    • A battery device for an electronic apparatus includes a rechargeable secondary battery, a fuel cell, and a run time computing unit receiving, from the secondary battery, data representative of a voltage versus residual-capacity characteristic of the secondary battery, and receiving, from the fuel cell, data representative of a residual capacity of the fuel cell. The computing unit determines data representative of a residual capacity and a run time of the secondary battery in accordance with the data representative of the voltage versus residual-capacity characteristic and with supply voltage and supply current of the secondary battery, determines a run time of the fuel cell in accordance with the data representative of the fuel cell residual capacity and with supply current of the fuel cell, and estimates which of power capacities of the secondary battery and fuel cell reaches predetermined residual capacities earlier. If it is estimated that the power capacity of the fuel cell reaches its predetermined residual capacity earlier, the computing unit determines a run time of the battery device, in accordance with the data representative of the secondary battery residual capacity, the data representative of the fuel cell residual capacity, and the supply currents of the secondary battery and fuel cell. The computing unit supplies data representative of the thus determined run time of the battery device to a power management unit of the electronic apparatus. Thus the battery device including the fuel cell can be used with a conventional electronic apparatus.
    • 电子设备的电池装置包括可再充电二次电池,燃料电池和运行时间计算单元,其从二次电池接收表示二次电池的电压与剩余容量特性的数据,并从 燃料电池,表示燃料电池的剩余容量的数据。 计算单元根据表示电压对剩余容量特性的数据和二次电池的电源电压和电源电流来确定表示二次电池的剩余容量和运行时间的数据,确定二次电池的运行时间 燃料电池根据表示燃料电池剩余容量的数据和燃料电池的供给电流,并且估计二次电池和燃料电池的功率容量哪一个更早地达到预定的剩余容量。 如果估计燃料电池的电力容量早于其预定的剩余容量,则计算单元根据代表二次电池剩余容量的数据确定电池装置的运行时间,代表燃料的数据 电池剩余容量和二次电池和燃料电池的供电电流。 计算单元将表示如此确定的电池装置的运行时间的数据提供给电子设备的电源管理单元。 因此,包括燃料电池的电池装置可以与传统的电子装置一起使用。
