Abstract

The invention discloses a traction battery system of an electrically operable motor vehicle. A traction battery (7), which is configured in the form of an underfloor battery, has at least one first battery module(8) and one second battery module (9). The traction battery system includes a battery assistant module (13) that is designed for operating the battery modules (8, 9). The battery modules (8, 9) and the battery assistant module (13) are oriented in series in relation to one another in the direction of a body longitudinal axis of a motor vehicle body (3), and can be arranged between a first sill (4) and a second sill (5) of the body (3). The battery assistant module (13) has a load-transmitting element (18) for transmitting forces acting on side elements of the body (3), which load-transmitting element extends from the first sill (4) to the second sill (5) in the direction of a body transverse axis (Y) of the body (3). A motor vehicle having the electric drive is also disclosed.

Description

technical field [0001] The present invention relates to a traction battery system for a motor vehicle. The invention also relates to a motor vehicle with an electric drive. Background technique [0002] Traction battery systems for motor vehicles are known. This involves a plurality of battery modules which have a plurality of battery cells which are designed for electric or partial drive in the form of a hybrid drive. A plurality of battery cells are bundled into a battery module, wherein the plurality of battery modules are accommodated in the battery housing of the traction battery. The traction battery system is accommodated in the accommodation space of the body of the motor vehicle. [0003] The publication DE 10 2011 109 024 A1 discloses a traction battery system for a motor vehicle, the battery modules of which and the associated components (eg cooling device, electrical converter, inverter and DC converter) are accommodated in a place that can be accommodated In...
