Bosch and CATL plan to develop battery cells together
Bosch and Contemporary Amperex Technology Co. Limited (CATL) announced an agreement to jointly specify high-performance battery cells. CATL will then design, develop, and manufacture these cells in accordance with Bosch requirements. The cells are to be used in the 48-volt battery developed by Bosch.
Said Dr. Stefan Hartung, Member of the Board of Management and Chairman of the Mobility Solutions business sector, “With CATL, we have brought an established cell specialist for lithium-ion batteries on board as a partner. In combination with our systems know-how and expertise in battery management, we will extend our strong position in the 48-volt battery market.”
Bosch’s portfolio for 48-volt systems extends beyond the 48-volt battery to encompass other system components such as DC/DC converters and electrical machines. With this technology, Bosch aims to gear up all classes of vehicles for future emissions requirements. Its 48-volt electrification augments the combustion engine with an electric motor. This motor is powered by the 48-volt battery, which in turn is charged by recovering energy expended during braking.
Bosch expects that by 2025, nearly 20% of new cars sold annually around the globe will have a 48-volt system and matching battery on board. Demand for 48-volt systems is rising, especially in Europe and China.
The Bosch plant in Wuxi, China, started making the first generation of the 48-volt battery late last year. The USP of the latest version of this product is that the battery is compact and cooled passively. This means that automakers can simply integrate it into their vehicle models, and do not require any additional cooling units. In addition, Bosch says automakers can dispense with the long and costly effort of proprietary engineering work.
