Range, battery capacity and charging: what the numbers mean
Battery energy is measured in kWh; charging power is measured in kW. The catalog battery figure is an estimate and may not distinguish gross from usable capacity. EPA energy consumption includes charging losses, so multiplying it by range does not establish pack capacity.
Charging speed changes with battery temperature, state of charge, charger capacity and vehicle limits. A peak kW figure does not apply throughout a charging session.
