目前，随着电池技术的不断发展，电池的应用场景也不断增多，如何快速补充电池的电能成为限制电池推广的因素之一。根据电池本身储存能量的原理，电池需要周期性的补充电能，且电池通过充电的形式补充电能时间较长。故通过为用电装置直接更换电池，使用满电电池替换损耗电池，能够有效提高为用电装置补充电能的效率。
但是，申请人发现，直接更换电池的方式，引入了电池拆卸、安装 及转运步骤，由于电池本身自重较大，拆卸、安装及转运步骤实现困难，尤其在使用吊具转运电池的过程中，电池在垂直于升降方向的方向上晃动幅度较大，电池无法精确与用电装置上的安装位置相对准，降低了安装的效率，也使得安装精度降低，进而降低更换效率，更明显的是，前述晃动也更易使电池磕碰换电站内的其他部件，造成电池损坏，影响电池的安全性。
基于以上考虑，为了提高电池的更换效率，本申请发明人经过深入研究，设计了一种转运装置及换电站，转运装置通过在吊具和基座上分别设置用于相互配合的第一配合部和第二配合部，以在转运电池的过程中限制吊具和基座两部分的相对移动，有效减少转运过程中的电池晃动，提高更换安全性，并便于电池与用电装置上的安装位置对准，提高更换效率。
本申请的实施例所提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。例如，电池可以包括电池模块或电池包等。
本申请实施例公开的用于更换电池的转运装置、换电站可用于车辆。车辆可以是燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。示例性地，用电装置可为重型卡车。

可选地，换电站还包括轨道501，转运装置500可移动地设置于轨道501。轨道501用于引导转运装置500的移动，以使转运装置500能够在停放平台400和电池仓600之间移动。示例性地，轨道501的一端延伸到电池仓600内，另一端延伸到停放平台400。轨道501可以布置于电池仓600的顶部，转运装置500在电池仓600的顶部沿轨道501行进，这样，可以减少电池仓600的占地面积。
可选地，电池仓600中可以另外设置有堆垛机，堆垛机用于将转运装置500拆下的待充电电池100转移到电池仓600的充电位进行充电，并将电池仓600存储的满充电池100放置在转运装置500上。或者，可由转运装置500在从用电装置拆下待充电电池100后直接将待充电电池100转运至充电位，并且，还可以由转运装置500将充电位上的满充电池100直接转运至用电装置上。
