Claim 0:
1. A method for operating an electrical energy store (12), which comprises a storage cell (14) for storing electrical energy and a control unit (15), the method comprising:
detecting a current (24) flowing through an electrical line of the electrical energy store (12);
estimating an exceedance time once the current (24) exceeds a pre-threshold value (23);
interrupting, via a safety switch (16), the electrical line of the electrical energy store (12) when the current (24) flowing through the electrical line is below a predefined threshold value (22), wherein the pre-threshold value (23) is smaller than the predefined threshold value (22); and
activating the safety switch (16) when the estimated exceedance time, in which the current (24) is above the predefined threshold value (22), exceeds a predefined tolerance time, wherein the exceedance time is not longer than the tolerance time.
