Abstract

The invention provides an equivalent static simulation method of dynamic wireless power supply based on an open-circuit voltage of a receiving end, belongs to the field of wireless electric energy transmission, and solves the problem that a scheme argumentation stage is time-consuming and labor-consuming since a practical dynamic driving platform needs to be established to conduct experiment argumentation and condition tests on a dynamic wireless power supply system in the prior art. According to the static simulation method, the reception of a coil open-circuit voltage by a dynamic wireless charging device is simulated through control of a current of a transmitting coil Lp of a static wireless charging device so that the dynamic-to-static simulation is realized. The method is mainly usedfor simulating dynamic wireless power supply.

Description

technical field [0001] The invention belongs to the field of wireless power transmission. Background technique [0002] Dynamic wireless charging technology can realize battery charging or direct drive power supply of electric vehicles during driving, which has a very positive effect on improving the cruising range and energy utilization efficiency of electric vehicles. In the early research and development of dynamic wireless power supply technology, R&D personnel need to build an experimental test platform that is close to the characteristics of actual vehicle driving conditions. In order to meet the test requirements of high-power and high-speed driving, the test platform has to invest a lot of money to build and meet the test requirements. The required sports car site and the laying of a considerable length of launch guide rail, but the direct construction of a dynamic wireless power supply test platform is quite time-consuming and expensive for the early stage of the pr...
