In general, the EIS method has apparent positive significance for real-time safety monitoring of LIBs and other batteries. The real and imaginary parts of the impedance can separately establish functional relationships with temperature and be used to accurately monitor the working state of the battery.
Remedial measures include controlling the charging rate, performing battery equalization, regular inspection and maintenance and controlling the depth of discharge to effectively manage the charging and discharging state of the battery system.
Before TR occurs, cooling media, such as liquid nitrogen (LN) (Fig. 18) and the refrigerant R410A , can be sprayed directly on the surface of the battery pack to prevent the occurrence and propagation of TR; this prevents TR in the early stage of LIB fires by rapid cooling through coolant vaporization.
