Recently Xiaomi released 200W wired charging and 120W wireless charging technology，Let the mobile phone charge time be within 8 minutes。Zhitiao, as a few industry media, was invited to have in-depth exchanges with Xiaomi fast charging engineers.。 Engineers related to Xiaomi's fast charging technology analyzed the charging technology released by Xiaomi this time in a deeper way，Including charging devices、Battery Materials、Adjustment of charging algorithm and architecture、optimization，And he also made his own judgment on the future development of fast charging technology。 one、大功率充電和輕薄真的不可兼得嗎？ 快充、High power、Flirtatiousness always seems to be a contradictory existence，And the trade-offs between them，You can also see what kind of user experience a manufacturer focuses on。Lei Jun and Xiaomi engineers agree that charging、battery life、The three aspects of lightness and thinness are all three very important dimensions of mobile phones。 Lei Jun once mentioned，The charging speed and the energy density of the battery cannot be used at the same time.，In order to achieve a relatively balance between speed and lightness, Xiaomi，The energy density of the 10C battery is achieved to the extreme，Minimize the impact of "reduced energy density caused by fast charging" as much as possible。 Xiaomi engineer said，Although the word "light" is simple，But the requirements for engineers are very high，Such high-power fast charging technology stacks onto a thin and light phone，Need to get a battery、cooling、All stacked，This presents a more stringent challenge to all engineers and experts，Xiaomi has a dedicated team to do the ultimate stacking design。 Talking about lightness，Just talk about battery life，This demonstration machine has a thickness of about 9mm and a 4000mAh battery，Obviously there is still a lot of room for improvement。 Xiaomi engineer said，Xiaomi has its own battery life and DOU model，A lot of effort has been made to optimize the battery life of each machine。 Except for the thinness of the phone，The portability of the charger is also important。Xiaomi engineer said，Through the new gallium nitride technology，The switching frequency is twice as high as 120W，Many energy storage devices can be used with smaller ones。…

小米公司官微6月11日發微博稱，上週徵集了米粉關於小米200W有線&120W無線充電技術的一些問題，And invited a representative of Mi Fan to ask Xiaomi engineers in person。小米公司官微還通過8 張圖對200W 有線&120W 無線充電技術的安全及技术進行了釋疑。
