Abstract

Charge algorithms for Li-Ion batteries require that charging current stop once a maximum voltage threshold is reached. Each battery in a Li-Ion pack must be individually monitored for this condition, so charging of the entire pack ceases as soon as one cell reaches this voltage limitation. Cell balancing algorithms seek to remove charge from the offending cell to equalize voltage and enable additional charging of the pack. This paper considers the technical merits of this approach and the issues associated with its implementation.

Life Prediction of Large Lithium-Ion Battery Packs with Active and Passive Balancing

Conference Shi, Ying; Smith, Kandler; Zane, Regan; ...

Lithium-ion battery packs take a major part of large-scale stationary energy storage systems. One challenge in reducing battery pack cost is to reduce pack size without compromising pack service performance and lifespan. Prognostic life model can be a powerful tool to handle the state of health (SOH) estimate and enable active life balancing strategy to reduce cell imbalance and extend pack life. This work proposed a life model using both empirical and physical-based approaches. The life model described the compounding effect of different degradations on the entire cell with an empirical model. Then its lower-level submodels considered the complex physicalmore »« less

Modular Approach for Continuous Cell-Level Balancing to Improve Performance of Large Battery Packs: Preprint

Conference Muneed ur Rehman, M.; Evzelman, M.; Hathaway, K.; ...

Energy storage systems require battery cell balancing circuits to avoid divergence of cell state of charge (SOC). A modular approach based on distributed continuous cell-level control is presented that extends the balancing function to higher level pack performance objectives such as improving power capability and increasing pack lifetime. This is achieved by adding DC-DC converters in parallel with cells and using state estimation and control to autonomously bias individual cell SOC and SOC range, forcing healthier cells to be cycled deeper than weaker cells. The result is a pack with improved degradation characteristics and extended lifetime. The modular architecture andmore »« less

Advanced Cell-Level Control for Extending Electric Vehicle Battery Pack Lifetime

Conference Rehman, M.; Zhang, Fan; Evzelman, Michael; ...

A cell-level control approach for electric vehicle battery packs is presented that enhances traditional battery balancing goals to not only provide cell balancing but also achieve significant pack lifetime extension. These goals are achieved by applying a new life-prognostic based control algorithm that biases individual cells differently based on their state of charge, capacity and internal resistance. The proposed life control approach reduces growth in capacity mismatch typically seen in large battery packs over life while optimizing usable energy of the pack. The result is a longer lifetime of the overall pack and a more homogeneous distribution of cell capacitiesmore »« less

Investigation of Active Life Balancing to Recondition Li-ion Battery Packs for 2nd Life

Conference Rasheed, Marium; Kamel, Mohamed; Wang, Hongjie; ...

An investigation is presented into the application of active life balancing battery management systems to recondition inhomogeneous Li-ion battery packs and achieve homogeneity in capacity for second life. This paper proposes a life balancing objective map, which controls the state of charge references for each cell in a battery pack based on its capacity relative to other cells. The impacts of life balancing objective maps on the reconditioning time and overall pack capacity fade are considered. Moreover, the proposed approach accounts for various load and environmental effects, including depth-of-discharge, battery pack temperature, number of cycles per day, and cells’ restingmore »« less

Synthesis and characterization of LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} (R{bar 3}m) for lithium-ion (shuttlecock) batteries

Journal Article Ohzuku, Tsutomu; Ueda, Atsushi; Kouguchi, Masaru - Journal of the Electrochemical Society

The synthesis and characterization of LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} were carried out in order to improve the electrochemical properties of LiNiO{sub 2} for lithium ion batteries. Single phase of LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} (R{bar 3}m; a = 2.86 {angstrom} and c = 14.24 {angstrom} in hexagonal setting) was obtained by heating a reaction mixture of LiNO{sub 3}, NiCO{sub 3}, and Al(OH){sub 3} at 750 C under an oxygen stream for 20 h and examined in nonaqueous lithium cells. LiAl{sub 1/4}Ni{sub 3/4}O{sub 2} was oxidized to {open_square}{sub 3/4}Li{sub 1/4}Ni{sub 3/4}O{sub 2} in the voltage range of 3.5--4.8 V. {open_square} denotes themore »« less
