The desire of this thesis is to highlight the technology of the Wireless Power Transfer (WPT) systems for a specific class of industrial vehicles, forklift trucks operating in a warehouse, it is important to say that the control structure that will be implemented will be suitable for many electric vehicle classes. The entire project will be devoted to the study of the wireless static and occasional charging process in order to create a functional and precise state machine able to control the entire system. The created state machine will represent the system under analysis in a more intuitive way highlighting all the main variables to control.
