FLUID DRAINAGE ARRANGEMENT FOR A BATTERY

A fluid drainage arrangement for a battery arrangement, the fluid drainage arrangement having a fluid inlet, a collecting chamber, a membrane, a labyrinth chamber and a fluid outlet. The membrane is provided between the collecting chamber and the labyrinth chamber and has a closed state (Z) and an open state (Z). The membrane is designed, in the closed state (Z), to collect a coolant, which passes into the collecting chamber via the fluid inlet, in the collecting chamber until the membrane, at a predetermined first differential pressure between a side of the membrane that is assigned to the collecting chamber and a side of the membrane that is assigned to the labyrinth chamber, transitions from the closed state (Z) into the open state (Z) and allows drainage of the coolant via the labyrinth chamber to the fluid outlet.
