In the next ten years, mobility will change fundamentally. There are more uncertainties in automotive markets than ever before. What road is powertrain electrification taking – and how fast is it progressing?
The challenges facing suppliers and OEMs are huge. They need to strike the right balance between customer expectations, technical possibilities and legal regulations, act with foresight, and send new impulses to the market.
CTI SYMPOSIUM Berlin looks to the future
The programme of CTI SYMPOSIUM Germany will reflect these general changes. Along with the latest technical innovations, strategic considerations will also play an important role in the presentations. Forecasts, compiled with the aid of statistics and market analysis, are indispensable planning tools. Using modular, scalable concepts, stakeholders can respond flexibly to market demands – and absorb the considerable costs of electrification.
Market analyses create transparency and identify trends
What would the automotive market be without statistics and forecasts? From managers and journalists to auto fans, everyone looks forward to the latest sales figures. Which models top the charts? What are competitors succeeding with? The figures provide the answers to all this and more. At CTI SYMPOSIUM Berlin, two speakers will be taking a close look at market developments in the specific field of e-mobility.
Johannes Flemming (P 3 automotive, Deutschland) will begin with a general overview of EV sales figures in 2019, then zoom in on the compact, affordable segment. Unlike expensive premium BEVs (Tesla, Jaguar, Audi, etc.), this segment targets the important mass market. After analyzing the various electrical powertrain architectures and selecting the best implementation, we can find answers to a key question: “Which electric cars fascinate and convince customers most?”
Claudio Vittori (IHS Markit, Italy) will analyze how increasingly-integrated EV powertrains affect supply chains, based on findings from in-depth research by IHS Markit. To better understand market demand for key electric drive components and technologies, the company has developed and applied innovative forecasting methods. The survey examines capacities at various stages along the supply chain. It also explores existing and future approaches to powertrain integration, particularly the integration of e-motors and power electronics. Thermal management is also becoming more important. IHS Markit’s research identifies new thermal components that are needed for optimal driveline performance. In BEVs, thermal management is also important for heating the cabin comfortably without sacrificing too much range. In his presentation, Claudio Vittori will consider the key features of electric automobiles and customer requirements, and examine their influence on OEMs and suppliers in various major automotive markets.
Roadmaps for tomorrow’s electrified drives
Developers of next-generation electrified powertrains face a very special conflict of interests. In addition to meeting global CO2 legislation, they must also offer mobility in ways that synch with consumers’ needs.
Dr Christoph Danzer (IAV, Germany) will present a new, holistic development approach that focuses on user behaviour patterns when identifying future mobility scenarios. Based on specific mobility scenarios, this approach can systematically generate large numbers of DHT and E-Axle platform systems, optimize them in terms of CO2 balance (tank-to-wheel and well-to-wheel), production costs and driving performance, then compare them. The approach also optimizes systems at fleet level. The aims are to create platform systems with a minimum of carry-over parts, and to reduce costs overall.
Navigating the wide range of options, hybrid modes and architectures for powertrain hybridization is getting harder all the time. To shed more light on the topic, Fabian Holldorf (Hofer f & e, Germany) will present the findings from an internal study on hybrid powertrain technology. He will identify highly promising hybrid powertrain architectures, and evaluate their electrical and mechanical build. Using this study, developers can identify each hybrid architecture’s potential and analyze how it affects factors such as performance, comfort, fuel efficiency and compliance with specific local regulatory requirements. The survey also takes varying requirements for different vehicle classes into account.
Hybridization – the easier the better
For HEVs and PHVs to prevail on a broad basis across all vehicle classes, affordability is key. Dierck Reitz (Schaeffler, Germany) explains in a nutshell how this affects hybrid drive development: “Since electrical components cost more, you have to simplify the technical design wherever possible.” The speaker will present a new concept that Schaeffler has co-developed with a global OEM. This P2 system features a DHT (Dedicated Hybrid Transmission) and two electric motors, and is said to make the whole powertrain highly efficient in both pure electric and hybrid modes. Two coaxial wave winding electric motors are designed for a similar layout, and can be combined as a modular system via an integrated double inverter. For still more continuous power, both are configured for oil cooling. To make the concept affordable, standardized and modular, the Schaeffler Dedicated Hybrid Multi Drive (DH-MD) will launch as a highly integrated system. It offers high quality hybridization for ultra-compact transmissions based on CVTs, DCTs and AMTs. Particularly in CVTs, it can be combined with a fully integrated torque converter to set a new benchmark for powertrain length.
Dr Carsten Bünder (Magna Powertrain, Germany) will present a new transmission development for high-volume applications in the vehicle segment up to 300 Nm. Globally, this is by far the biggest market segment; it is particularly price sensitive, and highly dependent on economies of scale. Hence, Magna’s new modular hybrid transmission family is based on a four-speed DCT. In highly electrified drives, the electric motor handles driveaway, low-speed driving and reverse gear. Since this requires no more than four ratios, the mechanical complexity can be reduced in multiple ways. The transmission family covers a wide range of customer requirements, yet still offers the robustness of a proven architecture. Every innovation at ‘building block’ level directly benefits the whole product line, and the same building blocks can be used to scale the properties and characteristics of each variant. This approach involves no functional compromises (e.g. in drivability or shift quality), yet enables significant cost savings from simplifying mechanical aspects as electrification levels increase. In his presentation, Dr Carsten Bünder will explain the full bandwidth of configurations and potential applications. He will show which transmission building blocks are most important for ensuring functional scalability while maintaining the basic architecture. The technology is an extension of an existing product strategy, and is ready for series production.
CTI SYMPOSIUM Germany – inspiring discussions
Once again, this year’s CTI SYMPOSIUM Germany promises to be a fascinating event – and an important forum for manufacturers and suppliers. On stage in the plenary and in sixteen sessions, participants will be able to experience the latest technical developments and discuss the burning issues surrounding automotive powertrains.
In the eagerly awaited podium discussion in the plenary, top-notch experts will debate
a very important topic: “Will regulations allow technology to match customer expectations?” Two podium lectures are also sure to spark lively dialogue. The up-to-the-minute theme of Hakan Yilmaz (BorgWarner, USA) is: “Path to plug-in e-propulsion with balanced and sustainable products”. Stephan Rebhan (Vitesco Technologies, Continental, Germany) will present further fascinating insights under the title: “Automotive industry undergoes the most significant change ever – impacts on powertrains and vehicle design”.
Beyond that, lively and inspiring dialogue will permeate every aspect of the symposium – from the extensive CTI SYMPOSIUM EXPO and the CTI Award for young drivetrain experts to the CTI TEST DRIVE … and above all, the relaxed setting of our CTI NETWORKING NIGHT.
