PURPOSE: A hybrid energy storage system and a system managing method are provided to determine an optimum battery current value and an optimum super capacitor current value by minimizing the variation of battery current and a maximum current value. CONSTITUTION: A battery sensing part(160) measures the state information of a battery(110) and transmits to a control part(190). Multiple super capacitor sensing parts(170a~170k) measure the state information of the super capacitors(120a~120k) and transmit to the control part. Multiple load sensing parts(180a~180N) measure or predict the current information of each load(130a ~130N) and transmit to the control part. The control part calculates the optimum battery current value and the optimum super capacitor current value. Multiple DC/DC converters(140) control current supplied to the battery and the super capacitors through a power line.
