Cycle Life

Lithium-ion batteries (LIBs) are rapidly taking over the electric vehicle (EV) industry as the main energy storage system. They provide high energy efficiency, long cycle life, and low self-discharge compared to other battery chemistries. LIB is generally made up of a lithium metal oxide or phosphate cathode, a graphite anode, a polymer separator and a liquid electrolyte solution. The electrolyte is comprised of a lithium salt dissolved in a mixture of carbonates, such as ethylene carbonate (EC), dimethyl carbonate (DMC), ethyl methyl carbonate (EMC), etc. The melting point of ethylene carbonate (EC, 36.4°C) is higher than that of its analogue propylene carbonate (PC, –48 °C). Therefore, PC is an attractive candidate to improve the low temperature charge/discharge capacity and the fast charge capability of LIBs. Several groups have attempted to replace EC by PC. However, co-intercalation of PC-solvated Li+ ions results in serious exfoliation of graphite layers and a faster degradation of battery cycle life. We used a combination of additives in PC based liquid electrolyte containing LiPF6 salt, to address this issue. The developed electrolyte offers superior cycle life for the NMC/graphite pouch cell. The rationale for improved performance was analyzed with the help of characterization techniques such as ultra-high precision coulometry (UHPC), EIS, XPS and gas analysis

This paper presents a novel design for a test platform to determine the state of health (SOH) of lithium-ion batteries (LIBs). The SOH is a key parameter of a battery energy storage system and its estimation remains a challenging issue. The batteries that have been tested are 18,650 Li-ion cells as they are the most commonly used batteries on the market. The test platform design is detailed from the building of the charging and discharging circuitry to the software. Data acquired from the testing circuitry are stored and displayed in LabVIEW to obtain the charging and discharging curves. The resulting graphs are compared to the outcome predicted by the battery datasheets, to verify that the platform delivers coherent values. The SOH of the battery is then calculated using a Coulomb counting method in LabVIEW. The batteries will be discharged through various types of resistive circuits, and the differences in the resulting curves will be discussed. A single battery cell will also be tested over 30 cycles and the decrease in the SOH will be clearly identified.

Load Prediction

Over the last century, the energy storage industry has continued to evolve and adapt to changing energy requirements. To run an efficient energy storage system two points must be considered. Firstly, precise load forecasting to determine energy consumption pattern. Secondly, is the correct estimation of state of charge (SOC). In this project there is a model introduced to predict the load consumption based on ANN implemented by MATLAB. The Designed intelligent system introduced for load prediction according to the hypothetical training data related to two years daily based load consumption of a residential area. For another obstacle which is accurate estimation of SOC, two separate models are provided based on ANN and ANFIS for Lithium-ion batteries as an energy storage system. There are several researches in this regard but in this project the author makes an effort to introduce the most efficient based on the MSE of each performance and as a result the method by ANN is found more accurate.

With battery energy storage technology development, the centralized battery energy storage system (CBESS) has a broad prospect in developing electricity. In the meantime, the retired lithium-ion batteries from electric vehicles (EV) offer a new option for battery energy storage systems (BESS). This paper studies the centralized reused battery energy storage system (CRBESS) in South Australia by replacing the new lithium-ion batteries with lithium-ion second-life batteries (SLB) and evaluating the economic benefits with economic indicators as net present value (NPV), discounted payback period (DPBP), Internal rate of return (IRR) to depict a comprehensive understanding of the development potential of the CRBESS with the lithium-ion SLB as the energy storage system. This paper proposes a calculation method of frequency control ancillary services (FCAS) revenue referring to market share rate (MSR) when building the economic model. Moreover, the residual value of lithium-ion batteries is considered. This paper uses the economic model to calculate the profitability and development potential of CRBESS. From an economic perspective, the superiority and feasibility of CRBESS compared with CBESS were analyzed.
