High voltage battery system and method for isolating faulty battery module

Abstract

A battery system for an electrified vehicle includes a battery pack, a fastening assembly, a decoupler, at least one sensor assembly and a controller. The battery pack includes a battery module assembly having at least a first battery module and a second battery module. The fastening assembly includes a fastening set associated with each battery module. The decoupler is configured to initiate decoupling of a selected battery module from the battery pack. The sensor senses a thermal event at a faulty battery module and communicates a thermal event signal in response to the sensing. The controller receives the thermal event signal and, responsive to the thermal event signal, communicates a decoupling signal to the decoupler to decouple the faulty battery module from the battery pack.
