摘要： A power supply device has a capacitor unit in which capacitors are interconnected in series, a charging unit for charging the capacitor unit at a constant current, a detecting unit for detecting voltage on the high potential side of each of the capacitors, a determining unit for determining the existence of an abnormality based on the voltage detected by the detecting unit. The determining unit determines the abnormality when the difference between respective voltages on the high potential sides of some adjacent capacitors exceeds upper-limit voltage value Va, when the difference is lower than lower-limit voltage value Vb, or when a voltage is negative.

摘要： A vehicle power supply device has a capacitor unit including capacitors storing auxiliary power; a temperature sensor; a charge circuit; a capacitor-unit current detector; a capacitor-unit voltage detector; a controller; a storage; and a determination unit. The determination unit determines the degradation level of the capacitor unit based on at least one of an internal resistance standard value and a corrected calculated value of capacitance.

摘要： The A/D conversion apparatus and the vehicle power-supply device using the apparatus calculate errors at a plurality of reference voltages and reference errors prior to error correction. Each reference error is applied to a digital-output range that is divided by digital output corresponding to the reference voltages. In the calculation, when the errors obtained at adjacent reference voltages have same signs, the reference error is determined as an average of the errors obtained at adjacent reference voltages; on the other hand, when the errors obtained at adjacent reference voltages have different signs, the reference error is determined to be zero. The apparatus provides a corrected digital output by subtracting the reference error—which is applied to the digital-output range including the digital output—from the digital output corresponding to analog input voltage.

摘要： In a voltage monitor that measures voltages applied to the terminals of each of a plurality of capacitors constituting a storage section, the each voltage applied to a connecting point between terminals of the capacitors in charging operation, is divided by resistors and the divided voltage is fed into a selector switch. The resistance values used for dividing the each voltage are determined in advance so that a short-circuit between adjacent input terminals of the selector switch allows the divided voltage to have a voltage shift remarkably larger or smaller than the divided voltage obtained under the normal charging operation.

摘要： A charging apparatus suppresses rise in temperature of an internal chip of a charging element. The output signal obtained from a current detecting portion for detecting charging current to a capacitor and from a voltage detecting portion for detecting a difference between a voltage (VC) of capacitor and a voltage corresponding to DC power supply is integrated by integrator. The charging is carried out by controlling power of a charging element to a predetermined value using an output signal of the integrator and at a time near the completion of the charging, the charging element is controlled by constant-voltage-control-circuit so as to charge the capacitor up to a predetermined voltage. Consequently, the maximum temperature inside the charging element is reduced, thereby providing a charging apparatus with high reliability.
