Can Apple's new patent invigorate the wireless charging market?

1, Recently, it was disclosed that Apple applied for a patent, the future iPhone model can not only allow for unlimited charging of other devices, but also do not need to carry out "back-to-back" charging. In other words, the inductive current can be directly passed through the front display when wireless charging, without the need to reverse the phone on the back. Apple Brand NewThe unlimited charging method will undoubtedly bring a new storm to the future of wireless charging.

2, May, Apple submitted a "wireless power system" patent to show this innovative idea. Unlike previous battery cases, this new design does away with the lightning protection connector in favor of two-way wireless charging technology. According to the patent, the new battery case will be equipped with two sophisticated "switching circuit" wireless charging coils, which means that it will not only charge itself, but also power a connected iPhone or other wireless device, enabling true wireless interaction.

3, Apple's new patent reveals wireless chargingRecently, a new patent submitted by Apple has aroused wide attention in the industry. Unlike the common NFC technology on the market, Apple's patent seems to aim at the practical application and efficiency improvement of wireless charging technology.

4, the patent does not detail specific application scenarios, we can only expect Apple to reveal its actual use in a future release. Apple has always been, even after the iPhone 5 was questioned by the outside world lack of innovation, but its actual actions still show the pursuit of practicality and perfection. Wireless charging is not new to Apple, and the introduction of panoramic photography is not the first time, butApple always optimizes its technology to the best.

5. The scenario shown in the patent is stunning: iphones, ipads and MacBooks are magnetically connected to form a dynamic wireless charging network. The system can intelligently identify low-battery devices and automatically charge them, thanks to advanced software integration, making the user experience smoother. Apple's problems with traditional charging methods, such as the inconvenience of cables and chargers, this patent is undoubtedly a solution. 6, Conclusion: A new patent from Apple reveals a revolutionary wireless charging technology that will say goodbye to the phoneIn order to understand the workmanship of this product, the next thing to bring you is its unpacking.

What chip is needed for wireless charging?

At present, the most used is Ti's chip, about 12 pieces. There are many options for launch, and we're one of them.

Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.

But using NFCWireless charging, the power and today's maximum 40W or even higher technology is not comparable. According to the NFC Forum, WLC (Wireless Charging via NFC Solution) can use an antenna in NFC-enabled devices to manage communication and charging, so currently only 1W charging speed can be achieved through this solution.
