  • Electronic apparatus, battery management system, and battery management method
    Patent number: 5654623
    Abstract: Methods and apparatus to enable electronic apparatuses to display the remaining power of exchangeable batteries at any given time. A battery pack having a battery and an ID generator is attached to an electronic apparatus. The accumulated consumption hours of the battery is stored in a battery information memory for each battery ID. A remaining power detector determines the remaining battery power on the basis of the accumulated consumption hours and displays it on a display unit. Because the remaining battery power is determined based on the consumption hours of a battery, the running hours of a battery can be displayed at any given time.
    Type: Grant
