An underbody unit (10) for reinforcing a motor vehicle body of a motor vehicle has a floor body (12) that is connectable to the motor vehicle body for dissipating loads of the motor vehicle body. The floor body (12) has an upper side (32) for supporting battery cell units (18) of a traction battery for driving the motor vehicle purely electrically and at least one cooling channel (26) for cooling the upper side (32). The floor body (12) and the underbody unit (10) form a supporting plate of a battery housing and can: support the battery cells (18) of the traction battery, form an armor plating to protect the battery cells (18) and define a heat exchanger that can actively and/or passively cool the battery cells (18) with the aid of the cooling channel (26).
