Beschreibung
Zusammenfassung:	A battery housing includes a valve device for pressure equalization and for letting out a hot gas of a battery cell. The valve device has a valve seat in the form of a gas release opening in a housing wall of the battery housing and a valve body. The valve body closes the gas release opening when in a closed position, can be moved by a pressure-difference-induced internal pressure increase into a first open position in which the valve body reversibly opens the gas release opening to provide pressure equalization, and can be moved by a hot-gas-induced internal pressure increase into a second open position in which the valve body irreversibly opens the gas release opening to let out the hot gas.
