They are only sensitive enough to detect smoke after a fire has started, which is much too late to stop thermal runaway from igniting an entire bank of batteries. Furthermore, these pre-installed systems cannot be serviced, monitored, or maintained to ensure they are in basic working order due to unit design.
Sandia National Laboratories is working to detect these failures early and provide passengers with adequate warning. While electric vehicles have systems to detect performance issues in lithium-ion batteries, these systems do not address immediate safety concerns. “The nature of battery fires can vary widely, depending on the failure mode.
That’s why the earliest possible detection of a battery failure is crucial to preventing a potential disaster caused by thermal runaway. It is common for mobile BESS units to utilize traditional heat and smoke detectors in interior spaces, but these sensors are not equipped to provide sufficiently early warning of an impending fire.
Current measurements in battery management systems capture temperature and voltage, but these are lagging indicators of safety issues. This means that a warning may not appear until it is too late — specifically when the battery is about to catch fire or is already on fire.
The main reason for lithium-ion battery fires was thermal runaway. If it was not controlled, thermal runaway may cause the battery to rupture and release toxic and highly flammable gases. If these flammable gases are ignited, they might cause a fire or explosion (Yuan et al., 2020).
