As a new representative manufacturer of wireless charging industry in China, Yichong wireless presented a number of new products such as wireless charging transmitting board and receiving terminal chip, coil, magnetic material and module, which attracted the attention of the exhibition guests and industry people. The reporter found that the 4-coil and 16 coil wireless charging transmitting plate of easy Chong wireless in this exhibition can perfectly match the wireless charging mobile phone with embedded easy Chong ec4016 chip, realizing the free position charging, namely, charging without alignment, which greatly improves the freedom of mobile phone wireless charging.

Easy impact wireless 4-coil wireless charging transmitting board

It is understood that the current wireless charging mobile phones on the market are "point-to-point" charging. Users need to align the receiving coil of the mobile phone with the coil center of the wireless transmitter. If it is slightly misaligned, it will not be able to charge, and the use experience is very poor. The 4-coil and 16 coil wireless charging transmitting board of easy impact wireless solves this pain point and realizes free position charging. The user can place the mobile phone casually to realize charging. In order to achieve the charging effect of free position, Yichong wireless has designed hundreds of coils, and cooperated with the exclusive ECH protocol of easy Chong wireless. After a lot of simulation and experiments, the most suitable coil, as well as the appropriate coil driving voltage, current and frequency, is finally found out.

At the receiving end, the ec4016 chip supports a variety of wireless charging standards and is fully compatible. It can automatically identify the charging protocol at the transmitter. The charging efficiency is more than 80%. The maximum wireless charging power can reach 15W, which can realize wireless fast charging. With more and more functions of mobile phones, the battery capacity is increasing, but the main board of mobile phones is getting smaller and smaller. It is a great challenge to integrate the wireless charging circuit into the PCB of mobile phone motherboard while not changing the internal structure of the existing mobile phone. However, the ec4016 peripheral circuit of easy impact wireless is very few, which takes up a very small area of mobile phone motherboard, and can be easily integrated into the product design of mobile phone.

In the manufacturing of coils, magnetic materials and modules in the industrial chain of wireless rechargeable mobile phones, Yichong wireless, together with strategic partners such as shunluo electronics, Xinwei communication and Antai technology, exhibited the latest products and achieved technological breakthroughs in these links. For example, in the coil of receiving end, mqprf flat coil developed by Yichong wireless and shunluo Electronics Co., Ltd. reduces the thickness of substrate under the same power. Moreover, the coating film of enameled wire is thinner than that of FPC coil, the transmission efficiency of the coil is higher, and the thickness is far less than 0.3mm of the same line. At the same time, it can provide customized requirements and has good thermal management performance.
