The range of an electric car depends primarily on its battery’s capacity. The bigger the battery, the greater the range. However, individually controllable factors as well as the car type (e.g., vehicle weight, efficiency of the regenerative brake and the electric motor) also have an influence on this.
The values provided by the manufacturer are linked to optimal conditions. In everyday life, however, the range is usually lower. Based on these factors, it can be influenced by the driver: speed, distance travelled, load, individual driving style and usage of electricity consumers such as air conditioning or heating.
The range specified by the manufacturer is determined through the so-called Worldwide Harmonized Light Vehicles Test Procedure (WLTP). Since September 2018, new vehicle types have had to undergo this test, which replaced the previous NEDC (New European Driving Cycle) procedure.
