IBM and EKZ partner to make plug-in charging more convenient with new smartphone application
17 October 2011
IBM Research has teamed with EKZ, the electricity utility provider of the Canton of Zurich in Switzerland, on a new pilot project that will allow consumers conveniently to charge electric vehicles and monitor their energy costs, using mobile devices. This near real-time information will also help utility providers better manage power grid loads during peak charging times.
The pilot combines a Web-based application designed and developed by IBM scientists in Zurich and a data recording device created by the Zurich University of Applied Sciences (ZHAW). The device, roughly the size of a phonebook, was installed in several electric vehicles, including a Renault Twingo to collect information on the vehicle’s battery charge level, location and the power source. The device transmits the data via a cellular network to an IBM cloud based on IBM BladeCenters running DB2 and WebSphere. This monitoring capability not only benefits the user but also provides utility providers with further insight into energy generation and consumption.
The project has the potential to contribute to Switzerland’s energy policy goal of increasing the proportion of electricity produced from renewable energy by 5,400 gigawatt hours (GWh), or 10% of the country’s present-day electricity consumption, by 2030. According to the latest statistics available, approximately 55.6% of Switzerland’s overall electricity production comes from renewable sources, with hydropower by far the biggest contributor at more than 96%.
Electric vehicles can be used to buffer the irregular production of electricity from future renewable sources, which will contribute to the overall stability of the electrical network. "With this project we can show how electric vehicles can create a balance between supply and demand for smarter energy grids.—Franken, head of the Energy Distribution department of EKZ and executive management member
The IBM app runs on most smartphones, tablets and Web browsers, and provides an integration point between the vehicle, the utility provider and the driver. Using a simple four-button interface, the app shows the vehicle’s battery level, range of travel distance, vehicle location, charge schedule and current energy costs in real time.
This service will make electric vehicles more attractive to consumers by taking into consideration their preferences, while still factoring in cost and overall convenience. In this pilot, the real-time analysis of supply and demand together with a control algorithm will create a dynamic incentive for a sustainable way to charge an electric vehicle’s battery, putting us another step closer to establishing a cleaner transport system.—Dieter Gantenbein, leader of the Smart Grid research project at IBM Research – Zurich
Whether at home, in the office or thousands of miles away, electric vehicle owners can quickly consult their mobile device to check whether their car’s battery level is sufficient for its next use. Another advantage of the app is that it can be programmed to start battery charging at a future point in time, for example when rates are lowest or when a trip is planned.
The IBM app also allows vehicle owners to delegate the responsibility of recharging the battery to the utility provider, which can schedule charges based on the availability of renewable resources, such as sun and wind, allowing the utility to improve load balancing and prevent outages. EKZ believes this will be a value added service that will gain more significance as electric vehicles become prevalent.
To analyze the programmed charging process of electric vehicles with renewable energy, the pilot project takes real-time production data from photovoltaic solar panels located at EKZ’s facility in Dietikon, which then gets transmitted to the cloud service. In this charge mode, the electric vehicle is charged when solar electricity is being produced. If less solar energy is being generated, the charging process can adapt automatically.
EKZ provides roughly 10% of all electricity consumed in Switzerland, making it one of the leading Swiss utility providers.
"With this project we can show how electric vehicles can create a balance between supply and demand for smarter energy grids."
Except energy grids are going to be downsizing. We are going to change the entire energy paradigm by removing unsightly grid components, power poles, transmission towers, 600,000 miles of dysfunctional cable, transformers, breakers, fuses, insulators, coal burning plants, turbines, dams, river redirection, etc.
The grid will remain to service large industry and the few consumers who don't want to generate their own low cost power and heating. It may be useful for buffering wind and solar farms IF their costs can compete with electric energy available at $0.002/kWh or less.
But it is good to see IBM participating in the electrification of transport. How about converting their worldwide fleet of vehicles to PHEV?? SOC battery data is already heavily monitored by EV makers - it's unlikely that third parties can bring anything new to the game.

And now the announcement to Wall Street:

A Forbes blog site. Nothing endorsed by the magazine, let alone real scientists or money people. And Gibbs himself hedges with "If this device works as claimed...."
Yawn. Wake me up when it doesn't look like a replay of the cow magnets scam, okay?
