The design uses a low-power microcontroller STC12C5A60S2 energy transfer charger as a wireless monitoring and control core,based on the principle of electromagnetic induction, through energy coupling coil, to achieve energy transfer, the current control, voltage control, achieve transmission distance 5cm, the voltage reaches 5V, 0.5A current steady power supply, after the prompt is given full power and full automatically stop charging。Charging voltage and charging current display with low power LCD1602.System has a wireless charging, energy transfer effect is good, low cost, no wiring, easy to carry and other advantages, has a broad application prospects. Keywords—STC12C5A60S2 MCU intelligent wireless charging distance can reach 5-10cm, voltage 5V, 0.5A current FOREWORD stable charging. Has simple, wireless transmission distance is long, low-cost advantage. In the design of PHONE needs the corresponding charger, most single chip microcomputer and LCD power chargers can not be universal and compatible portable consumption is more, lead to the problem of lower wired charger and charge the user is not easy. So a no charging current, so use low-power chips and liquid charger charging technology to be developed. Nokia crystal display, the charging current can be improved. 920 handset with a wireless charging technology, using electromagnetic induction principle, sending and 1 THE HARDWARE SYSTEM DESIGN receiving end have a coil, transmitter coil is connected wired power generating electromagnetic signals, The wireless charging system design using Receiver coil induction sending electromagnetic electromagnetic induction principle, the use of coil signals to generate current to the battery. But Nokia coupling to transfer energy. Due to the wireless 920 wireless charging, you need to put the transmission of power voltage with energy sending corresponding wireless charging plate, once more than unit and receiving unit coupling coil spacing D may 2 cm can not be charged, and the production process is change in the test, lead to different charging voltage complicated, expensive, visible increase the change of distance, design considerations for safety, so transmission distance is a wireless charging charging ways on the choice of constant voltage technology should pay attention to the issue. This charging scheme. On the device select select has a design uses the same principle of electromagnetic variety of power saving
