Abstract

The invention relates to an electrochemical energy store (301, 401), comprising a first attachment element (306, 308, 409, 410, 411, 412) which is designed in such a manner that, when such a first electrochemical energy store (319), or at least one such first attachment element of said first such electrochemical energy store, is pressed against a second such electrochemical energy store (320) or against at least one second such attachment element of said second such electrochemical energy store (320), an attachment of the first electrochemical energy store to the second electrochemical energy store takes place.

Claims
