The project aimed to determine the performance characteristics and life-time of a range of currently available and futuristic traction battery systems, using a common European qualification procedure. The economic, environmental, manufacturing and supply aspects of each battery system would also be considered, to give a clearer picture of the business-related aspects of the technology. The overall objective was to identify and provide guidance on the most suitable traction batteries for electric and hybrid vehicle applica-tions.
One of the main reasons why electric vehicles have not yet been commercialised is the difficulty in developing traction batteries suitable for operation in cars. Although various battery systems have been developed to such a level where production seems possible, there is still much research that needs to be undertaken. This project was a co-operative effort between nine European car manufacturers (all members of the EUCAR organisation) and six independent test institutes, located in Germany, Italy and Sweden, who test traction batteries under conditions dictated by actual vehicle usage.
