Dober EV Coolant gains GB Standard approval in China
Woodridge, IL — With a lot of hard work and a dedication to innovation, Dober is excited to announce its EV-LC Coolant has passed rigorous GB standard testing in China.
The GB (or Guo Biao, "National Standard") standards are issued by the Standardization Administration of China. The standard published in draft form in 2024 for electric vehicle coolants, GB29743.2, outlines "product classifications, technical requirements and test methods, inspection rules, marking, packaging, transportation and storage for electric vehicle coolant," the Institute for Global Automotive Regulatory Research explains. Passing this important test is a necessary step before being able to sell into the Chinese market.
"At Dober, we take pride in our drive to innovate and adapt to a fast-changing regulatory environment when it comes to new-energy coolants," Dober CEO Chris Dobrez said. "This approval marks another significant step forward for Dober's next-generation coolant portfolio. We are excited to be one of the first companies to achieve this rigorous approval in China. This approval is the culmination of the hard work of our talented team, which strives every day to bring the best next-generation coolants to the world."
The Chinese government advanced the new electric vehicle coolant standard in response to safety concerns stemming from battery electric vehicle fires. The new GB standard for electric vehicles coolants calls for electrical conductivity levels below 100 microsiemens (µS) per centimeter.
Testing on the coolant was conducted in late 2024 through early 2025 by RIOH Automobile Testing Technology Co., Ltd. Dober's EV-LC coolant was assessed on a wide range of critical characteristics, including electrical conductivity, corrosion and stability, among many others.
Dober's next-generation coolant portfolio includes finished low-electrical conductivity coolants for both battery electric and fuel cell vehicles.
