    • In an energy storage device, a charging circuit is electrically coupled to the energy storage section. A first comparator is electrically coupled to an energy storage section, and its output is inverted when voltage Vc of the energy storage section reaches first predetermined voltage Vc1. A second comparator is electrically coupled to the energy storage section, and its output is inverted when voltage Vc of the energy storage section reaches second predetermined voltage Vc2. A control circuit is electrically coupled to the first comparator and the second comparator. The control circuit obtains period tm from inversion of the output of the first comparator to the output of the second comparator. Capacitance C of the energy storage section is calculated based on this period tm and voltage change width ΔVc between the first predetermined voltage Vc1 and the second predetermined voltage Vc2.

    • 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.
    • 使用该装置的A / D转换装置和车辆供电装置在纠错之前计算多个参考电压的误差和参考误差。 每个参考误差被应用于数字输出范围,该数字输出范围除以与参考电压相对应的数字输出。 在计算中,当相邻参考电压获得的误差具有相同的符号时,将参考误差确定为在相邻参考电压下获得的误差的平均值; 另一方面,当相邻参考电压获得的误差具有不同的符号时,基准误差被确定为零。 该装置通过从对应于模拟输入电压的数字输出中减去应用于包括数字输出的数字输出范围的参考误差来提供校正的数字输出。
