kgkWh

kgkWh refers to a unit of energy consumption commonly used in the context of transportation, particularly for electric vehicles. It is a combination of kilograms (kg) and kilowatt-hours (kWh). This unit aims to provide a standardized way to compare the energy efficiency of different vehicles by considering both the mass of the vehicle and the energy required to move it. The underlying principle is that heavier vehicles generally require more energy to accelerate and maintain speed. Therefore, a vehicle with a lower kgkWh rating is considered more energy-efficient, as it uses less energy per unit of its mass. This metric can be useful for consumers looking to understand the operational costs and environmental impact of vehicles, especially when comparing electric cars with different battery sizes and vehicle weights. It allows for a more nuanced comparison than simply looking at kWh/100km or miles per kWh alone, as it factors in the vehicle's physical dimensions and weight. The calculation typically involves dividing the energy consumed (in kWh) by the vehicle's mass (in kg).
