OPPO Introduces a New Generation of Safer, Smarter Flash Charging Technology

Leading global smart device brand OPPO held its “What’s Next for Flash Charging?” OPPO Flash Charge Open Day recently, during which it unveiled the most recent achievements from its ongoing research into fast charge technology.

“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.”

OPPO has always placed efficiency and safety at the forefront of its development of Flash Charge technology. Based on this concept, OPPO has introduced a five-fold safety protection system to improve safety in VOOC Flash Charge technology, and has been exploring how new materials, AI algorithms, charging architectures and other factors can be used to deliver further innovations.

The fuse contained in the Flash Charge five-fold safety protection system is able to immediately blow in the case of an electric current overload or other abnormality while the Gallium Nitride (GaN) switches offer greater speed and reliability when compared to traditional silicone switches.

A-series bi-cell battery design allows the same power to be delivered while lowering the electrical current and reducing heat generation. OPPO’s proprietary Battery Safety Detection Chip with embedded AI algorithms is able to detect if batteries have suffered from external damage by recognizing voltage drops in real-time. OPPO has developed a Composite Structure Safety Battery featuring an all-new composite current collector.

Smart charging: optimizing speed and battery life for the perfect balance

OPPO also 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 charging speed can be increased according to specific situations based on the instantaneous maximum power that the battery can safely take in at any given time.In addition to making VOOC Flash Charge as safe and smart as possible, OPPO has also been exploring ways to optimize fast charge technology under more extreme situations such as very cold environments.

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. 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.
