The primary degradation mechanisms inducing battery aging include: (i) loss of recyclable lithium; (ii) loss of active materials; and (iii) impedance growth [39]. In this work, an ANR26650 LiFePO4 battery pack, comprising cylindrical cells manufactured by A123 systems, is considered. It has been proven that the SEI growth is the dominant aging mechanism for this battery, and a key manifestation of its aging is capacity loss [40], [41], as indicated by Qtot=Qcyc+Qcalwhere Qcyc represents the

Plug-in hybrid electric buses with large battery packs exhibit salient advantages in increasing fuel economy and reducing toxic emissions. However, they may be subject to expensive battery replacement caused by battery aging. This paper designs an online, coordinated optimization approach, based on Pontryagin's minimum principle, for a single-shaft parallel plug-in hybrid electric bus, aiming at minimizing the total cost of energy consumption and battery degradation. Specifically, three key contributions are delivered to complement the relevant...
