Abstract A non-contact wireless charging method is proposed in this paper in response to the charging problems of an automated guided vehicle (AGV) applied in the automated factories. Some problems such as an unsecure charging, an interface aging and a low automation level brought by the traditional centralized artificial charging manner can be solved by this method. Firstly, a simulation model of the resonant system with a structure of the primary-secondary side based on the principle of wireless energy transfer technology is established. Secondly, a hardware platform is designed to meet the AGV system based on a theoretical calculation. As a result, an adjusted distance range from 20～35mm between transmitter and receiver, a constant charging current for six lead-acid batteries (each has a capacity of 120Ah) and a high efficiency up to 80% is achieved. Moreover, a detailed analysis of the output power and efficiency is made with different coil distances and different kinds of load. Then a load characteristic curve, optimal transfer power and transfer efficiency curves are shown which can meet the system requirements.
