It stands to reason that many of the developments in simulation are related to the next generation of vehicles: those that are powered by batteries, and also by hybrid systems. One company making great strides in this area is CD-adapco, which is involved in a collaborative project managed by the Automotive Simulation Center Stuttgart (ASCS). CD-adapco’s STAR-CCM+ is being used as the key CAE tool in the development and validation of simulation models for lithium-ion batteries used in hybrid and electric vehicles. “This jointly funded project makes the very best use of the partners’ skills, and ASCS is the ideal platform to coordinate such forward-thinking technologies,” says Dr Daniela Maionchi, the project manager. The 18-month

Fraunhofer University, helped and supported by Germany’s government, is looking to speed up development of the alternative-powered vehicles, even if they know it could be a long road ahead in terms of educating drivers. Germany’s federal government aims to establish the country as the leading market for electromobility. If all goes according to plan, by 2020 there will be one million passenger cars with an electric drive on German roads. As that date is just over eight years away, a great deal of development work is needed to create a viable product in the relatively short timeframe. Currently few Germans are willing to compromise on range, and the current lack of charging stations and limited battery life are not helping the argument for compact EVs becoming mainstream. The University’s solution lies within the Fraunhofer System Research for Electromobility (FSEM) project, in

Millbrook is a leading transport, development and demonstration facility working at the forefront of the electric and hybrid industry.
Accelerometers with Excellent Thermal Stability
PCB® Series 339A Triaxial ICP® accelerometers are designed with a low temperature coefficient, wide operating temperature range, and good broadband measurement resolution, making them ideal for powertrain development and powertrain NVH applications, or for any vibration measurement requiring tight control of amplitude sensitivity over a wide thermal gradient.

“Having the chance to validate our battery technology in such a rigorous environment has a clear benefit”
project represents an investment of nearly €1 million. It will use technology jointly developed by CD-adapco and Battery Design LLC – through an ongoing collaboration between the two – which will then be deployed by ASCS, and detailed results then compared with a prototype battery pack. Alternative-powered vehicles are quite clearly a major consideration for CD-adapco, and the company believes that the ASCS project will be the first of many for which simulation tools such as STAR-CCM+ will form a prominent part. “We believe the market for such analysis technology exists today and we are investing, both within this project and beyond, into delivering appropriate methods to our users worldwide,” reveals Steve Hartridge, director of electric and hybrid vehicle technologies at CD-adapco. “Having the chance to validate our battery technology in such a rigorous environment has a clear benefit to our users, and is necessary for the successful introduction of any new technology.” Elsewhere in Germany, many other investigations into batteries for electric cars are benefiting from simulation.

The automotive industry is quite rightly perceived as being one of the fastest-moving, technologically aware sectors in the world. Although predictions of flying cars and full autopilot-style systems have yet to become a reality, computers have – and continue to – help rewrite the vehicle development rule book. Fewer physical prototypes, much shorter vehicle and component test programs, and gigabytes of evaluation data transferred anywhere in the world in a matter of minutes: these are just some of the benefits being realized by OEMs as they strive to achieve a more efficient vehicle creation process. The industry seems to be in agreement that many further developments are expected to help out even further in the future.
