Abstract
Un système de contrôle de pile pour une pile électrolytique solide et métallique, telle qu'une pile lithium-polymère, comprenant des détecteurs de température pour détecter la température des cellules dans la pile, des éléments chauffants pour chauffer les cellules, un contrôleur d'éléments chauffants recevant des signaux des détecteurs de température et contrôlant l'alimentation de courant fourni aux éléments chauffants de façon à maintenir chaque cellule à une température prédéterminée, et un contrôleur d'alimentation qui détecte une demande de puissance de la pile et régler la température prédéterminée en réponse à un niveau de puissance à être fourni par la pile ou à la pile. Le contrôleur d'alimentation permet de régler au moins une température de flottement, une température de charge et une température d'alimentation. Le contrôleur comprend de plus un détecteur de voltage qui détecte un voltage à chaque cellule lorsqu'elles sont actives, et détermine si une des cellules est susceptible d'être endommagée par un usage continu. La pile est débranchée de la prise d'alimentation suite à la confirmation qu'une des cellules pourrait être endommagée.A battery control system for a solid and metallic electrolytic cell, such as a lithium polymer battery, comprising temperature sensors for detecting the temperature of the cells in the cell, heating elements for heating the cells, a controller heating elements receiving signals from temperature sensors and controlling the supply of current supplied to the heating elements so as to maintain each cell at a predetermined temperature, and a power controller which detects a demand for battery power and regulates the temperature predetermined in response to a power level to be supplied by the cell or the cell. The power controller allows you to set at least one float temperature, charge temperature, and feed temperature. The controller further includes a voltage detector which detects a voltage at each cell when they are active, and determines whether one of the cells is likely to be damaged by continuous use. The battery is disconnected from the power outlet following confirmation that one of the cells could be damaged.
