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.
Battery 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.
Voltage: Voltage is the measure of electrical force. High-voltage batteries have higher voltage than standard batteries, which means they can provide more power to devices. The voltage is determined by the battery’s type and number of cells. Battery Cells: A high-voltage battery consists of multiple cells connected in series.
The service life, safety, and capacity of lithium-ion power battery packs relies heavily on the consistency among battery cells. Grouping is an effective procedure to improve consistency by screening cells with similar performance and assembling them into an identical group.
Voltage-based grouping method divides cells into different groups according to their OCVs or load voltages. Although measuring the voltage is simple and direct, the grouping results are usually unsatisfactory because the voltage variation during the charging-discharging process is neglected.
Types of high voltage batteries Lithium-ion batteries are widely used due to their high energy density and lightweight design. They are commonly found in smartphones, laptops, and electric vehicles. These batteries can store a lot of energy in a compact size, which makes them ideal for portable electronics.
