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 massproduced 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.
