Abstract

The invention relates to a boat with an electric drive that comprises electric components, especially an electric motor and an electric storage unit. The components are interconnected via an electric grid. At least one of the components is connected to the grid by means of a first connection means, the first connection means comprising first connection means main contacts for connecting the at least one component to the grid, and a second connection means being provided for connecting the electric storage unit to or disconnecting it from the grid. According to the invention, the first connection means comprises at least one pair of auxiliary contacts for connecting the at least one component to a monitoring line and said monitoring line is operatively connected to the second connection means.

Claims

1. A boat having an electrical drive, which comprises electrical components, in particular an electric motor and an electrical accumulator (1), which components (2, 102) are connected to one another via an electrical wiring system, wherein at least one of the components (2, 102) is connected to the wiring system by means of a first connecting device (7, 107), which first connecting device (7, 107) has main contacts (3, 4, 5, 6, 103, 104, 105, 106) for connecting the at least one component (2, 102) to the wiring system, and wherein a second connecting device (10, 11) is provided in order to connect the electrical accumulator (1) to the wiring system or to disconnect same from the wiring system, characterized in that the first connecting device (7, 107) comprises at least one pair of auxiliary contacts (15, 16, 17, 18, 115, 116, 117, 118) for connecting the at least one component (2, 102) to a monitoring line (12), and in that the monitoring line (12) is operatively connected to the second connecting device (10, 11).

2. The boat as claimed in claim 1, characterized in that the first connecting device (7, 107) is in the form of a plug-in connection.

3. The boat as claimed in claim 1 or 2, characterized in that the auxiliary contacts (15, 16, 17, 18, 115, 116, 117, 118) lag the main contacts (3, 4, 5, 6, 103, 104, 105, 106).

4. The boat as claimed in any of the previous claims, characterized in that the electrical accumulator (1) is in the form of a voltage source, particularly in the form of a non-rechargeable or rechargeable battery.

5. The boat as claimed in any of the previous claims, characterized in that the electrical accumulator (1) is in the form of a voltage source having a terminal voltage of more than 60 V.

6. The boat as claimed in any of the previous claims, characterized in that a plurality of components (2, 102) are connected to the monitoring line (12), wherein the main contacts (3, 4, 5, 6, 103, 104, 105, 106) of the components (2, 102) are connected in parallel with one another.

7. The boat as claimed in any of the previous claims, characterized in that a plurality of components (2, 102) are connected to the monitoring line (12), wherein the auxiliary contacts (15, 16, 17, 18, 115, 116, 117, 118) of the components (2, 102) are connected in series with one another.

8. The boat as claimed in any of the previous claims, characterized in that the at least one component (2, 102) comprises a component controller, and in that the power is supplied to the component controller via the monitoring line (12).

9. The boat as claimed in any of the preceding claims, characterized in that a voltage source is connected to the monitoring line.

10. The boat as claimed in any of the preceding claims, characterized in that a current source is connected to the monitoring line.

11. The boat as claimed in any of the previous claims, characterized in that the monitoring line (12) is operatively connected to the second connecting device (10, 11) by means of a relay.

12. The boat as claimed in any of the preceding claims, characterized in that the component comprises a fault detection unit, which is connected to the monitoring line.

13. A method for connecting an electrical component (2, 102) to an electrical wiring system comprising at least one electrical accumulator (1) and located on a boat, characterized in that the electrical accumulator (1) is disconnected from the wiring system, the component (2, 102) is subsequently connected to the wiring system, and then the component (2, 102) is connected to a monitoring line (12), and the electrical accumulator (1) is not connected to the wiring system until the component (2, 102) is connected to the monitoring line (12).

14. A method for disconnecting an electrical component (2, 102) from an electrical wiring system comprising at least one electrical accumulator (1) and located on a boat, characterized in that initially the component (2, 102) is in the condition in which it is connected to the wiring system and to a monitoring line (12), then the component (2, 102) is disconnected from the monitoring line (12), whereupon the electrical accumulator (1) is disconnected from the wiring system and then the component (2, 102) is disconnected from the wiring system.
