Abstract

The router device acquires detected temperature T from a thermistor provided inside the battery box containing secondary battery that provide the power supply, and if the detected temperature T is not smaller than a threshold value Th1, produces flashing display of an LED to alert the user. If the detected temperature T is not smaller than a threshold value Th2 additionally, supply of power to the CPU of the router device is subsequently interrupted. In this way, in a router device powered by a secondary battery, diminished functionality of the secondary battery due to elevated temperature may be prevented.

Claims

1. A router device comprising:

a battery connection portion adapted to connect to secondary battery and to receive supply of power from the connected secondary battery to the router device;

a power control portion adapted to control conditions of supply to the router device of power that has been received from the secondary battery; and

a temperature detection portion adapted to detect temperature in the vicinity of the secondary battery;

wherein the power control portion interrupts supply of power to the router device when the detected temperature is not smaller than a first threshold value.

2. The router device according to claim 1 further comprising an alert portion adapted to alert the user of the router device if the detected temperature is not smaller than a second threshold value, prior to interruption of supply of power by the power control portion.

3. The router device according to claim 2, wherein as one process for providing the aforementioned alert the alert portion emits light from a light-emitting device furnished to the alert portion.

4. The router device according to claim 2, wherein as one process for providing the aforementioned alert the alert portion sends an e-mail alert to a destination which is a preregistered e-mail address.

5. The router device according to claim 2, wherein as one process for providing the aforementioned alert the alert portion produces a pop-up display on the display screen of a prescribed information processing device connected to a local area network to which the router device is also connected.

6. The router device according to claim 1 further comprising:

a voltage detecting portion adapted to detect output voltage of the secondary battery; and

a correction portion adapted to correct detection characteristics of the voltage detecting portion, using temperature detected by the temperature detection portion.
