What Is the Liquid-Cooled EV Charger Modules Market?

Liquid-cooled EV charger modules are power-conversion components used inside high-performance DC EV charging systems. Their primary function is to convert incoming AC electricity into controlled DC electricity that can be supplied to an EV battery. Unlike conventional air-cooled modules, liquid-cooled systems circulate a coolant through thermal pathways around heat-generating power components.

This approach becomes increasingly valuable as charger output rises. Higher power means greater heat generation within semiconductors, inductors, capacitors and other electrical components. Liquid cooling allows manufacturers to maintain operating temperatures while keeping the module compact and supporting higher power density.

Current commercial products demonstrate the evolution of this technology. For example, UUGreenPower offers liquid-cooled charging modules with high protection levels, high power density, low noise and wide-voltage capabilities. Its UR100040-LQ-DD module is designed around liquid-cooling heat dissipation and provides constant-power output across a wide voltage range.

Tonhe has also developed 40 kW liquid-cooled charging modules using SiC power devices. One of its liquid-cooled modules provides a 50–1,000 VDC output range, peak efficiency of at least 97%, IP65 protection and a stated service life exceeding 10 years.

The market therefore sits at the intersection of power electronics, thermal management, EV charging infrastructure and high-voltage vehicle platforms.

Why Is Liquid Cooling Important for EV Charging?
