From 6 to 8 s, a shortage of 2 A in the network is responded to by the battery within 1 s due to the high battery charge level, but from 8 to 10 s, a two-ampere change (from 2 A to 4 A) is compensated for by the battery within 2 s. The reason for this is the low battery charge level and the higher current range of the network shortage.
