To provide a marine propulsion device that can achieve excellent power generation efficiency, a ship equipped with the same, and a power supply system.SOLUTION: A power supply system of an outboard motor includes: a generator 62 driven by an engine; a rectifier regulator 70 connected to the generator; and a charging control unit 80 that controls charging of the battery 90 with the power generated by the rectifier regulator. The charging control unit operates such that the induced voltage of the generator approaches one-half of the voltage across the battery's terminals. The battery may include a first battery 91 and a second battery 92 different in voltage across the battery's terminals. The charging control unit includes: a switching unit 83 that connects the rectifier regulator to either the first battery or the second battery; and a controller 86 that controls the switching unit according to the engine rotation speed detected by an engine rotation speed sensor 59.SELECTED DRAWING: Figure 3

    【課題】優れた発電効率を実現できる船舶推進機およびそれを備えた船舶、ならびに電源システムを提供する。【解決手段】船外機の電源システムは、エンジンによって駆動される発電機62と、発電機に接続されたレクチファイアレギュレータ70と、レクチファイアレギュレータが生成する電力によるバッテリ90の充電を制御する充電制御ユニット80と、を含む。充電制御ユニットは、発電機の誘起電圧がバッテリの端子間電圧の2分の1に近づくように作動する。バッテリは、端子間電圧が異なる第1バッテリ91および第2バッテリ92を含んでもよい。充電制御ユニットは、レクチファイアレギュレータを第1バッテリおよび第2バッテリのいずれかに接続する切替ユニット83と、エンジン回転速度センサ59が検出するエンジン回転速度に応じて切替ユニットを制御するコントローラ86と、を含んでもよい。【選択図】図3
