Abstract

The invention discloses a wireless power transmission system for AGV and a control method thereof. The system includes a ground wireless power transmission system and an AGV wireless power receiving system. The invention adopts wireless charging instead of wired charging to improve the safety of the AGV charging system ; Adopt the electromagnetic resonance wireless power transmission method to increase the transmission distance; adopt the charging strategy combining fast charging and slow charging, while ensuring the service life of the battery, it improves the working efficiency of the AGV and realizes the automatic operation of the AGV.

Description

technical field [0001] The present invention relates to the technical field of wireless power transmission, in particular to an electromagnetic resonance wireless power transmission system and method for AGVs. Background technique [0002] AGV is a mobile robot with a guiding device and a microcomputer control system that can accurately travel along the guiding path. AGV has strong adaptability, high work efficiency, and can realize 24-hour unattended operation. It has played an important role in many fields such as mechanical processing, automobile assembly, tobacco industry, logistics storage and transportation, and steel smelting. AGV generally uses rechargeable batteries as its power source. During operation, the voltage of the battery pack will gradually decrease, and the electric energy stored in the battery will gradually decrease. Therefore, it is necessary to replenish electric energy regularly during the cycle operation. [0003] Traditional AGVs mostly use trolle...
