New standard of wireless charging: In-depth analysis of Qi certification wireless charging technology South Korea wireless charging certification Popularity South Korea wireless charging certification is inseparable from strong technical standard support. Qi Certification, full name Qi Wireless Charging, is a global Wireless charging standard developed and implemented by the Wireless Power Consortium (WPC).
Wireless charging Qi test includes Compliance Test (Compliance test) and compatibility test (Interoperability Test), compliance test by the compliance test experiment ATL (Authorized Test Lab), 5 samples were sent for testing.
Qi certification: the universal language of Wireless charging industry Qi, the full name of the wireless charging Alliance (Wireless Power Consortium, referred to as WPC) masterpiece, it defines Korean wireless charging certification a global universal wireless charging standard. This standard takes "convenience" and "versatility" as the core to ensure that Korea wireless charging certification products of different brands only need to have Qi logo, and can be combined with any QiThe wireless charger is seamless.
Qi is the Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard South Korea wireless charging certification ; It has two characteristics of convenience and versatility. Qi certification test standard Qi standard 0 was released in July 2010, the current version is V4, and the WPC Charging Alliance expects the latest version V3 around April 2020 (there is likely to be a 3-6 month delay), the full V3 specificationReleased in WPC2001.
Wireless charging Qi certification types can be divided into three categories: BPP certification, EPP certification and PPDE certification. 1) QI-BPP certification: The product supports less than 5W power, the use of Qi protocol, must be BPP certification. 2) QI-EPP certification: The product supports more than 5W power, the use of Qi protocol, must be EPP certification. 3) Qi-PPDE certification: The product supports more than 5W power, uses Samsung private protocol PPDE, and must be tested by PPDE (from July 1, 2019).
WirelessQi certification content: including Compliance test and Interoperability Test. The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
1, final product confirmation; 7) Review and issue certificates. Qi certification process Wireless charging Qi certification test content includes: compliance test (Compliance test and Interoperability Test. The compliance Test is conducted by the Authorized Test Lab (ATL), and 5 samples are sent for test.
2, Qi certification testing content detailed Qi certification testing content is rigorous and comprehensive, mainly including: transmitter and receiver communication protocol: to ensure that both sides can quickly and accurately exchange data. Power output and stability: In the XYZ axis translation test, verify the wireless charging capability of the device at different anglesCharging technology Korea Wireless charging certification , that is, bipolar coil resonance system (DCRS) Korea wireless charging certification , it is expected to end the history of mobile phones relying on wires to charge, and can charge up to 40 smart phones at the same time within 5 meters. Not only that, this technology is also applicable to TV sets, fans and other devices, with a wide range of application potential.
Conclusion: The new wireless charging technology developed by the Korea Institute of Science is showing promiseA certain current is generated in the coil, which transfers energy from the transmitting end to the receiving end.
Wireless charging distance mobile phone and charger can not leave more than 10cm, the closer the effect is better. Wireless charging technology has always been only related to "small" mobile devices such as smartphones and small-size tablets. However, A4WP (" Wireless Charging Alliance "), one of the three major wireless charging camps, recently announced that its technical standards have been upgraded, and the charging power supported has increased to 50 watts, which means that high-power devices such as laptops and tablets can also achieve wireless charging.
It is the first generation of mobile phone wireless chargingElectricity, the technology is mature, but only single to single short distance charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging.

3, Qi certification test content detailed Qi certification test content is rigorous and comprehensiveIt mainly includes: the communication protocol between the transmitter and the receiver: to ensure that the two sides can exchange data quickly and accurately. Power output and stability: In the XYZ axis translation test, verify the wireless charging capability of the device at different angles. Energy transmission limit: Test the maximum power supply capacity of the equipment to ensure safety performance.
4, Qi certification test project compliance test. At least 5 samples are required to be sent to test, one of which will be scheduled for compliance testing first, and the compliance test sample will be retained in ATL after passing the test.

To a certain extent to protect the safety of the user the most worried about is whether wireless charging will produce a large amount of electromagnetic radiation South Korea wireless charging certification , and then affect human health. This infrared wireless charging device in the process of work, if the transmission road is blockedIn the case of the line, the power will be automatically reduced for protection. However, considering that it does not yet have the ability to distinguish between the human body and its physical object, the effect will certainly be greatly reduced when used in the partition wall.
is through the infrared device to achieve infrared charging, and in this way can better supply power, but also to allow the battery to get better protection.
Korea wireless charging certification I personally think this thing is not practical, because this is in an ideal situation, you canInfrared wireless charging for devices 30 meters away, and 400W of power, only 85W reaches the device here. I don't know, it's really not practical at this stage.
