BASF launches low-conductivity coolants to enhance EV battery safety and performance

BASF has introduced a range of low electrical conductivity coolants (LECCs) under the GLYSANTIN ELECTRIFIED line, developed specifically for electric vehicle battery systems to comply with China’s new GB 29743.2-2025 standard, which becomes effective on October 1, 2025. The new coolants are produced at BASF’s Pudong manufacturing facility in Shanghai and are designed to enhance battery safety and stability by reducing fluid decomposition and hydrogen generation.

The GLYSANTIN ELECTRIFIED LECCs are engineered to maintain low and stable electric currents even under exposure to high-voltage EV battery components, aiming to prevent overheating, fire, and explosion by minimizing decomposition and hydrogen formation. BASF says the formulation also provides corrosion protection and long-term material compatibility, validated by external certifications from SGS and RATTC, a subsidiary of the Ministry of Transport of China.

Initial production and market focus for these LECCs are centered in China, which BASF identifies as the largest market for new energy vehicles. According to BASF, the coolants are intended to support the evolving safety requirements in China’s electric vehicle industry. The company notes that future expansion plans depend on customer demand in other regions.
