A cooling tank installation () for a liquid cooling of a charging station for electrically powered motor vehicles includes at least one reservoir () for receiving an environmentally hazardous cooling medium. The reservoir () is inserted in a retention vessel () for retaining a quantity of leakage from the reservoir (), and a receiving volume for receiving the entire liquid volume of the reservoir () is formed between the reservoir () and the retention vessel (). The retention vessel () is inserted in an outer vessel () that provides support with respect to earth loads. An absorption body () is provided in the outer vessel () between the retention vessel () and the outer vessel () in the direction of gravity for absorbing moisture, and a moisture sensor detects moisture of the absorption body ().

The invention relates to an energy store comprising an arrangement of battery cells () in an installation housing (), wherein groups (I, II, III) of battery cells () follow one another in the direction of the longitudinal axis () of the installation housing (). Within each group (I, II, III) of battery cells (), a flow path () for cooling air is formed, which flow path connects a feed air opening () for a cooling air flow () to a cooling air outlet (). In order to achieve effective cooling, first feed air openings () and a first cooling air outlet () are associated with a first flow path () in a first group (I) of battery cells () and second feed air openings () and a second cooling air outlet () are associated with a second flow path () in a second group (II) of battery cells (). The cooling air flow () of the first flow path () is led to the first cooling air outlet () separately from the cooling air flow () of the second flow path () and the cooling air flow () of the second flow path () is led to the second cooling air outlet () separately from the cooling air flow () of the first flow path ().

A digital system or device includes a battery pack as an exemplary functional subunit. In a warranty case determined by an electrical load test for determining its actual charge capacity, a battery check program initializes, via the operating system and an underlying printer, a printout of a warranty certificate. This certificate form, in particular, contains a UID of the underlying battery pack gathered from a ROM implemented in the battery pack. Before generating the printout of the certificate, the UID gathered from the ROM is coded e.g. by the battery check program and only the coded UID is printed. The printout of the warranty certificate thereafter will be delivered to the warranty service provider by the user. After having received the delivered warranty certificate and having checked validity of the user's warranty claim by means of the coded UID the warranty service provider sends a replacement battery pack back to the user. As a consequence, the user can replace the battery pack on its own and therefore does not have to deliver the replaced battery pack to the warranty service provider.

In a casting method for producing a cast part, a melt to be cast is filed into a container and the mold is connected seal-tightly to the container. The mold and the container are rotated together so that the melt flows from the container into the mold. The mold and the container are separated from another and the cast part is removed from the mold. The casting plant for performing the method has a mold that is pivotably supported about a first axis of rotation to perform a first movement that is a pivot movement in a first movement direction. A container is pivotably supported about a second axis of rotation. The mold is supported so as to be movable by a second movement in a second movement direction.

The computer system initially operates in a fully operational mode in which an operating system in the computer system is operating and the computer system executes one or more user applications installed in the computer system. In response to a predefined time interval lapsing, the computer system automatically switches from the fully operational mode to a limited operational mode in which the one or more user applications are terminated, the operating system is shut down, and a BIOS within the computer system solicits entry of a password by a user. If the user fails to enter a valid password, operation of the operating system and execution of the one or more user applications are prevented. If a user attempts to activate the computer system for which the time interval has already lapsed, a BIOS within the computer system boots up, determines that the computer system is currently set for a limited operational mode, prevents boot up of an operating system of the computer system, and solicits a password from a user. If the user fails to enter a valid password, the BIOS continues to prevent boot up of the operating system. If the user enters a valid password, the operating system boots up and executes one or more user applications within the computer system.
