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.
Claims16
An outboard motor assembly for a boat, the outboard motor assembly comprising:
- an electric motor for propelling the boat;
- a battery coupled to the electric motor, the battery including:
- positive and negative poles in current-conducting connection with a battery cell;
- 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 battery cell.
An emergency stop system for an outboard motor of a boat, comprising:
- a user activatable stop switch, including a user-displaceable magnet positioned on a housing of the outboard motor, and a magnetic field sensing sensor that activates the stop switch upon sensing a magnetic field change caused by displacement of the magnet;
- and
- an isolating circuit element operatively connected to the stop switch, and configured to, upon activation of the stop switch, isolate a current-conducting connection between:
- (a) a cell of a battery of the outboard motor, and (b) at least one electrical pole of the battery, the at least one electrical pole being in the current-conducting connection with the cell.
