This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: If battery packs for electric vehicles (EVs) and hybrid electric vehicles (HEVs) are to operate effectively in all climates, thermal management of the packs is essential. In this paper, we will review a systematic approach for designing and evaluating battery pack thermal management systems. A thermal management system using air as the heat transfer medium is less complicated than a system usingliquid cooling/heating. Generally, for parallel HEVs, an air thermal management system is adequate, whereas for EVs and series HEVs, liquid-based systems may be required for optimum thermal performance. Further information on battery thermal management can be found on the Web site www.ctts.nrel.gov/BTM.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal management system is necessary to control the operating temperature of the lithium ion batteries in battery packs for electrical and hybrid electrical vehicles. This thesis studies, develops and models novel battery thermal management systems for the battery packs in hybrid electric vehicles and electric vehicles. The systems' thermal performances are assessed through thermal and electrochemical models. The performances of the proposed systems are investigated in terms of various performance measures including the maximum temperature in the pack and the temperature distribution throughout the battery pack and through each battery. The results show that pool based systems achieve better performance for cylindrical battery packs than for prismatic battery packs. For a pool system, covering 30% of the battery height reduces the maximum battery temperature by 28% to 40% depending on the fuel type for a high intensity cycle. To achieve 28% to 40% reduction in the prismatic battery maximum temperature from the case where there is no cooling, the pool system has to cover 80% of the battery height. The best performing system for prismatic battery packs is the tube based system, where the aluminum cold plate has tubes completely filled with coolant to maintain the battery temperature within range needed for the best performance possible by the system. The tube cold plate based system maintains 80% less coolant in the battery pack at a time than the direct contact pool based system while achieving a higher performance in terms of the maximum battery temperature and the maximum temperature difference across the battery pack. The response time for the proposed systems reached nearly 10 times faster than liquid and air systems proposed in the literature. Compared with the literature the pool based system response was 1.7% of the cycle time compared to around 17% for the cycle time for the mini channel cold plate cooling system.

This book was released on 2014 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Battery pack needs to generate a high output within a very short time to meet the power demand of an electric vehicle when it is in acceleration. High discharge current causes significant warming of the Li-ion cells due to internal resistance within the cells. LiFePO4 batteries, however, can be used efficiently only within an operating temperature in the range of 20oC to 40oC. The life span and lifecycle of the battery will reduced significantly if the temperature goes above the recommended range. The rationale of this study is to develop an innovative evaporative cooling battery thermal management system (EC-BThMS) to control the battery temperature in the range of 20oC to 40oC. The simplified mathematical equations have been developed in this study for the kinematics analysis and simulation to investigate the temperature profile of the battery based on discharge current drawn, total heat generation and total heat dissipation from the battery. The performance investigation of the EC-BThMS has been conducted both theoretically and experimentally during discharging mode. Theoretically, it was found that the battery temperature varies from 26.5oCto 31oCfor discharge current in the range of 40 A to 100 A. Experimentally, testing results in IIUM campus road found that the battery temperature varies from 28oC to 34oC for discharge current in the range of 35 A to 120 A. While testing results in Sepang International Circuit (SIC) showed that the battery temperature was in the range of 26oC to 35oCfor discharge current in the range of 60 A to 80 A. The performance of developed EC-BThMS in SIC has also been compared with two types of air cooling battery thermal management systems (AC-BThMS) used in others Proton Saga EV. It was found that the Proton Saga EV with EC-BThMS can save 17.69% more energy than with AC-BThM 1 and 23% than with AC-BThMS 2. The correlations between the measured and predicted values of temperature profiles of the battery during operation have been found to be 97.3%. This is indicates that the predicted data over the measured data have a closed agreement and thus, substantially verified the mathematical model.

This book was released on 2011 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal management of traction battery systems for electrical-drive vehicles directly affects vehicle dynamic performance, long-term durability and cost of the battery systems. The time-efficient yet accurate computational model for the battery thermal management system is essential to improve the performance, safety, and life time of the battery systems. In this analysis, the thermal management system is divided into two different perspectives: pack level and cell-level thermal management system. For the pack level modeling, a new battery thermal management method using a reciprocating air flow for cylindrical Li-ion (LiMn 2 O4 /C) cells was numerically analyzed using (i) a two-dimensional Computational Fluid Dynamics (CFD) model and (ii) a lumped-capacitance thermal model for battery cells and a flow network model. The results of the CFD model were validated with the experimental results of in-line tube-bank systems which approximates the battery cell arrangement considered for this study. The numerical results showed that the reciprocating flow can reduce the cell temperature difference of the battery system by about 4°C (72 % reduction) and the maximum cell temperature by 1.5°C for a reciprocation period of 120 seconds as compared with the uni-directional flow case. Such temperature improvement attributes to the heat redistribution and disturbance of the boundary layers on the formed on the cells due to the periodic flow reversal. From the cell level concern, the spatial-resolution, lumped-capacitance thermal models for cylindrical battery cells under high Biot number (Bi>1) conditions where the classical lumped-capacitance thermal model is inapplicable because of the significant temperature variation in the battery cells was presented in this analysis. The improved lumped-capacitance thermal models were formulated using first- and second-order Hermite integral approximations. For a validation of the results from the lumped-capacitance models, one-dimensional, transient analytical (exact) solutions using the Green function were obtained for the cylindrical Li-ion battery cells. It was found from the comparison of the results from the computational models that the spatial-resolution, lumped-capacitance thermal models accurately predict the temperatures (core, skin and area-averaged) of the battery cell under various battery duty cycles for a wide range of the Biot numbers covering air cooling to liquid cooling conditions. The battery heat generation was approximated by uniform volumetric joule and reversible (entropic) losses.

This book was released on 2016 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the regulations on internal combustion engine vehicles, there is a large demand of hybrid and electric vehicles with large battery packs as Energy Storage Systems (ESS) capable of long ranges and decreased emissions. These battery packs output large heat loads during charge-depletion mode and currently require activity cooling to keep the batteries within operating conditions. The current systems relied on to achieve this are the air and liquid cooled thermal management systems. A recent alternative approach to current cooling for ESS thermal management is the use of phase-change materials (PCMs). PCMs regulate the temperature of the ESS by leveraging the latent heat of fusion to absorb large amounts of energy at constant temperature while changing phase from solid to liquid. While PCMs have large heat capacities, the downside is their low thermal conductivity which cases them to melt unevenly, which is a main reason PCM is not ideal for cooling systems. The study will involve fully investigating the use PCM into a hybrid-electric vehicle battery thermal management system. The proposed methodology is to mix thermal conductivity enhancing material, loose carbon fibers, into the PCM to spread the heat absorbed more evenly throughout the entire mass. This material matrix characterized in order to determine the necessary material and thermal properties to justify its use and implantation in the EcoEagles 2016 Chevrolet Camaro for vehicle testing and validations. Results obtained during multiple vehicle tests have demonstrated that the PCM has successfully kept the battery pack at a safe operating condition of under 45°C. This was done passively resulting in a reduced overall vehicle energy consumption and increased vehicle battery pack efficiency. The study continues by investigating the use of a shape-stabilized phase-change material cold plate that is capable of addressing several issues that are present with the bulk PCM plate in its current state on the vehicle.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Battery Thermal Management Systems are necessary for the overall efficiency and life cycle of vehicle as well safety of passengers and vehicle, as elevated operating temperatures have adverse effect on the efficiency, life cycle and safety of the Li-ion battery packs. The operating temperature prescribed by many studies for improved performance and better life cycle of Li-ion batteries is around 25° C. In some worst case scenarios, high operating temperature may lead to thermal runaway in the battery, causing immense amount of heat generation, even leading to an explosion. To avoid all these dangerous events, battery thermal management is utilized to regulate the temperature of the battery pack. In this thesis, a novel battery thermal management system based on liquid cooling principle is proposed. The system involves dual purpose cooling plate for prismatic Li-ion batteries, which can maintain the temperature under normal conditions as well as mitigate the heat generated during thermal runaway. An experiment was performed on the prismatic Li-ion battery to measure the heat generation trends. The battery was discharged at 5C to replicate aggressive conditions. The data for maximum heat flux generated in the Li-ion battery was obtained. An estimated amount of heat generated during thermal runaway was calculated. A conjugate heat transfer method was used to simulate the cooling plates for normal operation and thermal runaway. The plates were simulated with two flow rates for normal operation and three flow rates for thermal runaway. Three different designs of cooling plates were compared on the basis of surface temperature, pressure drop and flow rate. The final design was selected based on the comparison with the rest of the cooling plates. The selected cooling plate can: Maintain the temperature of battery below 25°C during normal operation. Dissipate the maximum possible heat generated during thermal runaway and bring the temperature to less than 80°C. Maintain least possible pressure drop in both conditions. A stress and modal analysis was performed on the final cooling plate to analyze the structural integrity of the design. The selected cooling plate porotype was manufactured.

Book excerpt: This research presents a method for efficiently and reproducibly comparing diverse battery thermal management concepts in an early stage of development to assist in battery system design. The basis of this method is a hardware-based thermal simulation model of a prismatic Lithium-Ion battery, called the Smart Battery Cell (SBC). By eliminating the active chemistry, enhanced reproducibility of the experimental boundary conditions and increased efficiency of the experimental trials are realized. Additionally, safety risks associated with Lithium-Ion cells are eliminated, making the use of the SBC possible with thermal management systems in an early state of developed and without costly safety infrastructure. The integration of thermocouples leaves the thermal contact surface undisturbed, allowing the SBC to be integrated into diverse thermal management systems.
