Abstract: A battery housing for a battery module of a traction battery of a motor vehicle has (i) a housing for enclosing at least one battery cell of the battery module, (ii) at least one cooling groove which is formed in at least one housing wall of the housing after which is open away from the battery cell and which serves for conducting a cooling fluid, and (iii) a cover which is configured as a planar plate and which is connected to the housing wall and which serves for closing the at least one cooling groove. Owing to the cooling groove formed in the housing wall, the cover can be configured as an inexpensive planar plate, such that cooling of a battery module is made possible with little outlay in terms of production.

Abstract: A process and apparatus for the measurement of parameters in reactors having moving stirrers which contain probes in the reactor interior, wherein at least two probes connected via a multiplexer to a sensor signal amplifier by connecting cables located in the moving stirrers are installed on the surface of the moving stirrers, and the measurement data obtained by the probes are passed via the connecting cables to a sensor signal amplifier and from thence are passed on to an electronic evaluation unit by non-contact, inductive signal transmission by means of a contactless sensor tap.
