This article to talk about wireless charging implementation of what standards, as well as wireless charging industry standards corresponding knowledge points, I hope to help you, do not forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Wireless charger 3C certification standards and what information is required?
No need, the wireless charger belongs to the low-voltage and does not belong to the category of 9 low-voltage products stipulated by 3C, and does not need to do 3C certification, but if your finished product is equipped with an adapter in the box, the adapter needs to pass 3C certification.
Please check that the back of the phone is centered in the center of the wireless charging board. When there are inclusions between the mobile phone and the wireless charging pad, it may not be able to charge normally. Please check the back of the phone. Using a protective phone case that is too thick may hinder wireless chargingIt is recommended to remove the mobile phone cover and try to recharge. Please use the original charger. If you use a non-original charger, you may not be able to charge normally.
Many radio application products, communications products and digital products to enter the U.S. market, all require FCC approval. The FCC Commission investigates and studies the various stages of product safety to find the best way to solve the problem, and the FCC also includes the detection of radio devices, aircraft, and so on.
Under normal circumstances, Apple wireless charging does not need to be set, the charger is connected to the wireless charger with a data cable, and then the phone is placedOn the wireless charge, the phone will show charging. Charging plug please use the original or 3C certified products as electrical products, recommended to use the original plug, one is specially developed for your mobile phone, charging speed is guaranteed, second, safety is guaranteed.
The iphone13 wireless charger is 15W. The iPhone13 supports up to 20W cable charging, MagSafe wireless charging (up to 15 watts), and Qi wireless charging (up to 5 watts).
2, the maximum support of 50 W Huawei wireless Super fast charge, you need to buy Huawei Super fast charge vertical wireless chargingDevice (Max 50 W) or Huawei Super Fast Charger Wireless Car Charger (Max 50 W), and use with a specific 66 W Huawei Super Fast Charging kit.
3, need a wireless charger, iPhone8 and Plus can adapt to all kinds of Qi standard wireless chargers. The built-in 2675mAh large-capacity battery supports the USBPD fast charging protocol using the USB-C interface, and the back uses the glass material to add the wireless charging function. It is equipped with a 5V/1A power adapter model A1443.
4, equipped with 7Inch OLED full screen, in the IEC60529 standard to IP68 level, with black titanium, white titanium, blue titanium and primary titanium four colors, support wireless charging. The iPhone15ProMax has 19 billion transistors, runs the iOS operating system and is equipped with the A17Pro chip. Support focus control and depth of field control, macro photography and other functions. Built-in lithium-ion rechargeable battery supports wireless charging and fast charging.
5, iphonexr can be wireless charging, iphone XR supports Qi wireless charging, but the officialNo wireless charger is given away. If you want to experience the wireless charging function of the iPhone XR, you need to purchase a wireless charger.
Wireless charger principle: electromagnetic induction charging magnetic field resonance charging radio wave charging wireless charger standard: Qi standard; PMA standard; A4WP standard; iNPOFi technical standard.
If you are using a vivo mobile phone, wireless charging is also known as inductive charging or non-contact senseIt should be charged, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
There are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology five. Let's take a look at the principle of wireless charging.
From the theory, wireless charging technology is safe and harmless to the human body, and wireless charging uses the resonance principleIt is magnetic resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmissionMost of the wireless charging uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
1, Qi standard, PMA standard. Qi standard: It has two characteristics of convenience and versatility. Different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger. Cell phones, cameras, computersSuch products can be charged with Qi wireless chargers. PMA standard: Wireless charging standard developed in the United States, with a number of security protection measures.
2, Qi is a Wireless charging standard created by the Wireless Power Consortium (WPC), its biggest feature is based on electromagnetic induction technology, strong compatibility, can realize the charging between different brands, different designs of equipment. In addition, the Qi standard also supports the simultaneous charging of multiple devices, automatic control of charging power and charging protection, which improves the charging efficiency and safety, and brings about charging for peopleConvenient, efficient and reliable experience.
3, the mainstream wireless charging standard Qi standard. Qi is the world's first standardization organization to promote Wireless charging technology - Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard, with convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
4, there are three mainstream wireless charging standards: Power Matters AllThe Power Matters Alliance standard (PMA) has been initiated by Duracell Powermat, a joint venture between P&G and Powermat, a wireless charging technology company. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard.
5, qi2 wireless charging means a new enhanced wireless charging standard. QI2 is usedDon't forget to check it out on this site.
