qi pronounced "chee" Its name has its roots in Asian philosophy and means "key energy", an invisible energy. After Apple joined the WPC Wireless Power Alliance, wireless charging has become more and more popular, and Qi certification has also received more and more attention. WPC is the world's first standardization organization (Wireless Power Consortium) to promote wireless charging technology, and the wireless charging standard has two characteristics: portability and universality. Qi is an open universal standard that can be used with any Qi device, so consumers don't need to use separate chargers, cables, and adapters, and can safely and easily charge wirelessly at home, office, station, wine***, and more. Products powered by Qi technology must undergo rigorous testing to guarantee safety, interoperability, and energy efficiency. Only products that pass these independent laboratory tests can use the QI mark and are considered QI certified. Products using the QI standard must undergo rigorous testing to guarantee their safety, interoperability, and energy efficiency. The QI mark can only be used for products that have passed independent laboratory testing and are considered "QI certified" products.
1. Products that have not been tested and certified have potential safety hazards, such as heat, burns, and disasters
2. It is difficult to sell in European or American retailers, and now retailers are aware of the risks and trust certified products more;
3. WPC will spot check, if there is no certification and marked with the certification mark, the WPC spot check will give corresponding penalties;
4. After Qi certification, you can put on the logo and find the certificate on the WPC official website to bring brand effect.
QI Authentication Steps:
1. Join WPC as a member (customer operation).
2. Submit an application for testing requirements.
3. The laboratory accepts applications.
4. The laboratory conducts compliance tests.
5. Application for interoperability test.
6. Interoperability testing.
7. Issue QI certificates.
8. Product registration (customer operation) in WPC
QI certification application materials:
1. Five samples need to be marked with the charging point of each sample.
2. If there is testing auxiliary equipment, at least 3 sets need to be provided.
3. Product instruction manual and operation guide.
4. Self-declaration form.
5. **Test data.
Qi Certification Registration Notes:
1. Similar products (no testing required) means that the products that need to be certified are the same as the products that have passed the previous Qi certification. For example: - Change the color of the product - Change the brand name.
2. Products containing registered subsystems (no testing required) subsystems refer to transmitter products with complete functions, coils, protective layer shielding, and assembly with control systems. Without any additional assembly or assembly, it can be directly operated and tested. For example, the charging module installed on the table is embedded in the table with QI certification, and the table can be registered directly.
Who can apply for QI certification:
1. Only WPC members can (once the company withdraws from WPC, the product will also be removed from the QI certified product library);
2. Only companies that have signed the QI mark license agreement (QI mark is a registered trademark) QI certification covers all electronic products with wireless charging function, and both the transmitter and receiver need to be certified.
QI Authentication Type:
1) QI-BPP Certification:
The product supports power less than 5W, uses the QI protocol, and must pass BPP certification.
2) QI-EPP Certification:
The product supports more than 5W power, uses the QI protocol, and must pass EPP certification.
3) QI-PPDE certification.
The product supports more than 5W power, uses Samsung's private protocol PPDE, and must pass BPP certification + PPDE test (implemented from July 1, 2019).
Qi Certification Product Category:
1) By coil type:
Single coil: A11, A11;
Multicoil: A28;
2) According to the commonly used products, it is divided into:
Charger products;
Power Bank Products;
Embedded devices (TX transmitter function is included in the product).
