As Electric Vehicle (EV) adoption accelerates, demand for faster charging continues to rise, making high-power charging stations a critical infrastructure component. However, the surge in power also brings increased heat generation, and traditional air-cooling methods are no longer sufficient to ensure the stability and safety required for prolonged high current operation. Liquid cooling technology has thus emerged as the core solution for nextgeneration thermal management in EV charging stations.
In April 2025, SINBON Electronics achieved a major milestone with its self developed liquid cooling system for EV chargers officially receiving the world’s first UL safety certification for liquid cooling systems. UL certification is globally recognized for its rigorous standards, which include comprehensive reviews of product design, material selection, structural safety, performance, and durability testing. Earning this certification affirms that SINBON’s liquid cooling system meets international benchmarks for safety, reliability, and manufacturing consistency — delivering a stable and robust cooling solution for high-power charging scenarios.
According to sources from SINBON, as ultra-fast charging technologies become mainstream, liquid cooling will play a critical role in enhancing the efficiency and
safety of charging equipment. The achievement of UL certification not only marks a major milestone in the company’s technological development but also lays a solid foundation for the global expansion of its products.
