How does charging current affect battery efficiency?

It is also noticed that, the efficiency of the battery sharply increases when the charging current surpasses the discharge current, it is explained using Peukert’s law which states that, “As the rate of discharge of the battery increases, the battery's available capacity decreases”.

How does current rate affect charging capacity?

The greatest variance is approximately 36% of the rated capacity, which shows that the current rate has a greater impact on the charging capacity. As the charging rate increases, the faster the active material reacts, the faster the battery voltage increases, and the energy loss generated increases.

Why do batteries take so long to charge?

It was then inferred from this work that the very long time required to charge batteries at lower rates is not only due to the smallness of the magnitude of the current per say but due to the fact that at such low currents, the charging process is ineffective.

What happens if charging current exceeds discharge current?

As concerns the fact that efficiency of the battery sharply increases when the charging current surpasses the discharge current, when the charging current increases above the discharge current, the rate of energy storage significantly increases while the discharge current remains the same.
