CHARGING CABLE WITH CHARGING PLUG

Abstract

A charging cable is provided having a charging plug for electrically driven motor vehicles. A method for its operation is also provided.

Claims

1. A charging cable with charging plug for an electrically driven motor vehicle, the charging plug comprising: at least one integrated warning light; and a brightness sensor which is adapted to measure an ambient brightness and to activate the at least one warning light of the charging plug when the measured ambient light falls below a limit value.

2. The charging cable with charging plug according to claim 1, wherein a power supply of the at least one warning light comes via a pole on the charging plug.

3. The charging cable with charging plug according to claim 1, wherein a power supply of the at least one warning light comes via a separate plug connection with the motor vehicle.

4. The charging cable with charging plug according to claim 1, wherein a power supply of the at least one warning light comes from a battery which is located in a battery compartment integrated in the charging plug.

5. The charging cable with charging plug according to claim 1, wherein the charging cable comprises a warning cover sleeve which is movable along an entire length of the charging cable.

6. The charging cable with charging plug according to claim 5, wherein the warning cover sleeve has a variable length.

7. The charging cable with charging plug according to claim 5, wherein the warning cover sleeve comprises a multicolored textile.

8. The charging cable with charging plug according to claim 5, wherein the warning cover sleeve comprises at least two velcro straps with which the warning cover sleeve can be secured in a desired position on the charging cable.

9. A method for charging an electrically driven motor vehicle making use of a charging cable with charging plug including at least one integrated warning light and a brightness sensor which is adapted to measure an ambient brightness and to activate the at least one warning light when the measured ambient light falls below a limit value, the method comprising: activating the at least one warning light when the ambient brightness is less than the limit value.

10. A method for charging an electrically driven motor vehicle making use of a charging cable with charging plug including at least one integrated warning light and a brightness sensor which is adapted to measure an ambient brightness and to activate the at least one warning light when the measured ambient light falls below a limit value, the method comprising: moving a warning cover sleeve of the charging cable to a position of the charging cable where the charging cable constitutes a particularly dangerous place for passers-by, and securing the warning cover sleeve there.

Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0014] Embodiments are illustrated in the accompanying drawings and shall be described further with reference to the drawings.

[0015] FIG. 1 shows a schematic representation of one embodiment of a charging cable with charging plug.

[0016] FIG. 2 shows one embodiment of the warning cover sleeve.

DETAILED DESCRIPTION

[0017] FIG. 1 shows schematically one embodiment of the charging cable 2 with charging plug 1. A warning light 3 is integrated in the charging plug 1. A brightness sensor 5 in the charging plug measures the ambient brightness and activates the warning light 3 upon falling below a given limit value. In the embodiment shown, the power supply of the warning light 3 comes either via a separate plug connection 7 at the charging socket of the vehicle being charged, or via a battery located in the battery compartment 6. A cap 8 movably arranged on the charging plug 1 is intended for protection of the pins of the charging plug 1 when not in use. The charging cable 2 has a warning cover sleeve 4, which can be moved along the entire length of the charging cable 2, as indicated by arrows in the drawing.

[0018] FIG. 2 shows one embodiment of the cylindrical warning cover sleeve 4. This consists of a textile 4a, being arranged in signal colors and optionally being multicolored, at least one wire 4b, running on the periphery of the cylinder of the sleeve and giving it mechanical strength, and velcro straps 4c arranged in proximity to the ends of the sleeve 4, with which the sleeve 4 can be secured in any given position on the charging cable 2. In one embodiment, the wire 4b runs in a spiral on the periphery of the sleeve 4.

[0019] German patent application no. 10 2021 123321.6, filed Sep. 9, 2021, to which this application claims priority, is hereby incorporated herein by reference, in its entirety. Aspects of the various embodiments described above can be combined to provide further embodiments. These and other changes can be made to the embodiments in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
