85V showing empty, that is outrageous ! Below is the typical discharge curve of Li-Ion batteries from a reliable source and we are looking at over 60% SoC here: https://batteryuniversity.com/index.php/learn/article/lithium_based_batteries I am having difficulties finding discharge curves for...
