Abstract

The invention provides a wireless charging control method and device, and belongs to the technical field of wireless power transmission, and the control method comprises the following steps: controlling a double-pole-double-throw switch to shift to the switching contact of a double-pole-double-throw switch during startup, and enabling a transmitting end to start to charge a no-load receiving end;detecting the charging voltage of the receiving end, and judging whether the charging voltage reaches a charging threshold value or not; if so, controlling the transmitting end to continuously chargethe receiving end, so that the receiving end charges the battery; and if not, stopping charging the receiving end by the transmitting end, controlling the double-pole double-throw switch to shift to the other switching contact, and then controlling the transmitting end to charge the receiving end, so that the receiving end charges the battery. The direction of the magnetic line of force is adaptively changed according to the transverse offset of the receiving coil, so that the wireless charging device has high offset resistance, adaptability and practicability, and has the advantages of high control reliability and high sensitivity.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a wireless charging control method and device. Background technique [0002] Automated Guided Vehicle (AGV) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, and is widely used In places such as logistics sorting stations. Rechargeable batteries are currently the only source of power for AGVs. At present, most AGV batteries use manual charging, battery replacement charging, automatic charging and other charging methods. Among them, the two methods of manual charging and battery replacement charging require full-time personnel to perform line connection operations or manually replace the battery pack, and special personnel are required to take care of related equipment, resulting in a r...
