Abstract

The invention discloses a wireless charging control method, wireless charging and a storage medium. The wireless charging control method is applied to a wireless charging control system. The wirelesscharging control system comprises an infrastructure side and a vehicle-mounted side, wherein the infrastructure side is provided with an internal control circuit and a primary side coil, the internalcontrol circuit comprises a PFC circuit, a BUCK circuit and an inverter circuit, and the vehicle-mounted side is provided with a secondary side coil and a full-bridge rectification circuit. The wireless charging control method comprises the following steps: acquiring an initial target current demand value Ip-req required to be reached by a primary side coil; adjusting the output current actual value Ip-fac of the primary side coil according to the acquired initial target current demand value Ip-req; judging whether a system output current actual value Iout-fac corresponding to the current actual value Ip-fac of the primary side coil reaches a vehicle-mounted side current demand value; and controlling the system output current actual value Iout-fac according to the judgment result. The technical scheme of the invention aims to ensure that the wireless charging system meets the charging requirement.

Description

Technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging control method, a system and a storage medium. Background technique [0002] With the development of new energy sources, more and more cars have begun to adopt electric or gas-electric hybrids. When charging electric cars, the principle of electromagnetic induction can be used to sample wireless charging. Wireless charging is a new type of charging technology that has emerged in recent years. It can charge within a certain space without using a charging cable. Its realization method is mainly based on the technology of wireless power transmission (Wireless Power Transfer), which uses the principles of magnetic resonance coupling, laser, microwave, etc. to transfer electric energy from the primary input voltage terminal to the electric equipment terminal in a non-contact manner, which can realize electricity consumption. The wireless charging / powe...
