| description | There is provided a charge controller capable of charging a capacitor while suppressing the progress of deterioration of the capacitor without unnecessary charge/discharge of the capacitor. The charge controller includes a voltage sensor 133 that detects the voltage of a capacitor 101, a current sensor 135 that detects the charge/discharge current of the capacitor 101, a battery ECU 123 that estimates the SOC of the capacitor 101 based on the detected voltage, and a management ECU 117. The management ECU 117 calculates the charge/discharge amount from the start of charging of the capacitor 101 by integrating the charge/discharge currents detected by the current sensor 135 and controls the charging of the capacitor 101 based on the estimated SOC and the calculated charge/discharge amount. The management ECU 117 updates and sets the estimated SOC to an actual use upper limit SOC based on the state characteristics of the capacitor 101. |
