OPPO Launches Multiple Charge Technologies

OPPO announced two breakthroughs in high-speed flash charging: 150W SUPERVOOC with Battery Health Engine (BHE) and 240W SUPERVOOC flash charge technology. The Chinese vendor has integrated its self-developed BHE within the ultra-fast 150W SUPERVOOC flash charge, allowing the battery to maintain 80% of its original capacity after as many as 1,600 charge cycles, double the current industry standard, thus providing extremely fast charging in addition to the battery’s health protection. 240W SUPERVOOC flash charge technology marks the latest technological breakthrough in the mobile phone industry. Charging a 4,500mAh battery from 1% to 100% in about 9 minutes, 240W SUPERVOOC kicks off a new era of safe and efficient flash charging.

“As charging science continues to develop at an ever-increasing pace, users’ expectations are responding accordingly. Since the launch of VOOC flash charge in 2014, OPPO has prioritized the overall charging experience while leading the development of flash charge technologies. We will continue to push the limits of high-power flash charge technologies, actively tackling emerging issues such as the deterioration of battery health, and providing users with safe, efficient, smart, and fast charging solutions that go beyond speed,“ said Jeff Zhang, Chief Charging Technology Scientist at OPPO.

Evolving from 125W SUPERVOOC flash charge technology, 150W SUPERVOOC flash charge with BHE uses direct charging technology with two charge pumps which can support up to 20V/7.5A charging. In addition, the adapter for 150W SUPERVOOC with BHE leverages gallium nitride (GaN) to reduce the size of the adapter to nearly the same size as the previous generation 65W SUPERVOOC adapter, measuring 58 x 57 x 30mm, and weighing around 172g. To improve the all-around charging experience, 150W SUPERVOOC flash charge features the Battery Health Engine, which is powered by OPPO’s customized battery management chip and includes two key technologies: Smart Battery Health Algorithm and Battery Healing Technology. Together, they improve battery health, safety, and performance by optimizing the hardware and software.

Smart Battery Health Algorithm can track real-time electric potential across the negative electrodes inside the battery. It dynamically adjusts the charging currency within a reasonable range, effectively minimizing the occurrence of dead lithium while maintaining the maximum charging current. This helps ensure prolonged battery lifespan and faster-charging speeds. Battery Healing Technology optimizes battery life from the inner system of the battery. By improving the electrolyte formula, the electrodes are continuously repaired during the battery’s charge and discharge cycles, forming a more stable and durable solid electrolyte interface (SEI) that always stays in a perfect state in real-time. This helps in reducing the wear and tear of the positive and negative electrodes of the battery, therefore, enhancing battery performance and extending battery lifespan.

Due to the growing demand for high-efficiency charging solutions in the era of 5G intelligent connectivity, OPPO has further pushed the limits of high-power flash charge and launched 240W SUPERVOOC. This new technology can charge a 4500mAh battery to 100% in about 9 minutes. 240W SUPERVOOC is designed with 24V/10A technology on the Type-C interface. It boasts three charge pumps and the power supplied to the handsets can be converted to 10V/24A. It conforms to the existing device specifications and has been tested in terms of heat dissipation, guaranteeing optimal efficiency and enhanced safety. Furthermore, the battery’s leading discharge rating allows the hardware to support a maximum of 240W.
