The core component of electric vehicles is the power battery pack. The quality of the power battery pack directly affects the performance of the vehicle. Lithium iron batteries have many advantages, such as energy density, no memory effect, low self-discharge rate, and long life spans. Therefore, lithium iron batteries have become an ideal power source for electric vehicles. 1 However, the thermal safety problems of lithium iron battery cannot be ignored. If the heat generated by the battery cannot be dissipated in time, it will cause the battery temperature to rise, or even thermal runaway. When the temperature rises up to 50°C, the electrochemical performance and cycle life of lithium iron battery will be seriously decreased. 2 Therefore, ensuring a power density and high energy density simultaneously has become increasingly challenging. 3 Some scholars have used the finite element method to model the multiphysics of lithium iron battery. However,

“…A liquid cooling system is the most common cooling strategy used in electrified vehicles [18]. Because of high thermal conductivity and heat transfer efficiency [19], it can control battery temperature development and distribution [20]. However, liquid cooling systems have complexity in structure, water leakage risk, and additional weight and energy consumption [21].…”

Jute is a cheap, eco-friendly, widely available material well-known for its cooling properties. In electric vehicles (EVs), dissipating a huge amount of the heat generated from lithium-ion batteries with an efficient, light, and low-power consumption battery thermal management system (BTMS) is required. In our previous study, jute fibers were proposed and investigated as a novel medium to enhance the cooling efficiency of air-based battery thermal management systems. In this paper, as the first attempt, jute was integrated with a phase change material (PCM) passive cooling system, and the thermal performance of a 50 Ah prismatic battery was studied. Temperature evolution, uniformity, and cooling efficiency were investigated. A comparison between the thermal behavior of the air-based BTMS and PCM-assisted cooling system was performed. The results indicated that adding jute to the BTMS increased the cooling efficiency and especially decreased the temperature development. Furthermore, the temperature difference (ΔT) efficiency was enhanced by 60% when integrating jute with PCM, and temperature uniformity improved by 3% when integrating jute with air-based BTMS. This article compared the integration of jute with active cooling and passive cooling; thus, it shed light on the importance of jute as a novel, eco-friendly, lightweight, cheap, available, and nontoxic material added to two strategies of BTMS. The setup was physically made and experimentally studied for the purpose of BTMS optimization.

“…However, despite its advantages, low heat transfer coefficient, uneven temperature distribution, and low efficiency are the main drawbacks of air-cooled BTMS [18,19]. To overcome the low heat transfer coefficient of air as the cooling medium, a hybrid system of BTMS was developed either by combining air-cooling with PCMs [20] or by integrating air-cooling with mini-channel liquid cooling [21]. These studies successfully lower the battery's temperature, but on the other hand, increase the BTMS power consumption.…”

Low-Cost Air-Cooling System Optimization on Battery Pack of Electric Vehicle

Temperature management for battery packs installed in electric vehicles is crucial to ensure that the battery works properly. For lithium-ion battery cells, the optimal operating temperature is in the range of 25 to 40 °C with a maximum temperature difference among battery cells of 5 °C. This work aimed to optimize lithium-ion battery packing design for electric vehicles to meet the optimal operating temperature using an air-cooling system by modifying the number of cooling fans and the inlet air temperature. A numerical model of 74 V and 2.31 kWh battery packing was simulated using the lattice Boltzmann method. The results showed that the temperature difference between the battery cells decreased with the increasing number of cooling fans; likewise, the mean temperature inside the battery pack decreased with the decreasing inlet air temperature. The optimization showed that the configuration of three cooling fans with 25 °C inlet air temperature gave the best performance with low power required. Even though the maximum temperature difference was still 15 °C, the configuration kept all battery cells inside the optimum temperature range. This finding is helpful to develop a standardized battery packing module and for engineers in designing low-cost battery packing for electric vehicles.
