“…These advantages have prompted on studies on hybrid solarwind energy systems with ESSs [4][5][6][7][8]. Several studies have focused on the optimum sizing of hybrid systems with advanced optimization techniques considering resource variability and load uncertainty [9][10][11][12][13][14][15][16][17].…”

h i g h l i g h t sThermal swelling shape is different than Li-ion intercalation swelling shape. Nonuniform temperature and gap creation leads to a convex shape at free conditions. Important parameters of thermal mechanics are estimated through experiments. A coupled thermal-structural analysis accurately predicts thermal swelling shape. Nonuniform temperature still plays a critical role at pack conditions. Keywords:Lithium-ion battery Battery swelling shape Thermal expansion The coefficient of thermal expansion The coupled thermal-structural analysis a b s t r a c tThe thermal mechanics of Lithium-ion (Li-ion) batteries is explored with a focus on thermal swelling. Experiments show for the first time that the swelling shape of prismatic battery cells due to temperature variations is significantly different from that due to Li-ion intercalation in unconstrained conditions. In contrast to uniform and orthotropic Li-ion intercalation swelling in a direction perpendicular to electrodes, the nonuniform temperature distribution in the jellyroll and the gaps/voids between electrodes result in distinguishable different swelling shapes. A unique coupled thermal-structural analysis with a simple, but efficient 3-D finite numerical model is proposed to investigate the impact of temperature variations on the thermal behaviors of battery cells. Anisotropic heat conduction and temperature dependency of the coefficient of thermal expansion are taken into account and found to have an impact on temperature distribution and thermal expansion. Experimental validation of the proposed model clearly demonstrates that the coupled thermal-structural analysis with the proposed model can predict accurately the thermal swelling at unconstrained conditions. The solution at pack (constrained) conditions shows that the nonuniform temperature distribution of the jellyroll still plays a critical role for the thermal swelling shape, although the gaps/voids do not occur because of the constraints from spacers in the pack, suggesting that the estimation of core temperature is important. Such an accurate model, able to estimate cell thermal behavior, is beneficial to the design of Li-ion batteries, development of stress or strain sensors, optimum sensor placement, and thermal management of not only single battery cells but also battery packs.

“…Thus, one of the conventional solutions that can be considered in order to suppress this unsteady output power is to integrate PV panels with paralelly-connected rechargeable batteries. Generally, a lithium-ion secondary battery is commonly used due to its characteristics of high energy density, good power output, high coulombic efficiencies, good cycle life with a broad cycle range and comparatively low heat output [7][8].…”

An extensive implementation using alternative energy resources such as photovoltaic and wind energy is extremely necessary to encounter an incoming energy crisis in the near future. Nonetheless, it is crucial to realize an efficient solution scheme that is able to interact with the entire system automatically so that the daily consumed power can be managed wisely, specifically in family-unit power system or also known as a Home Energy Management System (HEMS). In this paper, the numerical model that computes an optimized capacity of energy consumption based on weekly forecast has been performed in order to provide the stable energy that is insulated from the instability of weather change. An economic HEMS that is able to increase the energy consumption in normal days while maintaning minimum stable energy in bad weather conditions is proposed. The simulated system had succeeded to supply energy at least 10 Ah to the load for night consumption in most cases during the rainy days from the year 1982 to 2010 which consisted of one-third proportion from a small-capacity-sized battery pack (30 Ah).
