Nearly all board computers of commercial electric cars give nice values when displaying the power consumption - sometimes up to a quarter less!
It could become a scandal that could permanently damage the reputation of electronically powered cars. Electricity consumption often plays a very important role when considering the purchase of an electric car. However, this is precisely where the manufacturers generously embellish and apparently deliberately deceive, as studies by the automobile club ADAC now confirm. Board computers of electric cars, for example, only show the consumption for the drive, but the losses during the charging process are not taken into account. Depending on the make, the deviations range from 10 to a whopping 25 percent: figures that make customers who think they are on the safe and "green" side when buying such a vehicle feel insecure and angry. Such reactions on the part of buyers are not surprising, given that the electric car is the much-vaunted saviour that makes an active contribution to climate protection. The "attempt to whitewash the car, commonly known as simple (deliberate) fraud," which has now been uncovered by the ADAC, could be the next low blow for the staggering car industry after scandals like Dieselgate. Incidentally, the front-runner in the misrepresentation of consumption is the pioneer of e-vehicles, the US company Tesla (24.9%), followed by Seat (20.8%), Renault (19%) and Nissan (17.6%). But companies such as Mercedes, VW, BMW and Jaguar are also to be found in this illustrious list, which reads like the who's who of the car industry.
In order to provide potential car buyers with a fair and complete overview of the respective power consumption and, last but not least, to restore confidence in the entire industry, the ADAC is now calling for the transparent listing not only of consumption values but also of the percentage values in the event of loss of charge, for example. Besides efficient drives, low-loss charging systems are also in demand in the electrical sector.
