High Quality Electronic Water Pump For Electric Vehicle

High Quality Electronic Water Pump for Electric Vehicle

 

 

The electronic water pump uses a brushless DC motor (BLDC) to drive the impeller to rotate, and the coolant is sucked in from the inlet through centrifugal force and discharged from the outlet after being pressurized. The motor is controlled by the control unit (ECU), receives temperature sensor signals (such as battery temperature, motor temperature), and adjusts the PWM duty cycle in real time to change the speed (usually in the range of 2000-8000 rpm) to achieve precise flow control (0.5-20 L/min).

Power battery thermal management

Cooling: Prevent thermal runaway caused by battery temperature > 45°C during fast charging, and the flow rate is dynamically adjusted according to the temperature difference of the single cell (±0.5°C accuracy).

Heating: Circulate warm air fluid in a low-temperature environment to quickly heat the battery to above 10°C and restore discharge capacity.

Drive motor and electronic control heat dissipation

Maintain the motor winding temperature < 150°C to prevent permanent magnet demagnetization; automatically increase the water pump speed when the IGBT module temperature > 100°C.

Cooperation with the heat pump air conditioning system

The motor waste heat is transported to the cabin through coolant in winter, reducing PTC heating energy consumption and increasing endurance by 10%.

Fuel cell system cooling

Provide constant temperature cooling (60–80°C) for hydrogen fuel cell stacks to ensure reaction efficiency.

 

 

 

 

 

Q1: How to choose the voltage of the electronic water pump?
A1: The application voltage of the whole vehicle is mostly 12v, and the commercial vehicle is mostly 24v.

 

Q2: What are the main functions of the electronic water pump?
A2: The main functions are three-electric cooling, motor cooling (motor cooling, generally single motor, some are dual motors), electronic control cooling, and battery cooling.

 

Q3: What is the function of the electronic water pump?
A3: The function of the electronic water pump is to transport the coolant.

 

Q4: What are the advantages of the electronic water pump?
A4: The electronic water pump changes the speed according to different temperatures and scenes to reduce energy consumption.

 

Q5: What issues should be paid attention to during the installation of the electronic water pump?
A5: The centrifugal pump does not have the function of self-priming. It must be installed below the water tank to allow water to flow in automatically.

 

Q6: What are the types and control methods of the electronic water pump?
A6: Brushless motor, the control method is vector control, and the communication method is PWM/LIN,
