A method of producing a battery with a prismatic battery housing includes assembling a battery housing from two prefabricated housing parts, of which the first housing part includes at least a partial region of the element including the at least one through hole as well as at least a partial region of a second element, bordering on the element including the at least one through hole, and the second housing part includes all elements and/or partial regions of elements not part of the first housing part.

A method of determining a state or a state change of an electrochemical energy storage device that includes a housing composed of a multilayer composite film, wherein the housing includes a first housing part and a second housing part composed of the multilayer composite film, which parts are joined to one another, and together enclose a hollow space in which the composite is arranged, and the composite film includes a ply composed of a metal layer and also two plies composed of polymer, with the metal layer being arranged between the two polymer plies, wherein to determine the state or the state change, an electric potential is applied to the metal layers of the first housing part and the second housing part so that an electric field arises between the metal layers and an electrical parameter influenced by a change of a spacing between the metal layers is determined.

A battery of modular construction that stores electrical energy includes a battery housing, a module assembly including at least two battery modules, each with at least one positive and at least one negative electrode, and a pressing means. A method of safety operation of the battery includes equipping the battery with at least one safety means that triggers a reduction in the mechanical pressure exerted onto the battery modules when there is a defect in at least one of the battery modules.

Battery of modular construction having improved safety properties

A battery includes a housing, at least one individual cell arranged in the housing and including at least one positive electrode and at least one negative electrode, a positive pole stud passed through the housing and electrically connected to the at least one positive electrode and/or a negative pole stud passed through the housing and electrically connected to the at least one negative electrode, at least one electrical switch which can be pneumatically operated and changes its switching state in the event of an increase in pressure within the housing beyond a threshold value and thereby interrupts the electrical connection between at least one of the pole studs and an associated at least one electrode, and a resetting device with which an electrical connection which is interrupted as a result of a change in the switching state can be re-established without the housing having to be opened.

Battery with a safety device which can be reset, and also suitable pole stud for the battery

A head-mounted optical direct visualization system has at least one optical deflecting device () with an optical end element () for deflecting a virtual image generated by an image source () onto the optical end element (). The virtual image is emitted through the optical end element into the field of view in front of the eyes of the user. The optical deflecting device () is attached to the head of the user with the aid of a frame (). The task of the invention is to configure such a conventional direct visualization system so as to be better adaptable to the requirements of the anatomical and optical features of the user and the application-specific viewing requirements. This task is solved with an adjusting device (), which is fixed to the frame (), for variably changing the position of at least the optical end element () essentially in a plane parallel to the field of view of the user.
