24.2.2012 Volvo trials mobile EV charging scheme
A new electric vehicle charging system, called ELVIIS, could mean that soon electric vehicle owners will be able to charge their vehicles up from anywhere, and see the cost appear on their own electricity bill.
The ELVIIS (Electric Vehicle Intelligent Infra Structure) consortium is a collaboration between Volvo Cars, Goteborg Energi, Viktoria Institute and mobile provider Ericsson. Although not yet commercially available, the general idea is to remove barriers for electric vehicles in day to day life.
The main smart innovation linked to this concept is in using GPS to identify at which charging point the car is parked. The driver is then able to pre-set timing and charging amount on a touch screen in the vehicle or remotely using a smart phone.
The car then communicates with the grid via a mobile network, and sets the charging scheme in order to support optimal utilisation of the grid and most favourable electricity price. The driver will be informed of any unintended interruption to the charging process via their mobile phone.
This system is then able to calculate and direct the cost of the electricity used to the car owner's personal utility bill, eliminating the charging problems associated with roaming between electric vehicle charging point networks across the county.
The Volvo C30 Electric has been used as a test car in the project. Equipped with an integrated 7-inch colour touch screen, it makes the smooth charging concept available at the driver's fingertip. Five C30 Electric cars will now be used for testing and evaluating the technology during a year.
"Our basic view is that the owner of an electric vehicle shouldn't have to sacrifice any of the properties he or she expects from a luxury car," says Lennart Stegland, Vice President Electric Propulsion Systems, Volvo Car Corporation. "This smart technology for charging in any outlet, and paying automatically via your own electricity bill, is an excellent example of how we do everything to make the daily use easier for the customer."
The concept is developed on a generic communication platform to make the technology globally applicable. The ELVIIS technology is fully in line with Volvo Car Corporation's development of Sensus technology, which in an interface that allows detailed communication between the car and the driver's digital mobile devices.
Volvo has confirmed that they will roll out around a batch of C30 Electric models for more thorough testing of the car itself; they will also be monitoring user’s charging habits.
