Abstract
In a control device for a battery of a marine vessel, a first value indicating either a voltage or a power storage amount of a main battery to supply electric power to start the engine is acquired. When the first value that has been acquired is smaller than a first threshold value, at least one of a prohibition of a transition to a motor drive mode in which a propeller is driven by using at least a motor regardless of an operation mode that is designated and a prohibition of charging a load battery is performed, and the engine is caused to rotate to charge the main battery.
Claims20
A control device for a battery of a marine vessel, the control device being configured or programmed to control a plurality of batteries mounted on the marine vessel, the marine vessel including a plurality of marine propulsion devices each including only one of an engine and a motor, a propeller of each marine propulsion device is driven by one of the engine and the motor, the plurality of batteries include a main battery to supply electric power to start the engine, a drive battery to supply the electric power to drive the motor, and a load battery to supply the electric power to a load on the marine vessel, and the plurality of batteries are chargeable by a generator, the control device comprising:
- a controller configured or programmed to:
- acquire a first value indicating either a voltage or a power storage amount of the main battery;
- and
- when the first value that has been acquired is smaller than a first threshold value, perform at least one of (i) a prohibition of a transition to a motor drive mode in which the propeller is driven by using at least the motor regardless of an operation mode that is designated, and (ii) a prohibition of charging the load battery, and cause the engine to rotate to charge the main battery.
A control method for a battery of a marine vessel, the control method controlling a plurality of batteries mounted on the marine vessel, the marine vessel including a plurality of marine propulsion devices each including only one of an engine and a motor, a propeller of each marine propulsion device is driven by one of the engine and the motor, the plurality of batteries include a main battery to supply electric power to start the engine, a drive battery to supply the electric power to drive the motor, and a load battery to supply the electric power to a load on the marine vessel, and the plurality of batteries are chargeable by a generator, the control method comprising:
- when a first value indicating either a voltage or a power storage amount of the main battery is smaller than a first threshold value, performing at least one of (i)a prohibition of a transition to a motor drive mode in which the propeller is driven by using at least the motor regardless of an operation mode that is designated, and (ii) a prohibition of charging the load battery;
- and
- causing the engine to rotate to charge the main battery.
A marine vessel comprising:
- a control device;
- a plurality of marine propulsion devices each including only one of an engine and a motor, and a propeller that is driven by one of the engine and the motor;
- and
- a plurality of batteries including a main battery to supply electric power to start the engine, a drive battery to supply the electric power to drive the motor, and a load battery to supply the electric power to a load on the marine vessel, the plurality of batteries being chargeable by a generator;
- wherein
- the control device includes a controller configured or programmed to:
- acquire a first value indicating either a voltage or a power storage amount of the main battery;
- and
- when the first value that has been acquired is smaller than a first threshold value, perform at least one of (i) a prohibition of a transition to a motor drive mode in which the propeller is driven by using at least the motor regardless of an operation mode that is designated, and (ii) a prohibition of charging the load battery, and cause the engine to rotate to charge the main battery.
