Wireless M2M Services to Control Recharging of Electric Cars
By: David Ng |
Ericsson says that it has been working on a Machine-to-Machine service for controlling the recharge cycle for electric road vehicles.
The new architecture allows drivers to control charging of cars while they are plugged into any ordinary power outlet. Additionally, the system directs energy costs to the car owners' bill. 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.
To provide a range of perspectives the concept was developed in a consortium involving Volvo Car Corporation, Göteborg Energi, the leading utility in western Sweden, Ericsson and Viktoria Institute, a non-profit IT research institute.
The Volvo Electric C30, now in low-scale production for leasing customers in Europe, has been used during the project and equipped with the in-vehicle meter and software. Lennart Stegland, Vice President Electric Propulsion Systems, Volvo Car Corporation, said: "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. 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."
Ericsson's contribution to the project is to understand and influence how existing and future mobile networks, services and terminals can support new business concepts as well as services that benefit society. Ericsson is providing IT and communications expertise.
