Leading global smart device brand OPPO recently held its “What’s Next for Flash Charging?” OPPO Flash Charge Open Day on July 22, during which it unveiled the most recent achievements from its ongoing research into fast charge technology and the development of its Flash Charge technology solution.
“OPPO’s development of its VOOC Flash Charge technology is based on innovation across an entire fast charging system that encompasses the charging adapter, charging cable, PMIC, battery and more,” said Jeff Zhang, Chief Scientist of OPPO VOOC Flash Charge. “Whether people choose wireless or wired charging, VOOC Flash Charge technology is now capable of meeting a wide range of needs when it comes to charging electronic devices, even in the most extreme circumstances.”
Safe charging: new upgrades and innovations create a safer charging experience
OPPO has placed efficiency and safety at the forefront of its development of Flash Charge technology. Based on this concept, the company has introduced a five-fold safety protection system to improve safety in VOOC Flash Charge technology, including fuse with lower impedance, Gallium nitride (GaN) switches, internal series bi-cell design, battery safety detection chip, and composite current collector. The company has been exploring how new materials, AI algorithms, charging architectures and other factors can be used to deliver further innovations.
Smart charging: optimizing speed and battery life for the perfect balance
OPPO unveiled its new smart charging technology during the event. Designed to keep the charging speed within the safest possible range, the technology adjusts the charging current based on intelligent detection of different charging scenarios.
The smart charging technology can deliver noticeable improvements to multiple aspects of the battery’s performance, including longer battery life, improved charging speed in specific scenarios, balancing charging speed and phone temperature.
Extreme charging: even in the coldest environments, Flash Charge doesn’t give up
In addition to making VOOC Flash Charge as safe and smart as possible, OPPO has optimized fast charge technology under more extreme situations. OPPO’s ultra-low temperature charging solution uses smart algorithms to determine the optimal charging temperature of the battery and increase the temperature before charging begins. Test results show that the battery can increasing in temperature from -20℃ to 10℃ in just tens of seconds, allowing the battery to be charged as normal.
From the introduction of VOOC Flash Charge in 2014, safety, efficiency, and ease-of-use have been three of the core areas that contribute to OPPO’s R&D into battery and charging technology. As of June 30, 2021, OPPO has already applied for over 3,000 patents related to fast charge technology; and through over 30 devices that support VOOC Flash Charge technology, the company has brought this fast, convenient, and safe charging experience to more than 195 million people worldwide.
In 2021, OPPO launched its new project – The Flash Initiative – bringing its proprietary VOOC technology to automobiles, public spaces, and chips inside a wide variety of devices. In the era of the Internet of Experience, OPPO’s Flash Charge technology is evolving to bring users a new generation charging experience designed to excel in any situation, allowing people to charge any device, anytime, anywhere.
