The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.
Marine class rules: Key design aspects for the fire protection of Li-ion battery spaces. In general, fire detection (smoke/heat) is required, and battery manufacturer requirements are referred to in some of the rules. Of-gas detection is specifically required in most rules.
From a fire protection point of view, these two properties combined have created a whole new challenge: in fire conditions, Li-ion batteries behave in a fundamentally diferent way than batteries with water-based electrolyte. (cathode) and a negative electrode (anode).
For example, an extract of Annex C Fire-Fighting Considerations (Operations) in NFPA 855 states the following in C.5.1 Lithium-Ion (Li-ion) Batteries: Water is considered the preferred agent for suppressing lithium-ion battery fires.
Therefore, PSEMT3 has great potential for practical application in the thermal safety system of battery modules. 4. Conclusion Phase change materials (PCMs) with excellent temperature equalization have attracted great potential to mitigate thermal accumulation, which will benefit to the safety of electric vehicles (EVs) drivers and passengers.
