Continental is set to start first-time volume production of a high-performance Li-ion battery for hybrid vehicles at the end of the year. The batteries will be used for the Mercedes S 400 BlueHYBRID,

"Li-ion technology is viewed as the key to the success of the hybrid and electric drive systems in motor vehicles offering a higher energy density, and thus a wider range, than those based on conventional nickel metal hybrid technology. The power output of the battery determines the overall performance of the vehicle as well as the potential for lower emissions and for possible fuel savings. In so far it also has a significant role to play in reducing CO2," explained Dieter Rogge, head of Continental's Powertrain division, which has developed and will supply the technology.

Aside from the Li-ion battery, Continental also supplies the inverter and the DC/DC converter for the Mercedes S 400 BlueHYBRID. The inverter controls the flow of energy between the electric motor and the hybrid battery. The DC/DC converter is the link between the hybrid battery and the vehicle's standard electric system and thus makes possible the elimination of the conventional generator.

Already since the mid-90s Continental has been developing components like power electronics, electric machines and energy storage devices for hybrid drives. As a hybrid system supplier not tied to an auto manufacturer, the company has, since 2003, been mass producing a mild hybrid. With the hybrid battery pack, the company introduces eco-friendly hybrid technology onto to the market faster and at a more attractive cost.

"This marks an important breakthrough for Continental as supplier of battery systems. In the next few years we will be launching production of further Li-ion energy storage devices for mild- and full-hybrid and electric-powered vehicles," says Continental executive board member Karl-Thomas Neumann.
