- the Bragg grating 20 consists of a periodic series of disk-shaped regions which are arranged in the core of the optical waveguide 22 and which have a refractive index ni deviating from the normal refractive index n 2 of the core of the optical waveguide.
- ni refractive index
- Deformation of the optical waveguide 22 in the region of a Bragg grating 20, for example due to a change in temperature or deformation of the cell leads to a local length expansion or contraction and thus to a change in the grating period, resulting in a shift of the spectral intensity distribution of the backscattered light Has.

A small portion of the light is then scattered back at the Bragg gratings 20, with a spectral intensity distribution characteristic of the respective grating, which depends on the grating period of the grating.
- Different gratings and thus different battery units can consequently be identified by means of different wavelengths of the backscattered light.
- the wavelength of the backscattered light is greater, the greater the grating period.
- a pulsed, monochromatic light source is preferably used to measure the physical parameter. Different gratings and thus different battery units can consequently be identified by different transit times of the light pulses.

- a reference quantity e.g. the ambient temperature or vibrations of the housing
- an expected profile 45 of the battery 6 measured and derived therefrom by the control device 35 an expected profile 45 of the battery 6, as shown by way of example in FIG.
- the derivation of the expected profile 45 from the measured value of the reference variable can be carried out either on the basis of previously (eg mathematically and / or experimentally) determined profiles stored in the control device 35, which profiles are respectively assigned to different measured values of the reference variable, or based on a current calculation, which, for example, can also take place with the help of a neural network.
- the current profile 40 is compared in the control device 35 with the expected profile 45 and controlled by the controller 35, the operation of the battery in response to a deviation from the expected profile 45 and / or regulated.
- the profiles 40, 45 shown in FIGS. 12 and 13 represent, for example, the temperature of the cells
- the current profile 40 still has another maximum in the lower right area 43 of the battery, which is an indication of insufficient cooling or the onset of malfunction of the cells 12 in this area 43.
- an additional cooling device 37 for the battery 6 can now be activated in a first step via a control line 39.
- the control device 35 via Kom- the module management devices 19 of the battery modules 11 concerned, the comparatively abnormal operating state are signaled so that the module management devices 19 can initiate targeted countermeasures.
- the control device 35 at least partially shuts off the battery (for example by opening a battery switch).
- a second embodiment of a device 30 shown in FIG. 11 differs from the device 30 shown in FIG. 10 in that the measuring arrangement 31 has a light source 32 common to all optical waveguides 22 and a common signal processing device 34 instead of its own light source 32 and signal processing device 34, respectively each of the optical waveguides 22 has.
- the directional couplers 33 are connected in series via optical waveguides 36A, 36B and couple light emitted by the light source 32 into the optical waveguides 22 and light scattered back to the signal processing device 34.
- the directional couplers 33 are designed such that they only couple out light of a specific wavelength range (referred to below as “coupling-out region") and transmit light outside this wavelength range 10 is thus associated with exactly one of these coupling-out regions, ie, light is coupled out of the wavelength range assigned to the optical waveguide 22 connected to it, but light is passed on in coupling regions of the other optical waveguides 22. Only one of the directional couplers 33 is directly connected to the common light source 32 and the common signal processing device 34.
- the number of battery strings 10 that can be monitored thereby is essentially only the bandwidth that must be provided per Bragg grating for the spectral separation of the signals scattered back from the individual Bragg gratings, the required width of the outcoupling regions and the bandwidth of the Limited light source.
