如何實現智慧型手機的快速充電?

本視頻介紹了手機快速充電背後的技術，從早期的線性充電器的手機到最先進的大功率 Direct-Charge-Divide / 2 系統。我們討論了不同的電池類型，特殊充電系統（例如高通公司的 Quick-Charge QC2.0 / 3.0）和新的 USB-C Power Delivery 充電系統，涵蓋了 Direct Charge 和 Direct Charge-Divide / 2 系統，可以提供高達 45W 的充電功率而不會造成過熱。我們利用示波器和 USB-PD 分析儀連接至 Galaxy Note 10+ 等不同的智慧型手機，以詳細檢查其充電行為。最後我們還會向您介紹下一代智慧型手機充電技術，例如 Direct Charge-Divide / 4 和雙電池系統。
