Abstract

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.
