- Charging losses: energy drawn from the socket is higher than what reaches the battery (charger, cables, battery heating). AC charging at low power has the highest relative losses.
- DC fast chargers bill the energy delivered at the charger, so only in-car losses apply. Petrol CO₂ is tailpipe only (2.31 kg/L).
