The pack uses three parallel pairs of cells in series to make 10.xx volts with low and medium taps going to the BMS.

Replacing lithium cells

Open the battery and measure the voltage of all cells. If one (or two ..) is lower, it could have (slightly) higher self-discharge than the others, having been discharged over the years. If that''s the case, you could try to charge only that cell(s) to the same level as the other cells. If all have the same voltage, the battery most likely is dead.

Individual Cells Replacement Concept in Lithium-ion Battery

Imagine a string of decorative lights. If one bulb blows out, the entire string can go dark. Now, you can either replace the entire string, which seems wasteful considering only one bulb is faulty, or you can find the one troublesome bulb and replace it, bringing the entire string back to life. This analogy isn''t far from the challenges we face with lithium-ion battery packs.Lithium-ion

6 FAQs about [Replace some cells in lithium battery pack]

Should a battery pack be replaced?

If a relatively new pack has only one defective cell and a replacement is located, exchanging the affected cell makes sense. With an aged battery, however, it’s best to replace all cells. Mixing new with old causes a cell mismatch that has a short life. In a well-matched battery pack all cells have similar capacities.

Can a battery pack be reconfigurable for individual cell replacement?

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 ].

Can Li-ion batteries be replaced?

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.

What are the replacement strategies for battery packs?

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.

Can cell replacement prolong the life of battery packs?

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.

Can lithium ion batteries be reused?

The second scenario for reuse of lithium ion battery packs examines the problem of assembling a pack for less-demanding applications from a set of aged cells, which exhibit more variation in capacity and impedance than their new counterparts.
