The invention discloses a lithium battery shore power charging control method based on an oil-electricity dual-drive ship, and the method comprises the steps: obtaining the charge state of a lithium battery pack after a shore power supply is connected to a ship power system, and judging whether the charge state meets a charging condition or not; if the charging condition is met, controlling the input of the ship power system to be transferred from the lithium battery pack to the shore power supply; wherein the lithium battery pack and the shore power supply are connected to a ship power system through a direct current bus; after power transfer is completed, a chopping charging function is started, and the lithium battery pack is started to enter a charging state; and after charging of the lithium battery pack is completed, charging is stopped, and the ship is in a full-electric-quantity berthing state. A plurality of power inputs are connected to a ship power system through a direct-current bus, a power transfer technology is combined, a power supply object of the ship power system is transferred from a lithium battery pack to shore power, after the lithium battery pack stops supplying power, the lithium battery pack is switched from a discharging state to a charging state, and the shore power charges the lithium battery pack through the direct-current bus.

    本发明公开了一种基于油电双驱动船舶的锂电池岸电充电控制方法,包括:在岸电电源接入船舶动力系统后,获取锂电池组的荷电状态,判断是否符合充电条件;若符合所述充电条件,则控制所述船舶动力系统的输入由所述锂电池组向所述岸电电源转移;其中,锂电池组和岸电电源均通过直流母线接入船舶动力系统;在完成功率转移后,启动斩波充电功能并启动所述锂电池组进入充电状态;在所述锂电池组完成充电后,停止充电,使船舶处于满电量停泊状态。多个电源输入均通过直流母线对船舶动力系统,结合功率转移技术,将船舶动力系统的供电对象从锂电池组转移至岸电,锂电池组停止供电后,从放电状态切换为充电状态,由岸电经直流母线对其进行充电。
