Abstract

A high-voltage apparatus has at least one high-voltage component and at least one current sensor, which is assigned to a corresponding high-voltage component. The high-voltage apparatus has at least one transmission apparatus, to which at least one corresponding current sensor is assigned. The at least one transmission apparatus is designed to provide an information signal, which contains information on whether there is a potential risk originating from the corresponding high-voltage component or not, depending on a measurement signal of the at least one corresponding current sensor, by way of a wireless radio link in order for the information to be reproduced on an external reproduction apparatus.

Claims

1. A high-voltage apparatus, comprising:

a plurality of high-voltage components, each high-voltage component having an associated current sensor and transmission apparatus,

wherein the transmission apparatus receives a measurement signal from the associated current sensor and based thereon transmits an information signal, which includes threat data indicating a threat status of an associated high-voltage component and position data indicating a position of the associated current sensor, via a wireless radio link to an external reproduction apparatus, so as to cause the external reproduction apparatus to display thereon (i) the position of the associated current sensor within the high-voltage apparatus, and (ii) the threat status of the associated high-voltage component.

2. The high-voltage apparatus according to claim 1, wherein the high-voltage apparatus is a vehicle.

3. The high-voltage apparatus according to claim 2, wherein the information signal contains a vehicle identifier representative of a vehicle type of the vehicle.

4. An external reproduction apparatus, comprising:

a radio reception unit configured to receive an information signal provided by a high-voltage apparatus having a plurality of high-voltage components, each high-voltage component having an associated current sensor, the information signal including threat data indicating a threat status of an associated high-voltage component and position data indicating a position of the associated current sensor; and

a display configured to display, based on the information signal, (i) the position of the associated current sensor within the high-voltage apparatus, and (ii) the threat status of the associated high-voltage component as a respective two-colored set of traffic lights, wherein a first traffic light color represents no threat being posed by the associated high-voltage component and a second traffic light color represents a threat being posed by the associated high-voltage component.

5. The external reproduction apparatus according to claim 4, wherein

wherein the display is further configured to display the respective two-colored set of traffic lights so as to indicate the position of the current sensor within the high-voltage apparatus.

6. The external reproduction apparatus according to claim 5, wherein

the high-voltage apparatus is a vehicle,

the information signal contains a vehicle identifier representative of a vehicle type of the vehicle,

the external reproduction apparatus is configured to display the respective two-color set of traffic lights at the position indicative of the position of the respective current sensor on a vehicle depiction matching the vehicle type of the vehicle.

7. A system, comprising:

a high-voltage apparatus, the high-voltage apparatus comprising;

a plurality of high-voltage components, each high-voltage component having an associated current sensor and transmission apparatus, wherein the transmission apparatus receives a measurement signal from the associated current sensor and based thereon transmits an information signal, which includes threat data indicating a threat status of an associated high-voltage component and position data indicating a position of the associated current sensor, via a wireless communication link;

an external reproduction apparatus, the external reproduction apparatus comprising;

a wireless reception unit configured to receive the information signal provided by the high-voltage apparatus;

a display configured to display, based on the received information signal, (i) the position of the associated current sensor within the high-voltage apparatus, and (ii) the threat status of the associated high-voltage component as a respective two-colored set of traffic lights, wherein a first traffic light color represents no threat being posed by the associated high-voltage component and a second traffic light color represents a threat being posed by the associated high-voltage component.
