In this article, a battery pack cooling system having multiple lithium-ion (LIB) cells with laminar nanofluid (NFD) flow and phase change materials (PCMs) was simulated using the finite element method (FEM). The system's walls were curved, NFD two-phase method. PCMs positioned inside elliptical enclosure encompassed all cells. temperature of cells, heat transfer coefficient (HTC), by transiently investigated alteration vertical distance between batteries from 0.7 to 1.1, horizontal 0.5 1, input size 1.5. data optimized artificial intelligence (AI) technique achieve best results. results showed that maximum pressure drop occurs at biggest input, highest distance, lowest (583% difference). Similarly, (MXT) (TLIB) occurred distances smallest dimensions (7.15° HTC (794.26 W/m2K) dimensions.

Abstract Lithium-ion batteries are used in many applications and their performance can be seriously affected by the operation temperature. In this paper, a numerical approach is employed to evaluate thermal of three different cell configurations battery module. Sixteen cylindrical 18650 LIBs were discharged under 1C, 2C, 3C 4C-rate at 1 m/s 2 airflow. Numerical simulations implemented using ANSYS Fluent software. Findings evidence that there exists behaviour module associated with arrangement location inlet outlet airflow on LIB case. The maximum temperature was 64.88 °C, reached 4C for cells arranged rhombus pattern air speed, minimum 28.10 °C 1C triangular cooling m/s. influences process

In this paper, the thermal management of a battery module with novel liquid-cooled shell structure is investigated under high charge/discharge rates and runaway conditions. The consists 4 × 5 cylindrical batteries embedded in aluminum multiple flow channels. suppression propagation were experimentally examined. temperature rise discharging process significantly greater than that charging phase. As coolant speed increases, maximum decreases slightly, while difference remains at same level, expense much-increased pressure drop. With presented shell, was for both internal corner runaway. It found adjacent can be maintained 70 °C, indicating successfully suppressed by heat dissipation through surrounding liquid flow. addition, electrically induced profile along interconnection identified imaging. Hot spots on confluence busbars series connection. order to improve safety modules, parallel connection recommended, which reduce busbar 4.86 as determined numerical simulations. Experimental measurements also conducted verify simulation results.

Lithium-ion batteries are usually connected in series and parallel to form a pack for meeting the voltage capacity requirements of energy storage systems. However, different configurations battery module collector positions result equivalent resistances, leading current inhomogeneity, which seriously reduces lifetime safety pack. Therefore, order quantitatively analyze influence resistance on distribution, this study researched initial cell distribution by developing mathematical models configurations. Then, explored multiple inhomogeneity under dynamic condition. The results show that discharge with modules can be improved keeping each same distance its collector. Furthermore, homogeneity edge is affected position single innovatively proposes symmetrical collectors pack, greatly improve modules, thereby improving

The existing photovoltaic power generation multi-source collaborative control technology cannot improve the effect of microgrid, resulting in high peak load balancing cost microgrid. Therefore, based on differential evolution (DE)-gray wolf optimization (GWO) algorithm is adopted. main components microgrid system, such as equipment, hydroelectric and battery pack, are modeled. With goal minimum maximum transmission power, water, light energy storage carried out. gray Wolf used to solve multi-objective problem water optimized by DE algorithm. Experiments show that convergence speed DEVOLU-Gray obviously accelerated, falling into local optimal solution completely avoided. After application this method, photovoltaic, hydraulic, run order, ensure smooth operation economic benefit
