This paper presents a comparison on cycling strategies conducted on an experimental study on an NMC lithium-ion battery. The investigation focused on examining the capacity degradation on batteries subjected to two cycling protocols, conducted at an ambient temperature of 0 °C and stress factors that depend on actual capacity instead of nominal capacity. The capacity losses were evaluated post-cycling, revealing a degradation of 28.63 % and 25.5 % for cells subjected to Protocol 1, whereas cells cycled under Protocol 2 exhibited lower capacity losses of 21.58 % and 20.73 %.This paper also presents the impact of the discharging current and the depth of discharge on capacity utilization to support the development of optimized cycling protocols for practical applications.< Réduire
