液冷が商用EVバッテリー熱管理の業界標準になりつつある理由
As electric commercial vehicles transition from early adoption to mainstream deployment, the limitations of traditional air-cooling systems have become impossible to ignore. In 2025, a comprehensive review published in MDPI’s journal Batteries systematically evaluated advanced cooling strategies — including indirect liquid cooling, phase change material (PCM) cooling, and hybrid approaches — and concluded that liquid cooling systems deliver the highest heat transfer efficiency for preventing thermal runaway in lithium-ion battery packs. The Physics Behind Liquid Cooling Superiority Liquid cooling works on a simple but powerful principle: liquids have significantly higher heat capacity and thermal conductivity than air. Water-glycol mixtures used in BTMS (Battery Thermal Management Systems) can absorb and transport […]
