摘要： PROBLEM TO BE SOLVED: To accurately determine the deterioration of a rechargeable battery due to irregular variation in load.
SOLUTION: Charge and discharge current I of the rechargeable battery and voltage V between terminals are inputted (S104). When the inputted charge and discharge current I is approximately zero with the specified variation, a load history P as an indication showing the history of load on the rechargeable battery corresponding to the charge and discharge current I is calculated (S106 to S108). Voltage V when the load history P is a specified recharging history is set as polarization voltage Vc. At the same time, voltage V when the load history P is a specified discharging history is set as polarization voltage Vd (S110 to S 118). Then, when the voltage difference ΔV as a variation of polarization voltages Vc and Vd exceeds threshold Vref, the rechargeable battery is determined as deteriorated (S122). When a uniform standard is set as load history P, since the voltage difference ΔV when the load history P is at that standard directly reflects the degree of deterioration of the rechargeable battery, the deterioration can be determined more accurately.

摘要： PROBLEM TO BE SOLVED: To suppress a peak value of a recovery surge voltage from becoming large. SOLUTION: A power supply device includes: a battery 29; a film capacitor 21; transistors 23, 25; gate resistors 24, 26; a flywheel diode 22; a current sensor 27; and a control unit 30. When a load current detected by the current sensor 27 is equal to or lower than a prescribed value, the control unit 30 outputs an on-signal to one of transistors 23, 25 (for example, only the transistor 23), and when the load current is larger than the prescribed value, the control unit outputs on-signals to both the transistors 23, 25. By this arrangement, the peak value of the recovery surge voltage can be suppressed from becoming large without using a large gate resistor, and a loss caused by the gate resistor can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a method to judge the deteriorated condition of a secondary battery by repeating the charging and discharging frequently. SOLUTION: The judging method for deterioration of a secondary battery consists of such procedures that a unitary charge-discharge cycle consisting of current discharge, pause after interruption of discharging, charging of current, and pause after interruption of charging is performed to the secondary battery for a certain period of time in one cycle or a plurality of cycles continuously, the voltage difference in the final charge-discharge cycle between at interruption of discharging and at interruption of charging is determined, and that the obtained voltage difference is compared with the preset value to serve for judgement of the deteriorated condition of the secondary battery. Because measurement of the polarization voltage is made by subjecting the battery to charging and discharging in accordance with the unitary charge-discharge cycle for a certain specified period of time, it is possible to perform judgement in a short time.
