OPEN ACCESS
The transition to electric vehicles (EVs) within tropical regions necessitates a concentrated emphasis on the advancement of battery technology. However, the challenges of extreme environmental conditions demand a reliable thermal management system to prevent thermal degradation and ensure safety. Therefore, this study proposes a bionic mini-channel cold plate with a roots-based configuration. A numerical approach was applied using a localized heat generation model at a discharge rate of 5 C. The thermal management performance of the roots-based structure was evaluated and compared with the conventional straight-based structure at various Reynolds numbers (Re). The results indicated that the roots-based structure configuration with five channels demonstrated superior heat dissipation performance by expanding the effective contact area. It successfully suppressed the maximum temperature (Tmax) of the battery to 34.65 ℃ and maintained temperature uniformity with a temperature difference (ΔT) of 4.2 ℃. In contrast, the straight-based configuration was only able to suppress Tmax to 35.08 ℃ and ΔT to 4.56 ℃. However, the roots-based structure generated higher flow resistance, resulting in a pressure drop of up to 2000 Pa, which caused a decrease in the j/f ratio. Nevertheless, this configuration is justified as a necessary trade-off to ensure the thermal safety of the battery.

The transportation sector significantly contributes to global greenhouse gas emissions, with Indonesia accounting for 53% of the country's total emissions [1-4]. The transition to electric vehicles (EVs) is a strategic solution to achieve decarbonization targets [5-7]. In general, EVs are primarily powered by Lithium-ion (Li-ion) batteries due to their high energy density, long life cycle, and low self-discharge rate [8, 9]. However, the adoption rate of energy storage systems in Indonesia remains considerably low, primarily attributed to safety concerns associated with these technologies. Li-ion batteries exhibit a marked sensitivity to operating temperatures, resulting in a high potential for self-heating, which can trigger electrical abuse and thermal runaway [10]. As a tropical country, Indonesia's equatorial climate directly exacerbates this thermal vulnerability. Li-ion batteries operate optimally within a narrow temperature range of 25 ℃ to 40 ℃, with a tolerance for temperature variations not exceeding 3 ℃ to 5 ℃ [11-13].
Furthermore, most of the population and economic centers in Indonesia are located in coastal and lowland areas with tropical rainforest and tropical monsoon climates, where the average ambient temperature is recorded in the range of 30 ℃ to 33 ℃ [14]. Due to the high ambient temperatures, batteries in tropical climates experience much higher thermal stress and are highly susceptible to extreme heat accumulation during operation. Therefore, the development of a Battery Thermal Management System (BTMS) specifically designed to adapt to tropical environments is urgently needed to ensure safety and accelerate EV adoption in these regions.
BTMS can be classified into three different types of cooling mediums, including water-based, liquid-based, and phase change material-based (PCM-based) [15]. Among these three types, liquid-based cooling is the most widely developed method due to its superiority in reducing heat with a high capacity [16-18]. Liquid-based cooling is generally integrated with a cold plate to maximize the heat transfer process from the battery [19]. Therefore, the geometric structure of the channels formed on the cold plate plays a crucial role in ensuring the effectiveness of the thermal management. Monika et al. comprehensively studied the characteristics of a straight mini-channel cold plate by investigating various aspects, including channel width, number of channels, coolant type, flow rate, coolant temperature, ambient temperature, and discharge rate [20]. Regarding geometric factors, the selection of width and number of channels plays a critical role in influencing the resultant pressure drop. While the straight mini-channel cold plate effectively maintains battery temperatures between 25 ℃ and 40 ℃, it is important to consider the need for power consumption compensation.
To address the limitations of the straight channel cold plate, Zhang et al. [21] modified the geometry of the cold plate by implementing inclined channels. The best configuration was found with an inclination angle of 15 °, which was proven to increase thermal effectiveness by up to 79.64%. However, this study was limited because it did not consider the control of battery temperature uniformity. Conversely, Bao et al. [22] used a different approach by proposing a wide straight channel cold plate (WCP), which was directly compared with several complex cold plate structure designs, such as serpentine, bifurcated, and U-turned channels. Although the study revealed that complex channel designs could improve heat transfer performance in cold plates, the WCP was proven to produce the lowest pressure drop. However, the performance of the WCP requires a large volume of coolant, and its performance degrades as the channel width narrows.
The complexity of channel geometry in cold plates escalated considerably with the implementation of a bionic design approach. Zhan et al. [23] proposed a tree-like bionic structure cold plate with the aim of maintaining the optimal operating temperature range in batteries. In addition, Hu [24] applied a bionic sapling-shaped channel cold plate design to overcome the limitations of traditional complex channel cold plates. Both studies demonstrated effective and superior maximum temperature reduction with a uniform temperature distribution. Furthermore, the bionic channel design on the cold plate produces a lower pressure drop compared to traditional models.
Based on the literature review, it is evident that geometric factors are key parameters for ensuring the effectiveness of thermal management performance. Moreover, the bionic channel cold plate design has been proven to be a geometric approach with superior thermal management performance and lower power consumption. However, the development of bionic channel structures is limited due to their complexity, which makes it challenging to find optimal geometric parameters and triggers an increase in flow resistance in the channel. Therefore, this study proposes a simple bionic structure approach using a roots-based mini-channel structure. Additionally, this approach is designed to maintain the effectiveness of battery thermal management performance in tropical environmental conditions. Thus, this study provides a targeted contribution toward producing a reliable and adaptive BTMS.
3.1 Validation
Before analyzing the effectiveness of the proposed thermal management system, the accuracy of the numerical model was evaluated during the validation stage. This validation process was carried out by comparing the temperature curve from the numerical simulation results with the experimental data reported by Rao et al. In this comparison, the operational parameters were set to actual conditions, specifically at a discharge rate of 5 C under a constant ambient temperature of 25 ℃ [30]. Based on the comparison graph shown in Figure 5(a), the simulation results clearly showed a temperature increase trend that was similar to the experimental measurement results at five different measurement point locations. This trend, with a minimal deviation range, strongly indicated that the implemented five-segment heat generation model was valid and highly reliable in capturing the thermal dynamics of the battery. The mean absolute percentage error of the numerical simulation is shown in Figure 5(b).
Furthermore, the spatial characteristics of the thermal phenomena in the battery were visualized through the temperature distribution contours in Figure 5(c). The visualization clearly showed that the temperature profile inside the battery cell during operation at a high discharge rate (5 C) was non-uniform, leading to a spike in temperature differences that exceeded safe operational limits. The highest heat accumulation point was consistently found to be centered in the upper area of the battery, precisely in the area adjacent to the positive tab. This finding fundamentally confirmed that the high concentration of current flow around the terminal area triggered an increase in ohmic resistance, which ultimately produced extreme heat intensity in that localized region. This non-uniform thermal distribution characteristic also provided empirical justification that the placement of cooling strategies must be precisely designed to reduce heat buildup in critical areas of the battery.

3.2 Analysis
Figure 6 presents the performance of the thermal management system at a constant flow rate (Re = 200), which was comprehensively evaluated by comparing the evolution of the maximum temperature (Tmax) and the temperature difference (ΔT). In Figure 6(a), the thermal characteristics during the discharge period can be classified into three main phases. In the initial phase (0–100 s), the Tmax curve showed a sharp increasing gradient due to the dominance of heat generation immediately after the discharge cycle began. At the peak of this phase, the bionic roots-based structure with the largest number of channels successfully reduced the temperature spike to 38 ℃, outperforming the straight-based structure, which reached 39 ℃. However, an examination of the temperature uniformity in Figure 6(b) revealed that this initial spike instantly triggered an increase in ΔT beyond the safe tolerance limit (≤5 ℃). This phenomenon indicated that the fluid convection capacity at Re = 200 was not effective enough to dissipate the local heat concentration, thus creating an extreme spatial temperature gradient imbalance at the beginning of operation.

(b)
Figure 6. Battery thermal characteristics at Re = 200: (a) Maximum temperature (Tmax); (b) Temperature difference (ΔT)
Entering the middle phase (100–500 s), the heat dissipation rate from the coolant circulation gradually began to offset the battery's heat generation. The Tmax curve exhibited a downward trend, with the roots-based cold plate consistently demonstrating superior performance by maintaining the maximum temperature at a minimum of around 35.5 ℃. This temperature suppression significantly affected the thermal balance, as indicated by a decrease in ΔT approaching the safe limit in the 400 to 500 s interval. However, the cooling performance at Re = 200 degraded during the final phase of the discharge cycle. The high increase in Depth of Discharge (DOD) triggered a significant escalation of heat generation. As a result, the Tmax curve again increased beyond the critical threshold of 40 ℃ in all mini-channel cold plate structure configurations. This cooling system failure was exacerbated by a spike in the ΔT curve beyond the safe operational limit. Overall, the results of the investigation under these conditions confirmed that although the roots-based design offered better heat dissipation effectiveness, it was still inadequate to address battery temperature homogeneity.

Furthermore, the influence of Re variations on Tmax was further investigated, as shown in Figure 7(a). The analysis indicated that the changes in Tmax began to demonstrate a significant impact at Re = 400. Conversely, the effectiveness of the ΔT profile became clearly evident in the Roots-based configuration with 5 channels at Re = 800. Increasing the flow to Re = 1400 demonstrated that all structural variations of the mini-channel cold plate exhibited satisfactory ΔT performance. However, among the tested variations, the Roots-based with 5 channels design was identified as the superior structural configuration, demonstrating the capability to optimally reduce ΔT by up to 4.2 ℃.
To understand the underlying mechanism of thermal management enhancement and evaluate its hydraulic compensation, the thermohydraulic characteristics of the system were evaluated based on the parameters of the average convective heat transfer coefficient (hl) and pressure drop (ΔP), as illustrated sequentially in Figure 8. The results of the study indicated that the escalation of Re proportionally strengthened the convective heat transfer while increasing the internal flow resistance in all configurations. From the aspect of heat transfer effectiveness in Figure 8(a), an increasing number of channels implied a decrease in hl.

(b)
Figure 8. Performance of cooling system with different Re: (a) Heat transfer coefficient (h); (b) Pressure drop (ΔP)
At a constant Re, the addition of channels minimized the fluid momentum, thereby reducing the local flow velocity in each branch. However, the bionic roots-based mini-channel cold plate structure consistently validated its superiority by producing superior convective effectiveness compared to the straight-based channel. Branches with smaller hydraulic diameters characterized the root morphology, thus interrupting the growth of the thermal boundary layer. Through this mechanism, the roots-based configuration with 3 channels was proven successful in achieving the highest hl.
Nonetheless, the hydraulic analysis presented in Figure 8(b) indicated that, despite the superior heat transfer performance of roots-based mini-channel cold plates, they experienced a significantly greater pressure drop in comparison to conventional straight-based structures. The roots-based mini-channel morphology triggered greater internal flow resistance, causing hydraulic losses that resulted in increased pump power consumption, as quantified in Table 4. The roots-based mini-channel cold plate was identified as the configuration with the highest ΔP, reaching more than 2000 Pa, with a pump power consumption reaching 8.58 × 10-3 Watt. However, this loss can be suppressed by increasing the number of channels. Therefore, the straight-based design with 7 channels recorded the lowest ΔP of around 1400 Pa, with a pump power consumption of only 5.36 × 10-3 Watt.

In this study, a visualization of the temperature distribution contours of the battery cell at a maximum flow rate (Re = 1400) across all mini-channel cold plate structure configurations is presented in Figure 9. In general, the integration of a mini-channel cold plate triggered a significant thermal redistribution. The concentration of extreme heat accumulation in the terminal area (tabs) was successfully dissipated and distributed towards the bottom cross-section of the cell. However, the structure configuration with a minimum number of channels still showed heat localization, especially in the internal region of the battery cell. This phenomenon confirmed that batteries have very low thermal conductivity. Thus, the effective contact area of this configuration was not enough to maximize heat dissipation in the internal cell under these conditions.
Figure 9. Temperature distribution of battery at Re = 1400: (a) Straight based, 3 channels; (b) Straight based, 5 channels; (c) Straight based, 7 channels; (d) Roots based, 3 channels; (e) Roots based, 5 channels
In order to enhance thermal management in batteries, it was crucial to augment the number of channels. This expansion not only led to a significant reduction in the maximum temperature observed but also improved the thermal homogeneity across the battery. In addition to increasing the number of channels, reconstructing the mini-channel cold plate structure with a bionic approach was proven to produce superior thermal management performance. The roots-based configuration with 5 channels demonstrated the lowest temperature range with the most uniform distribution. Thus, the roots-based branching morphology facilitated the spread of flow distribution with a more significant effective contact area.
On the other hand, the pressure distribution contour inside the mini-channel cold plate at Re = 1400 is visualized in Figure 10. This visualization illustrates the trade-offs associated with the implementation of bionic structures in relation to the hydraulic load within the cooling system. In the roots-based structure configuration with a minimum number of channels, a dominant high-pressure zone was identified in the upstream area. This phenomenon occurred due to the branching morphology formed with a smaller hydraulic diameter, resulting in a high stagnation pressure zone. In this case, the internal flow resistance was very dominant, triggering significant energy losses. Internal flow resistance was proven to be minimized in the straight-based structure configuration. In addition, increasing the number of channels effectively minimized the intensity of the high-pressure zone on the upstream side. Thus, the straight-based configuration with 7 channels produced the lowest pressure drop.

In addition, the balance between the heat transfer effectiveness enhancement and hydraulic trade-off was holistically evaluated based on the non-dimensional j/f ratio in each mini-channel cold plate structure configuration, as represented in Figure 11. In general, all configurations showed a similar parabolic curve trend. The j/f ratio value escalated in the initial phase and reached a peak point around Re = 400. However, as the flow rate increased, the j/f ratio showed a decreasing trend. This phenomenon indicated that at higher flow rates, the growth of hydraulic resistance due to pressure drop increased more dominantly compared to the heat transfer effectiveness of the cooling system.
Figure 11. j/f ratio with different Re
Overall, the straight-based configuration recorded a higher j/f ratio compared to the roots-based one in each number of channels. The straight-based variant with 3 channels was identified as the configuration with the highest j/f ratio. Despite having a higher pressure drop compared to a larger number of channels, the configuration showed a more significant average heat transfer, thus maximizing the effectiveness of the mini-channel cold plate. In contrast, roots-based bionic structures tended to produce massive pressure drops, which degraded the overall j/f ratio. However, there was a trade-off between the cooling system's effectiveness and the performance indicators for battery thermal management. While the straight-based configuration with 3 channels appeared effective thermally, it did not meet the battery thermal management performance indicators for maintaining temperature homogeneity below safe thresholds. On the other hand, although the roots-based structure with 5 channels required higher hydraulic load compensation, this configuration could satisfy the battery thermal management performance indicators well at lower flow rates. Therefore, the decrease in the effectiveness of thermohydraulic performance in this roots-based structure provided strong justification as an essential trade-off to ensure the reliability and thermal safety of Li-ion batteries, especially for operational adaptation in extreme tropical climates.
This study proposed a mini-channel cold plate with a bionic roots-based structure as a Li-ion BTMS to prevent thermal degradation and ensure operational safety in tropical climates. Using a numerical approach, a localized heat generation model accurately captured the phenomenon of non-uniform temperature distribution, where heat accumulation was concentrated in the positive tab area due to the dominance of ohmic resistance during a 5 C discharge cycle. The investigation results demonstrated that the use of a roots-based mini-channel cold plate configuration significantly improved heat dissipation performance by expanding the effective contact area through a bionic branching morphology. The roots-based configuration with 5 channels demonstrated superior performance, successfully suppressing the maximum temperature (Tmax) to 34.65 ℃ and satisfying the safe limit of battery temperature homogeneity with a temperature difference (ΔT) of less than 5 ℃.
However, the enhanced effectiveness of convective heat transfer (hl) in this bionic design necessitated significant compensation for the hydraulic load. The complexity of the structural branching induced a stagnation pressure zone in the upstream area, which resulted in a massive pressure drop (ΔP) due to internal flow resistance. A comprehensive thermohydraulic equilibrium evaluation confirmed that the straight-based configuration with 3 channels exhibited the highest j/f ratio. However, this configuration proved ineffective in satisfying thermal management performance in terms of battery temperature homogeneity. On the other hand, the roots-based configuration with 5 channels provided strong justification as an essential trade-off for ensuring a reliable and uniform battery temperature distribution. Nevertheless, the primary limitation of the roots-based mini-channel cold plate approach remains its high pressure drop. Thus, further research is needed to optimize the geometric parameters of the roots-based structure in order to minimize hydraulic losses without sacrificing its superior thermal management effectiveness.
