Study of lithium-ion battery ageing cycled with current profiles from railway applications

Lithium-ion batteries have been attracting significant attention in transport industry and particularly in hybrid railway transport applications. Despite significant progress, their lifespan is still limited. The knowledge of the operations leading to severe degradation is, therefore, crucial to optimize their use. From this perspective, experimental tests were conducted on lithium-ion battery cells. Two cells were cycled with two different real duty cycles from railway applications. This study aims at comparing the impact generated by the two profiles on the cell capacity, internal resistance and open-circuit voltage.
