I may be misinterpreting the actual data, but if I take the 50.25kWh battery energy and divide it by the SOC (state of charge), I get 79kWh of total battery energy at 100%. I am getting the same reading on my 'repaired' battery where two of the cells were replaced. My total battery energy according to Porsche should be 93kWh. It looks like these figures for some reason are not indicating the total battery energy - is this the case?@ciaranob . I hadn't looked for the SoC True in a while. The location was changed but it's there. You can see it in the graph in the center of the first screenshot.
The first/main screen shows SoC Display and HR and today they are pretty close. SoC true reads higher at 63.65%. Someone, somewhere deep in the bowels of Stuttgart probably knows how the different readings are derived and what they represent but I suspect we mere mortals will remain in the dark.
My understanding is that "full" available battery capacity is 86.7 kWh when new (despite Porsche's published spec). The difference between that figure and the 93 kWh is the buffer. If you sort of work backwards from my screen shots: 50.25 kWh battery energy @ 63% SoC = 79.76 kWh theoretical capacity at 100%. At a SoH of 92.33% that works out to 86.4 kWh for my battery new (easily within rounding from 86.7). If you do the same calculation with your current SoH you should arrive at an original available capacity of 86.7 kWh.
I have not had much time to drive the car, but have charged it once up to 80% so no new data really. I also believe that it will change when being used more and charged with both AC and DC, which will occur in the next couple of weeks, all going to plan. So far my total capacity would indicate about 87 kWh and that is not correct with only two modules being changed
It will be interesting to see where you wind up on SoH in a couple of weeks.
