This way you can charge your phone up to 1500 times, your battery will still be okay
Oppo introduced a new generation of intelligent, fast charging technology. The company’s researchers are primarily looking at how new materials, modern charging architectures and artificial intelligence-based algorithms can be used to enhance charging performance and make charging batteries even safer.
Oppo claims its latest developments can effectively increase charging speeds while a new safety system prevents battery damage. The system consists of five components: improved fuses, gallium nitride (GaN) switches, a special two-cell battery, a safety chip, and composite pantographs for batteries.
In the event of low impedance fuse overload or other symptoms in flash charge, it immediately disconnects the battery from the power supply to physically protect it from damage. The improved fuse has a lower internal resistance, which makes the charging system even safer, the company said in a statement.
For the first time, Oppo uses gallium nitride (GaN) switches on its smartphones, which perform the same function in a smaller area as conventional silicon switches (MOSFET) and reduce heat production, improving charging efficiency and reliability.
Two-cell batteries allow for a non-fluctuation power supply while reducing voltage and heat generation.
The smart chip of a battery that uses AI algorithms can detect voltage outages in real-time. If the battery’s voltage drop is caused by damage, the phone will alert the user and initiate additional preventive safety measures.
Oppo’s new safety battery features a composite pantograph, replacing typical aluminium-only solutions. The five-layer pantograph with a “sandwich” structure is coated with additional protective material that protects the battery from short circuits caused by external damage. According to Oppo Lab test results, the new battery performs 100 per cent successfully in puncture and impact tests.
Intelligent charging, extreme conditions
The company said that artificial intelligence could improve battery performance in several areas, both by increasing battery life and, in some cases, by achieving better charging speeds. The new technology, developed by engineers at the Chinese company, can maintain up to 80 per cent of the battery’s original capacity after up to 1,500 charging cycles using the 65W SuperVOOC fast charging.
The new technology allows for a 65W SuperVOOC fast charging speed to reduce charging time by about 20 per cent, making a 4,500 mAh battery chargeable in as much as 30 minutes. The technology is also capable of controlling charging power depending on the battery temperature. As a result, the company promises that users can use their phones while charging without any heat-related inconvenience.
The company’s fast charging technology delivers optimal charging performance even at shallow temperatures: test results show that between -20°C and 10°C, the battery temperature can reach the ideal range in less than a minute, allowing the battery to charge normally.
