The battery test race to work out what used EVs are really worth
One of them is Altelium, a UK startup that has a developed an EV battery state-of-health test and certificate launching this year in more than 7,000 U.S. car dealers and over 5,000 UK dealers through dealer service providers including Assurant and GardX. Austrian startup Aviloo, which has developed a test for dealers and private individuals, has found that after 100,000 kilometres (62,140 miles) EV battery health can vary by up to 30%. According to EV battery tracking startup Recurrent, U.S. used EV prices in September were down 32% year-on-year, versus a 7% drop for fossil-fuel models.
