AI Customer ServiceDuring the grading process, data is collected from each detection point on the battery through computer management. The data is then analyzed to determine the size of the battery’s capacity and internal resistance, allowing the quality level of the battery to be determined.
By grading and grouping lithium-ion cells based on their internal resistance and capacity, the battery packs produced are more reliable, efficient, and longer-lasting. Therefore, it is essential to conduct cell grading for all lithium-ion batteries, including Lithium Iron Phosphate Batteries (LiFePO4).
B grade cells have a higher rate of capacity fade as compared to A grade cells. Life – Lithium-ion cells are known for their long-lasting life. The cells degrade and their energy holding capacity reduces over time but they last for a long time, unlike Lead Acid batteries which experience sudden death.
The data is then analyzed to determine the size of the battery’s capacity and internal resistance, allowing the quality level of the battery to be determined. Following the initial grading, batteries should remain stationary for at least 15 days, during which time any underlying quality issues will surface.
Another reason is the pressure from the OEMs to supply battery packs at an aggressive price. A technical way to know if the cell is B grade is to charge-discharge the cell for a suitable number of cycles depending on the cell capacity, chemistry, form factor and intended application of the battery pack and look at the data.
1. Capacity Capacity, often measured in milliamp-hours (mAh) or amp-hours (Ah), represents the total charge a battery can store. During grading, cells with closely matched capacities are grouped together, ensuring consistent performance in battery packs.
