Abstract

An underbody protection apparatus (2) to be arranged below a traction battery (6) on the underbody of an at least semi-electrically driveable motor vehicle (100), comprising an underbody protection plate (8) for protecting the underbody of the motor vehicle (100), a gas-conducting structure (10) arranged between the traction battery (6) and the underbody protection plate (8) and arranged on the underbody protection plate (8) for conducting a gas (16) exiting from the traction battery (6) along the underbody protection plate (8), wherein the gas-conducting structure (10) is arranged on the traction battery (6) such that a gas (16) can be introduced into the gas-conducting structure (10) via a degassing outlet (12) of the traction battery (6), wherein the gas-conducting structure (10) comprises a plurality of branching points (18) for branched conduction of the gas (16) exiting from the traction battery (6) along the underbody protection plate (8), wherein the gas-conducting structure (10) comprises at least one gas outlet opening (14) for discharging the gas (16) exiting from the traction battery (6) and being conducted along the underbody protection plate (8).
