What Goes Into an Electric Vehicle

The Chinese behemoth that makes electric-car batteries for Tesla Inc. and Volkswagen AG developed a power pack that lasts more than a million miles -- an industry landmark and a potential boon for automakers trying to sway drivers to their EV models.

Contemporary Amperex Technology Co. Ltd. is ready to produce a battery that lasts 16 years and 2 million kilometers (1.24 million miles), Chairman Zeng Yuqun said in an interview at company headquarters in Ningde, southeastern China. Warranties on batteries currently used in electric cars cover about 150,000 miles or eight years, according to BloombergNEF.
