Abstract
(EN)
A current sensor diagnosis apparatus according to one embodiment of the present invention is an apparatus for diagnosing an error of a plurality of current sensors connected to a secondary battery cell. According to the present invention, an offset difference and current values of two current sensors are used so as to diagnose an error of current sensors, and thus an error of a current sensor can be diagnosed in the same manner regardless of the type of a system using the current sensor, the type of a current source, a voltage characteristic, and the like, and, particularly, the apparatus can be easily applied to various systems comprising a plurality of current sensors.

Un mode de réalisation de la présente invention concerne un appareil de diagnostic de capteur de courant constituant un appareil permettant de diagnostiquer une erreur d'une pluralité de capteurs de courant connectés à une cellule de batterie secondaire. Selon la présente invention, une différence de décalage et des valeurs de courant de deux capteurs de courant sont utilisées de façon à diagnostiquer une erreur de capteurs de courant, et ainsi une erreur d'un capteur de courant peut être diagnostiquée de la même manière quel que soit le type d'un système utilisant le capteur de courant, le type d'une source de courant, une caractéristique de tension, etc., et en particulier, l'appareil peut être facilement appliqué à divers systèmes comprenant une pluralité de capteurs de courant.
