Since I lost my top capacity bar, the SOC and GOM (DTE, sorry Nissan) instrumentation has been very pessimistic. Also, I am now getting more miles between LBW and VLBW than before. The net effect is that between 1/4 and 1/3 of my useable battery capacity is still available when I get down to 2 bars on the SOC gauge. The estimated time to charge has been affected to the point that it now underestimates charging time. Therefore, I think the errors in the dash instrumentation are leading you to inaccurate capacity loss calculations.
interesting. i wonder how many people have range anxiety needlessly?
