The invention discloses an overwater movable energy storage cabin and an electric ship power supply and conversion method based on the energy storage cabin. Comprising a charging station, an energy storage cabin and an auxiliary ship. The plurality of charging stations are reasonably distributed in a coastal area of a water transportation channel, and each charging station is provided with a plurality of charging berths with charging devices. And each charging station is provided with a plurality of energy storage cabins for charging and standby. The energy storage cabin is dragged by the auxiliary ship or driven by the power of the energy storage cabin to move to the electric ship passing through the water area near the charging station, the energy storage cabin is connected with the electric ship for power supply, and the feed energy storage cabin is replaced. Each energy storage cabin is in the shape of a boat, floats on the water surface and can be dragged to move, and the energy storage cabins provided with the power systems can move automatically. The energy storage cabin comprises but is not limited to a shell, a wireless communication module, a global positioning system, an energy storage module arranged in the shell, a charging and discharging module, a charging interface and a discharging interface arranged on the shell, and a plurality of dragging connecting devices. In the working process, the energy storage cabin is dragged by the electric ship to follow or keeps following through power of the energy storage cabin, and meanwhile power is supplied for endurance. When the electric ship exchanges power, the exchanged feed energy storage cabin is dragged by the auxiliary ship or travels back to a nearby charging station to be charged for standby application through the power of the auxiliary ship. According to the overwater movable energy storage cabin and the power supply and battery replacement method for the electric ship, the problems of low endurance and low battery replacement efficiency of the electric ship can be effectively solved, and high wharf construction cost in a container energy storage cabinet battery replacement technology is avoided.

    本发明公开了一种水上可移动储能舱和基于这种储能舱的电动船舶供换电方法。包括充电站、储能舱、辅助船。所述充电站有多个,合理分布于水运航道的沿岸区域,每个充电站有多个带充电装置的充电泊位。每一个充电站布置有多个储能舱充电并待命。储能舱在所述辅助船拖曳或者在自身动力带动下移动到途经充电站附近水域的电动船舶处,并连接电动船舶进行供电、换下馈电储能舱。单个所述储能舱外形为船艇样式,浮在水面上,可拖曳移动,装有动力系统的储能舱可自行移动。储能舱的内容包括但不限于壳体、无线通信模块、全球定位系统、置于壳体内的储能模块、充放电模块、置于壳体上的充电接口和放电接口、多个拖曳连接装置。工作时储能舱由电动船舶拖曳随行或靠自身动力保持跟随的同时供电续航。电动船换电时,换下来的馈电的储能舱由辅助船拖曳或者自身动力行驶回附近充电站充电备用。本发明提供的水上可移动储能舱和电动船舶供电换电的方法可以有效解决电动船舶的低续航,换电效率低的痛点,避免了集装箱储能柜换电技术中高昂的码头建设成本。
