Your Car
Small EV ≈ 4.0 · mid-size ≈ 3.5 · large SUV ≈ 2.8. Drops in winter.
Energy lost as heat during charging. ~10% AC home, less on rapid DC. This is why your bill is higher than battery size alone.
Charge level
Most people top up 20–80% rather than full charges — it's faster and better for battery health.
