Rechargeable batteries in modern electric cars may last much longer than was calculated or determined in older studies, Munich researchers recently wrote: Technical progress in recent years speaks volumes about this, and manufacturers are sure to know more recent data, but not publish it . So the Technical University of Munich team bought VW ID.3 batteries and tested them for themselves – and found that Capacity even under extreme stress after 160,000 km is still around 90 percent extend. Shortly thereafter, Tesla reported similarly high values even after 320,000 kilometers for the Model S and Model X. During the week, Renault also provided reassuring data on the battery of its popular Zoe electric car.
Tesla conserve CO2 after 10,500 km
These results affect the battery life or mileage customers can count on. However, they also play a major role in determining the calculated CO2 emissions per kilometer over the entire period of use. Because most of it is produced in electric cars during the manufacture of the battery, the longer it lasts, the lower the total emissions per kilometer. This, in turn, plays an important role in Decision on the correct financing policy to reduce carbon dioxide in traffic.
In its Current Impact Report, Tesla, for example, calculates that electric cars will be phased out after 320,000 km in the United States and after 240,000 km in Europe. The reason is like this Show Model S and Model X data in the same reportThis does not mean that the batteries will then be unusable. But even if one does not take into account the possibility of longer use in electric cars themselves or in stationary operation, a fictitious mixture of Model 3 and Model Y in the US should emit less CO2 after only 10,500 km than a similar combustion engine.
At Volkswagen, similar long periods of use and therefore more obvious advantages of the electric vehicle should emerge if the results of the Munich researchers with ID.3 are confirmed and included in such evaluations. With Renault, another manufacturer has been added whose experience indicates that the CO2 profile for electric vehicles looks more positive overall compared to previous data.
Renault with battery data for ZOE electric car
99 percent of all batteries sold for Renault Zoe in Germany are still fully functional and have at least 70 percent of their original capacity, The company announced on Tuesday. This applies to the first generation with a capacity of 22 kWh as well as the current generation with a capacity of 52 kWh. So the dates go back a long way, because the first samples of The best-selling electric car in Europe in 2020 (See photo above) Already delivered in 2013. According to Renault, the minimum breakdown rate also includes vehicles already outside the eight-year battery warranty or a maximum of 160,000 km. Here, too, neither customers nor climate protectors have to realize the fact that the electric car battery will quickly become empty afterwards.
