In recent years, new energy vehicles have developed rapidly and become popular, but the accompanying "range anxiety" has also troubled the majority of car owners. So, portable charging guns that can be carried around and used to charge your "love car" as long as there is a standard socket have entered consumers' sight.

Mode 2 portable charging gun, as a plug and play charging device, has a simple structure and simple operation, and is not limited by the charging site, meeting the application requirements of electric vehicle owners for charging at any time. In addition, Mode 2 portable charging box has stable performance during use, and compared to Mode 1 unprotected charging, Mode 2 charging is safe and guaranteed.

Sihao was founded on April 24, 2018. This brand is a new brand launched by Volkswagen (Anhui) Co., Ltd. (formerly known as Jianghuai Volkswagen Co., Ltd.), a joint venture between Anhui Jianghuai Automobile Group Co., Ltd. and Volkswagen Group (China). It is also one of the subsidiary brands of Volkswagen.

By disassembling the portable charging gun of Sihao New Energy Vehicle, we found that Wuhan Core Source Semiconductor's CW32F030C8T6 serves as the core control chip.

As the core component of the charging gun, it not only requires safe and reliable charging, but also needs to adapt to various usage environments from extremely cold in Northeast China to extremely hot in Sanya. This requires extremely high requirements for the MCU, indicating that the CW32F030C8T6 microcontroller of Wuhan Core Source Semiconductor has been recognized by frontline host manufacturers.

The CW32F030C8T6 of Wuhan Core Source Semiconductor supports an ultra wide temperature range of -40~105 ℃, and there are also publicly available test results such as HBM ESD 8KV and EFT 4KV. All ESD and Latch Up indicators meet the highest international standards, ensuring the safe and stable operation of the charging gun.
