Battery packs are charged and discharged as a single battery, therefore it is possible that differences between cells (i.e. chemical characteristics, operating temperature or different internal resistance) can cause differences in cell remaining capacity, leading to overcharging or overdischarging of respectively most charged and most discharged cells,(More)
Lithium-ion batteries are the core of new plug-in hybrid-electrical vehicles (PHEV) as well as considered in many 2nd generation hybrid electric vehicles (HEV). In most cases the lithium-ion battery performances play an important role in the vehicle energy management. As consequence, battery modeling is one of the most important tasks for hybrid and(More)
In this work an experimental parameter identification and validation for an electrochemical lithium-ion battery model is illustrated. The model was presented in [2] where, aimed at estimating the battery State Of Charge (SOC), the model was also averaged and an extended Kalman filter based on the average model was designed. The identification procedure is(More)
In this paper an averaged electrochemical lithiumion battery model, presented and discussed in [2] and [3], is identified and validated through experimental data by a 10 Ah li-ion battery pack, during charge and discharge experiments. The model is based on an approximation relationship between the averaged Butler-Volmer current and the average solid(More)
