US Liquid-Cooled EV Charging Cable Market Scope

US Liquid-Cooled EV Charging Cable Market Growth Drivers

Rising Demand for High-Power DC Fast Charging Drives Adoption of Liquid-Cooled EV Charging Cables

The rapid expansion of high-power DC fast-charging infrastructure is a key growth driver for the U.S. liquid-cooled EV charging cable market, as rising charger power increases the need for effective thermal management. In 2025, the U.S. continued expanding its DC fast-charging network, with the Department of Energy’s Alternative Fuels Data Center recording more than 36,000 DC fast-charging ports in the country at the end of 2025. At the same time, charging infrastructure is shifting toward higher-power systems. DOE identifies high-power charging (HPC) as reaching up to 400 kW for light-duty EVs and 1+ MW for medium- and heavy-duty vehicles, enabling faster charging and greater vehicle utilization.

Higher current levels generate greater heat within charging cables, making liquid cooling increasingly important for maintaining operating temperatures while supporting high-power delivery without excessive cable thickness or weight. This trend is reinforced by the growing deployment of 350-kW and higher chargers, particularly for highway corridors and commercial applications. Consequently, continued investment in DC fast-charging stations, combined with the transition toward 350-kW, 400-kW, and megawatt-class charging, is expected to accelerate adoption of liquid-cooled charging cables across U.S. public, fleet, and heavy-duty charging infrastructure.

Recent Trends

Increasing Development of NACS-Compatible Liquid-Cooled Charging Cables in the US

The increasing development of NACS-compatible liquid-cooled charging cables is emerging as an important product-development trend in the U.S. market. The transition toward the SAE J3400-based NACS interface is encouraging cable manufacturers to adapt high-power cable technologies to the connector standard increasingly used across North American EV charging. In February 2026, Phoenix Contact expanded its North American portfolio with NACS and CCS Type 1 charging cables, while announcing that liquid-cooled NACS cables supporting more than 600 A are expected by the end of 2026.

This development is significant because Phoenix Contact's existing liquid-cooled technology can support up to 1,000 A and 1 MW in high-power charging applications, demonstrating the technical pathway toward higher-current NACS systems. The company also states that NACS is gaining momentum across the U.S., with major automakers adopting the standard and charging networks transitioning toward it. Consequently, suppliers are increasingly developing liquid-cooled cable solutions specifically compatible with the evolving U.S. charging interface.

US Liquid-Cooled EV Charging Cable Market Opportunities and Challenges

Rising Thermal-Management Challenges at Ultra-High Charging Currents Create Opportunities for Advanced Liquid-Cooled Cables

The increasing power and current requirements of EV charging are creating a major thermal-management challenge for the U.S. liquid-cooled EV charging cable market. As charging power rises, cables must carry higher currents without excessive temperature increases, cable diameter, weight, or performance degradation. This challenge is becoming particularly important in heavy-duty and megawatt charging, where ABB’s MCS1200, introduced for e-truck charging, delivers 1.2 MW continuously at 1,500 A. Such current levels substantially increase the heat that must be dissipated from the cable and connector, making effective thermal management critical for reliable high-power charging.

This thermal challenge is creating a direct opportunity for manufacturers to develop higher-current liquid-cooled cables capable of supporting ultra-fast and megawatt charging. A recent example is ABB’s OM Duo, which offers an 800-A liquid-cooled cable and connector, compared with 600 A for its phase-cooled configuration and 375 A for its air-cooled NACS option. The liquid-cooled configuration supports 150–980 VDC, demonstrating how liquid cooling enables substantially higher current delivery while maintaining a compact charging system.

The opportunity is expanding further with ABB's OM X-Series, launched in May 2026, which uses an end-to-end liquid-cooled architecture including liquid-cooled charger cables, and scales from 800 kW to 10 MW and beyond across more than 100 charge points. This directly demonstrates the industry's movement toward liquid-cooled infrastructure for sustained, megawatt-scale charging.
