Reliable Determination of Electric Vehicle Driving Ranges - A Novel Approach Based on Car-2-Infrastructure

摘要

Due to specific boundaries of available electric vehicles, like limited driving range, long battery charging time and high battery costs, alternative approaches for enabling this technology have to be considered. While the mentioned drawbacks are limiting the use-cases for this technology, they are also responsible for its predominant use in the short way transportation domain. Generally, this is considered as unacceptable disadvantage. To limit the aspect of "costs", the example of the "Aachener-Baukastenprinzip" ("Konzept Zeitgeist") used by the StreetScooter AG can be followed - customer specific requirements are realized in the amount of a fleet with modular, exchangeable components. Based on this technique, a platform is realized for producing competitive, custom-made vehicles and to allow new aspects in designing system architecture. This concept shall be deployed to the information and communication technology in electric vehicles as part of the publicly funded project O(SC)~2AR (Open Service Cloud for the Smart Car). O(SC)~2AR itself is part of the BMWi funded research topic "IKT fur Elektromobilitat II", responsible for researching upcoming requirements of a new Information and Communication Technology (IKT)-architecture in electromobility. Furthermore, "IKT fur Elektromobilitat II" focusses on "Smart Grid" and "Smart Traffic", where new approaches should combine the needs of energy provider and electromobility into one system, as shown in figure 1. Better connected partners will be able to provide new services, which will lead to a higher amount of communication. Besides the communication with the user via Human Machine Interface, a communication by information channels to a data processing infrastructure must be realized. In order to accomplish all these customer and vehicle specific interfaces and requirements, the ruling communication infrastructure, based on proprietary, non-open systems, must be redesigned fundamentally.
