The study includes liquid-cooled high-power DC charging systems ranging from 150 kW to above 1 MW, covering key voltage architectures (400V, 800V, and 1000V+) and current ratings from 200A to 800A+ that influence charging performance and thermal management. It evaluates major connector standards including CCS, NACS, MCS, GB/T, and ChaoJi, along with factors such as thermal load, system efficiency, and liquid cooling adoption. The scope also covers public charging, fleet depot, and heavy-duty charging applications, end-user deployment ecosystems, and infrastructure-driven demand modeling.
