Abstract

An anti-theft cable (10), comprising two built-in anti-theft wires (11) forming a loop. A resistance detecting device (15) is connected in the loop. When the cable is cut off, the circuits of two anti-theft wires (11) are disconnected, the two anti-theft wires (11) form an open circuit, and the resistance value detected by the resistance detecting device (15) is infinite. An automobile charging system, comprising a charging device, a charging cable, and a charging gun. One end of the charging cable is connected to the charging device, and the other end thereof is connected to the charging gun. The charging cable is the anti-theft cable (10), and the resistance detecting device (15) is provided in the charging device. The resistance detecting device (15) feeds back the detected resistance value to the charging device, and when the resistance value received by the charging device is infinite, the charging device disconnects the charging circuit and instructs an alarm to alert. When the circuits of the two anti-theft wires (11) are disconnected, and the resistance value detected by the resistance detecting device (15) is infinite, so that the case that the wires are being stolen can be detected and found in time.

Abstract

A cable, a wire, and a charging equipment cooling system using the cable. The cable comprises a plurality of main conductors (1, 3) and main insulating layers (5, 6) coating the main conductors, wherein the main conductors are internally provided with cooling pipes (2, 4), and the cooling pipes transfer cooling fluids for cooling the main conductors. The wire comprises a conductor, the conductor is internally provided with a cooling pipe, and the cooling pipe transfers a cooling fluid for cooling the conductor. The cable and the wire can minimize the temperature of the conductor.

Abstract

A wireless charging power coil, a wireless charging system and a wireless charging control method. The wireless charging power coil comprises a first coil (1), a second coil (2) and a switching apparatus, wherein the first coil (1) is connected to the second coil (2); when a current rotation direction in the first coil (1) is the same as a current rotation direction in the second coil (2), it is in a polar charging mode; when the current rotation direction in the first coil (1) and the current rotation direction in the second coil (2) are opposite, it is in a non-polar charging mode; and the switching device is used for switching the wireless charging power coil to operate in the polar charging mode or in the non-polar charging mode, so that the costs are reduced, and the charging efficiency is improved.

Abstract

An alignment method for a wireless charging coil, an apparatus and a system. The alignment method for a wireless charging coil comprises the following steps: acquiring an electrical parameter related to the charging of a power supply end coil and/or a vehicle end coil (S100); according to the electrical parameter, adjusting the position, in a horizontal direction, of the power supply end coil (S200); and determining whether an electrical parameter value reaches a pre-set electrical threshold value and/or whether the number of times of adjustments reaches the pre-set maximum value (S300), if so, the alignment of charging coils being completed, and if not, circulating the steps. The alignment method for a wireless charging coil, apparatus and system increase the alignment speed of wireless charging coils and improve the charging efficiency.

Abstract

Disclosed is a drive wheel set, comprising a common shaft and at least two external rotor motors installed on the common shaft. External rotors of the external rotor motors form drive wheels of the drive wheel set. Also disclosed are a vertical-type wire storage frame, a swing-type wire storage frame, a guide wheel frame, a traction mechanism and a multi-path conveying mechanism using the drive wheel set. The drive wheel set is small in size, occupies less space, and is suitable for a situation where a plurality of motors need to be driven but sufficient space is lacking.
