I got a different impression from the wording of the SOC discussion under Simple Summary. It sounded like the SOC readout followed the battery energy potential (capacity) as it as it declined over time.

Here is what the Help file says:

Code: Select all

`SOC = State of Charge: This is read directly from the Leaf and is based on the current capacity of the Leaf battery. That means if you charge your Leaf to 80% then SOC will always equal 80% at the end of the charge even after 8 years when the battery capacity has dropped to say half its original capacity. It is not an indication of the energy contained in the battery.`

I am not sure if your statement "readout followed the battery energy potential (capacity) as it declined over Time" means the same thing as what I wrote in the Help file.

Another way to look at the Leaf SOC is to think of the battery as a gas tank. Say new the tank holds 10 gallons and we fill to 80% so it now has 8 gallons. Ten years later the tank (battery) has degraded and now can hold only 5 gallons. Now when you fill to 80% it only holds 4 gallons. SOC in both cases is 80% but the amount of gas held is only half as much since the tank has shrunk over time.

Over the long term SOC can not be used to indicate how much energy is available from the battery. It only indicates how full it is relative to its current capacity which decreases over time.
