To ensure efficiency, safety, and avoid potential failures for Li-ion batteries, reliable battery management during its full-lifespan is of significant importance. This chapter first introduces the background and motivation of Li-ion battery, followed by the description of Li-ion battery fundamentals and the demands of battery management.
Accurate life prediction using early cycles (e.g., first several cycles) is crucial to rational design, optimal production, efficient management, and safe usage of advanced batteries in energy storage applications such as portable electronics, electric vehicles, and smart grids.
It''s a bit like portable power packs that you can charge your mobile phone with when you''re out and about – only a solar battery is much much bigger (and less portable). You charge it up using your solar panels, and then use it to power your home, instead of using power from the grid. A solar panel battery costs around £5,000. Solar batteries vary in price, depending on the type
At present, the demand for a long lifetime of battery packs in the field of energy storage is becoming more and more prominent. However, the lifetime test of battery packs takes up much time and much expense.

Lithium-ion batteries are vital for powering many modern technologies. To ensure their effective use and optimal performance, it is essential to understand their lifespan, which can be divided into three key categories: cycle life, calendar life, and battery shelf life.These parameters influence the battery''s reliability, efficiency, and application suitability.
Traditional battery energy storage systems (BESS) are based on the series/parallel connections of big amounts of cells. However, as the cell to cell imbalances tend to rise over time, the cycle life of the battery-pack is shorter than the life of individual cells. New design proposals focused on modular systems could help to overcome this problem,
To optimal utilization of a battery over its lifetime requires characterization of its performance degradation under different storage and cycling conditions. Aging tests were conducted on commercial graphite/nickel-manganese-cobalt (NMC) Li-ion cells.
According to these results, the reliability of modular battery-packs is up to 20.24 % over the conventional BESSs for energy applications. With regards to power applications, the modular configurations'' reliability is up to 16.21 % higher than the MTTF corresponding to the conventional BESS.
Battery operating data from real-life scenarios are riddled with randomness, complexity, and multi-cell grouping, posing significant challenges for applying lifetime prognostic approaches developed from laboratory scenarios.

With active thermal management, 10 years lifetime is possible provided the battery is cycled within a restricted 54% operating range. Together with battery capital cost and electricity cost, the life model can be used to optimize the overall life-cycle benefit of integrating battery energy storage on the grid.
Fluctuations in electricity generation due to the stochastic nature of solar and wind power, together with the need for higher efficiency in the electrical system, make the use of energy storage systems increasingly necessary. To address this challenge, battery energy storage systems (BESS) are considered to be one of the main technologies .
Ultimately, rigorous studies on battery lifespan coupled with the adoption of holistic strategies will markedly advance the reliability and stability of battery technologies, forming a robust groundwork for the progression of the energy storage sector in the future. 3. Necessity and data source of early-stage prediction of battery life 3.1.
Two methods to extend lifetime include (1) oversizing the battery and thereby restricting its maximum daily DOD and (2) adding battery thermal management. These tradeoffs are shown in Figure 9. Daily average SOC is maintained at 45% across all cases. The SOC operating range is narrowed at the maximum and minimum extremes to sweep DOD.
To address this challenge, battery energy storage systems (BESS) are considered to be one of the main technologies . Every traditional BESS is based on three main components: the power converter, the battery management system (BMS) and the assembly of cells required to create the battery-pack .
If a thermal management system were added to maintain battery cell temperatures within a 20-30oC operating range year-round, the battery life is extended from 4.9 years to 7.0 years cycling the battery at 74% DOD. Life is improved to 10 years using the same thermal management and further restricting DOD to 54%.
