Design, Development and Thermal Analysis of Reusable Li-Ion Battery Module for Future Mobile and Stationary Applications

Abstract

The performance, energy storage capacity, safety, and lifetime of lithium-ion battery cells of different chemistries are very sensitive to operating and environmental temperatures. The cells generate heat by current passing through their internal resistances, and chemical reactions can generate additional, sometimes uncontrollable, heat if the temperature within the cells reaches the trigger temperature. Therefore, a high-performance battery cooling system that maintains cells as close to the ideal temperature as possible is needed to enable the highest possible discharge current rates while still providing a sufficient safety margin. This paper presents a novel design, preliminary development, and results for an inexpensive reusable, liquid-cooled, modular, hexagonal battery module that may be suitable for some mobile and stationary applications that have high charge and or discharge rate requirements. The battery temperature rise was measured experimentally for a six parallel 18650 cylindrical cell demonstrator module over complete discharge cycles at discharge rates of 1C, 2C and 3C. The measured temperature rises at the hottest point in the cells, at the anode terminal, were found to be 6, 17 and 22 °C, respectively. The thermal resistance of the system was estimated to be below 0.2 K/W at a coolant flow rate of 0.001 Kg/s. The proposed liquid cooled module appeared to be an effective solution for maintaining cylindrical Li-ion cells close to their optimum working temperature.

Multi-Objective Energy Management of a Micro-Grid Considering Stochastic Nature of Load and Renewable Energy Resources

“…Each time segment, the objective function given in (1) should be calculated and weighted according to the combined probability model (30). In this work, each time segment was represented by one hour.…”

“…The authors in [29] proposed a threelayered approach for optimizing the distributed optimal resource in multi-agent systems framework. Several efforts have been presented for developing a multi-types of energy storage systems where the authors in [30] proposed a novel design for an inexpensive reusable, liquid-cooled, hexagonal battery module to be suitable for mobile and stationary applications. An investigation and a comparison have been performed between of two types electrolytes including traditional salt-in-water and water-in-salt electrolytes for symmetric supercapacitors [31].…”

“…On the other hand, improved thermal characteristics should affect the results in the opposite way. Here, the thermal parameters are: thermal resistance 0.4 • C/W; thermal time constant 21,600 s (6 h); [67,73] and converter losses remain at 5%. For example, [73] shows that with a properly designed cooling system, the thermal resistance will almost be lower than 0.4 • C/W, or even be reduced to 0.2 • C/W.…”

A Review of Composite Phase Change Materials Based on Porous Silica Nanomaterials for Latent Heat Storage Applications

“…Higher energy availability has led to increasing living standards and economic development, but it also negatively impacting the environment. Efficient energy generation, storage and use are therefore becoming increasingly important, since they play a large role in both energy and industrial applications [ 1 , 2 ]. Storing thermal energy in the form of heat or cold is an important segment of the energy infrastructure.…”
