To provide a battery-mounted type electric propulsion vessel system with high energy saving effect capable of most efficiently controlling driving of a power generation motor and supply of power according to a residual amount in a storage battery and a navigation state.SOLUTION: A battery-mounted type electric propulsion vessel system includes a main engine which is a propulsion motor, a storage battery, a power generation motor, and propulsion means for propelling a hull, and is configured to: (i) when a residual amount in the storage battery becomes small, generate, by the power generation motor, power to supply the power to the storage battery until the residual amount of the storage battery becomes almost full, as well as, to optionally supply the power to a main engine and/or an inboard load; (ii) after the residual amount of the storage battery is almost full, stop the power generation motor until the amount becomes small again, and supply, by the storage battery, power to the main engine and/or the inboard load; and after that, repeat these operations.SELECTED DRAWING: Figure 1
【課題】蓄電池の残量や運航状況に応じて、発電原動機の運転と電力の供給を最も効率良く行なえるように制御できる省エネ効果の高い電池搭載型電気推進船舶システムを提供する。【解決手段】推進電動機である主機関と、蓄電池と、発電原動機と、船体を推進するための推進手段とを含む、電池搭載型電気推進船舶システムであって、(i)蓄電池の残量が少なくなった場合、発電原動機は、蓄電池の残量がほぼ満杯になるまで発電を行なって蓄電池に電力を供給するとともに任意選択的に主機関及び/又は船内負荷に電力を供給し、(ii)蓄電池の残量がほぼ満杯に到達した後は再び少なくなるまで発電原動機は、停止され、蓄電池が主機関及び/又は船内負荷に電力を供給し、その後はこれらの動作を繰り返す。【選択図】図1
