The “OCC” charging management system supports Austria’s drive to promote electric vehicles by ensuring seamless access to charging stations.

Creating a green future with a charging management system for charging stations dedicated to electric vehicles

Charging stations in Austria are operated through a number of different networks. Until now, these networks have adopted different standards and proprietary systems for usage and billing, which has presented an obstacle to the widespread build-out of charging stations required for promoting electric vehicles and has generated confusion and inconvenience for users. The OCC (Open Charging Station Controller), developed by NTT DATA, provides an infrastructure solution for charging management that interconnects and integrates some of these various systems to enhance user convenience. This platform unifies the charging procedures for electric vehicles and will make charging them at stations as simple as withdrawing money from an ATM.

OCC provides user authentication options such as SMS, QR codes and RFID cards while enabling barrier-free operations across banks and national borders by integrating billing systems. It also allows users to start and stop the charging process, search a map for nearby charging stations and check available connector types through a mobile app on their smartphones, thereby providing necessary information in a convenient way. Benefits for charging station providers include simplified operations such as controlling the supply of electricity, client management, equipment monitoring and accounting while reducing initial costs. For electric power companies, the system features a mechanism for adjusting and managing power distribution and electricity pricing. OCC delivers an infrastructure solution that responds flexibly to every requirement and need that may arise, making it possible to build charging stations safely and at low cost.

Background and Business IssuesBuilding more than 400 dedicated electric vehicle charging stations in the greater Vienna area in 2015

Austria’s Federal Ministry of Life is promoting the use of electric vehicles to mitigate pressure on public transport. The ministry plans to convert 4.5% of all the approximately 200,000 vehicles in the country to electric power by 2020. However, potential owners of these vehicles are concerned about being stranded on the roadside by a battery shortage, representing a major issue hampering the widespread adoption of electric vehicles. Moreover, the few electric vehicles currently registered makes the building and operating of rapid charging stations a relatively expensive and inefficient proposition from an economic perspective, further restricting infrastructure development.

The government’s most recent action has been to formulate a plan to build more than 400 new charging stations for electric vehicles by the end of 2015 within the designated advanced initiative model region of the greater Vienna area. The NTT DATA Group has been involved in electromotive from the very beginning and has been developing advanced platforms through diverse R&D projects in collaboration with electric power companies and charging hardware manufacturers. Under its latest plan, the Group partnered with electric power supplier Wien Energie to construct a system for supplying electricity to charging station operators in addition to this company’s existing providers. This has widened the options for building charging stations.

“We are actively encouraging clean energy,” said Mr. Jürgen Halasz of Wien Energie. ”Citizens of Vienna are very aware of clean energy and are delighted that it’s being used to power electric vehicles. OCC is the most advanced system in Europe, and this solution was made possible precisely because of the innovative applications developed by NTT DATA, our trusted long-time partner. We are currently considering the establishment of a joint financing company with our business partners to address high building costs and contribute to the expansion of OCC.”

OCC is playing a vital role in increasing the number of charging stations and opening the way for realizing the vision of next-generation mobility using clean energy sources.

Implementation Impact and Future ViewsRaising efficiency and expanding the use of clean energy through a charging management system that provides intelligent control

NTT DATA’s charging management system has opened the way to building charging stations regardless of the electricity provider. In 2013, OCC was certified by Hubject GmbH, a joint venture established by six companies in Germany, including vehicle manufacturers and major electric power companies. As a result, “intercharge eRoaming” services that enable users to do charging across national borders and receive or make consolidated bills and payments were added to the system, thus enabling the low-cost construction of simple, user-friendly charging stations. Thanks to OCC, the effective use of clean energy, lower installation costs for charging stations and streamlined operational management have all become a reality.

Moreover, a charging infrastructure that can be easily incorporated into any network can provide solutions for electricity supply conditions not only in Europe, but in other regions across the globe. As a leading company offering cutting-edge solutions, NTT DATA is eager to contribute to the development of social infrastructures that are kinder to the environment.
