1, AThe P45851 is compatible with high power output, and the chip is compatible with the Qi Fast charge protocol (5/9/12V application), which meets the latest Wireless Charging Alliance (WPC) Qi version specifications. The AP45851 uses the unique CNS-chip as System technology to fully integrate a variety of high-performance mixed-signal functions, such as low-power device detection during standby and foreign object detection (FOD) for secure wireless charging.
2, wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil at the sending and receiving ends, and a coil at the sending endA wired power supply is connected to generate an electromagnetic signal, and the receiving coil senses the electromagnetic signal at the transmitting end to generate a current to charge the battery.
3, play the role of metal isolation, prevent energy waste, improve charging efficiency. 4, wireless charger uses the latest wireless charging technology, through the use of the magnetic field generated between the coils to transmit power, without the wire this medium, inductive coupling technology will become a bridge connecting the charging base station and equipment. The wireless charging system mainly adopts the principle of electromagnetic induction, and realizes the energy transfer through the energy coupling of the coil. Output after the power management modulect, FOD) function under normal circumstances, there is a metal foreign body placed on the transmitter, will not occur fever; Heat occurs when a metal object is placed on the transmitting end and the receiving end is stacked on top. Because the electromagnetic field will generate eddy current on the foreign body of the metal, it will heat the foreign body of the metal, resulting in a dangerous meltdown of the shell.
2, Qi2, is an innovation in the field of wireless charging. Since its inception in 2008, the WPC Wireless Charging Alliance has been committed to promoting the standardization of wireless charging technology worldwide. The Qi2 standard is based on the Q3 protocol and introduces the MPP protocol and magnetic absorptionThe alignment technology, the operating frequency is increased to 360kHz, the foreign body detection function is enhanced, and in MPP and EPP modes, the efficient transmission capacity of 15W is provided, and the future is expected to achieve higher power wireless charging.
3, wireless Qi test includes Compliance Test (Compliance test) and compatibility test (Interoperability Test), the compliance test is conducted by the ATL (Authorized Test Lab), send 5 samples.
4, technical originalIn fact, the Qi charger and the receiving device have built-in conductive coils, and the electromagnetic field generated after the base is energized will promote the coil in the receiving device to be converted into electrical energy, achieving 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. The two main highlights of Qi wireless charging are its convenience and versatility.
1. RecentlyGreen Union launched a popular desktop wireless charger (model CD186), Apple Android universal, support 5W and Apple 5W, Samsung 10W wireless fast charge, the key is the price of only 49 yuan, cost performance can be said to crush the market similar 99 yuan products. In order to understand the workmanship of this product, the next thing to bring you is its unpacking.
1, the use of nuclear magnetic resonance away, in a certain distance, do notData cable can also achieve charging, this I also thought, but earlier had a theory.
1, after a few years, millet 12 released, support 50W wireless fast charge, so millet launched a new Xiaomi wireless car charger Pro, this wireless car charger just support 50W wireless fast charge, can be said to be born for millet 12, after all, the current market support 50W wireless fast charge mobile phone is millet 12In other words, this time Xiaomi wireless car charging Pro or will once again lead the new era of car wireless charging.
2. Yes. The Mi 12 supports wireless charging, and in the Mi 12 and 12Pro phones released in December 2021, 67W/120W wired fast charging and 50W wireless charging are supported respectively. Xiaomi also launched a 50W wireless car charger Pro, which supports three groups of installation methods, arm induction expansion, support for power off and other features, taking full care of the user's experience.
3, millet wireless car charging 50W support millet 13Pro, canTo support the Mi 13Pro fast charging. It supports QC0, QC0, PD0, AFC, FCP, MTK PE0 and other fast charging protocols, which can provide a maximum 50W output power for the Xiaomi 13Pro. It uses a new two-way coil technology, which can effectively improve the charging efficiency, and can be fully charged for the Millet 13Pro in a short time.
4, car wireless charging is suitable for most mobile phones with wireless charging configuration on the market; For example, Huawei Mate RS, Mate20 Pro/RS, P30/P30 Pro, Mi 9/Mix2S/3 and so onMost Samsung series, mobile phones without this configuration can also achieve wireless charging function through wireless charging patches. Recently, Xiaomi launched a smart car charger, Xiaomi wireless car charger Pro, which has been officially launched, which is a small edition of me, but a necessity of life.

Qi wireless charging certification includes the following: 1) membership application; 2) Product registration; 3) Product provision; 4) Product compliance testing; 5) Product compatibility test; 6) Final product confirmation; 7) Review and issue certificates. Qi certification process Wireless charging Qi certification test includes: Compliance test and Interoperability Test.
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: translation measurement in XYZ axisIn the 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.
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.
Qi certification: the universal language of the Wireless charging world Qi, the full name of the Wireless Power Consortium (Wireless Power Consortium, referred to as WPC) masterpiece, it defines a fullUniversal wireless charging standard. This standard is "convenient" and "universal" as the core, ensuring that different brands of products only need to have the Qi logo, can be seamlessly connected with any QI-compatible wireless charger.
