An electronic water pump is an electrically driven device that transfers liquids (such as coolant) from one location to another. It operates by an electric motor driving the impeller to rotate, imparting energy to the liquid through the impeller's action. This generates centrifugal or axial forces, thereby achieving liquid conveyance. This pump is a brushless motor-driven centrifugal shielded pump, featuring communication capability and variable speed control; The motor stator and rotor are shielded by a waterproof sleeve, the impeller is directly mounted on the pump shaft, and the controller is integrated into the product. This design offers high operational reliability, high transmission efficiency, a compact overall structure, and minimal space requirements.
This electronic water pump is specifically engineered for energy storage thermal management systems, operating directly from mains power (220VAC 50Hz) without requiring additional power equipment.
Suitable applications include:
- Battery thermal management systems for centralised energy storage power stations and distributed storage projects (e.g., commercial/industrial storage, residential storage)
- Other energy storage sector applications
The product structure comprises five primary components:
• Motor section: Features a brushless motor comprising stator and rotor, offering high efficiency, extended lifespan, and low noise operation
• Fluid section: Centrifugal pump design incorporating impeller, volute casing (with inlet/outlet ports), and flow-through components
• Controller section: Communicates with the unit's ECU, receives PWM control signals, and provides feedback on pump operational status; incorporates fault diagnosis and protection functions
• Electrical interfaces: One 220VAC power supply interface and one PWM communication interface
• Other components: Pump housing, mounting brackets, and other structural elements
