The embodiment of the invention discloses a marine energy storage system and a charging method thereof. The charging method of the marine energy storage system comprises the following steps: receiving a charging instruction for charging the marine energy storage system; obtaining the branch voltage of each power supply branch; determining a power-on strategy of the power supply branch according to the branch voltage, and closing a charging switch in the second high-voltage box according to the power-on strategy so as to power on the power supply branch; and if all the power supply branches are electrified, a charging switch in the first high-voltage box is closed, so that the battery pack in each power supply branch is charged through the first high-voltage box, the voltage consistency of each power supply branch in the charging stage can be ensured, and the problem that the power supply branches cannot be charged after the marine energy storage system is charged is avoided. Therefore, the problem that the consistency of the voltage between the power supply branches is poor is solved, and the reliability and the safety of the marine energy storage system are greatly improved.

    本申请实施例公开了一种船用储能系统及其充电方法。船用储能系统的充电方法包括:接收对船用储能系统进行充电的充电指令;获取每条供电支路的支路电压;根据支路电压确定供电支路的上电策略,并根据上电策略闭合第二高压箱中的充电开关,以对供电支路进行上电;若所有的供电支路上电完成,闭合第一高压箱中的充电开关,以通过第一高压箱对每条供电支路中的电池包进行充电,进而可以确保各供电支路充电阶段的电压一致性,避免了船用储能系统在完成充电后,各供电支路之间的电压的一致性较差的问题,极大的提高了船用储能系统的可靠性和安全性。
