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： 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： A detector for detecting a state of an electrical storage device includes capacitor blocks formed of a capacitor-voltage equalizing circuit and a capacitor-voltage detecting circuit both coupled to respective capacitors, and a capacitor-block state outputting circuit outputting states of the capacitors by using the signals supplied from the capacitor-voltage detecting circuits. The signals from the capacitor-voltage detecting circuits are transmitted via an optical switch, which works as an electrical indirect coupler, to the capacitor-block state outputting circuit. This structure allows isolating high-voltage oriented wirings completely from signal oriented wirings, so that high reliability can be ensured.
