Claim:
1. An apparatus for managing energy, comprising: a State-of-Health (SOH) determination unit configured to collect information about energy storage systems and energy facilities that consume or generate energy, and to determine a State of Health (SOH) of each of the energy storage systems based on the information; and an energy distribution unit configured to distribute energy stored in the energy storage system to loads inside a building based on the information and the SOH, wherein the SOH determination unit comprises: a State-of-Charge (SOC) determination unit configured to determine a State of Charge (SOC) based on an input load, output load and voltage of each cell of the energy storage system; and a determination unit configured to determine the SOH based on the SOC, the voltage of the cell, and the temperature of the cell, and wherein the SOC determination unit determines the SOC using the following equation: where SOC init is the SOC in an existing state, dt is the time that has elapsed after the SOC in an existing state was calculated, I is the current flowing through the cell, and Q max is the maximum energy storage capacity of the cell.
