International Journal of Automotive Engineering
Preserved Fulltext
Initiation methods for thermal propagation tests are being discussed in the EVS-GTR. In this paper, laser irradiation was compared with nail penetration and heater heating using a prismatic Li-ion battery module from the viewpoint of heat energy transfer to adjacent cells. Such transfer with laser irradiation was 0.025% of that of heater heating and the adjacent cell's temperature rise was less than 1°C by thermal runaway of the target cell. This result demonstrates that laser irradiation is a
