[0043] A preferred embodiment of the subject matter of the invention is illustrated in the drawings and is explained in more detail below. Fig. 1 a perspective view of a mobile energy storage unit according to the invention, Fig. 2 a perspective view of the mobile energy storage unit according to the invention, standing upside down, according to Fig. 1, Fig. 3 a perspective interior view of the mobile energy storage unit according to the invention, according to Fig. 1, Fig. 4 a schematic cross-sectional view of the upper part of the mobile energy storage unit according to the invention, according to Fig. 1, and Fig. 5 a further schematic cross-sectional view of the upper part of the mobile energy storage unit according to the invention, according to Fig. 1. Description of the embodiments

[0044] Fig. 1 shows a perspective view of a mobile energy storage unit 1 according to the invention. The energy storage unit 1 according to the invention has a top side 2, a bottom side 3, and an outer side 4. The top side 2 consists of a cover 5 and a rotatable cover 6, beneath which the connections 7 for terminal devices are arranged. The cover 5 has a display 8 and a button 9 for switching the display 8 on and off. A carrying handle 11 is attached to the mobile energy storage unit 1 according to the invention by means of a loop rivet 10. Between an outer edge 12 of the cover 5 and other housing parts there is an opening 13, through which a collecting channel, accessible from the top, can be reached. This collecting channel serves to collect liquid that has entered the mobile energy storage unit 1.

[0045] Fig. 2 shows a perspective view of the mobile energy storage unit 1 according to the invention, standing upside down, according to Fig. 1. The mobile energy storage unit 1 according to the invention has openings 14 through which colder air can be drawn in, which are accessible from the underside 3 of the mobile energy storage unit 1 according to the invention. The mobile energy storage unit 1 according to the invention also has a main switch 15 with which the mobile energy storage unit 1 according to the invention can be switched on and off.

[0046] Fig. 3 shows a perspective interior view of the mobile energy storage unit 1 according to the invention, according to Fig. 1. Channels 16 extend from the top side 2 of the mobile energy storage unit 1 according to the invention to the bottom side 3, through which liquid can be drained. The channels 16 are connected to the collecting channel, which is accessible from the top side 2 via the opening 13.

[0047] Fig. 4 shows a schematic cross-sectional view of the upper part of the mobile energy storage unit 1 according to the invention, according to Fig. 1. A collecting trough 17 is arranged such that it is accessible from the top side 2 of the mobile energy storage unit 1 according to the invention via the opening 13. The collecting trough 17 is connected to at least one channel 16, so that liquid that penetrates into the interior of the mobile energy storage unit via the opening 13 can be guided via the collecting trough 17 to the channel 16, via which it can then be drained to the bottom side 3 of the mobile energy storage unit 1 according to the invention and from there to the outside.

[0048] Fig. 5 shows a further schematic cross-sectional view of the upper part of the mobile energy storage unit 1 according to the invention, according to Fig.1. A carrying handle 11 is attached to the mobile energy storage unit 1 according to the invention by means of a two-part, covered loop rivet 10. The cover 5 shields openings 18 through which air can escape from an area in which, for example, electronic and / or battery modules are located. On the outer edge of the cover 12, the opening 13 is arranged, through which the air can flow out from the interior of the mobile energy storage unit 1 according to the invention and liquid can penetrate, wherein the liquid is then drained via the collecting channel 17 to at least one channel 16. The outflowing air and the penetrating liquid thus have a common flow path, at least in the region of the opening 13. The opening 13 and the openings 18 are directed upwards, which allows very good heat transport out of the interior of the mobile energy storage unit 1.This heat transfer can be supported by a fan, which also offers the possibility of preventing liquid from penetrating the interior of the mobile energy storage unit and / or the area containing electronic and / or battery modules by increasing the airflow, thus providing additional protection for the electronics. The increase in airflow can be controlled by a sensor, which, for example, measures the humidity in the form of a humidity sensor, the temperature in the form of a temperature sensor, or the liquid level in the form of a water level sensor, and adjusts the fan's power, drying rate, and / or running time accordingly.Furthermore, additional openings would be conceivable, which can be opened automatically depending on the sensors in order to drain additional liquid to the outside or that the openings 18 and / or the opening 13 are closed if too much liquid enters.
