“…Power batteries, as one of the most important parts in electric vehicles (EVs) and hybrid electric vehicles (HEVs) [3], have attracted the majority of attention from researchers and engineers. A whole battery pack in a vehicle commonly contains several single cells connected serially or in parallel [4]. A large quantity of battery cells will generate a large amount of heat and cause temperatures to rise during the charge and discharge process [5,6].…”

Featured Application: Authors are encouraged to provide a concise description of the specific application or a potential application of the work. This section is not mandatory.Abstract: High power cylindrical Ni-MH battery cells have a heavy heat load because of their high discharge rate and large equivalent internal resistance. This heavy heat load, together with an imbalanced flow in parallel liquid cooling systems, can lead to variances in the temperature of each cell in the entire battery pack, thereby reducing the life cycle of the battery pack. In this paper, a parallel-series combined liquid cooling system for a 288V Ni-MH battery pack was designed, and several parameters that influence the flow balance of the system by heat transfer and fluid dynamics were calculated. Then, a thermal-fluid simulation was executed with different parameters using StarCCM+ software, and the simulation results were validated by a battery pack temperature experiment on a bench and in a vehicle. The results indicate that the cell's temperature and temperature differences can be kept within an ideal range. We also determined that within the battery power requirements and structural spacing limits, the total flow rate of the cooling liquid, the cross-sectional area ratio of the main pipe to the branch pipes, and the number of internal supporting walls in each branch pipe need to be large enough to minimize the cell's maximum temperature and temperature differences.reduces the life cycle of a battery pack. At temperatures exceeding 50 • C, charging efficiency and battery life deteriorate the most rapidly due to heat [10,11]. Therefore, it is necessary to pay more attention to the research of battery thermal management system (BTMS), which is very important for battery performance, life and safety. Pesaran et al. [12] noted that Ni-MH and Li-ion batteries' ideal operating temperatures range from 25 to 40 • C, and the temperature differences between the cells within a battery pack should be below 5 • C. Literature ReviewPlenty of works have been done in the field of battery thermal management system for commercially sold EVs and HEVs in the market, such as direct air cooling, liquid cooling, phase change material, heat pipes, hybrid cooling system and other emerging cooling technologies.The air-cooling system uses air as the heat exchange medium to let the air sweep across the battery surface to take away the heat generated by the battery. The air-cooling system is the most widely used cooling mode with simple structure, light weight, low cost and convenient maintenance. Chen YF et al. [13] showed that the thermal conductivity of Li-ion battery was low, and air cooling alone could not meet the requirements of thermal management. Harmel et al. [14] and Chen et al. [15] analyzed the thermal balance of li-ion batteries and found that when the wind speed reached a certain degree, increasing the wind speed had little effect on the heat dissipation effect of the batteries. Nelson et al. [16] have shown that the cooling effect of an air-co...

“…Moreover, this battery selection process is costly and time-consuming The first step of battery selection is the identification of an appropriate technology for each specific application. To do this, different battery technologies must be analyzed and compared [6,7]. Once the battery selection is finalized, it is then necessary to obtain an accurate model.…”

With growing global commitment to renewable energy generation, the role of energy storage systems has become a central issue in traction power applications, such as electric vehicles, trains, and elevators. To achieve the optimal integration of batteries in such applications, without unnecessary oversizing, improvements in the process of battery selection are needed. Specifically, it is necessary to develop models able to predict battery performance for each particular application. In this paper, a methodology for the parametrization of a battery equivalent circuit model (ECM) based on capacity and pulse tests is presented. The model can be extrapolated to different battery technologies, and was validated by comparing simulations and experimental tests with lead-acid and lithium-ion batteries.

“…The major component for converting a conventional fuel vehicle to a pollution-free EV and the grid integration is its battery. With the proper selection, integration and performance management of a battery, the feasibility of EV can be improved [141][142][143][144][145][146][147][148][149][150][151][152][153][154]. According to different requirements, we chose different batteries.…”

The quest for energy conservation is a thought-provoking conundrum to researchers. Time to time they contributed towards this pursuit. In the 19th century, it was a fascinating idea about electric vehicles (EVs). As most of the developing countries depend on conventional energy sources, integration of EVs with renewable energy sources justified the cause. The parking slots became transformed into unlimited sources of clean energy. For the comfort of charging and better energy management, wireless power transfer technology was introduced to the charging station. As a fulfilment of the technology, the vehicle-to-grid (V2G) integration was implemented. It helped the bi-directional power flow between the vehicle and the grid with renewable energy. This study presents an extensive review of the renewable energy powered wireless charging and V2G integration of EVs. Various topologies are discussed with mathematical explanations and block diagrams. Concepts are validated with PSIM simulations.
