| Description: | Electric vehicle efficiency |
Vehicle efficiency is the energy required in watt-hours to travel one unit of distance (km or miles). This is a physical property of the vehicle and governed by factors such as electric motor and drivetrain efficiencies, friction and air resistance.
In the metric system this is measured in watt-hours per kilometre (Wh/km) and Imperial US it is measured in watt-hours per mile (Wh/m).
Efficiency concerns the motor and battery system only and is therefore unrelated to Charging Efficiency or Auxiliary Consumption.
As an output efficiency reflects the input value.
