2025 Headlines & Industry Developments

Huawei showcased a 720 kW liquid-cooled charging system capable of delivering 500 A continuously, targeting commercial highway corridors. The company also launched megawatt-class liquid-cooled charging stations for freight and heavy-duty vehicles, with peak ratings reaching 1.44 MW and 2,400 A.

bp pulse is deploying 400 kW liquid-cooled charging stations across the United States, supporting both CCS and NACS connectors. These systems use liquid cooling to enable higher power delivery without oversized cables.

Electrify America has expanded its U.S. network by 30% in 2025, adding next-generation 350 kW chargers with liquid-cooled cables to sustain 500 A operation while improving durability and user experience.

The European market for ultra-fast charging doubled its share of ≥350 kW chargers in 2024 compared with 2023, driven by operators such as Fastned and Iberdrola. This shift places liquid-cooled modules and cables at the center of Europe's charging ecosystem.

Manufacturers have introduced wide-voltage, silicon carbide-based modules, enabling higher efficiency, reduced thermal losses, and compact cabinet design. Several vendors now offer 40-60 kW modules, reducing the number of units per cabinet and simplifying system integration.

Market Trends

Rising Site Power: From 400 kW to 1 MW

400 kW systems are now standard in new deployments across North America and Europe, while 720 kW cabinets are entering commercial rollout. Heavy-vehicle megawatt charging is being introduced, with power levels of 1.0-1.44 MW. These power levels require liquid cooling at both the module and connector levels.

Higher Current, Smaller Footprint

Liquid-cooled cables sustain 500 A continuous and up to 650 A peak. This reduces cable diameter and improves ergonomics at charging stations. To support these demands, AC/DC modules integrate advanced thermal management and higher switching efficiency.

Silicon Carbide Adoption

SiC MOSFET-based modules are now being integrated by major manufacturers, delivering efficiency above 97%, higher switching frequencies, and reduced cooling loads. The shift to SiC accelerates the adoption of compact 40-60 kW liquid-cooled modules.

Wide Voltage Compatibility

Modules supporting 150-1000 Vdc enable compatibility with both 400 V and 800 V EV architectures. This reduces complexity for operators, as a single cabinet can serve different vehicle platforms, including future high-voltage trucks.

Larger Module Sizes Reduce Integration Costs

The transition from 30 kW to 40-60 kW module sizes allows operators to deploy fewer modules per cabinet. This reduces backplane complexity, wiring losses, and maintenance costs, while increasing system reliability.

Reliability and Total Cost of Ownership

Liquid-cooled modules deliver lower noise, reduced dust intrusion, and longer service lifetimes. Many manufacturers now claim more than 10 years of reliable service under continuous high-load operation, a key factor for highway corridor charging networks.

Connector Transition: CCS to NACS

In North America, NACS is being widely adopted alongside CCS. High-current NACS implementations require liquid-cooled solutions to sustain performance without overheating, ensuring interoperability across networks.

Policy and Supply Chain Impact

U.S. tariff changes in 2025 have created uncertainty in module sourcing and cost structures. In response, manufacturers are localizing production and diversifying their supply chains, particularly for silicon carbide components. Despite these challenges, demand remains strong due to accelerating EV adoption and government-backed infrastructure programs.

Editorial Summary

The AC/DC liquid-cooling charging module industry is entering a decisive growth phase. As networks expand toward 400-720 kW systems and prepare for megawatt-class charging, liquid cooling has shifted from an optional feature to a core enabler of high-power charging. Silicon carbide adoption, higher voltage ranges, and modular scaling are redefining the technology landscape. Despite tariff-related risks in 2025, manufacturers and charging operators are investing aggressively to meet surging demand.

This combination of rapidly rising power requirements, technological innovation, and infrastructure expansion positions the global market to more than double in size by 2031.
