EV
kWh (kilowatt-hour)
The unit for EV battery capacity — bigger number means more range.
A typical small EV (BYD Dolphin) has a 44 kWh battery; a long-range Tesla Model 3 has 82 kWh; a Ford F-150 Lightning has 131 kWh. Real-world range is roughly: battery kWh × 6 km/kWh (efficient sedan) or × 4 km/kWh (heavy SUV/ute).
