In the thermal management segment of commercial and industrial energy storage systems, energy storage circulation pumps play a core role in circulation and fluid replenishment. Their performance directly determines the system's stability and energy efficiency. Shenpeng Technology has dedicated years to the application field of brushless DC motors, innovatively applying this technology to energy storage circulation pumps and fluid replenishment pumps, and developing solutions that combine high efficiency and reliability.

Hall Sensor Closed-Loop Control: Enhancing Operational Precision and Stability

Energy storage circulation pumps need to precisely adjust their speed to match dynamic heat dissipation requirements. Traditional open-loop control is prone to flow fluctuations, which impairs thermal management efficiency. By leveraging Hall sensor closed-loop control technology, Shenpeng Technology has built a high-response control system for its P9008 circulation pump and P6092 fluid replenishment pump.

The Hall sensor captures real-time signals of the motor rotor's position and speed, feeding them back to the controller to form a dynamic adjustment loop. For the high-flow scenarios of the P9008 circulation pump, this technology controls speed fluctuations within an extremely narrow range, ensuring stable coolant circulation flow. Meanwhile, the P6092 fluid replenishment pump achieves precise control of fluid replenishment volume through this technology, preventing liquid level imbalance in the energy storage system. In commercial and industrial energy storage systems, when the heat generation of battery modules and PCS components changes abruptly, both pumps can adjust their speed in an extremely short time to accurately match heat dissipation needs—eliminating energy waste while preventing local overheating.

IP68 Waterproof Rating Achievement: Adapting to Complex and Harsh Operating Environments

Commercial and industrial energy storage systems often operate in complex environments with humidity, dust, and other harsh conditions. Thus, the IP68 waterproof rating has become a critical indicator of pump reliability. Shenpeng Technology has adopted differentiated material solutions for the P9008 and P6092 to achieve high protection performance.

The P9008 circulation pump uses "die-cast aluminum + special anti-corrosion coating" for its main frame. Its surface undergoes multi-layer passivation treatment to form a dense protective film, showing no rust in salt spray tests. Components in contact with water flow are made of PPS black engineering plastic, which can withstand harsh environments ranging from -40℃ to 125℃.

The P6092 fluid replenishment pump takes PPA material as the core of its frame. This material combines excellent mechanical strength and chemical resistance, maintaining dimensional stability in environments from -20℃ to 70℃. Through the synergy of structural design and material properties, both products boast high waterproof performance, meeting the strict protection requirements of energy storage cabins.

Long-Life Test Data: Ensuring Long-Term Reliable Operation

Commercial and industrial energy storage systems require long-term continuous operation. Shenpeng Technology has conducted long-life working condition tests on the P9008 and P6092 to verify their long-term reliability.

The test environment simulates the typical working conditions of energy storage systems:

The P9008 operates continuously at full speed, with 50% ethylene glycol aqueous solution as the medium.

The P6092 performs fluid replenishment cycles at a frequency of once every 10 minutes, with a pressure fluctuation range of 0.1-0.3 MPa.

After 20,000 hours:

The P9008 shows minimal flow attenuation, and the bearing temperature rise remains within a reasonable range.

The response accuracy of the P6092 remains above 95% of its initial value, with no significant changes in key electrical parameters.

This achievement is attributed to the optimized design of materials and structure: The die-cast aluminum frame of the P9008 optimizes the heat dissipation path, reducing the motor's operating temperature; the PPA frame of the P6092 reduces operational vibration and significantly lowers the friction coefficient. Test data confirms that both pumps can meet the long-term service life requirements of energy storage systems, greatly reducing operation and maintenance costs.
