The percentage is irrelevant, what matters is the charge termination voltage, which AFAIK is lower on all electric cars because you care about battery longevity. I.e. if the same cells were in a laptop, your car showing 100% might only be 80% in the laptop, and it's all good. (What the actual charge termination voltage [and cell type] is, I sadly don't know and don't know where to find…)
