Abstract[English]
Pressure-control apparatuses for applying pressure to test specimens during testing, such as cycle testing of secondary battery cells and material-property testing of various materials. In some embodiments, a pressure-control apparatus includes one or more of a screw-drive mechanism that is driven by a stepper motor, a flexible drive coupling located between the motor and the screw-drive mechanism, and limit-switch circuitry that includes a pull-down-resistor arrangement that uses components of the pressure-control apparatus as electrical contacts. In embodiments for battery-cell testing, a pressure-control apparatus includes an apparatus controller that receives information from a cycler and that controls operations of the stepper motor based on that information, at time in conjunction with pressure signals from a pressure-sensing system located onboard the pressure- control apparatus.[French]
L'invention concerne des appareils de commande de pression pour appliquer une pression à des échantillons de test pendant un test, tels qu'un test de cycle de cellules de batterie secondaire et un test de propriété de matériau de divers matériaux. Dans certains modes de réalisation, un appareil de commande de pression comprend un ou plusieurs éléments parmi un mécanisme d'entraînement à vis qui est entraîné par un moteur pas à pas, un couplage d'entraînement flexible situé entre le moteur et le mécanisme d'entraînement à vis, et un circuit de commutation de limite qui comprend un agencement de résistance d'excursion basse qui utilise des composants de l'appareil de commande de pression en tant que contacts électriques. Dans des modes de réalisation pour un test de cellule de batterie, un appareil de commande de pression comprend un dispositif de commande d'appareil qui reçoit des informations provenant d'un cycleur et qui commande des opérations du moteur pas à pas sur la base de ces informations, à temps conjointement avec des signaux de pression provenant d'un système de détection de pression situé à bord de l'appareil de commande de pression.
