The global objective of the Spartacus project is to develop an affordable sensor solution to detect degradation and failure mechanisms, intentionally before a loss of performance. The project will focus on mechanical and acoustic sensors completed by electrochemical impedance measurement and temperature sensors. The sensoric data will be correlated to battery performance and to corresponding models. The state of different parameters (SoX) will be monitored continuously which enables the management system to cycle the battery on an age-dependent optimum level. An advanced Battery Management System (BMS) will be developed. BMS will work in proximity to the cells terminals (i.e. a cell management system, CMS) to efficiently exploit all the sensoric data without extra-wiring harness. At the end of the project, an 24V smart battery module will be assembled and the CMS enhanced by the sensoric data will be validated in different ageing conditions or for misused or abused batteries at lab-scale (TRL4). Quantitatively, a reduction of 20% charging time without any negative effect on life time by exploitation of sensoric data is targeted. By usage of sensoric data, cell monitoring will be also improved and will increase the safety of batteries and avoid overheating (thermal runaway), fire or explosion.


The global objective of the SPARTACUS project is to allow for fast charging of battery modules without any substantial negative impact on lifetime / cycle life by the implementation of an array of mechanical, acoustic, thermal and advanced impedance sensors integrated on individual cells.
