Oppo introduces SuperVOOC 150W charger and battery recovery technology

  • February 28, 2022

Just a few days ago, Oppo unveiled the flagship Find X5 duo, which supports the new 80W SuperVOOC. Today at the MWC presentation, the company announced what’s coming next, an upgraded system that nearly doubles the power.

In a lab test, the upcoming 150W SuperVOOC system charged a prototype phone with a 4,500mAh battery from 1% to 50% in just 5 minutes and reached 100% in a total of 15 minutes (this was with the device on but inactive and in flight mode). By comparison, an older 65 watt charger takes about 40 minutes to ramp up to 100%.

The new system uses a 150-watt SuperVOOC charger. Thanks to GaN technology, the charger measures 58 x 57 x 30 mm and weighs 172 g. That’s not much more than the old Oppo SuperVOOC 65W adapter. It also means that the adapter’s power density is 1.51 watts/cm³, which is much higher than that of a conventional charger.

Although VOOC technology is patented (1,786 issued patents and 1,604 patents pending), the new charger supports the standard USB Power Delivery and PPS protocols used in phones, laptops and other gadgets.

At any rate, the charger delivers 7.5A at 20V. Inside the phone are two battery cells, each with its own charging pump, which converts the incoming electricity to 5 V / 15 A and feeds it into the battery.

Oppo has solved the battery life problems in two ways. The first is the Battery Health Engine, which uses a special chip to control the battery. In lab tests, the battery retained 80% of its capacity after 1,600 full charging cycles (twice the industry average of 800 cycles).

This is partly due to the Smart Battery Health algorithm, which constantly monitors the negative electrode to minimize the appearance of dead lithium – lithium ions that get trapped and cannot carry a charge (lithium loss thus reduces battery capacity). The Oppo Find X5 series already features the Battery Health Engine.

Battery Healing technology solves another problem. The battery design that Oppo uses includes a solid electrolyte interface (SEI), a tough film on the battery electrodes that protects them from degradation. Battery recovery here refers to a special electrolyte formula that continuously regenerates the SEI layer while the battery is charging and discharging. This keeps the electrodes in good condition, which improves battery performance and prolongs battery life.

The first phone to use the 150-watt charging system will be the OnePlus device, which will arrive in April-June. The company said it is working on improving SuperVOOC to support charging speeds of 200 watts or higher.
