Lithium-ion batteries are increasingly being used in safety-critical applications, such as automotive, avionics and aerospace systems. They require the adoption of an electronic control system, called Battery Management System (BMS), to guarantee their safe and effective operation. Therefore, the reliability of the BMS is of paramount importance. In this paper, we analyze the effects of Single Event Upsets (SEUs) occurring in the control logic of an important BMS subsystem, i.e., the charge equalizer.

Abstract

Lithium-ion batteries are increasingly being used in safety-critical applications, such as automotive, avionics and aerospace systems. They require the adoption of an electronic control system, called Battery Management System (BMS), to guarantee their safe and effective operation. Therefore, the reliability of the BMS is of paramount importance. In this paper, we analyze the effects of Single Event Upsets (SEUs) occurring in the control logic of an important BMS subsystem, i.e., the charge equalizer. Moreover, some SEU mitigation techniques based on logic redundancy are presented and their effectiveness is compared through fault simulation.
