For the battery cooling loop, driven by the pump, the coolant flows into the battery pack to absorb heat generated by the battery pack. Then the heat exchange process between the coolant and refrigerant will occur while the coolant flows into the Chiller.
ICLC separates the coolant from the battery through thermal transfer structures such as tubes, cooling channels, and plates. The heat is delivered to the coolant through the thermal transfer structures between the battery and the coolant, and the heat flowing in the coolant will be discharged to an external condensing system [22, 33]. 3.1.
Efficient cooling is crucial, and electric coolant pumps provide a solution by circulating coolant fluid through the cooling system, facilitating heat dissipation. Electric coolant pumps are driven by electric motors, allowing precise electronic control and optimization of coolant flow rate based on cooling demands.
At the end of fast cooling, the battery temperature is about 28 °C. In this stage, the average coolant inlet temperature is 10 °C lower than the battery temperature, and the average coolant outlet temperature is 2.25 °C lower than the battery temperature.
Electric coolant pumps typically operate within a voltage range of 12V or 24V for automotive applications. What is the range of flow rates for electric coolant pumps? The flow rate of electric coolant pumps can vary from a few liters per minute to over 100 liters per minute, depending on the application and cooling requirements.
By preventing excessive heat buildup, this cooling system significantly reduces the risk of battery fires and the release of toxic gases, thereby enhancing the safety of both the vehicle and its occupants. Another aspect of user safety is battery cell containment.

Batteries work based on the principle of a voltage differential. At high temperatures, the electrons inside become excited, which decreases the difference in voltage between the two sides of the battery. Because batteries are only manufactured to work between certain temperature extremes, they will stop working if there is no cooling system to keep it in a working range. Cooling …
