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, comprising:

an electrical drive having electrical components and an electrical accumulator, the electrical components being connected to one another via an electrical wiring system, wherein the electrical components comprise an electric motor;

a first connecting device having main contacts connecting at least one of the electrical components to the wiring system; and

a second connecting device connecting the electrical accumulator to the wiring system and configured to disconnect the electrical accumulator from the wiring system,

wherein the first connecting device further includes auxiliary contacts connecting the at least one electrical component to a monitoring line operatively connected to the second connecting device.

2. The boat of claim 1, wherein the first connecting device is in the form of a plug-in connection.

3. The boat of claim 1, wherein the auxiliary contacts lag the main contacts.

4. The boat of claim 1, wherein the electrical accumulator is a battery.

5. The boat of claim 1, wherein the electrical accumulator is a voltage source having a terminal voltage of more than 60 V.

6. The boat of claim 1, wherein a plurality of the electrical components are connected to the monitoring line, and wherein the main contacts are connected in parallel with one another.

7. The boat of claim 1, wherein a plurality of the electrical components are connected to the monitoring line, and wherein the auxiliary contacts are connected in series with one another.

8. The boat of claim 1, wherein the electrical components comprises a component controller, and power is supplied to the component controller via the monitoring line.

9. The boat of claim 1, wherein a voltage source is connected to the monitoring line.

10. The boat of claim 1, wherein a current source is connected to the monitoring line.

11. The boat of claim 1, wherein the monitoring line is operatively connected to the second connecting device by means of a relay.

12. The boat of claim 1, wherein the electrical components comprise a fault detection unit connected to the monitoring line.

13. A sequential method for connecting an electrical component to an electrical wiring system, including at least one electrical accumulator, of a boat, the sequential method comprising:

disconnecting the electrical accumulator from the wiring system;

connecting the electrical component to the wiring system

connecting the electrical component to a monitoring line; and

connecting the electrical accumulator to the wiring system.

14. A sequential method for disconnecting an electrical component from an electrical wiring system, including at least one electrical accumulator, of a boat, wherein the electrical component is initially connected to the wiring system and to a monitoring line, the sequential method comprising:

disconnecting the electrical component from the monitoring line;

subsequently disconnecting the electrical accumulator from the wiring system; and

disconnecting the electrical component from the wiring system.
