If you can transmit power over a longer distance, and can transmit higher power, it is necessary to talk about another medium range wireless charging technology wireless charging coil production , which can carry out electromagnetic resonance technology for energy transmission over a longer distance. Its advantage is that the transmission distance is much greater than the electromagnetic induction, can be carried out more than 10cm electromagnetic induction energy transmission, even in the larger distance of the transmission distance, the transmission power can still beTo reach several kilowatts.
Not only Japan, there are many countries are studying wireless charging road, at the end of last year, the world's fourth largest automobile manufacturer Stellantis announced on the official website, their innovative dynamic induction charging technology after years of research and months of testing proved successful wireless charging coil production The road "Arena del Futuro" for wireless car charging testing has been officially opened. So now wireless charging technology is also a very hot ranks.
Wireless charging technology for electric vehiclesIt mainly uses the mutual inductance in the law of electromagnetic induction. It is also similar to a transformer, which inputs from the primary coil and then generates an induced current on the secondary coil. It mainly relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
For pure trams, the most reliable solution now is electromagnetic induction, which is more stable and reliable. Magnetic resonance than electromagnetic induction although it can have a higher power distance advantage (a few centimeters to a few meters)>

In the wireless charging concept stock list, there are many companies focused on the development and promotion of wireless charging technology, these companies have great potential and competitiveness in the market. This article will introduce four leading wireless charging concept stocks and discuss their development prospects and market impact. Company A: A leading provider of wireless charging technology Company A is a company focused on the development and supply of wireless charging technology.
1, open the back cover of the smartphone wireless charging coil production , and then take out the wireless charging receiver ready; Or the protective layer of double-sided tape peel; The next task is to connect the receiver's metal shock to the smartphone battery wireless charge coil production Wireless charge coil production wireless charging coil production , ensure that each metal shock is connected together can be done.
2, the ordinary 555 time base circuit frequency is designed to be 8KM to be used, with 0.8 enamoured wire on a cylinder with a diameter of 5 mm around 11 laps and 9 layers to make two spare, the power supply uses 19V switching power supply (remember, must switch power supply), and makes a charging circuit (at your own discretion). I used the original mobile phone universal charger to remove the input and transform).
3Question 1: How to make wireless charger? There are many ways to use wireless chargers, mainly to see how the reception is installed. But no matter what the product is close, the operation method is placed on the launch plate. Take the mobile phone for example, the current mobile phone is generally added a mobile phone jacket, in this jacket there is a wireless receiver module. The phone can be charged wirelessly with this jacket.
4, the principle is very simple, stick the charging coil inside the mobile phone battery cover, paste the screen wallpaper, and then connect the positive and negative electrodes to the mobile phone usb power supply. You can put your phone on the Touchstone transmitter and make it wirelessIt's charged.
