Qualcomm QC3.0 certification

Quick Charge technology introduction


Introduction to Quick Charge 2.0 technology
The so-called QC2.0 technology is actually a fast charging solution for mobile phones combined with Qualcomm's Snapdragon 800 series chipset. It will be based on the Quick Charge2.0 or QC2.0 protocol and can adapt to 5V, 9V or 12V wall charger Quickly charge mobile devices such as mobile phones that support the Quick Charge 2.0 protocol. The working principle of QC2.0 fast charging technology is to increase the output voltage under the condition of the charging current limit, thereby further increasing the charging power and greatly reducing the charging time. It is divided into two industry standards: A and B. A standard: 5V, 9V and 12V output voltage, B standard: 5V, 9V, 12V and 20V output voltage.

Introduction to Quick Charge 3.0 technology

After the popularization of Quick Charge 2.0, Qualcomm announced 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 uses the Intelligent Negotiation for Optimum Voltage (INOV) algorithm in similar products. INOV is a new algorithm developed by Qualcomm Technologies, designed to help portable devices have the ability to select the required power level to achieve good power transmission at any time and maximize efficiency. Quick Charge 3.0 uses the "Intelligent Negotiation for Optimum Voltage (INOV)" algorithm for the first time, which can achieve good power transmission at any time and maximize efficiency.
Quick Charge 3.0 can charge an ordinary mobile phone from zero power to 80% in about 35 minutes. Traditional mobile terminals without Quick Charge usually take about one and a half hours. Compared with the previous generation, with INOV and other advanced technologies, Quick Charge 3.0 can achieve a 38% efficiency improvement over Quick Charge 2.0, while also adopting other methods to help protect the battery life cycle.
