Abstract
A boat having an electric motor coupled with an electrical store is disclosed. The electrical store includes a storage element, and positive and negative poles in current-conducting connection with the storage element. An isolating circuit element is operatively connected to a user activatable emergency stop switch. The isolating circuit element is configured to, upon activation of the emergency stop switch, isolate the current-conducting connection between the storage element and at least one of the poles.
Claims19
A boat, comprising:
- an electric drive that provides propulsive power to the boat;
- an electrical store configured to couple with the electric drive, the electrical store including:
- a storage element, and
- positive and negative poles in current-conducting connection with the storage element;
- a user activatable emergency stop switch, including a magnet and a magnetic field sensing sensor, the emergency stop switch activating when the sensor senses a magnetic field change caused by the magnet;
- and
- an isolating circuit element operatively connected to the emergency stop switch, and configured to, upon activation of the emergency stop switch, isolate the current-conducting connection between at least one of the poles and the storage element.
A method for isolating an electrical consumer from an electrical store of a boat, the electrical store including a storage element, and positive and negative poles in current-conducting connection with the storage element and the electrical consumer, the method comprising:
- activating an emergency stop switch operatively connected to an isolating circuit element, the emergency stop switch including a magnet and a magnetic field sensing sensor, the emergency stop switch activating when the sensor senses a magnetic field change caused by the magnet;
- and
- isolating, in response to activation of the emergency stop switch, the current-conducting connection between at least one of the poles and the storage element, via the isolating circuit element.
A boat, comprising:
- an electric drive that provides propulsive power to the boat;
- an electric source that powers the electric drive;
- a user activatable emergency stop switch, including a magnet and a magnetic field sensing sensor, the emergency stop switch activating when the sensor senses a magnetic field change caused by the magnet;
- and
- a stopping mechanism operatively connected to the emergency stop switch, and configured to, upon activation of the emergency stop switch, stop operation of the electric drive.
