    • PROBLEM TO BE SOLVED: To maintain the EDLC voltage in a standby state prepared for regenerative power absorption at a value near to that in the initial stage of installation.SOLUTION: When the EDLC voltage is below a lower limit set value at which discharging is possible, EDLC voltage constant control of a power converter starts an action in a restricting action starting step 41. The time from the restricting action start to the time when the EDLC current becomes a predetermined value or below is measured in a time measuring step 42, and whether the measured time has exceeded the value two times higher than a present value set at the initial stage is determined in a first determining step 43. When it is determined that the measured time has exceeded the value two times higher than the value set at the initial stage based on the determination result in the determining step 43, the determination result is transferred to a second determining step 44. In the second determining step 44, the voltage drop ΔV(R×I) by EDLC internal resistance R is determined to have reached the value two times higher than the value set at the initial stage, and the EDLC internal resistance is determined to have increased. Based on the determination result, EDLC charging finishing current in stopping charging is adjusted to a "1/2 times" value of the value set at the initial stage in a current adjusting step 45.

    • PROBLEM TO BE SOLVED: To provide stable regenerative control by preventing occurrence of hunting caused by charge voltage control with a power storage medium due to a hanging characteristic and a regenerative restriction operation of an electric vehicle.SOLUTION: If a trigger voltage becomes a charge start voltage or higher by a regenerative current from an electric vehicle, a charge voltage of a power storage device is raised with a hanging characteristic corresponding to a regenerative current restriction characteristic of the electric vehicle, and a regenerative current restriction amount of the electric vehicle is increased by the trigger voltage rise to prevent regenerative invalidation.

    • PROBLEM TO BE SOLVED: To prevent a feeder failure due to overvoltage and charge an electric double-layer capacitor up to the maximum possible level. SOLUTION: In the method of charge control, a current command value obtained by inputting a current command value output from a PI amplifier 23 to a limiter 24 to be controlled is compared with a new current command value refined by a filter 34 for refining a current command value in consideration of internal resistance of an electric double-layer capacitor using a comparator 32, and outputs a smaller current command value as a charging current command value. A deviation output between the charging current command value output from the comparator 32 and a detected value of the charging current value of the electric double-layer capacitor is obtained. The output is input to an amplifier 28 for controlling a duty ratio through a PI amplifier 26 after obtaining a PI control output for determining a duty of a bidirectional chopper means. A PWM signal corresponding to the duty ratio is created in a CMP creation part 29 from the amplifier 28. From the PWM signal and a condition signal when regenerative electric power is generated, a gate signal is obtained. COPYRIGHT: (C)2011,JPO&INPIT
