Battery replacement method of mobile robot and automatic working system

The invention provides a battery replacement method of a mobile robot and an automatic working system. The battery replacing method comprises the following steps: enabling the mobile robot to execute a pre-positioning process so as to enable the mobile robot to move to a battery replacing operation position outside a target battery replacing station; enabling the target battery swap station to synchronously execute at least two floating adjustment processes; wherein one floating adjustment process is a temporary power supply docking process; and the other floating adjustment process is a plane error adjustment process. According to the battery replacing method, the occupied area of the battery replacing station and the setting complexity of the battery replacing station can be reduced, meanwhile, the battery replacing preparation time can be shortened under the condition that the alignment precision is guaranteed, and therefore the battery replacing efficiency is greatly improved. 本申请提供一种移动机器人的换电方法及自动工作系统。该换电
