1. Working principle
The concept of flash charge has been applied to mobile phones and quickly formed a necessary magic weapon for mobile phone brands. However, the concept of flash charge of many domestic mobile phone brands is developed in a disorderly state, and the applicability to voltage and power environment is not perfect. Therefore, vivo has developed dual-engine flash charge technology under the premise of compatibility with international mainstream fast charge protocols, which has higher applicability. More compatible with the power supply environment. Dual engine flash charging technology adopts dual charging chip parallel charging mode, adopts dual charging control chip, dual charging circuit setting, and adopts nine active safety protection measures to ensure the safety of vivo mobile phone in the charging process. vivo dual engine flash charge is to use two intelligent charging circuits, a 'large capacity' multi-cell battery pack for fast charging, that is, the large capacity of a battery is divided into several cells, and at the same time to charge multiple cells, so the charging speed is accelerated, and vivo supports dual engine flash charger models within the range of the battery, will not affect the normal life of the mobile phone.

Step 2: Security
vivo created nine active safety protection measures, including input overvoltage protection, input anti-reverse protection, data line overvoltage protection, input overcurrent protection, input overvoltage protection, temperature protection, reset protection, battery protection, high temperature protection, forming a mobile phone charging the entire chain of security protection, fundamentally solve the mobile phone in the rapid charging of various security risks. At the same time, the mobile phone has also joined the intelligent protection route, that is, the intelligent balanced charging mode, which is called \"charging nanny\" in the balanced charger. This system can effectively protect the battery cell, prevent over-charging and over-discharging, and extend the battery life and battery durability.

3. Energy-saving engine collocation
vivo has also developed another set of energy saving engine, ECO energy saving engine, multi-directional for mobile phone battery life to provide a steady stream of technology, this energy-saving engine, effectively reduce large applications, control heat. The ECO energy saving engine is another major innovation of the dual-engine flash charge, which improves the battery life of the phone by actively scanning for the power-consuming applications of the phone, shutting down the background applications with high power consumption and low frequency of use. At the same time, the ECO energy saving engine also has an intelligent power saving management system, which will save energy for the common applications of the mobile phone, so that the mobile phone has been in a state of low consumption and high efficiency. Improved battery life and battery life of the phone.

4. Charging test
vivo dual engine flash charge using dual charging chip, compared with the traditional charging system, adds a charging chip, increases the intelligent distribution in the charging process, but also adds a charging circuit, thus forming a double ring intelligent charging control system, in theory, double engine flash charge, in the use of the original charger theoretically has twice the charging speed of ordinary mobile phones. In the actual test, 0-60% only takes 40 minutes, 0-100% charging time as long as 89 minutes, which is a very ideal result. At the same time for the charge and discharge test of lithium batteries, the national standard for charge and discharge 500 times, the battery capacity should be more than 80% of the qualified, in vivo dual-engine flash charging technology, after 500 charge and discharge, the battery capacity can be maintained at more than 90%.
