China establishes its first-ever fast-charging association


200 W charging

Fast-charging is now a must-have for most mobile phones and smart devices. However, because fast-charging chargers do not use the same technology or provide the same power, there are a lot of standards in the current market. Simply put, different brands have different standards. There is no effective identification between the terminal and the charger. Thus, in many cases, users end up with low-charging power because they don’t have original chargers.

According to Chinese media reports, the Guangdong Terminal Industry Association was established in Shenzhen a few days ago. It was initiated in early 2021 by the Information and Communications Institute. This association has Chinese mobile phone manufacturers and leading companies as members. From the list of members, we have the likes of Huawei, Xiaomi, Oppo, Vivo, Honor, and other companies.

The Guangdong Terminal Fast-Charging Industry Association will coordinate and integrate industrial resources to promote standardization. It will also promote the industrial application of charging technology. This is the first electronic consumer terminal fast charging association in China.

The establishment of the terminal fast-charging association not only accelerates the standardization of fast charging technology but also hopes to reduce electronic waste and energy waste. As of now, there is no information on whether the association will set up a unified standard. Nevertheless, the establishment of the association means that Chinese fast charging and data lines will be unified. After the unification, all brands charging can work for each other.

150W fast-charging is about to start mass production

The charging power for smartphones is consistently increasing and smartphones can now get a full charge in less than 15 minutes. Today, Weibo tech blogger, @DCS, claims that 150W fast charging for smartphones is on its way. According to him, this fast charging technology will enter mass production very soon. Unfortunately, he did not reveal the manufacturer that will launch this technology.

150W fast charging

Presently, the smartphone industry has 120W fast charging which can deliver a full charge in only 15 minutes. This is for a 4200 mAh – 4500 mAh battery. Xiaomi Mi 10 Ultra and iQOO 5 Pro hold the record as the first smartphones to use the latest 120W fast charging. However, the Xiaomi Mi 10 Ultra’s actual charging power seems to be lower than the advertised 120W charging.

Taking the iQOO 5 Pro as an example, to achieve ultra-high-power fast charging, iQOO uses a charge pump half-voltage scheme. This can make the voltage entering the battery half of the charger voltage, and convert the high-voltage and low-current of the AC power into the low-voltage and high-voltage required by the battery. This configuration significantly increases the overall charging speed.
