    • A photovoltaic-charged secondary battery device has a cylindrical core, a flexible photoelectric transducer sheet extractably rolled on the core, a chargeable/dischargeable storage battery, and a control circuit for controlling the charging and discharging operations of the storage battery. The photovoltaic-charged secondary battery device with the photoelectric transducer sheet fully rolled on the core generally exhibiting a substantially cylindrical form. The photovoltaic-charged secondary battery device further has a polymeric cover film formed on the light-receiving surface of the photoelectric transducer sheet. The polymeric cover film improves the durability of the photoelectric transducer sheet against repeated bending and sliding actions caused on the photoelectric transducer sheet. The photoelectric transducer sheet may be so arranged that, when the photoelectric transducer sheet is rolled on the core, the light-receiving surface faces outward of the roll. The photovoltaic-charged secondary battery device may have a cylindrical peripheral wall coaxial with the core and defining therebetween an annular space for accommodating the photoelectric transducer sheet rolled on the core. The photoelectric transducer sheet is retractable into and extractable from the annular space through a slit formed in the cylindrical peripheral wall member. The cylindrical peripheral wall member is rotatable relative to the core, so that the photoelectric transducer sheet can be retracted into the annular space and rolled on the core as the cylindrical peripheral wall member is rotated. The cylindrical peripheral wall member may have a plurality of projections formed on the inner surface thereof. The photovoltaic-charged secondary battery device may have a temperature-responsive mechanism operable to disconnect the storage battery from the electrical connection or to move the storage battery from a predetermined position.
    • 光伏充电二次电池装置具有圆筒形芯,可提取地卷绕在芯上的柔性光电传感器片,可充电/可放电的蓄电池,以及用于控制蓄电池的充电和放电操作的控制电路。 具有光纤换能片的光伏充电二次电池装置通常呈现出基本圆柱形的形式。 光电二次电池装置还具有在光电转换片的受光面上形成的聚合物覆盖膜。 聚合物覆盖膜提高光电传感器片的耐久性,防止在光电传感器片上引起的反复弯曲和滑动。 光电传感器片可以布置成使得当光电转换片在芯上滚动时,光接收表面面向卷的外侧。 光伏充电的二次电池装置可以具有与芯部同轴的圆柱形周壁,并在其间限定用于容纳在芯上滚动的光电传感器片的环形空间。 光电传感器片通过形成在圆筒形周壁构件中的狭缝可缩回到环形空间内并可从其中取出。 圆筒形周壁构件可相对于芯部旋转,使得当圆筒形周壁构件旋转时,光电换能器片材可以缩回到环形空间中并在芯体上滚动。 圆筒形周壁构件可以具有形成在其内表面上的多个突起。 光伏充电的二次电池装置可以具有温度响应机构,其可操作以将蓄电池与电气连接断开或将蓄电池从预定位置移动。
