1. A method for checking the plausibility of a current measurement between an electrical energy storage system (41) and an electrical consumer (42), wherein a capacitor (43) and a switching element (44) are arranged between these two elements, the method comprising the steps of:
a) ascertaining a first current value by measuring an electrical current between the electrical energy storage system (41) and the electrical consumer (42);
b) actuating the switching element (44) to isolate the electrical energy storage system (41) from the electrical consumer (42) so that the electrical consumer (42) is supplied with electrical energy by the capacitor (43);
c) ascertaining a first electrical voltage at the capacitor (43);
d) ascertaining a second current value depending on the ascertained voltage;
e) checking the plausibility of the current measurement by comparing the first current value with the second current value.
