First, the introduction of Quick Charge 2.0 technology
The
so-called QC2.0 technology, in fact, is a combination of high-pass Xiao
Long 800 series chipset's latest mobile phone fast charging program,
based on Quick Charge 2.0 that QC2.0 protocol can be adaptive output 5V,
9V or 12V wall charger Quickly charge mobile devices such as mobile phones that support the Quick Charge 2.0 protocol. QC2.0
fast charging technology works in the case of charge current limit to
increase the output voltage, and then the maximum charge power to
further increase, making the charging time is greatly reduced. And divided into A and B-class two industry standards. A standard: 5V, 9V and 12V output voltage, B standard: 5V, 9V, 12V and 20V output voltage.
Second, Quick Charge 3.0 technology introduction
After
Quick Charge 2.0 is gaining popularity, Qualcomm announces the launch
of its next-generation fast charging technology, Qualcomm-Quick Charge
3.0. As
the third generation of fast charging technology, Quick Charge 3.0 is
the first to use the Intelligent Negotiation for Optimum Voltage (INOV)
algorithm in its class. INOV
is a new algorithm developed by Qualcomm Technologies designed to help
portable devices have the ability to select the required power levels to
achieve good power transfer at any time and to maximize efficiency. Quick Charge 3.0 for the first time using the "Intelligent Negotiation
for Optimum Voltage (INOV) algorithm, at any time to achieve good power
transmission, and maximize the efficiency. Quick
Charge 3.0 can charge an ordinary handset from zero charge to 80% in
about 35 minutes, and traditional mobile terminals that do not have
Quick Charge usually take approximately one and a half hours. Compared with the previous generation, with the help of INOV and other
advanced technology Quick Charge 3.0, can achieve more than Quick
Charge 2.0 up to 38% efficiency, while also using other methods to help
protect the battery life cycle. Third, QC3.0 certification / QC2.0 certification applicable to the product range
Provide energy products (in-line charger, car charger, mobile power,
etc.), mobile phones, tablet, notebook and other end products do not
belong to its scope.
Fourth, QC3.0 certification / QC2.0 certification process
1, signed a contract 2, submit samples, sample information and documentation 3, audit assessment information 4, product testing 5, audit report 6, Qualcomm authorization 7, get the certificate 8, listing
Fifth, QC certification need to prepare the information
1, test samples more than 2 2, component list (BOM) 3, PCB board wiring diagram (LAYOUT) 4, sample schematics, brochures 5, label 6, fill out the application form Note: specific information according to product specifications to confirm.
Sixth, QC3.0 certification / QC2.0 certification on the role and significance of enterprises
1, certified products can be bulk purchase Qualcomm fast charge IC, charging efficiency increased by 40% -75%; 2, allowing the use of QC3.0 LOGO, enhance the brand influence, competitiveness; 3,
in the world has been calling for energy-saving emission reduction
environment, such enterprises and products will be more social and
consumer recognition.
