Oppo announced a new charging technology. Not only fast, the technology introduced at the Oppo Flash Charge Open Day event is claimed to be safer and smarter.
“The development of VOOC Flash Charge technology is based on innovations in fast charging systems that include charging adapters, charging cables, PMICs, batteries, and more,” said Jeff Zhang, Chief Scientist of Oppo VOOC Flash Charge.
"Whether people choose wireless or wired charging, VOOC Flash Charge technology can now meet a wide range of needs when charging electronic devices, even in the most extreme conditions."
1. Safer
Oppo claims to always prioritize efficiency and security in the development of Flash Charge technology. Based on this concept, they have introduced a five -level security protection system to enhance security in VOOC Flash Charge technology, and have explored new materials, AI algorithms, charging architecture and other factors to bring charging innovation further.
Lower impedance fuse
Fuses in the Flash Charge’s five -level safety protection system can explode immediately in the event of a current or other malfunction, protecting the battery by physically isolating it from the mains supply. The improved fuse design has lower internal durability and improved performance, helping to improve the safety of the filling system.
Switzerland Gallium Nitride (GaN)
Oppo has used the GaN switch on its phones for the first time. This switch is not only able to achieve the same function as traditional silicon MOSFET switches in a smaller area, thus reducing the space required, but low impedance and high voltage operation help reduce overheating, improve charging efficiency and reliability.
Two -cell series battery design
The two -cell series battery design allows the same power to be delivered while lowering amperes and reducing overheating. The design of this two -cell series battery goes a step further by incorporating multiple battery cells in the same structure, taking up less space while still providing the same safety performance. The new design allows for at least a 5% increase in battery capacity for the same battery size.
Battery Safety Detection Chip
Battery Safety Detection Chip with AI algorithm can detect if the battery is experiencing external damage by realizing the voltage drop in real time based on various scenarios. If the voltage drop is suspected to be due to damage to the battery, the device will alert the user and take additional safety measures to avoid further danger.
Composite Current Collector
Oppo has developed a battery protector with a new composite structure featuring a composite current collector. The battery uses a new composite material installed between two layers of aluminum to replace the design commonly found on smartphone devices.
This “sandwich” structure is coated with an additional protective material to form a five -layer composite current collector structure to increase battery safety by protecting it from short circuits caused by external damage. Tests at the Oppo Lab show that, without sacrificing performance, the new battery passes puncture and impact tests with a 100%success rate.
2. Smart charging
Oppo also launched a new smart charging technology. The technology adjusts the charging current based on intelligent detection of various charging scenarios that can help reduce the occurrence of battery aging, allowing users to enjoy optimal battery life for a longer period of time.
Smart charging technology is capable of providing significant improvements to various aspects of battery performance, including longer battery life, increased charging speed in certain scenarios, and balancing the charging speed and temperature of the device.
3. Overcharging
Oppo has also been looking for ways to optimize its fast charging technology in more extreme conditions. As of June 30, 2021, OPPO has filed more than 3,000 patents related to fast charging technology. Through more than 30 devices that support VOOC Flash Charge technology,
In 2021, Oppo launched a new project, the Flash Initiative, bringing VOOC’s fast charging technology to automotive, public spaces, and chips included in devices.
