Batteries are by far the most effective and frequently used technology to store electrical energy ranging from small size watch battery (primary battery) to
Jiang et al. [33] measured cell variations of a 95S5P 18.5 kWh LFP battery pack after aging and showed a maximum of 7% SOC variation reduced the maximum available capacity of the pack by 25%. Paul et al. [24] studied initial nominal capacity and resistance variations.
In addition to battery pack capacity, researchers in Ref. [28] used battery pack internal resistance as the battery pack SOH indicator. These two battery pack SOH indicators reflect the aging levels of battery cells in the battery pack, but fail to evaluate the effect of consistency deterioration on the battery pack performance.
In the battery pack capacity test, the battery pack is also charged at 0.1C from battery pack SOC = 0 to battery pack SOC = 100%. The cutoff condition of the charge process is that the voltage of any battery cell reaches to 3.65 V.

By definition, a Battery Energy Storage Systems (BESS) is a type of energy storage solution, a collection of large batteries within a container, that can store and discharge electrical energy upon request. The system serves as a buffer between the intermittent nature of renewable energy sources (that only provide energy when it''s sunny or
The Climate Institute''s recent analysis with Navius Research shows that battery storage capacity needs to rise above 12,000 megawatts by the end of this decade and to around 50,000 megawatts by mid-century to align with Canada''s climate targets. Energy Storage Canada similarly estimates that the net zero transition will require
Despite this, most of the attention is paid to power batteries with small energy/power densities, and the non-uniform characteristics of large-capacity energy storage batteries are rarely studied. Recently, Zhang et al. [23] established a 1D-3D ETC model to study the temperature behaviors of a 280 Ah energy storage battery cell.
However, Sweden is more prominent in the field of residential energy storage and has ambitious plans to deploy grid-scale battery energy storage systems. In 2024 alone, Sweden announced that it will operate approximately 400MW of energy storage systems, a number that far exceeds that of other Nordic countries.
A battery module is a housing unit for battery cells. On the other hand, a battery pack is a series of battery cells connected as a series or parallel. Battery packs are largely used in electric vehicles, smartphones, laptops, and for renewable energy sources. Both battery packs and modules play different roles concerning energy storage.
