Development and Application of AGV Energy System Based on Contactless Power Supply

Contactless Power Supply (CPS) uses electromagnetic coupling technology to supply power without mechanical contact. It is mostly used for mobile equipment, which has great advantages in safety, flexibility, maintenance costs and other aspects. In response to the 24-h uninterrupted and unmanned operation requirements of modern smart factories, this paper constructs an energy system composed of CPS, the lithium iron phosphate battery and the inverter to supply power for Automated Guided Vehicles (AGVs), and monitors and controls the working state of the battery in real time through the battery management system (BMS), so as to effectively extend battery life. After the charging efficiency test and practical application test, it has been verified that the proposed design scheme can enable the production line to realize the 24-h uninterrupted operation without manual intervention, which meets the demand of reliable and stable manufacture.
