Oppo was one of the first brands to announce proprietary ultra-fast fast charging technology. She was called VOOC and we saw an adaptation of the technology on the OnePlus 3 in the form of Dash Charge, which was limited to 20W. Over the years, the company has worked extensively on VOOC Flash Charge and now we see it on some OnePlus and even Realme smartphones, albeit with different names. We remind you that the three companies are part of the BBK group. The Chinese brand has now announced that it is introducing a new generation of recharge safer and smarter to further exploit the advantages of VOOC.
Here's what's best about Oppo's VOOC charging: a new generation of technology that allows unparalleled safety and efficiency
VOOC Flash Charge it works by using a combination of charging circuitry in the charger which allows for a high current flow and dual cell battery implementation on the smartphone. This is done so that instead of charging a single high capacity battery of around 4000mAh, two 2000mAh batteries are charged in parallel to get better charging speeds. It's not just about speed, though. Oppo has emphasized safety and efficiency with VOOC Flash Charge, and this is the main goal for the future.
To ensure safety when charging at high currents, Oppo has put in place a fivefold safety protection system together with the exploration of new materials, artificial intelligence algorithms. Here are some of the steps that Oppo is taking for make VOOC Flash Charge safer:
- using a fuse with a lower impedance: a lower impedance value means that the fuse blows instantly in the event of a current overload, thus protecting the battery by cutting off power
- use of GaN switches: Oppo uses for the first time GaN switches or gallium nitride in its smartphones, and this is done to reduce the area occupied by a traditional MOSFET switch and to control heat generation
- two-cell design in series: As mentioned above, VOOC Flash Charge uses two cells connected in series. The latest improvement allows for a 5% larger battery while maintaining the same physical footprint
- battery safety detection chip: Oppo uses a custom chip with AI algorithms to detect if the battery has suffered damage or if it behaves abnormally
- composite current collector: The battery uses a new composite material sandwiched between two layers of aluminum which provides a better structure than conventional implementations and prevents short circuits
In addition to these security measures, the brand also talked about make charging technology smarter to optimize both battery life and charging speed. There fast charging affects the health of the battery in the long term, as we know. Oppo is taking the following steps to minimize this effect:
- ensured that using 65W SuperVOOC charging can keep the battery level up to 80% of its original capacity even after 1.500 charging cycles
- charging speeds can be varied according to needs. In short, SuperVOOC can be faster than 20%, allowing you to fully charge a 4500mAh battery in less than 30 minutes
- a new technology has been put in place which balance charging speed and temperature to make the best use of the device while charging
SuperVOOC charging is currently supported on up to 30 devices and Oppo is working to bring this technology to more smartphones. They are also working on standards of wireless charging to speed it up and bring it to the level of wired charging in terms of speed and efficiency. Stay tuned to find out as soon as possible the news regarding the fast charging of the brand.
