Abstract
The present disclosure relates to a charging control method and system for a marine propulsion device, and a marine propulsion device. The method includes: acquiring a rotational speed and a regeneration charging power of a motor during a sailing process of a vessel; adjusting the rotational speed to obtain the regeneration charging power corresponding to the adjusted rotational speed, and searching for a power extreme point of the regeneration charging power relative to the rotational speed based on a regeneration charging power varying process; maintaining the rotational speed corresponding to the power extreme point to realize regeneration charging of a battery.
