Original Abstract

The work deals with the quality of batteries in electric vehicles manufactured today’s and the determination of warranty conditions and guarantees for built-in lithium batteries. However, the design, testing, prototyping and creation of new vehicles is not without errors, as the experience of some manufacturers, including the more inexperienced Mercedes, shows now. On a tested sample of the Mercedes E350e PHEV, a capacity loss of more than 30% from the original nominal value was measured after 18 months of vehicle operation, well above the manufacturer's expectations and declarations. After the first practical results on the quality of mass-produced EVs, the manufacturer removed all or part of the physical parameters of the battery (nominal energy) and introduced general warranty rules for the battery - limited by the number of years or mileage.
