Electric Vehicle Intelligent InfraStructure (ELVIIS)

Will Sweden be the first country to implement a user-friendly system for charging electric vehicles? The challenge concerns stakeholders from multiple industrial segments. Together with partners in the automotive, energy and telecommunication sectors, Viktoria has initiated and facilitated the research project ELVIIS – Electric Vehicle Intelligent InfraStructure – that uses the existing infrastructure to charge vehicle batteries.

Car manufacturers have been developing electric vehicles (EV) for quite a while and today almost all the major players have already released, or will release, their EV models. The performance of the EV’s is competitive in terms of acceleration and comfort, but a major disadvantage is still the modest driving distances that can be covered by the batteries. Other essential factors limiting the EV market penetration is the lack of infrastructure for convenient charging of the batteries, and the option of receiving the bill from a public power outlet or from a friend’s house. To deal with the situation, Viktoria Institute invited Volvo Cars, Ericsson and energy company Göteborg Energi to the research project ELVIIS, Electric Vehicle Intelligent InfraStructure.

Our goal was to provide a user-friendly solution responsive to changing electricity prices, and cost-efficient to implement,” says Stefan Pettersson, Research Manager at Viktoria.

Intelligent charging when power is less expensive

The solution uses the mobile telecom network to coordinate the charging of cars, which increases the efficiency of the grid. The driver decides how and when to charge the car. The information is sent over the mobile network to a system that determines the best time for charging, based on the lowest cost and current demand on the grid. After that, the driver’s bill is charged, no matter which power outlet is used. At present, the driver needs to enter a specific power outlet ID, but eventually, it will be possible to use the car’s satellite navigation device to identify nearby outlets.

The solution is based on systematic user studies, extensive interviews with drivers, and workshops. “The big challenge was to understand how business models from other industry segments work, and to merge different perspectives into one solution. In the next step, we want to involve a larger group of energy companies in Sweden or at the Nordic level to work with standardization issues,” says Stefan Pettersson.
