· Bosch expects hybrid and electric vehicles to have a more than three percent share of the world market by 2015

Stuttgart – With its work to develop and subsequently manufacture automotive lithium-ion batteries, Bosch is rounding off its portfolio of products for hybrid and electrical drives. SB LiMotive Co. Ltd., its joint venture with its Korean partner Samsung SDI has started its operations in this area on September 1, 2008. “Thus, we are the first and only automotive supplier with a joint venture to develop lithium-ion batteries for the complex requirements of the automobile,” says Wolf-Henning Scheider, president of the Gasoline Systems division. In 2011, Bosch and Samsung intend to start production of battery systems.

“Apart from Bosch core competencies in automotive technology and Samsung SDI know-how in lithium-ion technology, the two companies will invest between 300 and 400 million dollars in this area in the next five years,” Scheider adds. Lithium-ion batteries are the key technology for the use of electric motors in vehicles. For more than 30 years now, Bosch has been working on electrical drive technologies for the automobile. This means that the company can draw on comprehensive expertise in battery, electrical drive, and brake management, as well as in engine management and transmission control. In addition, the company has already built up a broad portfolio of components, including powerful electric motors, the necessary power electronics, and DC/DC converters. Bosch’s main focus is the concept of the parallel hybrid, whose modular components can be customized to suit the requirements of individual OEMs and their models. Bosch already has its first orders for both gasoline and diesel hybrids. Besides mild and strong hybrid concepts, Bosch also offers simpler methods for innovative start-stop technologies and the recovery of braking energy via the alternator, as these concepts also allow significant CO2 reductions to be made. Within the Bosch Group, the expertise of roughly 370 associates from a wide range of divisions is pooled in a “Hybrid” project unit, whose purpose is to develop and market hybrid and electrical drives. A further 40 associates are involved in the further development and marketing of lithium-ion batteries.
