[0005] One aspect of the present invention relates to a method for indicating a charging level of an electric storage device of an at least partially electrically operated motor vehicle by a charging indication device of the motor vehicle. A charging of the electric storage device may be detected by a detection device of the charging indication device. A level of charging of the electric storage device may also be detected by a battery management system of the electric storage device. A charging level signal for a light device of the motor vehicle may be generated depending on the detected charging level by an electronic computing device of the charging indication device, and the charging level signal may be displayed on the light device, wherein the light device may be configured as a necessary light device for a driving operation of the motor vehicle.
[0006] Therefore, multiple display outputs are possible on the motor vehicle, while utilizing the existing lighting hardware optimally. The desirable indicator may be made active by virtue of, for example, the vehicle orientation. Furthermore, a camera may detect a person in the vicinity of the motor vehicle. For example, a person may be detected in the front of the motor vehicle, and the charging level signal may be provided using a front illumination when the display hardware on the motor vehicle front is activated. In some embodiments, the charging level signal may be provided using a back illumination device that may be activated on the rear side of the motor vehicle. In other embodiments, the charging level signal may be provided using another comparable illumination device on the motor vehicle.

This embodiment is described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
[0029] Fig. 1 shows a schematic side view according to the embodiment of motor vehicle 10. The motor vehicle 10 is at least partially electrically operated or fully electrically operated. Therefore, the motor vehicle 10 includes at least one electric storage device 12. The motor vehicle 10 includes at least one charging indication device 14 for indicating a charging level of the electric storage device 12. Therefore, the charging indication device 14 includes at least one detection device 16 and one electronic computing device 18.
[0030] According to Fig. 1, the motor vehicle 10 may be connected to a charging station 20 via an electric or cable connection 22, wherein a plug 24 of the charging station 20 is plugged in a corresponding socket 26 for the plug 24.
[0031] According to an embodiment of the present invention the charging of the electric storage device 12 may be detected by the detection device 16 and a level of charging of the electric storage device 12 may be detected by a battery management system 28 of the electric storage device 12. The battery management system 28 may be wired to the electronic computing device 18. The electronic computing device 18 may generate a charging level signal 30 for a light device 32, 34, 36, 38 of the motor vehicle 10 based on the detected charging level, and at least one light device 32, 34, 36, 38 may display the charging level signal 30 wherein the light device 32, 34, 36, 38 is configured for a driving operation of the motor vehicle 10 such as the necessary light device 32, 34, 36, 38.
[0032] In particular, the light device 32, 34, 36, 38 is configured as head lights 32 of the motor vehicle 10 and/or back lights 36, 38 of the motor vehicle 10 and/or safety light 34 in a mirror of the motor vehicle 10. In some embodiments, the light device 34, 38 may be include a windshield.
[0033] Furthermore, Fig. 1 shows that the charging level signal may be generated if a person 40 is in a vicinity 42 of the motor vehicle 10 is detected by the charging indication device 14, wherein, for example, therefore the charging indication device 14 includes a camera 44 and/or another comparable sensor.
[0034] In particular Fig. 1 shows, that the charging level which may also be called the "state of charge" (SOC) that may be indicated as a progressing status by an array of the light devices 32, 34, 36, 38, in particular in embedded LED lamps. The charging indication device 14 may also display the charging process through multi-color-schemes, and may also show symbols such as arrows in case of unsuccessful connection or charging process. Furthermore, the charging indication device 14 may show a warning symbol in case of unexpected drop of charging. Furthermore, the charging level may also be projected by the light device 32, 34, 36, 38.
[0035] The charging indication device 14 may be implemented as a part of the side-view mirror projection device. The charging indication device 14 may project the progress of charging in the form of a progressing status bar. For example, the charging indication device 14 may control the side-view mirror projection device to project the charging status and/or a warning related to the charging process. Furthermore, the charging indication device 14 may be implemented within the windshield by using a smart windshield technology and/or a head up display.
[0036] According to another embodiment, the charging indication device 14 may be implemented within the interior ambient lighting system. For example, the light device 38 may include the interior ambient lighting system. The interior ambient lighting system may display a light green illumination that may indicate low state-of-charge levels, and/or a dark green illumination may indicate high state-of-charge levels. Once charging is completed, the interior light may turns off or another color as defined in the charging indication device 14. Any connection errors may be indicated by for example a yellow light.
S
[0037] The charging indication device 14 may also indicate the charging status such as the charging level signal 30 using a manufacturer (OEM) logo. The illuminated logo on the front and back of the motor vehicle 10 may be illuminated different patterns and/or colors showing the state of charge. For example, blinking and/or a light green color may indicate a low state-of-charge or the progress of charging. When the charging is in progress, the state of charge may be indicated as a progress bar on the circumference of the logo. An active charging process may be indicated by slowly blinking LEDs. In case of an error, the illuminated logo may turn into a fast blinking yellow light.
[0038] The charging indication device 14 may also be integrated around the circumference of the license plate of the motor vehicle 10, which also displays a blinking status bar to demonstrate the state of charging and progress of charging.
