[0027] See Figure 1-2 , which shows a structural diagram of the charging circuit provided by the first embodiment of the present invention, the charging circuit may include:
[0028] The detection module 101 is used to detect the temperature of the battery.
[0029] Here, the detection module 101 detects the temperature of the battery, which provides data support for the subsequent conversion of the charging mode according to the temperature of the battery.
[0030] The first charging module 102 is configured to charge the battery 104 with a first current when the temperature of the battery is greater than or equal to a preset value.
[0031] Here, when the temperature of the battery is greater than or equal to a preset value, the first charging module 102 uses the first current to charge the battery 104 to ensure the charging efficiency of the battery 104, wherein the preset value is required by normal charging Threshold value of battery temperature.
