Development and validation of a battery model useful for discharging and charging power control and lifetime estimation / Agarwal, V. in IEEE transactions on energy conversion, Vol. 25, N° 3 (Septembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 3 (Septembre 2010) . - pp. 821 - 835 Titre : Development and validation of a battery model useful for discharging and charging power control and lifetime estimation Type de document : texte imprimé Auteurs : Agarwal, V., Auteur ; Uthaichana, K., Auteur ; DeCarlo, R. A., Auteur Année de publication : 2011 Article en page(s) : pp. 821 - 835 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Battery  management  systems;  battery  powered  vehicles;  lead  acid  batteries Résumé : Accurate information on battery state-of-charge, expected battery lifetime, and expected battery cycle life is essential for many practical applications. In this paper, we develop a nonchemically based partially linearized (in battery power) input-output battery model, initially developed for lead-acid batteries in a hybrid electric vehicle. We show that with properly tuned parameter values, the model can be extended to different battery types, such as lithium-ion, nickel-metal hydride, and alkaline. The validation results of the model against measured data in terms of power and efficiency at different temperatures are then presented. The model is incorporated with the recovery effect for accurate lifetime estimation. The obtained lifetime estimation results using the proposed model are similar to the ones predicted by the Rakhmatov and Virudhula battery model on a given set of typical loads at room temperature. A possible incorporation of the cycling effect, which determines the battery cycle life, in terms of the maximum available energy approximated at charge/discharge nominal power level is also suggested. The usage of the proposed model is computationally inexpensive, hence implementable in many applications, such as low-power system design, real-time energy management in distributed sensor network, etc. En ligne : http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=5552150&sortType%3Das [...] [article] Development and validation of a battery model useful for discharging and charging power control and lifetime estimation [texte imprimé] / Agarwal, V., Auteur ; Uthaichana, K., Auteur ; DeCarlo, R.
