Abstract: The features of the operation environment of LiFePO4 Liion battery pack in the DC system of substation were analyzed. The estimation method of SOC of LiFePO4 Liion battery pack in different working phases was given, and the relevant method of equalizing charge for the battery pack was given too.

Key words: substation, LiFePO4 Li-ion battery, state of charge(SOC), equalization
