Abstract

Un système et un procédé de détection des défaillances de connexion de batterie reposent sur la mesure de la température de corps de cellule de batterie et de la température de connecteur de batterie à un courant mesuré. La différence entre ces deux températures est calculée en utilisant un comparateur contrôlé par logiciel. Le comparateur compare la différence mesurée à une différence sûre prédéterminée pour le courant mesuré. Si la valeur mesurée dépasse la valeur sûre prédéterminée, une alarme est générée. Dans un mode de réalisation de linvention, la différence entre les deux températures est comparée à une différence sûre prédéterminée indépendante des mesures de courant.
