Oil giants enter the fast charging market, shell 20W Mini charger disassembled

2021-12-27

Royal Dutch Shell Co., Ltd., founded in 1907, is one of the world's leading energy companies and a giant in the automotive oil industry. It is such a company that many people certainly did not expect that it is also related to fast charging, and there are not only chargers but also car charging.

Recently, the charging head network has obtained a shell Mini 20W PD fast charging charger, which is not only compact, but also equipped with national standard pins. It can be seen that it is sold in China. Many people must be curious about how large energy enterprises cross-border fast charging. Let's take a look with Xiaobian.

When equipped with 1a1c interface, the overall size of shell Mini charger is still only 30 * 28 * 28mm, which is very compact and can be regarded as a highlight of the product. Dual port support QC2 0/3.0、AFC、FCP、PD3. 0. The PPS fast charging protocol can not only meet the 20W fast charging of Apple iPhone 12 / 13, but also has good compatibility with Xiaomi, Samsung and other brands of Android.

It is learned from the disassembly of the charging head network that the safety resistance and high-voltage filter electrolytic capacitor on the primary side of the module have been insulated. The classic QR switching power supply architecture is adopted, the synchronous rectification chip adopts jw77186b, the built-in withstand voltage 60V MOSFET, Yongming small volume capacitor for synchronous rectification and output filtering, and the cloud silicon semiconductor xpd738 protocol IC controls the dual port output. In addition to the effective use of internal space by small board stacking, the use of the above devices also helps to realize the miniaturization of the module.
