The optimal structural parameters control the T max and ΔT of the battery at 37.58°C and 3.67°C, respectively. Zeng et al. (2022) employed a curved micro heat pipe array (MHPA) as a bridge for heat transfer between the battery to the LCP and arranged aluminum heat-conducting elements between the MHPA and the battery to extend the contact area.
The constant temperature test chamber was set to 25°C, with the battery module connected to the battery test system and left in the chamber for 3 hours. Linked the LCP to the battery liquid cooling temperature control machine utilizing a hose. Set T in = 25°C and F c = 60 mL/min through the control panel.
The ΔT is 0.58°C, and the average ΔT of the cells is only 0.16°C. This indicates good temperature uniformity among the single batteries with HCLC heat dissipation. The maximum ΔT in the battery pack is mainly reflected in the individual batteries, which is caused by the small radial thermal conductivity of cylindrical batteries. Figure 11.
The change in battery pack thermal behaviour is consistent with the change in the coupling surface heat transfer rate. The thermal behaviour of the battery pack undergoes significant changes when the N is increased from 3 to 4. However, further increasing the N has a diminishing impact.
By monitoring the maximum temperature of the module and the ambient temperature, a method for controlling the flow rate and the inlet temperature of the cooling water has been developed to implement an intermittent liquid cooling strategy for the battery module.
Also, the fundamental operation of the battery cell changes with temperature. This means that temperature gradients in cells can have a significant effect on performance and lifetime. You can extend this to cells at different temperatures in the pack.
