Learn MoreBattery grouping can be achieved via clustering techniques based on characteristics like static capacity, internal resistance etc. The dynamic characteristics-based method considers the battery performance during the entire charging-discharging process and has become one of the most promising grouping method.
Essentially, battery grouping aims to categorize battery cells according to their diversities in various characteristics. These characteristics mainly comprise static capacity, voltage, internal resistance (Li, 2014) and thermal behavior (Fang et al., 2013). Battery grouping can be achieved via a similarity analysis of any characteristic above.
A two-stage distributed battery grouping scheme that splits the original centralized clustering approach into local clustering and global merging is proposed for consistency and efficiency improvement. These two stages are implemented on edge computing devices and cloud data center respectively.
To improve the consistence, battery grouping is employed, assembling batteries with similar electrochemical characteristics to make up modules and packs. Therefore, grouping process boils down to unsupervised clustering problem. Current used grouping approaches include two aspects, static characteristics based and dynamic based.
Mixed Grouping: Series-parallel batteries combine both series and parallel connections to achieve desired voltage and current. Internal Resistance: Internal resistance in a battery reduces the terminal voltage when the battery is supplying current. A battery is defined as an electrical element where chemical reactions produce electrical potential.
In constructing a battery by Series Grouping of cells, The cells are connected in series to form a battery. The positive terminal of each cell is connected to the negative terminal of another cell except for the two end cells. The two end terminals of the construct act as the positive and negative terminals of the battery as shown below:
