DIY solar wireless charger

This design is easy to use and is suitable for most electrical appliances that can accept electromagnetic fields. It is very convenient, and can get free electricity when the sun comes out.

Take a look at the overall block diagram of the design:

Step 1: Design raw materials

Making solar wireless charger materials

Making Solar Wireless Charger Tool 1 Soldering iron, 2 soldering iron stand, 3 soldering tin, solder, 4 rosin, 5 tweezers, 6 needle-nosed pliers, 7 tongs, 8 vise, 9 strippers, 11 high temperature sponge , 12 glue gun, 13 glue stick, 14 insulation tape, 15 multi-function screwdriver

Step 2: Principle of wireless charging

This design uses solar energy for power supply (using 12V 100W high-power solar panels, sufficient power), and a voltage regulator circuit is added behind the panel. When the voltage is too large, 12V voltage regulation can protect the circuit of the latter stage from burning out. When the voltage is too low, the circuit is turned off and the power is prevented from flowing back to cause unnecessary loss. In order to prevent the solar panel from generating electricity at night, this design adds a 12V battery (the battery is an ion battery, which is safe and reliable and not easy to explode). The solar energy and the battery power are converted to a magnetic field by the wireless transmitting module (also called the power transmitting module can emit a large electromagnetic field)

The following is handed over to an accepting module in the room. The direction of the electromagnetic coil of the receiving module is the same as the direction of the transmitting, and the electromagnetic field of the transmitting end is received. When the receiving coil is closed, a voltage equal to that of the transmitting end is generated. We then convert this voltage (here we intend to use the inverter on the market, reliable and powerful), it becomes the required voltage.

Step 3: Solar Wireless Charger Manufacturing Process

The first step: design the simulation of the circuit, using the professional circuit to carry out the simulation experiment. The second step: after the experiment is successful, the third step of the circuit construction: the circuit is lapped (the circuit is overlapped according to the schematic diagram). Step 4: Circuit Test Run Step 5: Design the overall test.

Step 4: Practical application of solar wireless charger

Wireless transmission module, the component area is small, no receiving current can be up to 600mA, basically meets the charging and power supply of common electronic design, the module has the recognition ability, can automatically increase or decrease the transmission power according to the load size, the working efficiency is about 70%, installation Convenient and simple, the price is low, it can work directly at 4~12V wide voltage. It is mainly used for wireless power supply and charging design of portable electronic small design. It has the characteristics of small size, easy to use, high conversion efficiency and low price. . Mainly used in: mobile phones, game consoles, fish tank lighting, MP3, MP4, digital cameras, electric razors, learning machines, medical, underwater products and other applications.

Future vision: bury a transmitting coil at the top and bottom of the building, using solar energy to wirelessly power the entire building.
