On November 15, the Ministry of Transport (MOT) solicited opinions on the mandatory national standard " Motor Vehicle Coolant- Part 2: Electric Vehicle Coolant (draft for comments)", with the deadline for feedback set for January 14, 2024.

This standard specifies the product classification, technical requirements, test methods, inspection rules, as well as requirements for labeling, packaging, transportation, and storage of coolants for electric vehicles. It is applicable to the production, inspection, and use of coolants prepared with ethylene glycol as the antifreeze agent and used in the thermal management systems of pure electric vehicle power batteries.

This standard is one of the three standards in the GB 29743 series. The other two parts are specifically for coolant for internal combustion engine vehicles (published in 2022) and coolant for fuel cell vehicles.

Currently, this standard has become an important technical support for market surveillance. The State Administration for Market Regulation (SAMR) has included engine coolant in the "National Key Industrial Product Quality and Safety Supervision Catalog (2021 Edition)", and will carry out inspection in accordance with the "Interim Measures for the Management of Product Quality Supervision and Sampling" and this standard. The Ministry of Transport (MOT) has also included engine coolant in the "Key Supervision and Management Product Catalog of the Transportation Industry (2013 Edition)", and will implement inspection in accordance with the "Administrative Measures for Product Quality Supervision and Sampling in the Road Transportation and Maritime Industries" and this standard. Overseas manufacturers should track this standard and analyze its potential impact on the sale of their products in the Chinese market in the future.
