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

A battery unit, 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 are configured to 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 each comprise an operating supply connection configured to be connected to an operating supply reservoir, the operating supply connection comprising a movably arranged cutting element which is configured to be pneumatically actuated by means of an actuation element via a pneumatic connection with the respective activation device, and a sealing element arranged in a path of travel of the cutting element, which controls the operating supply connection;
• the activation devices each further comprise a pneumatic outlet, which, depending on the position of the actuation element, is configured to be fluidically connected to the pneumatic connection;
• each actuation element comprises an actuator piston which bears the cutting element, the pneumatic outlet is within a path of travel of the actuator piston, and the perimeter of the actuator piston operates the pneumatic outlet,
• each cutting element is arranged inside a blade housing at the end of a piston rod connected to the actuator piston,
• each piston rod extends through a partition between a pneumatics housing and the blade housing, wherein the partition incorporates a guide for the piston rod,
• and
• the activation devices of the operating supply reservoirs are pneumatically switched in a series connection.
