摘要： A traction battery system of an electrically operable motor vehicle is configured in the form of an underfloor battery and has at least one first battery module and one second battery module. The traction battery system includes a battery assistant module that is designed for operating the battery modules. The battery modules and the battery assistant module, which have an assistant module housing, are oriented in series in relation to one another in the direction of a body longitudinal axis of a motor vehicle body, and can be arranged between a first sill and a second sill of the body. The battery assistant module has a load-transmitting element for transmitting forces acting on side elements of the body, which load-transmitting element extends from the first sill to the second sill in the direction of a body transverse axis of the body.

摘要： A traction battery module for a vehicle, with a battery housing, the battery housing having a preferably extruded housing part with hollow chambers formed in it, which extend alongside one another along a central longitudinal direction and are open at the ends. The hollow chambers respectively define a cooling channel. At least one cooling connection adapter is provided, having a non-circular outer circumferential surface in an insertion portion and having been introduced or pressed at the end into one of the hollow chambers with an inner circumferential surface corresponding to the outer circumferential surface of the insertion portion. A pressing engagement is formed, at least in certain portions, between the outer circumferential surface and the inner circumferential surface.

摘要： A partial body for an at least part-electrically operated motor vehicle includes a first receiving portion for a traction battery and a second receiving portion for an electric drive unit. The receiving portions are arranged behind one another with respect to a vehicle longitudinal direction and are arranged at least partially at the same height with respect to a vehicle vertical direction. Here, a body transverse wall, which is of double-walled design at least in certain portions and which extends in the vehicle vertical direction and vehicle transverse direction, is arranged between the first and second receiving portion such that, in the event of an accident-induced displacement of the drive unit in the direction of the traction battery. The drive unit can be supported on the body transverse wall in a targeted manner.
