Smarter Control of Electric Vehicle Batteries
In ScienceDaily, January 13 2010
Electric vehicles are fitted with one or several electric motors driven by energy stored in large batteries that may consist of thousands of small cells. These high-capacity batteries give current models of electric cars a range of up to 200 kilometres.
The EU's E3Car project is studying how to utilise battery power as efficiently as possible in such vehicles. SINTEF is one of 33 participants in the project, which comprise vehicle manufacturers, automotive industry suppliers and research centres from all over Europe.
The project has taken up challenges on several fronts. Battery efficiency, higher energy density and power and energy control make up one group of topics. The infrastructure required for rapid charging or systematic change of battery is another. And smart dynamic sensor-based monitoring, where nanoelectronics can provide real-time control, is a third field of research.
