Isn't that about the highest number anyone has seen? At this rate, you'll be over 50Ah by next May. Keep injecting that secret sauce!PV1 wrote:Might have been my car's deep sleep, but it now reports 46.1 Ah!...

Correct, PMC = Percentage of Manufacturer's original Capacity, so 78% PMC = 22% degradation. This assumes the battery pack has been in the vehicle for a while as the BMU needs a good bit of data to calculate an accurate battery capacity. Discharging to <2 bars (flashing) from a full charge and then a slow level 1 full charge will usually give the BMU some good data on the state of your battery, otherwise the BMU is making too many assumptions.
Multiply the Ah capacity by the pack voltage (330V) and you get kWh. http://www.evpositive.com/battery-history.html (that is for the PHEV which has a different pack voltage, otherwise all other comments are applicable)

This is after charging last night to "full".
Malm wrote:"The owner’s manual (around page I-4) states that we should have no more than 20% loss after 5 years." Is that loss of battery capacity or loss of range? 22% loss of capacity doesn´t mean 22% loss of range. This is because when new the car will let use only a percentage of total capacity, but with time it will increase that percentage, and after some time, we can use all the capacity available. In my experience, with 22% loss of capacity, the range will only decrease something like 15%.
Some owners even saw an increase in range after sometime, because of that. It happened to me and that is because I'm one of the rarest that could get 175 mRR.
