Electromobility for passenger cars

Power on! Electric cars off to a flying start

The electric drive is increasingly becoming a key component of personal mobility. Particularly in cities, hybrid and electric cars can display their strengths, which include fewer local emissions and a quiet, yet fascinatingly dynamic propulsive power. These characteristics make vehicles with an electric powertrain more environmentally friendly and convenient – with built-in driving enjoyment.

With powertrain technology from Bosch, electromobility not only becomes the means of choice in individual traffic but it is also increasingly more attractive for the mass market and more economically viable for manufacturers. The purely electric range of vehicles is increasing while emissions continue to decline. This is made possible by innovative technology from Bosch such as the eAxle and the fuel cell-electric drive.

The Bosch portfolio not only includes highly efficient and compact components, but also complete solutions whose easy integration in the vehicle permits swift market maturity. Beyond the powertrain, Bosch is also optimizing energy flows throughout the entire vehicle with smart thermal management, for example, for particularly efficient air conditioning.

With manufacturing and development sites worldwide, Bosch is strongly committed to electric mobility and familiar with the local particularities and demands of individual markets. For example, Bosch serves China as an important lead market for electromobility with suitable solutions and even manufactures the eAxle and 48-volt battery there.

Fuel cell-electric drive

Bosch is developing the fuel cell-electric drive to production maturity.

Bosch is developing the fuel cell-electric drive to production maturity.

High ranges and short refueling times: Vehicles with a fuel cell-electric powertrain can drive several hundred kilometers on a single tank – and entirely without local CO2 emissions, just like battery-electric vehicles. The electric energy for the powertrain is generated from hydrogen by the fuel cell directly on board the vehicle. The hydrogen is fueled as a highly-compressed gas. Similar to conventional fuels, this process only takes a few minutes.

Bosch has already achieved great progress in the development of fuel cell-electric drives for heavy-duty commercial vehicles and will also be increasingly deploying this technology in passenger cars in the future. As a system supplier, Bosch already avails of extensive expertise in the area of fuel cell technology and offers a comprehensive portfolio of easily integrable components and fuel cell solutions for trucks and cars.

How the eAxle from Bosch works

Iincreasing range and reducing costs: The eAxle from Bosch grants manufacturers swift access to electromobility: with the electric axle drive, efficiency, low development costs and short times to market become reality. The eAxle unites the electric motor, power electronics and transmission in one, representing an all-in-one principle for manufacturers. This creates synergies which reduce costs, save time and therefore improve efficiency. With its great scalability, the eAxle can also be used variably and straightforwardly for various vehicle segments. This makes it a perfect start-up drive for electric cars – and this holds for established manufacturers, too. Specially for the Asian market, Bosch is commencing volume production of the eAxle in the Chinese city of Taicang in 2019.

Hybrid systems

Hybrid systems reduce fuel consumption and emissions.

Hybrid systems reduce fuel consumption and emissions.

With low-voltage and high-voltage hybrid systems, Bosch combines the benefits of efficient combustion engines and resource-saving electric powertrain systems. Particularly in combination with regenerative braking systems, hybrid systems allow reductions in both fuel consumption and emissions. With plug-in hybrid vehicles, the range of the electric powertrain components usually suffices for inner-city driving with the combustion engine providing supplementary power on longer journeys.

Bosch develops a Rolling Chassis platform together with Benteler

Rolling chassis plattform

Modular and scalable integration solutions for electric vehicles: Electrical powertrains, steering systems, brakes – Bosch has all the building blocks of electromobility in its portfolio. As part of the development alliance with the chassis and automotive technology expert Benteler, the company is demonstrating how all Bosch products for electric vehicles can be integrated with one another and which innovative cross-domain functionalities, such as functions involving the steering and braking systems can be realized. Benteler takes responsibility for the mechanical integration. This means the integration of components and subsystems as well as the battery system into a so called Rolling Chassis, a ready-to-drive modular platform that provides a highly versatile basis for many different vehicle types. This approach enables carmakers to implement new vehicle concepts much more quickly than before and helps to further optimize their in-house engineering efficiency.
