The battery of an electric car, just like that of, for example, a smartphone, slowly deteriorates. The full capacity can only be used at the beginning, after which it decreases step by step. That is why the European Union, among others, wants guarantees to be given for the lifespan of an EV battery.
Whether an electric car is really sustainable depends, of course, on how long you can use it for. Of course, that largely depends on the battery life. Several car manufacturers already give guarantees for the life of a battery. Take Tesla, for example, which guarantees that the battery will keep 70 percent of its capacity over the first eight years or 240,000 km for the Model S and Model X. With the Model 3, depending on the version, that is eight years and 160,000 km or 192,000 km. The European Union wants to see such a guarantee for all electric and hybrid cars.
Among other Automobilwoche reports that this has been agreed at the UN World Forum for the Harmonization of Vehicle Regulations. The European Union, as well as the United States, China, the United Kingdom, Japan and South Korea, have reportedly reached an agreement. Under the bill, car manufacturers must guarantee that batteries may not lose more than 20 percent capacity in five years or 100,000 km (whichever comes sooner). After eight years or 160,000 km, the degradation should not exceed 30 percent. There will be another national ballot early next year and it could be implemented in the countries that agree to it by 2023.
