VRLA battery virtual reference electrode / Hunter, P.M. in IEEE transactions on energy conversion, Vol. 23 n°3 (Septembre 2008)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 n°3 (Septembre 2008) . - pp. 879 - 886 Titre : VRLA battery virtual reference electrode : battery float charge analysis Type de document : texte imprimé Auteurs : Hunter, P.M., Auteur ; Anbuky, A. H., Auteur Année de publication : 2008 Article en page(s) : pp. 879 - 886 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Electrochemical electrodes  lead acid batteries Résumé : This paper investigates the problems and deficiencies with present valve-regulated lead-acid (VRLA) battery float charge techniques. The requirements and goals of float charge are identified, and a mechanism for assessing the achievement of these goals is provided. An electrical equivalent model of a VRLA cell's float charge operational region is developed. This model replicates both the steady-state and transient responses of a float charging VRLA cell. Based on the response of each electrode within a cell to an applied stimulus, a simple test-and-analysis procedure is developed. This procedure extracts reference-electrode-like polarization information from any conventional 2 V VRLA cell in float service. This test procedure is applied to the terminals of a standard cell, and does not require any physical modification to the cell.
