Embodiment Construction

[0013] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0014] As far as user experience is concerned, the need for charging speed improvement is far greater than charging efficiency. This invention does not change the charging circuit, but changes the structure of the rechargeable battery to increase the charging speed, thereby improving the performance of wireless charging. Traditional wireless charging uses a single receiving end, resulting in a slow charging speed. This design uses multiple receivers, placed in parallel. When charging, the battery at the receiving end is placed in the battery box in a parallel array, and it is charged at the same time, which greatly reduces the charging time; after charging, the battery box supplies power to the device. On the one hand, this invention ensures the convenience and safety of wireless charging, on the other hand, it solves the problem of too slow charging speed of...

Abstract

The invention relates to a parallel array plane rechargeable battery for magnetic coupling resonant wireless charging, and the rechargeable battery comprises a battery box and a plurality of groups ofrechargeable battery modules located in the battery box, wherein each group of rechargeable battery modules comprise a miniature coil, a miniature charging module, and a small battery. All small batteries have the same capacity, and all miniature coils are parallel to each other, and are used for collecting energy in a high-frequency magnetic field. The energy collected by each miniature coil isrectified through the miniature charging module, and then is used for charging the small batteries.

Description

technical field [0001] The invention relates to a parallel array rechargeable battery applied to the magnetic coupling resonant wireless charging technology. Background technique [0002] With the popularization of wired charging technology and low-power consumption electronic products, the unsafety and inconvenience of wired charging are becoming more and more obvious. The battery life of low-power electronic products has also become an important indicator for evaluating product performance. In recent years, the emergence of electric vehicles has brought new challenges to wireless charging technology, and the charging rate of wireless charging has also become a major problem restricting its development. Under the background that the wireless charging rate is difficult to increase and the battery life is restricted, the present invention proposes a parallel array rechargeable battery applied to the magnetic coupling resonance wireless charging technology. [0003] With the ...
