Title:
PROTECTIVE CASE, METHOD, AND SYSTEM USED FOR WIRELESS POWER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2020/253757
Kind Code:
A1
Abstract:
Provided are a protective case (102), method, and system used for wireless power transmission, comprising: the protective case (102) is internally provided with a physical interface, a processor, and a wireless power transceiver; even if the first electronic device (101) does not have a function for wirelessly charging another electronic device, the electric energy of the first electronic device (101) can be transmitted to the protective case (102) by means of the physical interface, and the processor in the protective case (102) can generate a wireless transmission instruction so as to instruct the wireless power transceiver to perform wireless power transmission to a second electronic device (103) according to the received electric energy; thus the first electronic device (101) which does not have the function of wirelessly charging another electronic device can also supplement or provide power to the second electronic device (103), and further, the second electronic device (103) can be recharged by the first electronic device (101) when there is a charging demand.
