How Bosch drives the development of the connected and the electric car

August 28, 2017 // By Christoph Hammerschmidt
The largest automobile show in the world, the IAA in Frankfurt, throws its shadows ahead. Electronics supplier Bosch shows already now where the journey is going

At the show, Bosch will focus on three topics. Not a big surprise: Technologies for the electrification of the powertrain, for automated driving and for the integration of vehicles into data networks - with extensive cloud services in the background - will dominate the company’s exhibits.

One of the company’s most strategic innovations will enable car designers to make electric powertrains more compact, more reliable and more affordable. Bosch’s electric axle (e-axle) is a compact, cost-optimized solution for the electrical drive of battery-powered vehicles and hybrids. The electric motor, power electronics and transmission are combined to form a compact unit that directly drives the vehicle axle. This reduces the complexity of the electric drive and has the potential to shorten the development times of electric vehicles. The e-axle features a variable design: Scalable for performances between 50 to 300 kilowatts, it can be installed in small passenger cars, SUVs and even light commercial vehicles. Its high overall efficiency results on the one hand from continuous optimization of the electric motor and power electronics, on the other hand from the reduction of interfaces and components such as high-voltage cables, plugs and cooling components. This translates into a higher driving range before the battery needs to be recharged. In order to guarantee fast and global availability, Bosch has developed a flexible production concept that is ready for use worldwide. “With this design, Bosch is applying the all-in-one principle to the electric powertrain,” commented Rolf Bulander, one of Bosch’s top level managers who oversees the company’s mobility activities.
