Lithium Ion Batteries to Power Mercedes Hybrid

Mercedes next year will begin producing the S 400 BlueHYBRID sedan using more efficient lithium ion batteries that are seen as the key to plug-in hybrids.

Daimler integrated batteries from Continental into the vehicle's climate control and electrical systems and will maintain a temperatures of between 15 and 35 degrees Celsius to maximize their performance.  In 2010 Mercedes will offer a diesel hybrid that will get even better fuel economy.

Since it is a luxury  sedan from Mercedes, it will probably cost more than $50,000, in Europe and the U.S.Lithium ion batteries are more desirable because of they can store more energy per pound than nickel-metal hydride batteries that have powered the first generation of hybrids. Diesel hybrids will cost appreciable more than gasoline vehicles, but the potential in fuel savings could pay back the added cost in a few years.

If Mercedes says lithium ion batteries are ready  for the street, then expect many other auto manufacturers to follow with plug-in hybrids.
