Patent ID: 8555093

Claim:
A communication device for utilization in a communication network, the communication device comprising: a communication process section for controlling communications in the communication network; a battery for supplying power to the communication process section; a battery control section for controlling the supplying of power to the battery; a first temperature detection section for detecting temperature of a battery housing section housing the battery; a temperature control section for, (A) when the battery is being charged and the temperature detected by the first temperature detection section is not within a predetermined first charging-temperature range, controlling the battery control section to halt the charging of the battery, and (B) when power is supplied from the battery to the communication process section and the temperature detected by the first temperature detection section is not within a predetermined first discharging-temperature range, halting the supplying of power from the battery to the communication process section; and a second temperature detection section for detecting temperature of the battery, wherein the battery control section, when the battery is being charged and the temperature detected by the second temperature detection section is not within a predetermined second charging-temperature range, halts the charging of the battery.
