[0057] Depending on the information and / or the additional information, a forecast is determined for at least part of the device unit state, in particular by means of the control unit 26a. In particular, a forecast is determined for at least one device and / or device accessory characteristic of the one device 10a and / or the device accessories 14a, 36a. For example, a capacity state of the device accessory 14a configured as an energy storage device is forecast.

[0058] In one method step, in particular in an output step 50a, the device unit status is output, preferably readable by an operator, via an output unit 52a of the mobile terminal 20a and / or transmitted to a separate unit, for example, a central computer, a cloud, or the like. The output unit 52a of the mobile terminal 20a here has, for example, a screen for outputting the device unit status.

[0059] It is also conceivable that the device unit status includes information on product additions, services or the like suitable for the device unit 16a, which are output in particular via the output unit 52a, preferably in the output step 50a.

[0060] Additionally, it is conceivable that, depending on the device unit status, in particular depending on the forecast, a recommendation for proactive maintenance of the device unit 16a is issued, preferably in output step 50a. In particular, it is conceivable that quality forecasts and / or customer satisfaction can be determined based on the device unit status, in particular by means of the control unit 26a.

[0061] For example, in an alternative system with a device designed as an e-bike and a device accessory designed as an energy storage device, in particular as a battery pack, the device unit state could be determined by an operator using the sensor unit 18a of the mobile terminal 20a in order to, for example, book a service, preferably automatically, depending on the device unit state, for example the provision of a replacement battery pack or the like.

[0062] Furthermore, in an alternative system with a device configured as a washing machine, for example, the device unit could be identified by the operator using the sensor unit 18a of the mobile terminal 20a, and the device unit status could be determined, preferably to provide the device unit status to a service employee. The service employee can evaluate the device unit status and / or an automatic ordering of required spare parts can be carried out. Furthermore, it is also conceivable that the method could be applied in industrial engineering, the automotive industry, thermal engineering, or the like.

The following descriptions and the drawings are essentially limited to the differences between the embodiments, whereby with regard to components with the same designation, in particular with regard to components with the same reference numerals, reference is also made to the drawings and / or the description of the other embodiments, in particular to the Fig. 1 and Fig. 2. To distinguish the embodiments, the letter a is added to the reference numerals of the embodiment in the Fig. 1 and Fig. 2. In the examples of the Fig. 3 and Fig. 4, the letter a is replaced by the letters b and c.

[0064] Fig. Figure 3 shows a system 24b with a mobile terminal 20b and a device unit 16b. The device unit 16b here comprises, for example, a device 10b and a device accessory 14b. The device accessory 14b is designed as an energy storage device, in particular as a battery pack. The device 10b is designed as a charger, in particular for the device accessory 14b designed as an energy storage device.

[0065] The device 10b has a device device 22b for outputting information, depending on which, in particular, a device unit status can be determined. The device device 22b has an output unit 28b for optically outputting the information. The output unit 28b is formed by an output unit 30b of the device 10b for displaying a device and / or device accessory characteristic. The output unit 30b is a charge level indicator.

[0066] Fig.4 shows a system 24c with a mobile terminal 20c and a device unit 16c. The device unit 16c here comprises, for example, three devices 10c, 12c, 48c and a plurality of device accessories 14c. The device accessories 14c are designed differently. The device unit 16c here comprises, for example, device accessories 14c designed as a tool case, a circular saw blade, an energy storage device, in particular as battery packs, an extraction nozzle, and a guide rail. One device 10c is designed as a jigsaw. Another device 12c is designed as a circular saw. An additional device 48c is designed as a charger.
