Problems solved by technology

[0004] When the types of receivers are different or the charging requirements are different, the transmitter is often unable to provide wireless power supply according to actual needs. The current charging method will cause the equipment that needs to be charged to be fully charged within the specified time.

Abstract

The invention discloses a multi-device resonant wireless charging system comprising a receiving terminal, a collector, a priority calculation unit, a wireless transmission module, and a transmitting terminal. The receiving terminal is arranged on devices needing to be charged. The collector collects device information from the devices needing to be charged, and sends the collected device information to the priority calculation unit through the wireless transmission module. The priority calculation unit calculates out the charging priority of each device according to a priority calculation formula, and sends the calculated charging priority of each device to the transmitting terminal. The transmitting terminal charges each device according to the received charging priority of each device. The invention further provides a charging priority judging method employing the charging system. One-to-many wireless charging is optimized effectively, and the charging efficiency is improved.

Description

technical field [0001] The invention belongs to the field of wireless charging, and in particular relates to a multi-device resonant wireless charging system and a charging priority judging method. Background technique [0002] With the vigorous development of the electronic information industry, the power consumption of portable electronic products is increasing. Under the premise that the battery itself cannot make a major breakthrough in the short term, wireless charging technology has become a feasible and convenient solution. At present, two wireless charging technologies, magnetic induction and electromagnetic resonance, have received widespread attention, and the former has already entered people's daily life. However, the actual effective charging distance of this technology is only at the millimeter level, and it only supports one-to-one fixed-point low-power charging, so its application is limited. However, electromagnetic resonance wireless charging can not only...
