Title (EN) MEDICAL DEVICE WITH BATTERY TESTING
(FR) DISPOSITIF MÉDICAL COMPRENANT UNE UNITÉ DE TEST DE BATTERIES
Abstract:
(EN) Disclosed is a body-wearable medical device (1), the medical device being designed to be powered by a battery (2). The medical device includes battery contacts to contact the battery, a capacitor (12) in parallel electrical arrangement with the battery contacts and a control unit (14). The control unit (14) is configured to control operation of the medical device (1). The control unit (14) includes a battery testing unit (141), the battery testing unit (141) being configured to execute a battery test. The battery test includes determining a first capacitor voltage (U1) as value of a capacitor voltage (U) at a first point in time (t1), determining a second capacitor voltage (U2) as value of the capacitor voltage (U) at a second point in time (t2), subsequent to the first point in time (t1); drawing, between the first point in time (t1) and the second point in time (t2), a test current, wherein the first point in time (t1) is determined by the beginning of drawing the test current and wherein the second point in time (t2) is determined such that the capacitor voltage (U) at the second point in time (t2) is steady with the test current being drawn; determining a charging state of the battery from a voltage difference between the first capacitor voltage (U1) and the second capacitor voltage (U2) and/or from a time difference between the first point in time (t1) and the second point in time (t2).
(FR) L'invention concerne un dispositif médical vestimentaire corporel (1), le dispositif médical étant conçu pour être alimenté par une batterie (2). Le dispositif médical comprend des contacts de batterie permettant de connecter la batterie, un condensateur (12) en agencement électrique parallèle avec les contacts de batterie et une unité de commande (14). L'unité de commande (14) est conçue pour commander le fonctionnement du dispositif médical (1). L'unité de commande (14) comprend une unité de test de batterie (141), l'unité de test de batterie (141) étant conçue pour exécuter un test de batterie. Le test de batterie comprend les étapes consistant à déterminer d'une première tension de condensateur U 1 en tant que valeur d'une tension de condensateur U à un premier moment tl, à déterminer une seconde tension de condensateur U2 en tant que valeur de la tension de condensateur U à un second moment t2, ultérieur au premier moment tl; à prélever, entre le premier moment tl et le second moment t2, un courant de test, le premier moment tl étant déterminé par le début du prélèvement du courant de test et le second moment t2 étant déterminé de telle sorte que la tension de condensateur U au second moment t2 est stable avec le courant de test prélevé; à déterminer un état de charge de la batterie à partir d'une différence de tension entre la première tension de condensateur U 1 et la seconde tension de condensateur U2 et/ou à partir d'une différence temporelle entre le premier moment tl et le second moment t2.
