RISE ICT stories: Smart charging of electric vehicles


A new architecture, developed by RISE Viktoria, Ericsson, Volvo Car Corporation and Göteborg Energi, allows drivers to control charging of their electric cars while they are plugged into any ordinary power outlet. Additionally, the system directs energy costs to the car owners’ bill.

Smart charging

The driver sets the time and amount to charge on a console in the car or remotely via a smartphone or tablet. Using the mobile network, the car then communicates with the grid so that charging is scheduled based on energy prices on the grid, reducing user costs. For the energy utilities, coordinating the charging of cars across the grid is more efficient and sustainable.

Successful cross-industry collaboration

The project concept, of using intelligent infrastructure for controlling the charging of electric vehicles, was first initiated by Viktoria Institute in November 2008 in a meeting with Göteborg Energi. The idea was suggested to Ericsson and Volvo Cars some months later. The first meeting with all partners was held in April 2009 where the project idea was further developed. The pre study project was initially funded by the partners followed by funding by Region Västra Götaland and Göteborg Energi Research Foundation.

Three years later, in February 2012, the ELVIIS-concept was introduced to the public by the partners both in Göteborg and by Ericsson at the Mobile world congress in Barcelona. The concept, and especially the cross-industry collaboration has been noted in the international press with more than 200 articles around the globe.

In his keynote speech at the Mobile world congress in Barcelona, Hans Vestberg, CEO of Ericsson presented the concept and stated that “These are examples of how our industry together with vendors, operators and other industries can create efficiency”.
