Abstract
This system provides an energy storage system that efficiently stores generated electricity by directly connecting to unstable power generation devices such as renewable energy sources. [Solution] The energy storage system includes input terminals Vin+ and Vin- into which power is input from a power generator, two or more capacitors 111 to 114 that store charge by applying voltage, batteries 211 to 214 that store energy by chemical reaction, output terminals Vout+ and Vout- that output the power stored in the batteries, a first switch 3 that switches whether to supply power from the input terminals to the capacitors or to the batteries, a second switch 4 that switches whether to supply power from the input terminals or to the batteries, a third switch 121 to 124, 131 to 134, 141 to 143 that switches whether to connect two or more capacitors in parallel or in series, and a voltmeter 5 that measures the voltage of the power input to the input terminals.
