Description

technical field [0001] The present invention relates to a dynamic wireless power transmission system, in particular to a dynamic wireless power transmission system and a passive control method thereof. Background technique [0002] With the rapid development of modern society, traditional fossil energy can no longer meet the daily needs of human beings. In addition, traditional fossil energy has also caused serious environmental pollution problems. Therefore, the development of clean energy is imperative. As one of the most important means of transportation in modern society, the problems caused by traditional fuel vehicles have become increasingly prominent. With the rapid increase in the number of vehicles in the world, fossil energy can no longer meet the needs of fuel vehicles, and fuel vehicles have also caused huge damage to the environment. In the context of global environmental degradation and energy shortages, it is increasingly important to develop, promote and ...

Problems solved by technology

The static wireless charging method has strict restrictions on the charging area, and the user must go to the designated area for charging, and during the charging process, the electric vehicle cannot drive

Due to the limitation of the capacity and volume of lithium batteries of electric vehicles, electric vehicles cannot travel long distances. It is an ideal charging method to fully charge electric vehicles in a short period of time. Therefore, static wireless charging facilities are required to provide a high charging power for Shortening the charging time of electric vehicles is a technical difficulty of static wireless charging technology
