Abstract:
La présente invention concerne un procédé optimisé de gestion thermique de la température de surface et de cœur d'un système électrochimique dans les conditions de fonctionnement nominal et extrême. Pour des applications concernant les véhicules hybrides et électriques, l'état thermique (T) en surface et au cœur des éléments constitutifs du système doit être maîtrisé pour éviter tout risque d'emballement thermique, d'incendie et d'explosion. La reconstruction des caractéristiques internes qui ne sont pas directement mesurables, comme la température au cœur des éléments, est faite à travers l'utilisation d'un modèle électrique, thermique et d'emballement thermochimique de la batterie. La méthode peut être utilisée d'une façon synchrone au fonctionnement de la batterie elle- même (temps réel) grâce à un modèle à paramètres concentrés (OD), ou hors ligne, par exemple dans le cadre d'une calibration, d'une optimisation ou d'une validation de stratégies de gestion énergétique et thermique. La méthode permet là simulation du comportement thermique, électrique et d'emballement thermochimique d'une batterie et peut être également utile au dimensionnement de la batterie.
