Re: LeafSpy..less than 100% at full charge?

My analysis using WattsLeft and LeafSpy (both developed by turbo3) suggests the charge to 100% ends at 4.09xx V and 80% at 4.02xx V. As turbo3 mentioned, the SOC decreases as the Leaf gets older, but the average voltage at which 100% and 80% set points (MY11 Leaf) occurs is close to constant.Turbo3 wrote:Keep in mind that SOC is not a direct indication of the energy in the battery. Just how full the battery is. As the battery ages it can hold less and less energy.
My 2011 when set to charge to 100% actually just charged to an SOC 91.71% but that is only 205 Gids or about 73% of the original capacity.
When new SOC was around 95% at full charge. So if you just looked at SOC change I have lost only 3.29% which is obviously not the case.
As a Leaf gets older SOC is of less and less value.
It does benefit Nissan as customers can not really see battery degradation in the SOC number now displayed on the dash. Someone buying a second hand Leaf would probably look at the SOC at full charge and think everything is still ok.
