Abstract

This study defines a process to devise random power spectral density (PSD) profiles that are representative of 100,000 miles of UK customer electric vehicle (EV) usage utilising vibration measurements from three contemporary EV’s, for undertaking vibration durability evaluations of underfloor mounted rechargeable energy storage systems (RESS). This paper also presents a critical assessment of current random vibration test procedures available to engineers for validating the mechanical performance of EV RESS via comparing the shock response spectrum (SRS) and fatigue damage spectrum (FDS) of these standards to the SRS and FDS of 100,000 miles UK durability.
