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.
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. This approach is clearly untenable for very large battery packs.
The cell replacement strategies investigation considers two scenarios: early life failure, where one cell in a pack fails prematurely, and building a pack from used cells for less demanding applications.
To simulate a failure in the battery management system, the cells were left overnight to discharge through a set of resistors used for cell balancing, allowing the terminal voltages to drop considerably below the minimum value required by the cell manufacturer.
The single-cell apparatus was a Maccor 4600 battery test system, used for initial cell characterization, pre-aging of individual cells, and periodic monitoring of the cells subjected to pack-level cycling. Additional details on the test procedure are provided in the Supplementary Materials. The test stand for pack testing is shown in Figure 1 a.
Several modules together with additional electrical periphery (e-parts like battery management etc.) form a complete traction battery. The research gap addressed is the concept of a remanufacturing process for LIBs down to cell level and the associated changes regarding design and assembly of the components.
The battery pack used in Figure 3 is typical of that found in many other battery-operated devices. It consists of several battery cells connected in series plus a Battery …

The market share of electric vehicles (EVs) increases rapidly in recent years. However, to compete with internal combustion engine vehicles, some barriers in EVs, …
By dividing the cells of a battery pack in modules which can be replaced, the expected life of a module can be longer than the battery pack life by a factor 1 / (n/m)(1 / β), which makes a …
The potential to extend the lifetime of Li-Ion batteries and to restore the state of health (abbreviated SOH) to almost 100% by exchanging a small number of cells has been …
The study employed two test stands: one for single-cell testing and the other for battery pack evaluations. The single-cell apparatus was a Maccor 4600 battery test system, used for initial cell characterization, pre …
