The international product safety testing and certification agency UL (Underwriters Laboratories) awarded the world â€™s first electric vehicle charging technology evaluation laboratory accreditation certificate based on the SAE J1772 standard to the Taiwan Electric Power Research and Test Center, and the world â€™s first SAE J1772 The evaluation system recognized the certificate to Zhimao Electronics. Through the internationally recognized UL evaluation certification, the world â€™s first third-party testing laboratory to perform electric vehicle charging technology verification is expected to start Taiwan â€™s technical expertise and testing energy in the electric vehicle charging interface, and help Taiwanese companies develop while taking into account. Products of domestic and global market specifications are in line with the world.
At present, the national standard for electric vehicle charging technology in Taiwan has not yet been finalized. However, in order to ensure that the demonstration operation of electric vehicles in various counties and cities can be successfully promoted, the domestic charging interface technology standard SAE J1772 communication agreement is used as the basis for evaluation. SAE J1772 is an international standard setting organization-the Society of AutomoTIve Engineer (SAE), a technical specification proposed and continuously revised in 2001, which specifies low-voltage conductive charging interface specifications, including hardware Mechanical and electrical requirements, and communication agreements between charging systems and electric vehicles.
The SAE J1772 standard was first adopted by the California government of the United States as a unified interface specification for electric vehicle operation subsidies in the state, and later became a common standard interface in North America. It was then adopted by the international IEC standard and became unified by IEC member countries. interface. In October this year, SAE J1772 revised the standard specifications for the DC fast charging system, and was recognized by most countries in the world. It became one of the international general standards for the fast charging and composite interface (Combo) of electric vehicles in the future.
Tang Jiade, general manager of UL Taiwan, said: "At present, SAE J1772 is the main standard for electric vehicle charging interfaces in Europe and the United States. Although there are clear specifications, the practical practices in testing and verification are still not unified. At this stage, each car manufacturer In order to ensure the compatibility between their own vehicles and different charging stations, each charging module must be paired with different charging station modules for one-to-one testing; similarly, charging system operators must also carry out their own charging stations Pairing tests of different car manufacturers and car models. This approach not only cannot ensure the representativeness of the test results, but also the test time and cost will continue to rise with the different car models and the increase in charging station models.
In order to solve the problem of interface compatibility, the government decided to adopt SAE J1772 as the technical standard interface for the demonstration operation of electric vehicles in Taiwan. At the end of last year, it commissioned the Taiwan Electric Power Research and Test Center as a local demonstration verification center, and invited the international certification unit UL According to the standard spirit of SAE J1772, a set of standardized verification procedures was established. Together with the SAE J1772 automated evaluation system designed by Zhimao Electronics, UL completed all the functional evaluations in October this year, becoming the world â€™s first third Fang testing laboratory.
In the future, in addition to Taiwan's ability to self-evaluate interface compatibility in accordance with the SAE J1772 communication protocol, since the charging system involves high voltage and high current safety issues, UL will be able to conduct safety assessments on safety. The requirements for charging status and technical specifications specified in SAE J1772 are evaluated using UL 2231 (personal protection), UL 2202 (DC charging system), UL 2594 (AC charging system) and UL 2251 (coupling interface). test.
Tang Jiade emphasized: "Combining UL's international experience and expertise in safety science, as well as the cooperation network with SAE and global verification resources, coupled with the domestic advanced and abundant SAE J1772 interface standard laboratory energy, can not only meet Taiwan's domestic demand The market can provide a more complete product testing platform for Taiwan's export products of electric charging components, strengthen the certification of product safety and functional integration, and stabilize the international competitiveness of Taiwan's industry.
