How does a battery cooling system improve temperature uniformity?
The proposed cooling improves the temperature uniformity of the battery up to 57% and reduces the temperature rise of the battery to 14.8% with a rise in coolant flow rate from 652 mL/min to 1086 mL/min .
Why is air used for cooling of battery modules arranged in series?
When air is used for cooling of battery modules arranged in series, the middle and rear portion of batteries are at high temperature to the low heat capacity of air. The temperature of the battery pack near the outlet is very high and the temperature distribution is highly non-uniform.
How does direct liquid cooling affect battery performance?
In direct liquid cooling, the inlet temperature of the coolant has a significant impact on the electric performance of the battery. Cooling efficiency improves when the coolant inlet temperature is reduced in direct liquid cooling.
How does a coolant pump work?
The coolant tube inlet is stacked on top of the coolant tube outlet or vice versa. Then, a coolant circulation pump is used to circulate the coolant inside the coolant tube around the battery pack in a closed-loop for heat absorption. The coolant travels to the end and “u-turn” back (downward or upward) to the starting point.
How does ICLC separate coolant from Battery?
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.
How does a car battery accumulator work?
