Battery Management System: From Safe Architecture Definition to System Simulation with Embedded Software

Abstract

Batteries development has changed through the past years with the emergence of electric vehicles. The sustainability of the battery must be ensured along with its safety as they deliver high voltage and the technology used is more difficult to control. Moreover, these batteries may be used in full autonomous vehicles, with no direct human control. In this paper we will show how to set up a complete workflow from the safety requirements down to the software implementation while fulfilling the ISO 26262 objectives. We also show the benefits of using a model-based approach and the gains that can be obtained on some testing or reviews activities. Finally, we complete the flow with the integration within a full-virtual system, which allows for implementing the hardware design, as well as the integration testing.
