Abstract: 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 - ΣIdΔtd - ΣIsΔt + Σ⊂cIcΔtc wherein ⊂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.

Abstract: A battery pack and a method of operating a battery system. The battery pack includes a rechargeable battery and a processor for monitoring the battery during charging and discharging. The processor receives data values representing the battery voltage, temperature and current, and the processor performs a series of calculations using those data values. The processor has normal, standby and sleep modes. In the normal mode, the processor performs the series of calculations at first regular cycles, and in the standby mode, the processor performs the series of calculations at second regular cycles, which are longer than the first cycles. Preferably, the processor enters the standby mode when the battery current falls below a predetermined current level, and the processor enters the sleep mode when the battery voltage falls below a first predetermined voltage level. Also, the processor exits the sleep mode when the battery voltage rises above a second predetermined voltage level higher than the first predetermined voltage level.
