The battery arrangement has a degassing channel in which gas escaping from the degassing opening. The degassing channel is arranged below the releasable degassing opening and above the cooling wall with respect to the first direction and is designed in such a way that in case of the gas escape of the gas from the degassing opening, a first part of the gas escaping from the degassing opening chronologically first is introducible into the degassing channel.

Abstract: A prismatic battery cell with a cell housing and several electrodes arranged in an interior of the cell housing, some of which are electrically connected to a first cell terminal accessible from outside the cell housing, and some to a second cell terminal which is also accessible from outside the cell housing. The first cell terminal is arranged on a first side of the cell housing and the second cell terminal is arranged on a second side of the cell housing opposite the first side. One of the cell terminals is arranged on a terminating element which is materially connected to the cell housing and which closes an insertion opening configured in the cell housing, and the terminating element is sealingly connected to the cell housing via a circumferential sealing.

Abstract: An energy storage device for storing electrical energy. The energy storage device has an energy storage housing for receiving at least one battery cell stack and a control device. The at least one battery cell stack has at least two battery cells and is arranged between at least two opposite housing walls of the energy storage housing. The energy storage device has at least one sensor device which is arranged between the at least one battery cell stack and one of the housing walls of the energy storage housing, and which is configured to detect a mechanical pressure exerted by the battery cell stack and the housing wall on one another, and provide this as measurement data to the control device.

Abstract: An energy storage device for storing electrical energy. A housing frame of the energy storage device has respective housing end walls on two opposite end faces of the housing frame. The energy storage device has at least one battery cell stack. Respective stack end plates are arranged on two opposite end faces of the battery cell stack, which end plates are fastened in the housing frame of the energy storage device and by which end plates the battery cell stack is subjected to a compressive pressure. The stack end plates are aligned parallel to the housing end walls. At least one of the stack end plates is separated from a housing end wall located opposite to it by a space free of a battery cell stack.

Abstract: A battery for an at least partially electrically drivable motor vehicle. The battery includes a battery pack with a plurality of battery cells, a frame enclosing the battery pack, which frame at least partially covers each of the battery cells on a shell surface of the respective battery cells, and a battery housing with an insertion opening for receiving the battery pack. The battery further includes a pretensioning device having a pretensioning unit which is designed to apply a pretensioning force onto the battery pack on a first side of the frame.

Abstract: A battery module includes a plurality of individual electrical cells which are arranged within a common housing, wherein an end side of the housing has mechanical connecting elements for connecting the battery module to a temperature-control element which is provided outside the battery module in order to thereby enable good heat transfer between the battery module and the temperature-control element. The mechanical connecting elements are provided as corresponding upper and lower cutouts in the end side of the housing, which upper and lower cutouts are connected to one another by a through-passage, for receiving a connector of which the head can be positioned in the one cutout. The connector can extend vertically along the through-passage and can be connected to a mating piece which can be positioned at least partially in the other cutout and is fixedly connected to the temperature-control element.

Abstract: A method for operating a battery of an at least partially electrically operated/driven functional device, a corresponding battery, and a corresponding functional device. A control unit of the battery receives measurement signals relating to a respective parameter of the battery cells from a plurality of switchable battery cells of the battery. The control unit prepares a location-resolved distribution function of the respective cell parameter within the battery on the basis of the measurement signals. By activating the switching elements of the switchable battery cells according to a predetermined switching rule, the control unit produces a pattern of battery cells switched to active and passive. A predetermined location-resolved distribution function of the respective cell parameter is fulfilled and at least one predetermined secondary condition relating to an operation of the functional device and/or the battery is maintained.

Abstract: A battery for an at least partially electrically operated functional device, including at least one battery cell module, in each of which a predetermined number of battery cells is clamped by a mechanical clamping device to form a cell stack. The clamping device transmits a traction force or a contact pressure corresponding to the traction force to the cell stack by delimiting elements and traction elements. A frame element is arranged in each case between at least two or some or each of the battery cells and/or the respective terminal battery cell and the delimiting element is arranged adjacent to the respective terminal battery cell and associated with it. The frame element includes a circumferential part and a free volume delimited by the circumferential part.
