Title
(EN) STATE OF CHARGE DEPENDENT PLATING ESTIMATION AND PREVENTION
(FR) ESTIMATION ET PRÉVENTION DE PLACAGE DÉPENDANT DE L'ÉTAT DE CHARGE
Abstract
(EN) A battery system (12) includes a lithium ion battery (30) configured to couple to an electrical system (26), and a battery management system (36) configured to electrically couple to the lithium ion battery (30) and to control one or more recharge parameters of the lithium ion battery (30). The battery management system (36) is programmed with an electrochemical model (72), and the battery management system (36) is configured to monitor parameters of the lithium ion battery (30), and to control the one or more recharge parameters of the lithium ion battery (30) based on the electrochemical model (72) and the one or more monitored parameters. The electrochemical model (72) determines lithium plating reaction kinetics at an anode (50) of the lithium ion battery (30), determines a quantity of plated lithium at the anode (50) of the lithium ion battery (30), or both, and indicates a relationship between the one or more monitored parameters and the lithium plating reaction kinetics, the quantity of plated lithium, or both.
(FR) Selon l'invention, un système de batterie (12) est pourvu d'une batterie au lithium-ion (30) conçue de façon à se coupler à un système électrique (26), et d'un système de gestion de batterie (36) conçu de façon à être couplé électriquement à la batterie au lithium-ion (30) et à commander au moins un paramètre de recharge de la batterie au lithium-ion (30). Le système de gestion de batterie (36) est programmé avec un modèle électrochimique (72) et conçu de façon à surveiller des paramètres de la batterie au lithium-ion (30) et à commander ledit paramètre de recharge de la batterie au lithium-ion (30) sur la base du modèle électrochimique (72) et desdits paramètres surveillés. Le modèle électrochimique (72) détermine la cinétique de réaction de placage de lithium au niveau d'une anode (50) de la batterie au lithium-ion (30) et/ou détermine une quantité de lithium plaqué au niveau de l'anode (50) de la batterie au lithium-ion (30), et indique une relation entre lesdits paramètres surveillés et la cinétique de réaction de placage de lithium et/ou la quantité de lithium plaqué.
