It was then decided to discharge the battery to 50% SOC by a constant 0.1A current. It took 30.12 hours to discharge the battery to half. What is the capacity of the battery, given SOC is sampled initially and at 50%? Question 4 The charging process of a battery is shown in Figure 1. Assume that the battery was empty at start (i.e) time = 0 hr. Given that the SOC at the end of charging process (i.e) at time = 10 hrs is 0.125, what is the capacity of the battery at end of this process? (Note : Be mindful of the units of time and current used) 21 20 23 24 5.839Ah 6.024Ah 6.145Ah 5.987Ah
