46 | Supplement 2 | Journal of Bosch History A future for electric vehicles Alternative drive systems from Bosch
Bosch Automotive | 47 Bosch is not just a leading supplier of diesel and gasoline injection systems. For over four decades, the company has been researching electric drives for road vehicles and, since 2010, it has been supplying solutions for hybrid systems, which combine an internal-combustion engine with an electric motor. The internal-combustion engine will remain the predominant technology in cars for private transport for many years to come. Nonetheless, engineers at Bosch are working to make sure that mobility also remains affordable when the electric drive displaces gasoline or diesel engines in cars in the future. With the exception of idyllic islands where internal-combustion engines are banned, electric cars have not yet become a common sight on our roads. But this situation is set to change in the decades ahead as the rapid pace of motorization, particularly in the fast-growing economies of Asia, makes the search for alternatives a must. Any new concepts must take environmental impact into account, as well as the limited supply of crude oil. The internal-combustion engine is currently still the most cost-effective solution in the market, and Bosch engineers are working on improving it further still. But they are also working in parallel on making the vision of electric driving a reality. They are focusing on three main areas. First, on developing and manufacturing high-performance lithium-ion batteries. For this purpose, Bosch has set up the SB LiMotive joint venture together with the Korean manufacturer Samsung SDI. Second, on improving the power electronic components. These components are the link between the battery and electric motor, and convert the battery’s DC voltage into the AC voltage required by the electric motor. And third, on pushing forward with the development of the electric motor itself, a key area in which Bosch has accumulated almost 100 years of expertise. A record-breaking start The history of hybrid and electric drives at Bosch starts in the 1960s, with research into all-electric drives. The first prototypes equipped with a Bosch electric drive were already being driven in 1967. On May 17, 1971, test drives in an Opel GT sports coupé on the Hockenheim Ring racetrack in Germany demonstrated the potential of the electric drive. The driver Georg von Opel immediately broke several acceleration world records. Technicians at the Schwieberdingen location near Stuttgart had developed the sports car’s power electronics and the two DC motors, each with an output of 44 kilowatts. The first large-scale trial with electric, zero-emission buses kicked off in Mönchengladbach as early as 1974. Widely acclaimed prototype In the case of hybrid drive – that is to say, the combination of an internal-combustion engine and an electric motor – the start of activities was marked by a research vehicle based on a Ford Escort station wagon. It was equipped with a series-produced gasoline engine and an electric motor that powered the vehicle up to speeds of 30 kilometers an hour. The alternator of the gasoline Left: Cockpit of the Ford Escort Hybrid. The production vehicle was converted by Bosch engineers in 1973. The first prototype of a hybrid automobile combining a gasoline engine with an electric motor, it made a great impression on the trade press. It could drive at a speed of up to 30 kph on electric power alone.
