BOSCH IS WORKING ON EFFICIENT POWERTRAIN SOLUTIONS FOR COMMERCIAL VEHICLES
Bosch states that climate action for road transport calls for a broad technology offensive. According to the German company commercial vehicles have a wide variety of requirements when it comes to powertrain solutions, as the CO₂ emissions differ greatly depending on driving profile, payload, and driving distance. To meet EU requirements, CO₂ emissions need to be cut dramatically in both light commercial vehicles and heavy vehicles by 2030. Bosch is developing a range of efficient powertrains – from combustion engines and battery-electric models to fuel cells.
Bosch offers powertrain solutions for city and long-distance buses as well as for medium- and heavy-duty trucks, and special use cases. An electric motor, inverter, and vehicle control unit are all part of this systems solution. Depending on the topology, the compact electric motor can come as a separate electrical unit in combination with a transmission, or as an active component integrated into a rigid axle. Bosch’s eCityTruck powertrain solutions form a compact module made up of the e-axle, which combines the electric motor, power electronics, and transmission in a compact unit, and an electric drive module (without the transmission). Both solutions are easy to integrate and can be scaled for light commercial vehicles up to 7.5 tons.
eDistanceTruck powertrain solutions:
For long haulage vehicles Bosch is developing eDistanceTruck powertrain solutions. These include the fuel cell as well as hybrid drives. In addition, Bosch is currently examining the technical issues regarding the use of hydrogen in combustion engines and is looking into the marketability of this technology. The engine technologies available today and existing vehicle architectures already form a solid basis for developing this approach.
Together with the startup Powercell Bosch is planning large-scale manufacture of fuel-cell stacks in 2022 and launch the complete fuel-cell system – the Bosch fuel cell power module – in 2023. In addition, Bosch is currently working with other companies as part of the EU-funded H2Haul project to build a small fleet of fuel-cell trucks and put them on the road.
