Energy Storage With Lowered Cost and Improved Safety and Reliability for Electrical Vehicles

ESTRELIA will provide building blocks with enhanced reliability and safety at lowered costs for smart energy storage in FEVs. This is accomplished by a modular approach with ultracapacitor power packs with higher energy density and new BMS ICs. The BMS IC concept will for the first time provide a flexible active cell balancing chip set also suited for the high accuracy required for Li-Ion batteries. This enables higher efficiency by lower energy loss and improved long term reliability at lower electronic component costs for Li-Ion energy packs. New safety gas sensors and flame detection sensors will provide general safety functions for all hazardous events in a FEV. The development of new innovative actuators as low cost power antifuse together with the new energy management HW (BMS IC) and SW will enable dynamic reconfigurable topologies for the energy storage unit, thus still enabling the functionality of the FEV despite single failing cells.
