Abstract Batteries are often packed together to meet voltage and capability needs.
However, due to variations in raw materials, different ages of equipment, and manual
operation, there is inconsistency between batteries, which leads to reduced available
capacity, variability of resistance, and premature failure. Therefore, it is crucial to pack
similar batteries together. The conventional approach to screening batteries is based on
their capacity, voltage and internal resistance, which disregards how batteries perform
during manufacturing. In the battery discharge process, real time discharge voltage
curves (DVCs) are collected as a set of unlabeled time series, which reflect how the
battery voltage changes.… More >
