Selbstentladung
Zitat von Monstertom am 20. Februar 2025, 08:45 UhrWenn die Daten von einem OBD-Dongle kommen: Könnte der die Ursache sein, dass Steuergeräte nicht einschlafen, und es so zur Selbstentladung kommt?
Hatte ich in einem Renault Avantime auch mal...Viele Grüße,

Zitat von Imortem am 11. Dezember 2025, 22:57 UhrIn my experience you only loose SOC when some device didn´t get sleep. This happens sometimes (every few month), but then i could see the LED-Parkinglight is always on.
In this case i left ca. 3-5 percent a day. It helps to disconnet the 12V-Battery, then the car slept correctly and didn´t loose SOC anymore.
The other case may be if the 12V-Battery ist broken, i bougth a new on some days before. (I have my car 4,5 years)
Without reason and without any lights in the car, i lost in 1 week ca. 40% SOC. After a battery-change it was ok again.

Zitat von raico am 16. Dezember 2025, 16:25 UhrI think it’s actually not a real loss of SOC, but rather that the system doesn’t show the correct SOC while driving. I believe that when the cells are hot, the BMS is more optimistic, and then when they cool down, the real SOC is recalculated. It’s not shown on the display, but it gets recalibrated during the first few kilometers.
What I would have liked is for someone with an OBD to be able to check whether this also happens to them.
