Abstract

The invention relates to a method for operating an electric energy store (1), to an electric energy store (1), and to a device, having an electric energy storage module (18), a switch unit (4), and a first and second connection (5, 7). The method has the following steps which follow one another chronologically: in a first step, a signal of a sensor of the electric energy store (1) is evaluated; in a second step, a critical state of the electric energy store (1) is ascertained; in a third step, an electrically conductive connection between the electric energy storage module (18) and the first and second connection (5, 7) is interrupted in the charge direction by means of the switch unit (4), while simultaneously the electrically conductive connection between the electric energy storage module (18) and the first and second connection (5, 7) remains connected in the discharge direction.
