A CHARGE CONTROL METHOD AND A DISCHARGE CONTROL METHOD FOR AN ELECTRIC STORAGE APPARATUS IS PROVIDED THAT CAN SUPPRESS VARIATIONS IN THE INTER-TERMINAL VOLTAGE OF CAPACITORS WITHOUT USING A PARALLEL MONITOR. ACCORDING TO THE CHARGE CONTROL METHOD OF THE PRESENT INVENTION, AS AN ELECTRIC STORAGE MEANS, A GROUP OF CAPACITORS IS USED THAT INCLUDE 2N (WHERE N IS AN INTEGER OF 2 OR MORE) ELECTRIC DOUBLE LAYER CAPACITORS, FROM FIRST TO 2N-TH ELECTRIC DOUBLE LAYER CAPACITORS, HAVING AN EQUAL ELECTROSTATIC CAPACITY, AND THAT IS CONFIGURED SUCH THAT ADJACENT ELECTRIC DOUBLE LAYER CAPACITORS ARE CONNECTED EITHER IN SERIES OR IN PARALLEL BY A SWITCH AND THE 2N-TH ELECTRIC DOUBLE LAYER CAPACITOR AND THE FIRST ELECTRIC DOUBLE LAYER CAPACITOR ARE CONNECTED IN PARALLEL BY A SWITCH. AMONG THE 2N CAPACITORS CI CONSTITUTING THE ELECTRIC STORAGE UNIT 21, ADJACENT CAPACITORS ARE SEQUENTIALLY SWITCHED FROM A SERIES CONNECTION TO A PARALLEL CONNECTION, OR THE 2N-TH CAPACITOR C2N AND THE FIRST CAPACITOR C1 ARE SWITCHED TO A PARALLEL CONNECTION STATE, WHEREBY VARIATIONS IN THE INTERTERMINAL VOLTAGES OF THE CAPACITORS ARE SUPPRESSED. |
