Abstract: A charging station capable of guiding a self-driving device to interface includes a base plate installed in a working area to fix the self-driving device; a first wire surrounding on the base plate and connected to a signal generator independently of a boundary; a second wire surrounding on the base plate and connected to the signal generator independently of the boundary and the first wire; and the signal generator sending a guide signal to the first wire and/or the second wire; where multiple areas surrounded by the first wire and the second wire include at least a first area having a first magnetic field signal, a second area having a second magnetic field signal, and a third area having a third magnetic field signal.

Abstract: A charging device includes: a power interface configured to access a power supply; and a charging interface configured to be detachably connected to a battery pack. The charging interface includes: a charging terminal configured to be connected to a charging terminal of the battery pack; a communication terminal configured to be connected to a communication terminal of the battery pack; and a communication module receiving the communication information of the battery pack. The charging device further includes a communication protection module connected between the communication terminal and the communication module and configured to isolate an interference voltage signal higher than or equal to a preset voltage value to protect the communication module.
