A battery housing for a motor vehicle battery includes a housing for accommodating at least one battery cell in an interior space delimited by the housing; a drainage device communicates with the interior space; a detection device detects an air moisture content and/or a liquid fill level in the interior space; and an evaluation unit which is connected to the detection device. The evaluation unit is connected to the drainage device and the drainage device is designed to open and/or close in a manner dependent on the liquid fill level ascertained in the evaluation unit. By way of the linking of the drainage device to the detection device by way of the evaluation unit, it can be ensured that the drainage device is opened only in particularly expedient situations, such that good protection of a motor vehicle battery against moisture is made possible.

Battery housing for a motor vehicle battery

A battery module () of a traction battery of a motor vehicle has a module housing () that is open at opposite ends and closable at the ends. Multiple battery cells () are received in the module housing () and form battery cell packs (). At least one first battery cell pack () is inserted into the module housing () via a first of the open ends of the module housing (), and at least one second battery cell pack () is inserted into the module housing () via a second of the open ends of the module housing (). At least one centering device () is inserted into an opening () of the module housing (). The at least one centering device () aligns the at least one first battery cell pack () and the at least one second battery cell pack () in the module housing ().

An apparatus for storing electric energy for a motor vehicle includes a plurality of energy storage modules and a main body which can be fastened to the motor vehicle. Each energy storage module includes energy storage for storing the electric energy and a carrier, in which the energy storage is arranged. The carrier is fastened in an individually detachable manner to the main body in the state in which it is fastened to the motor vehicle, with the result that a first one of the energy storage modules can be removed from the apparatus without it being necessary for the carrier of a second one of the energy storage modules to be detached from the main body.

Apparatus for storing electric energy for a motor vehicle

A holding apparatus for securing a fan for cooling a component of a vehicle, having a main body made from foam material. The main body has a fan receptacle for receiving the fan in a positively locking manner at least in sections. The fan receptacle has an air inlet for feeding in air to the fan and an air outlet for discharging air from the fan. The main body also has at least one inlet opening with an adjoining inlet duct and at least one outlet opening with an adjoining outlet duct. The inlet duct is in a fluid-communicating connection with the air inlet and the outlet duct is in a fluid-communicating connection with the air outlet.

Holding apparatus for securing a fan for cooling a component of a vehicle

An underbody of an electrically driven motor vehicle, with a vehicle supporting structure, which is bounded laterally in a transverse direction of the vehicle by two vehicle sills between which a multiplicity of battery modules is arranged, which battery modules are assigned a battery supporting structure and at least one battery temperature control device, and with supply and removal devices for a temperature control medium. The supply and removal devices for the temperature control medium are arranged in the region of the vehicle sills.

Underbody of an electrically driven motor vehicle

A motor vehicle battery has a plurality of battery modules (). Each battery module () is fastened to housing walls () of a battery housing (). The battery housing () has at least two housing modules () positioned above one another and formed with housing module walls (). At least some of the mutually adjoining housing module walls () interengage in the manner of toothing to form the housing walls ().

Motor vehicle battery

A motor vehicle battery having at least one battery module () with battery cells () positioned one behind the other and bounded by first walls () at opposite ends of the battery module () and by second walls () at opposite longitudinal sides of the battery module (). Bottom ends of the battery cells () bearing against a cooling plate (). The battery cells () of the battery module () are pressed together between the first walls (). A dummy cell () is positioned between two adjacent battery cells () of the battery module (). A clamping bolt () extends through the dummy cell and presses the battery cells () of the battery module () against the cooling plate () in a second direction perpendicular to the first direction.

Motor vehicle battery comprising dummy cell and cooling plate

A motor vehicle battery has at least one battery module with a plurality of battery cells () that have connection poles and degassing predetermined breaking points (). The battery module also has a common battery module control device () for all of the battery cells () of the battery module. The degassing predetermined breaking points () of the battery cells () are on one side of the battery module and are offset inward in relation to the connection poles of the battery cells to form a recess (). A guide element () is positioned in the recess () and extends along all of the battery cells () of the respective battery module to define a degassing channel () on one side and defining an accommodation space () for the battery module control device () on the other side.

A motor vehicle battery has at least one battery module () with a plurality of battery cells () bounded by battery module walls () of the battery module (). Two opposite battery module walls () of the battery module () are between walls () of a battery housing or walls of a bodywork structure. Deformation elements () fasten the battery module walls () of the respective battery module () indirectly to walls () of the battery housing or of the bodywork structure, and the respective wall () of the battery housing or of the bodywork structure.
