Since 2013, CHANGEN has provided a series of products for global electromagnetic compatibility laboratories, including low dielectric constant support materials (εr ≤ 1.4), optoelectronic transceivers for automotive electronic electromagnetic compatibility testing, full HD shielded cameras, and low dielectric constant test benches, which have been widely welcomed by the market.

Since 2017, based on its existing technical capabilities, CHANGEN has begun to provide testing equipment and solutions for the new energy vehicle industry, including dynamometers, batteries, and charging piles. These include equipment for the production and verification of small actuating motors for vehicles, chassis dynamometers, through-the-wall dynamometers, and testing systems for charging pile products.

CHANGEN has been awarded as a high-tech enterprise for three consecutive times in 2017, 2020, and 2023. In 2016, it was honored with the title of "Guangzhou Little Giant Enterprise in Science and Technology Innovation" and won the "Outstanding Growth Group Award" in the Guangdong division of the China Innovation and Entrepreneurship Competition. In 2017, it passed the intellectual property management system audit and was listed on the Guangzhou Stock Exchange Center. In 2020, it received the title of "Guangdong Province Intellectual Property Demonstration Enterprise". In 2022, it passed the ISO9000 system audit, obtained the four-star brand certification, and was awarded the "Green+ Enterprise" title. Currently, it has been granted 33 domestic invention patents, 5 US patents, 34 utility model patents, 4 trademarks, 1 software copyright, and is in the process of reviewing 22 domestic invention patents and 5 German patents.

Since its establishment, CHANGEN has actively participated in the formulation and revision of standards both domestically and internationally, playing an increasingly important role in standardization organizations. It has actively participated in, spoken at, and submitted proposals for standardization activities both domestically and abroad. It has been awarded the title of Excellent Committee Member multiple times by the Standardization Committee. In addition to participating in national-level standardization organizations, CHANGEN also actively participates in international non-governmental technical organizations, including IEEE, Open Alliance, EtherCAT, etc. It has participated in industry exhibitions abroad, such as in Germany and the United States, introducing Made in China to the world.

Based on CHANGEN's familiarity with equipment and mature system design capabilities, since 2019, CHANGEN has begun to widely adopt domestically produced equipment as the main equipment in system design. A series of domestically produced equipment, including EMI test receivers, RF signal sources, power amplifiers, RF power meters, power analyzers, oscilloscopes, bidirectional DC power supplies, and energy-feedback electronic loads, have been successively integrated into the systems designed for users by CHANGEN.

Meanwhile, CHANGEN Electric Technology has also designed some specialized signal simulation and transmission devices for the new energy vehicle industry, including CP signal, CC signal, PLC signal, CAN signal, and a series of signals for vehicle and charging station use, filling a gap in the market.

CHANGEN will continue to provide global users with instrument-level and system-level "Made in China" solutions, further promoting Chinese manufacturing to the world!
