How we calculate the range
The range is the quotient of the available capacity of the battery and the power consumption. The power consumption depends primarily on the driving speed. According to the international consumption measurement procedure WLTP (more on this under the next heading), an average of 46.5 km/h is calculated. Driving faster or slower on average shortens or extends the range.
In addition to the cruising speed, the individual driving style also affects the range. Allegedly “sporty” acceleration drives up consumption. Relaxed, anticipatory driving, on the other hand, saves electricity. Experience shows that hectic driving reduces the operating range by at least ten percent compared with the WLTP value, while wise foresight extends it by up to five percent.
The outside temperature also influences battery performance. If you demand full power from the drive battery even in summer heat, you shorten its service life. Added to this is the power consumption of the automatic climate control system. The colder the weather, the less power the battery delivers. If you also switch on the heating, the range quickly drops to two-thirds of the WLTP value. The battery is also cooled or heated as needed to keep the operating temperature in the green range.
The calculated range cannot be used to predict an exact realistic range, but it does provide a good feel for the factors affecting the range and the differences between the e-vehicles.
