What is Lithium Battery C-rate and How to Calculate it?
Understanding C-rate in Lithium Batteries. When dealing with lithium batteries, the C-rate is a crucial factor that dictates how fast a battery charges or discharges relative to its capacity.If a battery with 1000mAh capacity takes one hour to charge or discharge completely, its C-rate is 1C; if it takes two hours, it''s 0.5C.
How to Calculate the time of Charging and Discharging of battery?
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For …
Maximum Cell Discharge Capability
We can also calculate the maximum current we can draw taking the cell down to the minimum voltage: 2.5V = 3.7V – I x 0.025Ω. Rearranging this we can calculate the current: I = (3.7V – 2.5V) / 0.025Ω = 48A. These numbers are quite typical of a 5Ah NMC cell. Peak discharge is around 10C.
