2, we often say that wireless charging actually has a great limit, the effective distance oneGenerally only 8mm - 15mm, in this range can be normal wireless charging, the so-called space is separated by a mobile phone shell empty only. If there is a metal interval, it will affect the normal charging.
3, the technical principle, Qi charger and receiving equipment built-in conductive coil, the electromagnetic field generated after the base is energized will promote the coil in the receiving equipment into electrical energy, to achieve efficient and convenient wireless power supply. Although the Qi 2 standard supports fast charging up to 15W, the limitation of charging distance (typically a few millimeters to a few centimeters) remains a technical challenge. Qi wireless charging of the two brightThe point is its convenience and versatility.
First of all, not all wireless chargers on the market can be competent for watch charging. Many products do not clearly label the radiation value, which is somewhat worrisome. Because the radiation standard of wireless charging technology has not yet been perfected, we need to be concerned that the current regulatory requirements, such as the "Electromagnetic radiation Protection Regulations" stipulate that the electromagnetic radiation of the user in continuous contact with the wireless charger within 24 hours shall not exceed the specific absorption rate of 0.02W/kg (SAR) restrictions.
Take 1000mAh capacity lithium battery as an example to calculate wireless charging qi standard radiation of wireless charger. 50% charging capacity is about 7~8Wh. If it is required to be full for about two hours, the maximum charging power should reach at least 1W (the maximum power of GSM900 mobile phone is about 2W) Wireless charging qi standard ; Since the wireless charging method of the phone is to place the phone above the charger rather than inside, the radiation leakage rate can be not small.
Test found: makeWith a high-sensitivity radiation meter, the radiation value of the wireless charger is between 150 and 180, although it is smaller than the 250 to 627 in front of a computer screen or the thousands when making a call on a mobile phone, but the cumulative effect may not be negligible. At the same time, when wireless chargers, mobile phones, computers and other electronic devices are used together, the radiation value will increase significantly.
According to the Electromagnetic Radiation Protection Regulations, the average radiation absorption rate of the whole body should be less than 0.02 w/kg within 24 hours a day for 6 consecutive minutes. However, there are no specific standards for wireless charging. Experts say, thoughPaving the way for functional development.
Qi2 charger is a wireless charging device based on the Qi standard, which uses electromagnetic induction technology to provide wireless charging capability for electronic devices. Qi is the world's first wireless charging standard, launched by the Wireless Power Alliance (WPC). It uses electromagnetic induction technology to transmit electrical energy from the charging device to the receiving device. The Qi standard aims to achieve the standardization and universality of wireless charging, so that different brands and models of equipment can be wireless charging through the Qi standard.
Qi2, is an innovation in the field of wireless charging. WPC Wireless Charging Alliance,Since its establishment in 2008, it has been committed to promoting the standardization of wireless charging technology worldwide. Based on the Qi 3 protocol, the Qi2 standard introduces the MPP protocol and magnetic alignment technology, the operating frequency is increased to 360kHz, the foreign body detection function is enhanced, and the MPP and EPP modes provide 15W efficient transmission capacity, and the future is expected to achieve higher power wireless charging.
Security and protection: qi has been enhanced in terms of security, including the protection of electromagnetic wave interference and the improvement of safety mechanisms, and has adopted a variety of safety measures to ensure the stability and safety of the wireless charging processqi2 has been further optimized and enhanced in terms of security, adopting more stringent security standards and safeguards to prevent potential security risks and electromagnetic interference issues.
Wireless charging refers to the charger on the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. How to use: Connect the USB cable and plug it into the socket.
QI certification is the Wireless Charging Alliance certification, that is, WPC certification (Wireless? The Power? The Consortium is a collaborative group of independent companies that aims to create and promote widespread market adoption of Qi, an international wireless charging standard compatible with all rechargeable electronic devices. QI certification is an authorized mark for wireless charging products, and only products that have been rigorously tested to ensure safety, interoperability and energy efficiency can use the QI certification mark.
qi certification is WPC wirelessOnly products certified by the WPC Alliance can use the QI certification mark, which is similar to the BQB certification of the Bluetooth Alliance. Up to now, the wireless charging alliance WPC has more than 600 members, more than 800 products have obtained QI certification, WPC has an absolute advantage in the field of wireless charging standards.
This certification is a certification that complies with the wireless charging standards established by the Wireless Charging Alliance (WPC). Qi certification refers to wireless charging that complies with the Wireless Charging Alliance (WPC)Certification of electrical standards. The Wireless Charging Alliance (WPC) is a global organization dedicated to developing and promoting standards for wireless charging technology.
