Widely used in automatic logistics system, in the logistics system for horizontal transport equipment of automatic guided vehicle, is an important part of logistics system. AGV usually powered by batteries, also useful Contactless energy transmission System, the CPS (Contactless Power System) for Power. At present the study of AGV energy supply system such as charger design is less, in addition the current new charging stations commonly practiced unattended or less unattended, this requires the reliability of...
