    • A dye sensitization photoelectric converter with enhanced light absorptance and photoelectric conversion efficiency is provided. A dye sensitization photoelectric converter 10 is chiefly configured of a transparent substrate 1 such as glass, a transparent electrode (negative electrode) 2 composed of a transparent conductive layer such as FTO (fluorine-doped tin(IV) oxide SnO2), a semiconductor layer 3 holding plural kinds of photosensitizing dyes, an electrolyte layer 5, a counter electrode (positive electrode) 6, a counter substrate 7 and a (non-illustrated) sealing medium, etc. As a characteristic of the present invention, the photosensitizing dye is composed of plural kinds of dyes having sufficiently different minimum excitation energy from each other or is composed of plural kinds of dyes to be held in a different steric configuration from each other in the semiconductor layer 3. A porous layer obtained by sintering a fine particle of titanium oxide TiO2 is used as the semiconductor layer 3, an organic electrolytic liquid containing an oxidation-reduction species (redox pair) such as I−/I3− is used as the electrolyte layer 5, and the counter electrode 6 composed of a platinum layer 6b or the like is formed on the counter substrate 7.

    • An SOC-estimation-value-depending gain selection unit multiplies the deviation of an SOC estimation value (last calculated value) relative to an estimated SOC by a correction gain G1 to calculate a correction value. The SOC-estimation-value-depending gain selection unit selects a relatively small correction gain G1 when the SOC estimation value lies in the range in proximity to excessive charging and the SOC estimation value is corrected to a smaller value (toward the SOC control center), and when the SOC estimation value lies in the range in proximity to excessive discharging and the SOC estimation value is corrected to a larger value (toward the SOC control center). Thus, the correction is performed so as to indicate the safe side value for the secondary battery in charge/discharge control when the SOC estimation value is in proximity to excessive charging or excessive discharging.
    • SOC估计值依赖增益选择单元将SOC估计值(最后计算值)相对于估计的SOC的偏差乘以校正增益G1以计算校正值。 SOC推定值依赖增益选择部,在SOC估计值位于与过充电接近的范围内时,选择相对较小的校正增益G1,将SOC估计值修正为较小的值(朝向SOC控制中心) ,并且当SOC估计值位于与过度放电接近的范围内时,并且将SOC估计值校正到较大的值(朝向SOC控制中心)。 因此,当SOC估计值接近过充电或过度放电时,执行校正以指示充电/放电控制中的二次电池的安全值。
