Embodiment approach

[0112] In the above-mentioned embodiment, the weighted value corresponding to the temperature shown in FIG. 4 and FIG. 7 is integrated by the integrating counter 102, and power control is performed using the integrated value.

[0113] The above integrated value is obtained by calculating the weighted values ​​shown in Figure 4 and Figure 7 by the integrated counter 102 according to a certain sampling time (every 5 seconds in Figure 4 and every 10 seconds in Figure 7 ). .

[0114] However, in the present invention, the calculation method of the above-mentioned integrated value is not limited to the above-mentioned calculation method. It is also possible to change the sampling time without changing the weighted value corresponding to each temperature, so that the accumulated value of the sampling times is used as the integrated value.

[0115] For example, the higher the temperature, the shorter the sampling time can be set. When this solution is adopted, the damage to the hum...

Abstract

A power control unit (100) is provided with: a temperature detecting unit (101), which detects the temperature of a battery unit (4); and an integration counter (102), which integrates a value allocated to the temperature of the battery unit (4), said temperature having been detected by the temperature detecting unit (101). The power control unit (100) reduces power to be supplied to an LCD display unit when an integrated value integrated by means of the integration counter (102) exceeds a predetermined value.

Description

technical field [0001] The invention relates to a power control device for controlling the power supplied to a device. Background technique [0002] In recent years, devices such as mobile phones and information processing terminals have become more multifunctional. However, as the size of the devices has increased and the battery power has increased, the surface temperature of the devices during use has also increased. [0003] In particular, these devices are often held directly by users for extended periods of time, and some people have suffered cryogenic burns due to the surface temperature. [0004] In response to this, various techniques for preventing low-temperature burns caused by equipment have been proposed. [0005] For example, Patent Document 1 discloses a technology for controlling power and temperature by triggering power control with a given temperature threshold. [0006] In addition, Patent Document 2 discloses a power control technology for preventing l...
