SuperLib Project: Advanced Dual-Cell Battery Concept for Battery Electric Vehicles

This paper describes the Advanced Dual-Cell Battery Concept for Battery Electric Vehicles in the framework of the European Seventh Framework Programme (FP7). The project investigates a well promising new energy concept, whereby high energy and high power dimensioned batteries are combined on cell level. The proposed methodology should allow to extend the battery life cycle by imposing peak power at the high power cell and supplying energy by the main energy source: high energy cells. Moreover, the new concept will assist to prolong the range of an e-car compared to conventional battery electric vehicles with high energy cells. Therefore, new advanced battery models, including adequate estimation techniques for battery model parameters, state of charge and state of health, will be developed at the Vrije Universiteit Brussel and IFP Energies Nouvelles. Then, from the point of view of the electronic architecture, the energy transfer between high energy and high power cells and balancing system from the other side will be carried out by Valeo and IFP Energies Nouvelles. Finally, this innovative concept will be validated by VDL, Volvo, CRF, European Batteries, and BOSCH companies.
