Automotive
Digitalization represents the ultimate challenge for the automotive industry, as it brings fundamental changes to the way cars are developed, produced, sold and used. This change not only affects the technologies used, from the drive to the E/E architecture, but also all value creation processes along the entire life cycle of a car.
Digitalization of vehicles
On the one hand, the increasing networking and digitalization of vehicles requires a high level of competence in the field of information technology. New technologies such as artificial intelligence, big data and cloud computing must be mastered and integrated into production and development. At the same time, vehicles must be protected against cyber attacks.
New trends in the automotive industry
On the other hand, digitalization is also changing the way vehicles are used in general.
Car sharing, autonomous driving and the development of new mobility services require a rethink and a reorientation of the established companies. In addition, new players are entering the market, such as start-ups and technology companies, which challenge the established companies with innovative concepts and business models.

Selected reference project in the automotive sector
Client: Bertrandt Ingenieurbüro GmbH, Auftragsart: Werkvertrag
Context and objective: With regard to a smoothing of harmonics (ripple) in AC charging operation, the charging electronics of an on-board charger are to be optimised in order to be able to achieve a significant improvement in the life expectancy of the battery.
For this purpose, an additional compensation circuit is to be added to the existing topology. Parallel to minimising ripple, a significant reduction in the volume of the charger and an increase in power density are to be achieved. A HW prototype is to be built and the results validated with it.
Implementation
- Topology investigation and optimisation, modelling and simulation
- Creation of a layout for the simulated topology and hardware prototyping
- Testing of the prototype by means of low-voltage measurements
- Hardware optimisation with a view to increasing power density
Results: HW prototype, which demonstrates an AC rib compensation of approx.87% as well as a volume minimisation of the component by approx. 30%.
