Abstract
A self-loop detection method for a charging device includes switching a positive signal cable Do and a negative signal cable Do from a connected state to a disconnected state; and detecting whether a positive signal cable Di and a negative signal cable Di are switched from a connected state to a disconnected state; and if yes, determining that a self-loop exists in the charging device.
