Title (EN) BATTERY PACK COMPRISING ELECTRONIC MEANS FOR CALCULATING AT LEAST A WEAR PARAMETER
(FR) BLOC-BATTERIE COMPRENANT DES MOYENS ÉLECTRONIQUES POUR CALCULER AU MOINS UN PARAMÈTRE D'USURE
Abstract:
(EN) Battery pack comprising a plurality of cells electrically connected to each other, and further comprising at least a current sensor configured so that it measures the discharge current of said battery pack, at least a current sensor configured so that it measures the charge current of at least a cell of said battery pack, at least a voltage sensor configured so that it measures the voltage of at least a cell of said battery pack, at least a temperature sensor configured so that it measures temperature of at least a cell of said battery pack, electronic means configured for measuring time as well as for acquiring and storing data measured by said current, voltage and temperature sensors, said electronic means being configured for calculating at least a wear parameter, wherein said at least wear parameter is calculated as the sum of the contribution to wear of at least a cell of said battery pack of each single total or partial charging and discharging cycle, and wherein said contribution of each single total or partial charging cycle is calculated as a function of the charging time, voltage of said at least one cell during said charging time, charge current and temperature during the charging step and wherein said contribution of each single total or partial discharging cycle is calculated as a function of the discharging time, battery voltage during said discharging time, discharge current and temperature during the discharging step.
(FR) L'invention concerne un bloc-batterie comprenant une pluralité de piles reliées électriquement l'une à l'autre, et comprenant en outre au moins un capteur de courant conçu pour mesurer le courant de décharge dudit bloc-batterie, au moins un capteur de courant conçu pour mesurer le courant de charge d'au moins une pile dudit bloc-batterie, au moins un capteur de tension conçu pour mesurer la tension d'au moins une pile dudit bloc-batterie, au moins un capteur de température conçu pour mesurer la température d'au moins une pile dudit bloc-batterie, des moyens électroniques conçus pour mesurer une durée et pour acquérir et stocker des données mesurées par lesdits capteurs de courant, de tension et de température, lesdits moyens électroniques étant conçus pour calculer au moins un paramètre d'usure, ledit au moins un paramètre d'usure correspondant à la somme de la contribution à l'usure d'au moins une pile dudit bloc-batterie de chaque cycle de charge et de décharge totale ou partielle individuel, et ladite contribution de chaque cycle de charge totale ou partielle individuel étant calculée en fonction du temps de charge, de la tension de ladite au moins une pile pendant ledit temps de charge, du courant de charge et de la température pendant l'étape de charge, et ladite contribution de chaque cycle de décharge totale ou partielle individuel étant calculée en fonction du temps de décharge, de la tension de batterie pendant ledit temps de décharge, du courant de décharge et de la température pendant l'étape de décharge.
