Abstract:

The thermal power of a thermal runaway cell is calculated using its temperature obtained by existing ARC tests. The power is assigned to cells in a hybrid locomotive traction battery system, and the transient temperature of other cells around it is simulated. The simulation shows that one cell's thermal runaway cannot incur propagation when it is cooled by an air-conditioner. However, it will lead to propagation without an air-conditioner in modules, and the parallel cells' thermal runaway will cause propagation in the upper package. Lastly, preventing thermal runaway propagation was studied.

Key words: hybrid locomotive, lithium-ion traction battery system, thermal power, thermal runaway propagation
