Abstract: The present invention relates to a battery management system, a battery comprising the battery management system and a method for controlling discharge of at least one battery cell. A battery management system (100) comprises a control circuit (102), which is configured to monitor a voltage of at least one battery cell (108), and a connector circuit (104), which is configured to electrically connect the control circuit (102) to the at least one battery cell (108). The control circuit (102) is mounted on a first component carrier (118) and comprises a first electronic interface having at least one contact (128) for electrically connecting a mating contact of the connector circuit.

Abstract: The invention relates to a method for managing information dealing with a medical test for assessing a predetermined medical condition by means of a distributed system (100) comprising a plurality of communication devices (210, 312, 322, 410), the method comprising obtaining by a user communication device (210) information on an access code provided in a test-kit for assessing a predetermined medical condition, the user communication device (210) being configured for receiving and displaying messages addressed to a unique identifier. Further, the method comprises providing instructions relating to analysis of the medical sample. A negative analysis result is communicated to the user communication device (210) of the user. In case of a positive analysis result, consultation by a medical entity is established. Further aspects relate to a user communication device, a computer program product, a central server and a medical test-kit for use with the proposed method.

Abstract: The present invention relates to a contactor device (100), which is capable of changing a connection state of at least two battery modules (502(1), 502(2)) of a high voltage energy storage system (10) between a series connection and a parallel connection, and to an energy storage system (10) comprising the contactor device (100). The contactor device (100) comprises two first terminals (102, 104) for electrically connecting at least one of a load and a charger, two second terminals (106, 108) for electrically connecting a first battery module (502(1)), and two third terminals (110, 112) for electrically connecting a second battery module (502(2)).

Abstract: The present invention relates to a contactor device for high voltage applications, an energy storage system comprising the contactor device and a corresponding method for controlling the contactor device. A contactor device (100) comprises at least one fixed contact (106), at least one moveable contact (108), which is configured to move between an open position and a closed position, wherein in the closed position, the at least one moveable contact (108) electrically contacts the at least one fixed contact (106), and at least one first actuator (110, 120), which is configured to reversibly move the at least one moveable contact between the open position and the closed position. The contactor device (100) further comprises at least one second actuator (202) which is configured to move the at least one fixed contact (106) into a fired position, wherein in the fired position, the at least one fixed contact (106) is permanently disconnected from the at least one moveable contact (108).
