A battery charging system includes: an electric motor including stator coils; a battery; a charge port configured to receive power from charging stations by wire; first and second electrical conductors connected between the battery and the charge port; an inverter module including (a) inputs connected to receive power from the battery and (b) outputs connected to the electric motor; a third electrical conductor; and a switch configured to electrically connect and disconnect a first end of the third electrical conductor to and from the first electrical conductor, where the third electrical conductor includes a second end that is connected to at least one of the stator coils via one of the outputs of the inverter module.

A charging pile for sweeping robot including a main body, a storage component, a charging head, a charging cable, and a circuit board. The main body is provided with a first slot. The storage component, provided with a charging interface and an avoidance slot. The charging pile for sweeping robot includes a first mounting post movably connected to the main body. The charging cable is partly wound on the first mounting post, one end of which is detachably connected to the charging interface, and the other surrounds the first mounting post and penetrates through the avoidance slot and is fixedly connected to the charging head. The charging interface is electrically connected to the main body, so the charging cable can be wound on the first mounting post and contained in the first slot, prevented from being scattered on ground, and making the charging pile more beautiful when in use.
