Ah, makes sense. thanks!The battery uses about 10.7 kWh maximum per full charge. The top 10% of the battery capacity and the bottom 15% is not used And remains a buffer which extends the life of the battery. .
If the full 14.4 kWh capacity was used, the 14.4 kWh battery would much more rapidly degrade each year reducing your all-electric range.
The extra 1 kWh you notice (11.7 vs 10.7) is probably the energy lost due to charging inefficiency which is typically greater with 120 volt charging.
