Abstract
The future intra-terminal temperature is estimated on the basis of present intra-terminal temperature and a present service state of the terminal. In addition, the charging of the battery unit is controlled on the basis of the estimated future intra-terminal temperature.
Claims20
A communication device which operates by a power supply from a battery unit charged by a battery charger, comprising:
- intra-device temperature estimation means which estimates future intra-device temperature on the basis of present intra-device temperature and a present service state of the communication device;
- and
- charge control means which controls charging of the battery unit on the basis of the future intra-device temperature estimated by the intra-device temperature estimation means;
- wherein said present service state of the communication device is determined from at least a detected voltage and a consumption current.
A method of controlling heat generation of a communication device which operates by a power supply from a battery unit charged by a battery charger, comprising:
- estimating future intra-device temperature on the basis of present intra-device temperature and a present service state of the communication device;
- and
- controlling charging of the battery unit on the basis of the future intra-device temperature estimated;
- wherein the present service state of the communication device is determined from at least a detected voltage and a consumption current.
A method of controlling heat generation of a communication device which operates by a power supply from a battery unit charged by a battery charger, comprising:
- estimating intra-device temperature after a predetermined setup time after starting charging on the basis of current intra-device temperature and a current service state of the communication device, and
- controlling charging of the battery unit on the basis of the intra-device temperature after the predetermined setup time estimated
- wherein said current service state of the communication device is determined from at least a detected voltage and a consumption current.
A communication device which operates by a power supply from a battery unit charged by a battery charger, comprising:
- a temperature monitor operable to estimate future intra-device temperature on the basis of present intra-device temperature and a present service state of the communication device;
- and
- a charge controller operable to control charging of the battery unit on the basis of the future intra-device temperature estimated by the temperature monitor;
- wherein said present service state of the communication device is determined from at least a detected voltage and a consumption current.
