How do I calculate the lithium-ion battery size for a varying load?

To calculate the battery size for a varying load which requires I1 in the interval t1 and I2 in the remaining time:

  1. Estimate the average load current โ€” Iav = (I1 ร— t1 / t) + (I2 ร— [t - t1 / t]).
  2. Substitute I = Iav in the equation for battery capacity of lithium-ion. B = 100 ร— I ร— t / (100 - q) where B is the battery capacity, I is the load current, t is the duration of power supply, and q is the percentage of charge which should remain in the battery after the discharge.
