OPPO 65W SuperVOOC 2.0
SuperVOOC 2.0 is based on SuperVOOC technology platform and is designed with series double cores. When discharging, the voltage of double cores can be halved by using a charge pump. SuperVOOC 2.0 can fill a mobile phone with a 4000mAh battery in less than 30 minutes.
In the whole link charging management process, SuperVOOC 2.0 uses a number of custom chips, including VCU intelligent control chip, AC/DC control current and voltage; MCU charging management chip, BMS battery management chip, custom protocol handshake chip, from adapter to charging line to mobile phone, the three together form the charging protocol closed loop of SuperVOOC.
On the adapter side, the SuperVOOC 2.0 adapter uses the third generation semiconductor, GaN gallium nitride. The most significant advantage of gallium nitride is that it can improve charging efficiency and achieve smaller charger size at the same time. At the same time, OPPO will be the first mobile phone brand to use gallium nitride, and the OPPO Reno Ace10 is released for the first time in the month.
OPPO 30W Wireless VOOC Flash charge
At the communication meeting, OPPO also released a new 30W wireless VOOC flash charge, which can charge the equivalent 4000mAh battery energy to 100% in 80 minutes, is compatible with the QI standard, and supports 5W and 10W charging power.
The 30W wireless VOOC flash charge adopts real-time communication adjustment, matches the wireless charging board for constant voltage and constant current direct charging, and integrates the VOOC isolated charge pump technology pioneered by OPPO, so that the electricity can be charged into the battery more efficiently and safely.
In terms of safety, 30W wireless VOOC flash charge adds soft switching scheme and DC isolation scheme, DC isolation scheme can effectively block the potential high voltage DC current circuit, so as to avoid the safety risks caused by high voltage current applied to the battery. The 30W wireless VOOC flash charge also adds the foreign body detection function, when the charging plate detects the metal foreign body, can stop charging immediately.
Officials say OPPO's 30W wireless VOOC flash charge is comparable to the VOOC 1.0 flash charging experience, has a very good heat control performance, and the highest temperature during charging will not exceed 40 degrees. The technology is expected to be commercially available in the first half of 2020.
OPPO 30W VOOC 4.0
In addition to bringing 65W SuperVOOC 2.0 and 30W wireless VOOC flash charging, VOOC flash charging has also evolved to version 4.0, which has higher charging power than VOOC 3.0.
Officials say the 4000mAh battery can be charged to 67% in 30 minutes and 100% in 73 minutes, 12% less than the previous technology. At the same time, the further optimized VFC algorithm also reduces the charging time required for the last 10% of the power. In addition, VOOC 4.0 reduces the internal resistance of the entire charging system hardware by customizing the 30W high power version adapter and using 3C cells.
VOOC 4.0 has good compatibility and is compatible with all flash charging protocols prior to VOOC 3.0 to obtain full charge power for 5V4A (20W). In addition, VOOC 4.0 will launch the OPPO K5 in October.
