Abstract
A battery diagnostic device for an electric propulsion machine. The battery diagnostic device is configured to diagnose a battery configured to supply electric power to a motor for driving a propeller of the electric propulsion machine. The battery diagnostic device includes a controller configured to perform a battery diagnosis process of diagnosing the battery by discharging from the battery to the motor, in a state where a boat to which the electric propulsion machine is attached is moored, determine whether the boat has moved, and stop discharging from the battery to the motor for diagnosing the battery, in a case where the controller determines that the boat has moved during the battery diagnosis process.
Claims7
A battery diagnostic device for an electric propulsion machine, the battery diagnostic device being configured to diagnose a battery configured to supply electric power to a motor for driving a propeller of the electric propulsion machine, the battery diagnostic device comprising:
- a controller configured to:
- perform a battery diagnosis process of diagnosing the battery by discharging from the battery to the motor, in a state where a boat to which the electric propulsion machine is attached is moored;
- determine whether the boat has moved;
- and
- stop discharging from the battery to the motor for diagnosing the battery, in a case where the controller determines that the boat has moved during the battery diagnosis process.
A ship propulsion system for propelling a boat, the ship propulsion system comprising:
- an electric propulsion machine that is attached to the boat and that includes a motor for driving a propeller;
- a battery configured to supply electric power to the motor;
- and
- a battery diagnostic device for the electric propulsion machine configured to diagnoses the battery,
- wherein the battery diagnostic device includes a controller configured to:
- perform a battery diagnosis process of diagnosing the battery by discharging from the battery to the motor while the boat is moored;
- determine whether the boat has moved;
- and
- stop discharging from the battery to the motor for diagnosing the battery, in a case where the controller determines that the boat has moved during the battery diagnosis process.
