Faster charging, longer stability of performance not only for electric vehicles but also for smartphones and other battery powered products – that’s what the recently started “Spartacus” research project wants to achieve. By utilizing advanced sensors and cell management systems, “Spartacus” aims to reduce charging times by up to 20 % without compromising the reliability and service life of batteries. The European Union is funding “Spartacus” as part of the Battery 2030+ research initiative.

SPARTACUS, the acronym stands for "Spatially resolved acoustic, mechanical and ultrasonic sensing for smart batteries". The SPARTACUS project aims to develop a multifunctional sensor array technology for various types of batteries combined with an advanced battery management system ensuring improved charging behaviour and maximized battery lifetime. The optimized detection of battery health and battery function will make it possible to recharge in a safe but fast way – much faster than before. The project will focus on mechanical and acoustic sensors complemented by temperature sensors and electrochemical impedance spectroscopy. The sensor data will feed an advanced battery management system, which compares real data with battery data models to gain a comprehensive analysis of the real battery condition.
