The OWP-BL43-200 Electric Coolant Pump is specifically designed to support Battery Management Systems (BMS) in electric trucks, hybrid trucks, electric passenger cars, and hybrid passenger cars. In these applications, the pump plays a vital role in maintaining battery temperature within the optimal operating range, which directly impacts battery performance, charging efficiency, and overall lifespan.
For electric and hybrid trucks—often subjected to heavy loads, long operating hours, and extreme temperature fluctuations—the pump’s robust construction and wide temperature tolerance (-40℃ to +85℃) ensure reliable thermal management even in the harshest conditions. Its constant flow control prevents overheating during high-power discharge or rapid charging, safeguarding the battery pack and extending its service life.
In electric and hybrid passenger cars, the pump’s low noise level (≤60dB) and energy-efficient design align with consumer demands for quiet, eco-friendly vehicles. The IP68 rating and automotive-grade components make it resistant to moisture, dust, and vibration, ensuring consistent performance in daily driving scenarios—from city commutes to long-distance trips.
By efficiently circulating coolant through the BMS, the OWP-BL43-200 helps optimize battery performance, reduce energy loss, and enhance the safety and reliability of electric and hybrid vehicles, making it an indispensable component for modern automotive manufacturers.
