Abstract

An energy store system, including at least one cell element situated in a cell region having an anode, a cathode and an electrolyte system that is situated between the anode and the cathode and that is particularly at least partially liquid, the anode, the cathode and/or the electrolyte system being configured so that, as a function of a charging or discharging process of the cell element, functioning material is situated in the electrolyte system, and the functional material situated in the electrolyte system being ascertainable qualitatively and/or quantitatively. Because of such an energy store system, operating states of an energy store or a cell may be ascertained particularly simply and accurately. Also described is a related state detection system.

First claim

What is claimed is:

wherein at least one of the anode, the cathode and the electrolyte system are configured so that, as a function of at least one of a charging process and a discharging process of the cell element, functional material is situated in the electrolyte system, and the functional material situated in the electrolyte system is ascertainable at least one of qualitatively and quantitatively;
a light source by which the electrolyte system is at least partially irradiated through the aligned light transmitting regions of the anode and the cathode; and
a detector by which the absorption of the irradiated electrolyte system is analyzable via light from the light source, wherein the anode and the cathode are situated between the light source and the detector.

2. The energy store system of claim 1 , further comprising:
an analytical unit, including the light source and the detector, by which at least one property of at least one of the functional material and the electrolyte system is analyzable for at least one of the qualitative and quantitative ascertainment of the functional material situated in electrolyte system.

3. The energy store system of claim 1 , wherein there is a detection range, situated outside a cell region and including the electrolyte system, for the at least one of the qualitative and quantitative ascertainment of functional material situated in the electrolyte system.

4. The energy store system of claim 2 , wherein the cell region, and the analytical unit are surrounded by a housing.

5. The energy store system of claim 1 , wherein the cell region is surrounded by a housing, which has at least one light-transmitting region aligned with the aligned light transmitting regions of the anode and the cathode, the light source and the detector being positioned on an outside of the housing.

6. The energy store system of claim 1 , wherein at least one of the following is satisfied: (ii) the light source includes a light-emitting diode; and (ii) the detector includes a phototransistor.

7. The energy store system of claim 1 , wherein the light source emits light in a wavelength range of the spectrum of the UV/VIS range.

8. The energy store system as recited in claim 1 , wherein the cell element is a cylindrical cell reel.

9. The energy store system as recited in claim 1 , wherein the anode and the cathode are plates situated parallel to one another.

10. The energy store system as recited in claim 1 , wherein the anode, the cathode, and the electrolyte system are situated together in a single housing.

11. The energy store system as recited in claim 1 , wherein the light source and the detector are aligned with the aligned light transmitting regions of the anode and the cathode.

12. A state detection system, comprising:
an energy store system, including:
at least one cell element situated in a cell region, having an anode, a cathode and an electrolyte system, situated between the anode and the cathode, that is at least partially liquid, wherein the anode and the cathode each have a light transmitting region, the light transmitting region of the anode being aligned with the light transmitting region of the cathode;
wherein at least one of the anode, the cathode and the electrolyte system are configured so that, as a function of at least one of a charging process and a discharging process of the cell element, functional material is situated in the electrolyte system, and the functional material situated in the electrolyte system is ascertainable at least one of qualitatively and quantitatively;
a light source by which the electrolyte system is at least partially irradiated through the aligned light transmitting regions of the anode and the cathode; and
a detector by which the absorption of the irradiated electrolyte system is analyzable via light from the light source, wherein the anode and the cathode are situated between the light source and the detector; and
an evaluation unit.
