Battery driving device, load control method, integrated circuit and load control program |
摘要 |
A battery-driven device extends an operating time of a battery (a secondary battery). A battery control unit included in the battery drive-device stores therein one or more voltage thresholds, and detects a sharp voltage drop that occurs immediately after the start of discharging of a battery that is fully charged, based on the current and voltage of the battery and the stored voltage thresholds. Upon detecting a sharp voltage drop, the battery control unit decreases power consumption of the battery.
