Abstract

A wireless charging method and system, a device controller, a charging pile and a storage medium, said method comprising: the device controller receives, sent by the charging pile, an automobile on-board charging device identifier and a charging pile identifier, and also binding request information for the automobile on-board charging device identifier and the charging pile identifier; when it is determined that the automobile on-board charging device identifier and the charging pile identifier are valid and that the charging pile identifier and the automobile on-board charging device identifier are compatible, the automobile on-board charging device identifier and the charging pile identifier are bound in accordance with the binding request information; the automobile on-board charging device identifier / charging pile identifier compatibility results, the automobile on-board charging device identifier / charging pile identifier validity results and the automobile on-board charging device identifier / charging pile identifier binding results are sent to the charging pile, thus allowing the charging pile to begin charging the automobile on-board charging device.

Description

technical field [0001] The invention relates to wireless charging technology, in particular to a wireless charging method and a wireless charging system for electric vehicles. Background technique [0002] The ever-increasing number of cars puts forward a high demand for oil and natural gas-based energy sources, while petrochemical energy sources are increasingly depleted, and oil prices will remain high in the long run. At the same time, the air pollution caused by vehicle exhaust is becoming more and more serious. Electric vehicles are powered by vehicle-mounted power supplies. Therefore, electric vehicles have the advantages of energy saving, environmental protection, and low noise. However, the development of electric vehicles still faces many technical problems, among which battery charging efficiency and deployment of charging stations are important issues. [0003] Battery charging technology is divided into wired charging and wireless charging. For wired charging ...
