Abstract: A drive or traction battery for a motor vehicle has a battery housing with a top wall and a bottom wall. The bottom wall forms, at least in part, an underbody of the motor vehicle. In the battery housing there is a battery cell layer having a plurality of battery cells, arranged vertically and next to one another, and a support layer, which can also be referred to as a degassing layer, spacer layer, collision protection layer or deformation layer. In each battery cell, at least one degassing opening is formed in the side facing the support layer, and a degassing space, such as a recess, that can hold a certain volume of gas is arranged opposite each degassing opening in the support layer.

Abstract: A drive battery for a motor vehicle has a drive battery housing with a cover wall and a base wall. A battery cell layer with a plurality of battery cells and a supporting layer, which is arranged between the battery cell layer and the base wall, are arranged in the drive battery housing. The battery cell layer further has a battery cell position supporting structure which forms a collision load path in the vertical direction of the drive battery.

Abstract: A passenger motor vehicle has a body with a passenger compartment, and a drive energy accumulator, in particular a drive energy battery. The drive energy accumulator is arranged or mounted on the body from below and at least part of it forms a floor of the passenger compartment. The motor vehicle also has a temperature-control system, and the part of the drive energy store forming the floor of the passenger compartment is designed as a heat exchanger for controlling the temperature of the passenger compartment by way of the temperature-control system.

Abstract: A motor vehicle has a body and a drive energy accumulator. The motor vehicle can be a passenger motor vehicle or a truck, and particularly has an electric drive. The drive energy accumulator can be a drive battery which is also referred to as high-voltage accumulator. The body has a floor assembly with a left-hand longitudinal beam and a right-hand longitudinal beam. Such body longitudinal beams are also referred to as side sills or outer, lower longitudinal beams. The drive energy accumulator has a drive energy accumulator housing, and the drive energy accumulator or the drive energy accumulator housing is mounted to the floor assembly from below. The mounted drive energy accumulator or the mounted drive energy accumulator housing form at least part of a floor of the floor assembly.

Abstract: A coolant discharger for a coolant-carrying pipeline network of an electrical energy storage device has at least one drainage ramp configured to be arranged on a pipeline portion of the pipeline network that is susceptible to a coolant leakage, the drainage ramp is configured to discharge a coolant leaking out from the pipeline portion in the event of a coolant leakage and to divert it away from voltage-carrying components of the electrical energy storage device.

Abstract: A drive battery for a motor vehicle has a drive battery housing which has a top wall and a bottom wall. Located in the drive battery housing are a battery cell layer having a plurality of battery cells arranged vertically and next to one another and a support layer, which can also be referred to as a degassing layer, spacer layer, or deformation layer. The battery cell layer is bonded to the top wall by way of an upper adhesive layer and to the support layer by way of a lower adhesive layer, in particular over a large area, for example over its entire surface. The support layer is also bonded to the bottom wall by way of a further adhesive layer.

Abstract: An assembly for a traction battery of a motor vehicle includes a battery module having a cell composite formed by a plurality of battery cells, wherein degassing regions of the battery cells are located on an upper side of the cell composite for letting out a hot gas from a cell housing of the battery cells; a battery component arranged in a vertical direction above the battery module, such that the upper side of the cell composite is facing an underside of the battery component; and a protective unit having a sheet-metal-type protective region for protecting the battery component from the hot gas and a frame-type support region connected to the protective region. The battery component is secured to the support region and the protective region is arranged between the underside of the battery component and the upper side of the cell composite.

Abstract: A hearing apparatus includes a sound tube with a tube-side coupling element and an earpiece with an earpiece-side coupling element. The tube-side coupling element and the earpiece-side coupling element can be reversibly coupled. The tube-side coupling element has a tube-side pressure canal and the earpiece-side coupling element has an earpiece-side pressure canal, which form a coupled pressure canal in a coupled state of the coupling elements. The tube-side coupling element or the earpiece-side coupling element is supported by at least one pressure element which improves air-tightness of the coupled pressure canal. A coupling element and a hearing device are also provided.

Abstract: The present invention relates to network communication systems for managing client/server connections in a wireless environment. In accordance with the invention, a mobile communication unit (i.e., client), deploys keepalive packets at selected times in order to reset a keepidle timer of a server (e.g., host computer). By periodically resetting the keepidle timer a current connection between the mobile communication unit and server can be maintained as long as desired even when the mobile communication unit is in a power suspend mode. When in a power suspend mode, the mobile communication unit can briefly awake long enough to activate its transmitter and send a keepalive packet to the server to maintain the current connection. In this manner, the mobile communication unit can obtain the power savings of being in primarily a power suspend mode, but still prevent the current connection from timing out.
