Driving the Future: Electric Cooling Pumps in New Energy Vehicles

As the world accelerates toward electrification, thermal management has become one of the most critical areas defining the performance, safety, and efficiency of new energy vehicles (NEVs). At the heart of this system lies the electric cooling pump—a compact but powerful technology driving next-generation innovation.

1. Why Cooling Pumps Matter in EVs

EVs and plug-in hybrids generate significant heat from battery packs, inverters, and fast-charging systems. Without efficient cooling, thermal stress can shorten component lifespan and compromise safety. Electric cooling pumps enable:

• Precise temperature control via smart electronics (PWM, CAN, LIN communication).
• High energy efficiency by running only when needed, unlike mechanical pumps.
• Compact, lightweight integration with battery and motor cooling circuits.

2. Mechanical vs Electric Cooling Pump: A Technology Leap

Electric cooling pumps outperform mechanical pumps across key performance dimensions:
