The invention discloses a multi-power-supply ship direct-current electric propulsion system and a working method thereof. The multi-power-supply ship direct-current electric propulsion system comprises a power supply module, an electric propulsion device, a charging device, a direct-current bus, an energy conversion device, a direct-current power distribution device and an energy management module. The power supply module comprises a fuel battery pack, a lithium battery pack, a super capacitor, a solar photovoltaic power generation assembly and a wind power generation device. The energy management module collects information through the DC power distribution device. The system is used for reasonably distributing energy output of a fuel battery pack, a lithium battery pack, a super capacitor, a solar photovoltaic power generation assembly and a wind power generation assembly. The fuel cell and composite energy storage system has the advantages of high integration level, low equipment cost, small occupied area and light weight, and can flexibly distribute power output of the fuel cell and the composite energy storage module to provide enough energy output for the load when the load changes. And the energy management module is adopted, so that the fuel cell and the composite energy storage device can output more efficiently, and the energy use efficiency of the whole system can be remarkably improved.

    本发明公开了一种多电源动力的船舶直流电力推进系统及其工作方法,包括供电模块、电力推进装置、充电装置、直流母线、能量转换装置、直流配电装置和能量管理模块。所述供电模块包括燃料电池组、锂电池组、超级电容、太阳能光伏发电组件、风力发电装置。能量管理模块通过直流配电装置采集信息;用于合理分配燃料电池组、锂电池组、超级电容、太阳能光伏发电组件、风力发电组的能量输出。具有较高的集成度,较低的设备成本,占地面积小及重量低,当负载发生变化时,可以灵活地分配燃料电池和复合储能模块的功率输出,为负载提供足够的能量输出。采用能量管理模块,使燃料电池和复合储能装置更高效率输出,可显著提高整个系统的能源使用效率。
