步骤S7，根据第一充电电流值、温度和第二预设规则运算出第二充电电流值，第二充电电流值小于第一充电电流值；根据第一充电电压值和第二预设规则运算出第二充电电压值，执行步骤S9。Step S7, calculate the second charging current value according to the first charging current value, temperature and the second preset rule, the second charging current value is smaller than the first charging current value; calculate according to the first charging voltage value and the second preset rule If the second charging voltage value is obtained, step S9 is executed.
步骤S8，根据第一充电电流值、温度和第二预设规则运算出第二充电电流值，第二充电电流值大于第一充电电流值；根据第一充电电压值和第二预设规则运算出第二充电电压值，执行步骤S9。Step S8, calculate the second charging current value according to the first charging current value, temperature and the second preset rule, the second charging current value is greater than the first charging current value; calculate according to the first charging voltage value and the second preset rule If the second charging voltage value is obtained, step S9 is executed.
步骤S9，将第二充电电流值和第二充电电压值通过数据线300传输至适配器200，以供适配器200根据第二充电电流值和第二充电电压值输出第二充电电压和第二充电电流。Step S9, transmit the second charging current value and the second charging voltage value to the adapter 200 through the data line 300, so that the adapter 200 can output the second charging voltage and the second charging current according to the second charging current value and the second charging voltage value .
步骤S10，当前电压值达到预设饱和电压值时，停止为移动终端的电池充电。Step S10, when the current voltage value reaches the preset saturation voltage value, stop charging the battery of the mobile terminal.
本实施例中先将温度值与上极限值进行比较，再将温度值与下极限值进行比较。对于温度值先与下极限值进行比较，再将温度值与上极限值进行比较的技术方案也在本实用新型的保护范围以内。In this embodiment, the temperature value is first compared with the upper limit value, and then the temperature value is compared with the lower limit value. The technical solution of comparing the temperature value with the lower limit value first, and then comparing the temperature value with the upper limit value is also within the protection scope of the present invention.
