Abstract
It is a power control unit that can perform preventing a secondary battery from generating heat and preventing power supply from being suddenly shut off. Supply of power from a secondary battery (13) to a system unit (11) is controlled by a power control unit (12). At this time, the power control unit (12) successively monitors a cell temperature of the secondary battery (13), and requests the system unit (11) to switch to a power saving mode when the cell temperature exceeds a predetermined alarming temperature which is preset.
Claims9
A power controller provided in an apparatus operated by power supplied from a secondary battery, said power controller controlling the power supplied from the secondary battery,
- wherein, when the temperature of battery cells in the secondary battery exceeds a preset temperature, said power controller requests the apparatus to switch to an operation in a power saving mode.
A power control method for controlling power supplied from a secondary battery provided in an apparatus, comprising:
- a cell temperature detecting step for detecting the temperature of battery cells in the secondary battery;
- and
- an operating mode control step for, when the temperature detected in said cell temperature detecting step exceeds a preset temperature, requesting the apparatus to switch to an operation in a power saving mode.
An information processor operated by power supplied from a secondary battery, comprising
- a power control unit which, when the temperature of battery cells in the secondary battery exceeds a preset temperature, requests the apparatus to switch to an operation in a power saving mode.
A power control program for controlling power supplied from a secondary battery provided in an information processor, said power control program executing:
- a cell temperature detecting process for detecting the temperature of battery cells in the secondary battery;
- and
- an operating mode control process for, when the temperature detected in said cell temperature detecting process exceeds a preset temperature, requesting a predetermined part of the information processor to switch to an operation in a power saving mode.
