[0040] The simulation module 2 is fixed on the battery 1 and is located in a preset area centered on the center of the battery 1, for simulating the heating process of the battery 1;

[0041] The control module 3 is electrically connected to the analog module 2 , and the control module 3 is electrically connected to the charging and discharging circuit 4 of the battery 1 , and is used to control the current flowing through the charging and discharging circuit 4 according to the heating process of the battery 1 .

[0042] During the use of the current batt...

Embodiment 2

[0057] Such as image 3 As shown, the embodiment of the present disclosure provides a battery temperature measurement and control method, the method includes:

[0058] In step 201, the heating process of the battery is simulated.

[0059] In an exemplary embodiment of the present disclosure, by setting the analog module in a preset area centered on the center of the battery, when the battery heats up, the heat generated by the battery is transferred to the analog module, causing the temperature of the analog module to change , so as to simulate the heating process of the battery through the simulation module.

[0060] In step 202, the current flowing through the charging and discharging circuit of the battery is controlled according to the heating process of the battery.

[0061] In an exemplary embodiment of the present disclosure, by detecting the heating process of the battery simulated by the analog module, and then controlling the current of the charging and discharging...

Embodiment 3

[0064] Such as Figure 4 As shown, the embodiment of the present disclosure provides a battery temperature measurement and control method, the method includes:

[0065] In step 301, the heating process of the battery is simulated.

[0066] In an exemplary embodiment of the present disclosure, by disposing the thermistor in a preset area centered on the center of the battery, when the battery heats up, the heat generated by the battery is transferred to the thermistor, so that the thermistor The temperature changes, thereby simulating the heating process of the battery through the thermistor.

[0067] In step 302, the temperature of the battery is obtained during the process of simulating the heating process of the battery.

[0068] In the exemplary embodiment of the present disclosure, since the thermistor is arranged in a preset area centered on the center of the battery, the temperature of the thermistor is consistent with the temperature of the battery. When the battery g...

Abstract

The invention discloses a battery temperature measurement and control device, a battery temperature measurement and control method and a mobile terminal and belongs to the electronic equipment field. The battery temperature measurement and control device includes a simulation module and a control module; the simulation module is fixed on a battery and is located in a preset area with the center of a battery adopted as a center and is used for simulating the heat emitting process of the battery; the control module is electrically connected with the simulation module; and the control module is electrically connected with the charge / discharge circuit of the battery and is used for controlling current flowing through the charge / discharge circuit according to the heat emitting process of the battery. According to the battery temperature measurement and control device, the battery temperature measurement and control method and the mobile terminal of the invention, the simulation module is located in the preset area with the center of the battery adopted as the center so as to simulate the heat emitting process of the battery; and the control module controls the current flowing through the charge / discharge circuit according to the heat emitting process of the battery, and therefore, dangerous accidents such as explosions due to the excessively high temperature of the battery can be avoided.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a battery temperature measurement and control device, method and mobile terminal. Background technique [0002] The mobile terminal is powered by a rechargeable battery installed on one side of its back cover. Since the mobile terminal generates heat during use, the temperature of the battery will rise, and the battery will also generate heat during charging and discharging. In order to avoid battery charging and discharging Dangerous accidents such as explosions may occur due to excessive battery temperature during the process. When the battery temperature is too high, it is necessary to control the charging and discharging current of the battery to avoid continuous heating of the battery. [0003] However, the prior art still lacks a device that can control the charging and discharging current of the battery according to the temperature of the battery. Contents of the inve...
