Abstract
an electric vehicle battery pack may employ cells
connected electrically in parallel to meet energy and power
requirements. For the battery management system, cells
connected in parallel are often treated as a single larger
component. However, research has identified that the state of
charge and cell current may not be equal due to differences in
capacity, impedance and cell temperature. In this paper, the
authors develop a parallel cell model validated against
experimental data. The model is used to evaluate cell energy
variation and the impact this can have on the design of highly
parallelized battery systems.
