Two major wireless charging standards
1. Qi standard
Qi is the world's first standardization organization to promote wireless charging technology - wireless charging alliance launched the \"wireless charging\" standard, with convenience and versatility of two major characteristics. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger. Secondly, it has overcome the technical bottleneck of wireless charging \"versatility\
The more mainstream wireless charging technology in the market is mainly through three ways, namely electromagnetic induction, radio waves, and resonance, and Qi uses the most mainstream electromagnetic induction technology. In terms of technology applications, Chinese companies are already at the forefront of the wireless charging industry. It is reported that Qi's application products in China are mainly mobile phones, which is the first stage, and will be applied to different categories or higher power digital products in the future.
2. Power Matters Alliance standards
The Power Matters Alliance standard is initiated by Duracell Powermat, which is a joint venture between P&G and Powermat, a wireless charging technology company, and has a relatively outstanding comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power Standards.
Already have AT& Three companies, Google and Starbucks, have joined the PMA alliance. The PMA Alliance is committed to creating wireless power standards for mobile phones and electronic devices that meet the standards of the IEEE Society, and has a leadership position in the field of wireless charging.
Wireless charging technology (Wireless charging technology; Wireless charge technology is derived from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging usually adopts a resonant mode (most electric vehicle charging uses this mode) by the power supply device (charger) to transmit energy to the electric device, which uses the received energy to charge the battery, and at the same time for its own operation.
Since the energy is transmitted between the charger and the electrical device by a magnetic field, no wires are connected between the two, so the charger and the electrical device can be exposed without conducting contacts.
There are five mainstream Wireless charging standards: Qi standard, Power Matters Alliance(PMA) standard, Alliance for Wireless Power(A4WP) standard, iNPOFi technology, and Wi-Po technology.

In terms of technology applications, Chinese companies are already at the forefront of the wireless charging industry. It is reported that Qi's application products in China are mainly mobile phones, which is the first stage, and will be applied to different categories or higher power digital products in the future.
2. Power Matters Alliance standards
The Power Matters Alliance standard is initiated by Duracell Powermat, which is a joint venture between P&G and Powermat, a wireless charging technology company, and has a relatively outstanding comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power(A4WP) standard.
Already have AT& Three companies, Google and Starbucks, have joined the PMA Alliance (short for Power Matters Alliance). The PMA Alliance is committed to creating wireless power standards for mobile phones and electronic devices that meet the standards of the IEEE Society, and has a leadership position in the field of wireless charging.
Duracell Powermat has released a WiCC charging card based on the Power Matters Alliance standard. Larger than an SD card, the WiCC is embedded with components such as coils and electrodes for electromagnetic induction contactless charging. The card is thin and can be inserted next to existing smartphone batteries, making it easy for many portable devices to support contactless charging.
3. A4WP standard
A4WP is short for the Alliance for Wireless Power standard, created by the Wireless Charging Alliance co-founded by Qualcomm, Samsung, and the aforementioned Powermat. The alliance, which also includes Ever Win Industries, Gill Industries, Peiker Acustic and SK Telecom, aims to set technical standards and an industry dialogue mechanism for wireless charging devices for electronic products, including portable electronics and electric vehicles.
4. iNPOFi technology
iNPOFi (\" invisible power field \"or\" invisible energy field \") wireless charging is a new wireless charging technology. Its wireless charging series products use intelligent electric transmission wireless charging technology, with no radiation, high energy conversion efficiency, weak thermal effect and other characteristics.
Compared with other existing wireless charging technologies, iNPOFi has no radiation, adopts electric field pulse mode, does not produce any radiation, and the test results of China Tel Laboratory show that the added value of radiation is close to zero. In terms of efficiency, Theil laboratory also determined that the product of this technology has a charging transmission efficiency of more than 90%, completely changing the low efficiency of the traditional wireless charging up to 70%.
In terms of intelligent management, chip adaptation management technology is used, including: automatically open and close the charging process; Automatically adapt the required voltage and current, and manage the charging process to ensure high charging efficiency; And can use a unified charging board for any brand, model of electronic products, safe, convenient and efficient charging. In terms of safety, while taking into account a variety of weak charge security issues, such as electrostatic ESD protection, anti-overcharge, anti-impact, etc., and even if the power management of the device itself has problems, you can automatically fuse through the inpofi chip to protect electronic equipment from being damaged.
It is worth mentioning that for smart device manufacturers, inpofi is based on a very small chip as the core to achieve ultra-fine design, only 1\/4 of the size of a fifty cent coin, which can be easily integrated into any device, and can also be integrated into various forms of wearable devices. This is the traditional electromagnetic principle of the product can not achieve.
As a new generation of wireless charging technology standard, iNPOFi technology is efficient, green, convenient and economical. The charging device using the technology includes two parts: a power transmitter and a power receiver. The size, thickness and thickness of the transmitter are similar to that of an ordinary mobile phone. The receiving device is embedded in the mobile phone protective cover, and the mobile phone is covered with the protective cover and placed flat on the transmitter for charging. During the charging process, the phone does not need to plug in any cable. The relevant test shows that the electromagnetic radiation is zero during the charging process, and the power efficiency conversion reaches 94.7%, which is close to the wired charging. The charging device supports low voltage power supply, compatible with ordinary USB power supply; Achieve low temperature charging, effectively ensure the use of equipment and battery safety and life.

5. Wi-Po technology
Wi-Po technology is a Wi-Po magnetic resonance wireless charging technology, which uses a high-frequency constant amplitude alternating magnetic field generation device to generate a resonant magnetic field of 6.78MHz to achieve a longer transmission distance.
The technology realizes communication control through Bluetooth 4.0, which is safe and reliable, and can support one-to-many synchronous communication, and also has over temperature, over voltage, over current protection and foreign body detection functions. Because the carrier of this technology is a space magnetic field, the energy will not be emitted like electromagnetic waves, so it will not cause radiation damage to the human body.
Wi-Po magnetic resonance wireless charging can be applied to mobile phones, computers, smart wearable, smart home, medical equipment, electric vehicles and other scenarios.
