Emulation of the Operation of a Lithium-Ion Batteries Pack in Healthy and Faulty Condition

摘要

The need for an efficient way to store energy is a key point for the deployment of electrical systems. The need for high power and high energy makes it necessary to increase the number of cells in the packs and to develop adequate battery system management. Therefore, it is important to be able to study the correct management of energy in both healthy and faulty conditions, if some of the cells fail. This paper presents the emulation of a battery pack, cell by cell. An electrical model has been developed in a Matlab/Simulink? environment and identified through experimental data. It is implemented in dSpace Mid-Size. Healthy operation and degraded mode are then emulated.
