    • A smart battery device (10) which provides electrical power and which reports predefined battery parameters to an external device having a power management system, includes: at least one rechargeable cell (26) connected to a pair of terminals (31 and 32) to provide electrical power to an external device (28) during a discharge mode, and to receive electrical power during a charge mode, as provided or determined by remote device (28); a data bus for reporting predefined battery identification and charge parameters to the external device; analog devices for generating analog signals representative of battery voltage and current at the terminals, and an analog signal representative of battery temperature at the cell; a hybrid integrated circuit (IC) (32) having a microprocessor (50) for receiving the analog signals and converting them to digital signals representative of battery voltage, current and temperature, and calculating actual charge parameters over time from the digital signals, the calculations including one calculation according to the following algorithm: CAPrem = CAPFC - SIGMA Id DELTA td - SIGMA Is DELTA t + SIGMA ELEMENT cIc DELTA tc wherein ELEMENT c is a function of battery current and temperature; and Is is a function of battery temperature and CAPFC. Superimposed on this equation is reset logic, that self corrects the CAPFC with a capacity calculation at each full charge (EOC) and each end of full discharge.

    • A metal support disk (10) useful in sealing an electrochemical cell exerts a resilient outward radial force against the seal to assure seal integrity over a wide temperature range and exerts an upward force against an adjacent metal end cap terminal (100) to assure continued mechanical and electrical contact with the terminal. The support is a stepped disk having a centrally located, shallow, cylindrical pill-box (12) with the bottom (22) of the pill-box (12) extending radially outward into an annular ring (24). A spring means in the form of an S-shaped rim (26) extends down from the periphery of the ring (24) terminating at its bottom in an outward extending flange (28). The edge of the flange (28) presses a plastic seal member against the inside wall.
    • 可用于密封电化学电池的金属支撑盘(10)向着密封件施加弹性向外的径向力,以确保在宽的温度范围内的密封完整性,并向邻近的金属端盖端子(100)施加向上的力,以确保持续的机械 并与终端电接触。 支撑件是具有中心定位的浅圆柱形药丸盒(12)的阶梯盘,其中药丸盒(12)的底部(22)径向向外延伸成环形圈(24)。 形成S形边缘(26)的形式的弹簧装置从环(24)的周边向下延伸,在其底部终止于向外延伸的凸缘(28)中。 凸缘(28)的边缘将塑料密封件压靠在内壁上。
