18-32V Electric Coolant Pump For Lithium Ion Batteries Cooling In Energy Storage Systems

The OWP-BL43-200 Electric Coolant Pump is engineered to deliver reliable, high-performance thermal management for Lithium-ion Battery Energy Storage Systems (BESS). Built with automotive-grade components and advanced protective features, this pump ensures stable operation in extreme environments while optimizing energy efficiency—making it the ideal choice for energy storage cooling applications.

• Precision Flow Control: Equipped with constant flow regulation technology, the pump maintains consistent liquid circulation to support uniform battery cooling, preventing overheating and extending battery lifespan.

• Comprehensive Protection Mechanisms: Features reverse polarity protection, dry running protection, over-voltage/over-current safeguards, and overload/over-temperature protection—minimizing downtime and ensuring long-term reliability.

• Efficient & Durable Design: Adopts a single-stage centrifugal structure with magnetic force transmission (shield pump design) and a high-efficiency brushless DC motor. Professional electromagnetic theory verification boosts motor efficiency by 3-5% compared to competitors, while the brushless design reduces power consumption and delivers a service life exceeding 20,000 hours.

• Optimized Hydraulic Performance: Hydraulic components (impeller and volute) undergo professional software simulation calculations to achieve optimal matching, enhancing hydraulic efficiency for superior heat dissipation.

• Extreme Environment Adaptability: Constructed with automotive-grade electronic components, the pump operates seamlessly in working temperatures ranging from -40℃ to +85℃ (-40°F to +185°F) and humidity up to 90%, with an IP68 protection rating for dust and water resistance.

Lithium-ion batteries in energy storage systems generate significant heat during charging/discharging cycles, which can degrade performance and pose safety risks without effective thermal management. The OWP-BL43-200 addresses this critical need by providing efficient, consistent coolant circulation:

• Removes excess heat from battery modules to maintain optimal operating temperatures, preserving capacity and cycle life.

• Adapts to dynamic load changes in BESS with stable flow control, ensuring reliable cooling during peak demand.

• Withstands the harsh operating conditions of energy storage installations (indoor/outdoor, temperature fluctuations) thanks to IP68 protection and wide temperature tolerance.

• Reduces energy consumption via high-efficiency motor design, aligning with the sustainability goals of modern energy storage projects.

Whether for utility-scale BESS, commercial energy storage systems, or industrial battery banks, the OWP-BL43-200 Electric Coolant Pump delivers the performance, durability, and protection required for critical thermal management applications.
