Data from VW, Tesla, Renault: long-lasting electric car batteries >


Rechargeable batteries in modern electric cars may last much longer than calculated or determined in older studies, researchers in Munich recently wrote: Technological advances of recent years speak for it, and manufacturers certainly need more Will know the updated data, but will not publish them. So the team from the Technical University of Munich bought batteries from VW ID.3 and tested them themselves – and found that Efficiency at about 90 percent even after 160,000 km under extreme pressure lay. Soon after, Tesla reported similarly high values ​​after 320,000 kilometers for the Model S and Model X. And during the week Renault also provided reassuring-sounding data on the battery of its popular Zoe electric car.

Tesla 10,500 km. saves CO2 after

Such results have an impact on battery life or mileage that customers can rely on. However, they play a major role in determining the calculated CO2 emissions per kilometer over the entire period of use. Because most of this is produced in electric cars during the manufacture of the battery, and the longer it lasts, the lower the total emissions per kilometer. This in turn plays an important role Decision on the right funding policy for CO2 reduction in traffic,

For example, Tesla in its current impact report calculates that electric cars will be phased out after 320,000 kilometers in the United States and 240,000 kilometers in Europe. the reason is Show Model S and Model X data in the same report, it’s not like the batteries would be unusable then. But if one doesn’t take into account the potential long-term use in electric cars themselves or in stationary operation, a hypothetical mix of Model 3 and Model Y in the United States would produce less than a comparable combustion engine after just 10,500 km. Should cause CO2 emissions.

In Volkswagen, similarly longer usage times and thus clear electric car benefits should result if the Munich researchers’ results with ID.3 are confirmed and included in such evaluations. And with Renault, now another manufacturer has been added whose experience shows that the CO2 picture for electric cars looks overall more positive than previous figures.

Electric car Zoe . with battery data for Renault

99 percent of all batteries sold for Renault Zoe in Germany are still fully operational 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 52 kWh. So the dates go back a long way, because the first samples of Europe’s best-selling electric car in 2020 (see photo above) were already delivered in 2013. According to Renault, the minimum failure rate also includes vehicles that are already out of battery guarantee for eight years or a maximum of 160,000 km. Here too, neither customers nor climate defenders have to consider the fact that electric car batteries will quickly go flat afterward.
