电压式电池剩余电量检测装置及方法和利用该装置和方法的便携式电子设备
摘要：
本发明涉及一种电压式电池剩余电量检测装置及方法和利用该装置和方法的便携式电子设备，尤其涉及适合根据电池电压准确检测电池剩余电量的电压式电池剩余电量检测装置及方法。本发明的电压式电池剩余电量检测方法包括：输入电池放电电压的步骤；将上述电池放电电压与临界电压进行比较的步骤；电池的放电电压低于临界电压时，将电池的剩余电量设定″0″的步骤；电池的放电电压高于临界电压时，放大电池放电电压的变化幅度，将放大的放电电压设定为电池的剩余电量的步骤。本发明通过放大电池放电电压的变化幅度，可准确地检测出电池组的剩余电量。
摘要（英）：

Residual charge in a battery is measured based on a discharge voltage from the battery. A device for measuring the residual charge in the battery includes a fluctuation width amplifier configured to amplify a fluctuation width of a discharge voltage from the battery in excess of a threshold voltage. The device includes a display module configured to display the discharge voltage amplified by the fluctuation width amplifier. The discharge voltage amplified by the fluctuation width amplifier corresponds to the residual charge in the battery. The residual charge in the battery may be determined based on the discharge voltage and the application load data due to an operative application program.
