Embedding Electrochemical Impedance Spectroscopy in Smart Battery Management Systems Using Multicore Technology

Abstract

Improving the range of electric vehicles is a key requirement to achieve market acceptance—one important aspect is the efficient management of the electric energy stored into the cells. Within the INCOBAT (INnovative COst efficient management system for next generation high voltage BATteries, http://www.incobat-project.eu/. The research leading to these results has received funding from the European Union’s Seventh Framework Programme (FP7/2007–2013) under grant agreement no. 608988.) project, we propose innovative and cost efficient battery management systems for next generation high voltage batteries targeting a more accurate estimation of the battery state over the lifetime. Target of this paper is to present the project’s achievements with respect to (a) deployment of safe and secure multicore computing platforms, (b) embedding of electrochemical impedance spectroscopy algorithms, (c) combined thermo-mechanical robustness tests, and finally (d) outlook towards integration of INCOBAT technology into a vehicle demonstrator.
