Abstract:
The invention relates to a lithium-ion energy store (1), comprising an electrode (2, 3) having a main segment (2) and having a measurement segment (3) electrically isolated from the main segment (2), a counter-electrode (4), and a separator (5) between the electrode (2, 3) and the counter-electrode (4), wherein a measuring cell (3, 4), which forms part of the lithium-ion energy store (1), comprises the measuring segment (3) of the electrode (2, 3), a counter-electrode measuring segment, which is opposite the measuring segment (3) of the electrode (2, 3) with respect to the separator (5), and a segment of the separator (5) in arranged between the measuring segment (3) of the electrode (2, 3) and the counter-electrode measuring segment, and a main cell (2, 4), which forms part of the lithium-ion energy store (1), comprises the main segment (2) of the electrode (2, 3), a counter-electrode in main segment, which is opposite the main segment (2) of the electrode (2, 3) with respect to the separator (5), and a segment of the separator (5) arranged between the main segment (2) of the electrode (2, 3) and the counter-electrode main segment, wherein the lithium-ion energy store (1) has a measuring device (110) for a depth of discharge and/or a state of charge of the measuring cell (3, 4).
