Description
Technical field
The present invention relates to the parallel front formula rechargeable batteries applied to magnet coupled resonant type wireless charging technique.
Background technology
It is universal with wired charging technology and low-power consumption consumption electronic product, the insecurity of wired charging and inconvenient
Property increasingly show, the cruising ability of low power dissipation electron product battery also becomes the important indicator of evaluation properties of product.In recent years, it is electric
The appearance of electrical automobile brings new challenge for wireless charging technology, the charge rate of wireless charging also become restrict its development compared with
Big problem.It is difficult to improve in wireless charging rate, under the background that battery durable ability is restricted, the present invention proposes to be applied to magnetic
The parallel front formula rechargeable battery of coupled resonance formula wireless charging technology.
With the development of wireless charging technology, the technology that wireless charging is realized by electromagnetic induction has been gradually appeared, but
It is the problem of current wireless charging technology is perfect not enough, and charge efficiency is low, charging rate is slow generally existing.
Want employing wireless charging technique to charge for low power dissipation electron product, it is necessary to improve the performance of its charging：
It improves charge efficiency or improves charging rate.
Invention content
The object of the present invention is to provide a kind of wireless charging batteries that can reduce the charging time.Technical solution is as follows：
A kind of parallel front formula rechargeable battery applied to magnet coupled resonant type wireless charging, including battery case, positioned at electricity
Multigroup rechargeable battery component in the box of pond, every group of rechargeable battery component include micro-coil, miniature charging module and baby battery, respectively
A baby battery capacity is equal, and each micro-coil is placed in parallel, and for the collecting energy in high frequency magnetic field, each micro-coil is adopted
It charges after the rectification that the energy integrated passes through miniature charging module as baby battery.
The present invention has the following advantages due to taking above technical scheme：Common wireless charging is difficult due to inefficiency
Substantially to be applied.The invention ensure that quick charge by using the form of multigroup rechargeable battery.

Specific embodiment
The present invention will be described with reference to the accompanying drawings and examples.
For user experience, for charging rate promoted need be far longer than charge efficiency.The invention, which does not change, fills
Circuit, and change charging accumulator structure to improve charging rate, and then improve the performance of wireless charging.Traditional wireless charging
All it is using single receiving terminal, causes charging rate speed excessively slow.The design uses multiple receiving terminals, is placed in parallel.Work as progress
During charging, receive end-cell and be placed in battery case in parallel front formula, be carried out at the same time charging, greatly reduce the charging time；It fills
After electricity, powered by battery case for equipment.On the one hand the invention ensure that convenience and the safety of wireless charging, the opposing party
Face solves the problems, such as that wireless charging charging rate is excessively slow, and charging rate is accelerated in the case where ensureing safe current voltage.
The application scenarios of the parallel front formula rechargeable battery applied to magnet coupled resonant type wireless charging technique of the present invention
It is as follows：
(1) wireless charging transmitting terminal, including wireless charging transmitting module and transmitting end-coil and transmitting terminal communication module.
(2) it when starting to charge up, after transmitting terminal communication module receives the receiving voltage requirement of receiving terminal, starts to charge up simultaneously
Control supply voltage；Transmitting terminal wireless charging module by the DC voltage inversion received be alternating current, coil and transmitting at this time
The capacitance in wireless charging module is held to generate electromagnetic field of high frequency with high frequency velocity interpolation energy exchange；During charging, transmitter section communication
Module keeps the communication with receiving terminal communication module.
(3) wireless charging receiving terminal, including miniature charging module, baby battery, battery case and receiving terminal communication module.It is small
Charging module is integrated on baby battery, and each baby battery capacity is equal, to ensure the identical charging time.Baby battery is using type lithium electricity
Pond.Each group compact lithium cell and the equal run-in index of micro-coil are placed, and multiple micro-coils are placed in parallel so that each coil
As booster.Micro-coil is within high frequency magnetic field, and generating high-frequency energy with the capacitance in small charging module exchanges, and connects
Energy is received, is charged after rectification for compact lithium cell.
(4) receiving terminal communication module is monitored receiving voltage and feeds back to transmitting terminal communication module, to transmitting electricity
Pressure is finely adjusted, and is maintained at safe charge voltage.
(5) after battery is full of, charging module sends out a warning and feeds back to transmitting terminal communication module by receiving terminal communication module,
It is powered off, charging finishes.
