Smart Battery Control System based on a Charge-equalization Circuit for an advanced Dual-Cell Battery for Electric Vehicles

Descrizione del progetto


Supplements to strengthen cooperation in ICT R&D in an enlarged European Union

The STREP project "Smart Battery Control System based on a Charge-equalization Circuit for an advanced Dual-Cell Battery for Electric Vehicles" (SuperLIB) addresses the objectives of the call "ICT for fully electric vehicles", targeting the energy storage system. SuperLIB focuses on smart control system solutions for batteries. To enhance the overall performance, the battery consists of high-power and high-energy cells. This combination of two different types of cells together with a smart control strategy and a highly integrated package significantly improves the lifetime, the reliability and the cost/performance ratio of the battery system, by also adding the possibility of fast charging without degrading its lifetime. The control strategy is based on accurate model-based estimators, which are mandatory for precise monitoring of the battery state.The electronic architecture required for the connection of the high-power and high-energy cells enables an efficient management of the current and charge distribution inside the package. The architecture will include electronic circuits for charge equalization and DC-DC converters utilizing advanced techniques of zero-current and zero-voltage switching for higher efficiencies and lower electromagnetic interferences.Safety and control system relevant temperature sensors will be developed for an improved thermal management of the package, thus a potential thermal runaway of a single battery cell can be avoided through early detection of local overheating. In addition this will increase the accuracy of the battery state estimation, which allows the utilization of a wide range of the battery state-of-charge. Thus, the battery can be sized smaller and kept cheaper with still providing the required usable energy content and power performance.
