Abstract Batteries (mostly Li-ion) for electric and hybrid vehicles are integrated in a metal structure (battery compartment) associated with the chassis. A dedicated electronic (called BMS, Battery Management System), controls and balances the voltage between the different elements of the battery. However it appears this monitoring does not cover all the failures mode of the battery or at least it is possible to better anticipate their occurrence. Glycol water mixture coming from the cooling system, abnormal concentration of methane, overheating, shocks the battery compartment would have absorbed and presence of smokes are all relevant of a battery failure. As a supplier of metal envelops for the battery, DURA has developed a complete system to detect those threats, in particular the liquid and the smoke detection systems. The set of sensors is placed in the battery compartment, while the ECU which manages them and integrates the various strategies and also communicates the resulting information to the vehicle is located outside this compartment.
