Series Hybrid CarThe manufacturer who backs this technology is GM. Their first effort at bringing this technology to the masses is the Chevrolet Volt, which was first unveiled to the public on 7 January 2007 at the Detroit North American International Auto Show. The car is the first-ever series hybrid concept car shown by a major manufacturer. The car has a 1.0-liter, 3-cylinder turbocharged engine that runs an onboard 53-kilowatt generator that recharges a 16-kilowatthour lithium-ion battery made of 80 four-volt cells. The battery pack takes a volume of 100 L, which is about 1/3 as the lead-acid batteries in 1990s typical electric car, the GM EV1. GM has stated that the battery is likely to last at least 10 years, through 4,000 full-discharge cycles. To see how the series set up works in the Volt, see spectrum.ieee.org/lithbat_flash.html
