Activation device for an electric battery unit and electric battery unit with at least one activation device

A battery unit, in particular, for a torpedo, comprising:

• a battery cell section and multiple operating supply reservoirs connected to the battery cell section, and activation devices corresponding with the operating supply reservoirs, wherein the activation devices can be pneumatically actuated by means of a pressure reservoir of the battery unit, which is attached to an operable sealing mechanism;
• wherein the activation devices comprise an operating supply connection to which an operating supply reservoir can be connected, the operating supply connection comprising a movably arranged cutting element which can be pneumatically actuated by means of an actuation element via a pneumatic connection with the activation device, and a sealing element arranged in the path of travel of the cutting element, which controls the operating supply connection;
• the activation devices further comprise a pneumatic outlet, which, depending on the position of the actuation element, can be fluidically connected to the pneumatic connection;
• and
• the activation devices of the operating supply reservoirs are pneumatically switched in a series connection.
