Custom EV Charging Station Liquid Cooling Pump for EV Manufacturer, Factory

An EV Charging Station Liquid Cooling Pump for EV is a thermal management component that circulates low-conductivity coolant through DC fast charger power modules, preventing semiconductor thermal throttling during high-load operation. As a specialized Small Water Pump engineered for high-voltage EVSE environments, it maintains continuous operation at ambient temperatures from -40°C to 70°C.

Product Description

On Demand Recirculation Pump Installation Guidelines

According to the IEA Global EV Outlook 2025, global EV sales exceeded 17 million units in 2024, driving fast charging capacity to grow tenfold by 2030. The liquid-cooled charging station market is projected to reach $18.4 billion by 2035 at a 17% CAGR.

The brushless motor architecture of a Dc Pump Small eliminates mechanical brush wear, enabling continuous duty cycles. It circulates a 50/50 ethylene glycol-water mixture through microchannels in silicon carbide inverters.
