Yes, that's right, lowering the temperature by 5 degrees to match the ambient temperature can take approximately 15 hours. This graph, which assumes a mass of 500 kg, can serve as a reference. For example, assuming a garage with a constant temperature of 15 degrees, if after 10 hours the...

Without BMS intervention, the temperatures should be the same after a few hours. A few degrees difference means energy is being added for cooling or heating. How much? I don't know. I'll continue testing for a few more days and will report the results.

Ok. Did you notice any difference between the ambient temperature and the battery temperature?

One question. When your car has been parked for a few hours, does the outside temperature match the battery temperature?

My guess is that the activated battery conservation function forces the car to "wake up" the BMS more frequently to check the battery status. This will result in energy consumption. It's well known that low temperatures are also detrimental to long-term battery health. The owner's manual only...

I think I have good news, although it needs confirmation. My Macan belongs to the club that loses 1% of its charge daily. Or maybe not anymore. In the past, I tried a bunch of things to figure out the cause: I disconnected the dashcam, I didn't connect to the app to check the status, etc. Same...

Besides the charging voltage, does anyone know if the 12V battery bar graph indicates anything about the battery's health? I've never seen it at 100%, only moving around 75%. I couldn't find any help in the user manual.

I did a small experiment. For some time my SoC has been losing about 1% per day. I started to suspect the 12V auxiliary battery. OK, I didn't plan on using the car for three days, so I connected the smart AGM battery charger and left it on for about six hours until it reached 100% (it started at...

Renault may be very efficient, but I still have a doubt. The SoC that cars usually display is calculated using an algorithm (just like the range indicator), and each manufacturer/engineer does it differently. The only known way to determine the capacity of an EV battery is by charging "x" kWh...

Yes, that can work. Activating the car's turn signals/horn also works. But be careful, this will wake the car from "sleep" mode and it will consume a little more energy. Anyway, I don't want to make a big deal out of this. 1% = 1 kWh can mean €0 if you charge with solar panels, or €0.06 x 30 =...

Yes, sorry for the typo (SoC) I don't want to start a debate. If someone thinks an EV doesn't lose energy over two weeks, good for them. That's not the case with my car, and I don't think it's the case with most others either. There's a lot of information out there about other EVs, but for...

Yes, that's right. The information usually updates when you unlock the doors. Although sometimes it doesn't. The most reliable way to check the SoC is to sit in the car and start it.

Sorry @Petzi, but you shouldn't look here. You should look here. Anyway, forget the app. To check the SoC status, you have to unlock the car, sit down, and start it. One thing's for sure: the car consumes energy while stationary (all cars do it, even ICE cars). How much energy? I don't...

As I said: (The app is useless for verifying this data because it doesn't update the information until the doors are unlocked. You have to open the car and check the SoC.) I'm not saying that a 1% daily loss is normal, at least not without supporting data. But I can say that a 0% loss is not...

I think there's a lot of misinformation about how our cars' batteries are managed. Neither Porsche (nor any other brand) provides details on how the battery is managed and the power consumption of its various components. It's truly outrageous that this information isn't provided to the rightful...
