The embodiment of the invention provides a ship battery replacement method and a ship high-voltage system, and relates to the technical field of ship battery replacement. The ship battery replacement method comprises the following steps: receiving electric quantity information of a currently accessed battery pack sent by a battery management system; when the electric quantity of the currently accessed battery pack is smaller than a first set value and the battery replacement mode is feasible, sending a motor power reduction instruction to the DC-AC controller; and executing packet change control logic according to the motor power reduction progress information sent by the DC-AC controller. According to the invention, the power of the motor is reduced instead of replacing the power after the motor of the ship is stopped, so that the package replacement is carried out when the power of the motor is reduced to be within a safe range, and compared with a mode of replacing the package after the motor is stopped, the power loss time is obviously shortened, and the efficiency of the battery replacement type electric ship is improved.
本申请实施例提供一种船舶换电方法和船舶高压系统,涉及船舶换电技术领域。船舶换电方法包括:接收电池管理系统发送的当前接入的电池包电量信息;当当前接入的电池包电量小于第一设定值且换电模式可行时,向DC‑AC控制器发送降低电机功率指令;根据DC‑AC控制器发送的降低电机功率进度信息,执行换包控制逻辑。由于不使船舶电机停止之后再进行换电,而是降低电机功率,使电机功率降低到安全范围内,就进行换包,相比电机停止再换包的方式,明显降低了动力丢失时间,提高了换电式电动船的效率。
