Battery Capacities:
1. Design Full Capacity - never used, no real way to tell, so not very important in day-to-day use.
2. Allowed Capacity - the part that Nissan allows us to use
3. Wall Capacity - the amount of energy required from the grid/wall/EVSE to charge the battery (maybe 26 kWh)
4. Charging Energy - after the losses in the LEAF's internal charger, the DC energy that is actually delivered to the battery pack (maybe 24.6 kWh, just a guess). The charger's efficiency is not usually as bad as people say.
5. Stored Energy - after modest cell heating and small chemical losses during charging (or Regen), the amount of energy that actually gets stored in the battery (maybe 24 kWh). The charger often gets blamed for this loss.
6. Recovered Energy - the real usable energy, significantly less than the Stored Energy (maybe around 21.4 kWh). Regen energy, stored in the battery for later use, also suffers this loss. This is the most often overlooked energy loss, and the source of much confusion. The cell-heating losses can be substantial, depending upon the rate of energy extraction from the battery - higher power drain usually means a higher percentage of heat losses. There would also be some small chemical-process losses, and some self-discharge losses. Finally, cell equilization might have removed some energy from the higher-charged cells.
8. Motor Energy - the energy used by the motor, after inverter losses. This "energy" is sometimes used to display "inflated" miles per kWh figures.
So, depending upon WHICH energy you are talking about, you are all (almost) correct.
