At present, China's integration and fast charging work has achieved certain results, but still faces huge challenges. The integration of fast charging industry should pay attention to the formulation of standards. Strengthening the promotion and implementation of standards and certification, improving the strength of technology research and development, and mastering the interface and fast charging technology are effective ways to promote the unification of fast charging equipment in China. ——Liang Yutong, Secretary-General of Guangdong Connector Association, and Deputy Secretary-General of Guangdong Wire and Cable Industry Association, Apple 15 (iPhone15) or the information with USB-C charging interface will go on the hot search again. At present, there are two mainstream charging interfaces in the world. Android platform has basically completed the unification of USB-C interface, and Apple is the only mobile phone brand that insists on using Lightning interface. Is the global unified charging interface feasible? Does the unified charging interface mean that we can use one charging head and one charging cable to solve the problem of fast charging (hereinafter referred to as fast charging) of all mobile intelligent devices? How far do we have to go to achieve this goal? On March 1, the reporter of Science and Technology Daily interviewed relevant experts. The small interface set off a "storm" in the accessory market. In October 2022, the European Council approved the bill of "unified charging interface in the EU", stipulating that mobile phones, tablets, digital cameras and other electronic devices sold in the EU since 2024 must use the USB-C interface uniformly. "According to the new regulations of the European Union, Apple Lightning interface will no longer be applicable to the electronic equipment market in the European Union." Xiang Ligang, chairman of the Zhongguancun Information Consumption Alliance, told Sci-Tech Daily that the change of the iPhone 15 interface means that Apple's mobile phone will be further transformed into a universal one. However, it is not ruled out that the iPhone 15 series, which may be released this fall, will launch the "EU Special Edition" product, or avoid the interface restrictions by accelerating the wireless charging. Xiang Ligang said that the unified charging interface is USB-C, which will reduce thousands of tons of electronic waste every year and promote the reuse of chargers. Liang Yutong, Secretary-General of Guangdong Connector Association and Deputy Secretary-General of Guangdong Wire and Cable Industry Association, said that compared with USB-C interface, Apple Lightning interface has some outstanding problems, such as slow transmission rate, unsatisfactory fast charging speed and poor equipment compatibility. Since its launch in 2015, USB-C has become the preferred interface for global mainstream mobile phones, consumer electronics, personal computers and other manufacturers. It has the advantages of small size, positive and negative insertion, fast transmission, strong signal capability, and good compatibility. Specifically, although Apple Lightning connector supports forward and reverse insertion, only 8 pins work, and the maximum current it can withstand is only 3 amperes (A), and the upper limit of charging power is 33 watts (W). At present, the Gallium Nitride Charger, which is popular in the market, has a charging power of 40-120W. Liang Yutong said that the charging interface of mobile devices is not uniform, which first brings trouble and inconvenience to consumers. Secondly, because Apple Lightning interface data line standard is not open, enterprises can only produce under the authorization of Apple. The production enterprise has low autonomy, and the product
