Customer ServiceSince the batteries in the battery pack will generate a lot of heat during operation, the performance of the battery pack will be severely affected. As a result, new energy vehicles are increasingly being developed with a focus on enhancing the rapid and uniform heat dissipation of the battery pack during charging and discharging.
Battery heat builds up quickly, dissipates slowly, and rises swiftly in the early stages of discharge, when the temperature is close to that of the surrounding air. Once the battery has been depleted for some time, the heat generation and dissipation capabilities are about equal, and the battery’s temperature rise becomes gradual.
As the rate of charge or discharge increases, the battery generates more heat energy. The battery's efficiency and longevity are negatively impacted by excessive heat. In cylindrical Li-ion batteries, the highest heat generation typically occurs at the center of the axis and then radiates outward to the cylinder's surface.
The integration of advanced heat dissipation technologies, such as heat pipe cooling plates, remote heat transfer heat pipes, and liquid-cooled cold plates, presents a promising solution for efficiently managing the thermal challenges posed by high-power battery modules.
Fluctuations in the battery’s transient operating conditions change the HGR instantly, but much time elapses before the desired heat dissipation effect is achieved through a practical BTMS control strategy. This inherent delay significantly increases the risk of battery TR.
This indicates that after the maximum surface of the flat heat pipe is fully contacted with the battery monomer, the heat dissipation of the battery monomer in the liquid cooling plate with a width smaller than its own reaches a state of uniform downward heat transfer.
