An alternative strategy would be making the battery pack reconfigurable for individual cell replacement, so that only less healthy cells would be replaced with newer cells, instead of replacing the entire battery pack [ 17 ].
A battery voltage model and a battery degradation model were used to set up the simulation framework. The simulation stochastically generated 10 sets of runs, with each set consisting of 80 LFP cells where 40 cells were put in a battery pack and the other 40 cells were utilized as additional cells for replacement.
The 40-cell packs (2.64 kWh) represent standard battery packs used in various real-world applications. The other 40 cells would be used when the cells in the initial pack needed replacement. The battery packs simulated were subjected to discharge and charge cycles of 1 C between 20% and 80% average SOC. The simulation started at 80% for each cell.
It was found that the cell replacement method can increase the total number of cycles of the battery packs, effectively prolonging the lifespan of the packs. It is also determined that this approach can be more economically beneficial than the current approach of simple pack replacement.
The concept of cell replacement in Li-ion battery packs is relatively new, and despite some recent efforts to investigate this concept, the feasibility, in terms of economics and design, of cell replacement has not been well-studied.
The replacement strategies considered two scenarios. The first scenario, the replacement of an early life failure, addresses an important open question for maintenance of battery packs. The traditional approach in pack maintenance is to replace all cells at once to control the mismatches.
''Individual Cells Replacement Concept'' in batteries suggests that, much like replacing a single blown-out bulb, we can replace individual faulty or underperforming cells in a battery pack.
