Step S10, when terminal is charged with predetermined current, whether sense terminals is current is hand holding state; If so, then perform step S20, otherwise perform step S30;
Step S20, when the temperature that terminal is current is greater than the maximum of the first preset range, reduces the charging current of described terminal;
Step S30, when the temperature that terminal is current is greater than the maximum of the second preset range, reduces the charging current of described terminal; The maximum of described first preset range is less than the maximum of the second preset range.
The terminal charging method that the embodiment of the present invention provides is mainly used in portable mobile termianl, for controlling the charging modes of terminal.This terminal can be mobile phone, flat board etc.Detailed description is made for mobile phone in following examples.Particularly, inductor can be set at the periphery of mobile phone current whether for grip state with detection of handset, such as this inductor can be pressure-sensitive device, such as piezo-resistance, pressure-sensitive capacitance etc. can also be adopted, the mode of concrete detection can be arranged according to actual needs, does not do limiting further at this.The size of above-mentioned predetermined current, the first preset range and the second preset range can be arranged according to actual needs, does not also do limiting further at this.The current temperature of above-mentioned terminal can be detected by preset temperature transducer, particularly, the position that this temperature sensor is arranged can be arranged according to actual needs, and heating position that such as can be main when terminal charge, as arranged near battery of mobile phone.
Be mobile phone below with terminal, predetermined current is 2A, the first values is 35 DEG C ~ 40 DEG C, the second preset range is 40 DEG C ~ 45 DEG C and makes detailed description for example.Now, the maximum of above-mentioned first preset range is 40 DEG C, and the maximum of the second preset range is 45 DEG C.When after the charger that mobile phone connects, mobile phone will enter charge mode, and the electric current with 2A charges to battery of mobile phone by the charging control circuit in mobile phone, and the temperature sensor that Real-time Obtaining is preset detects the temperature T of mobile phone.Now the pressure-sensitive device arranged according to periphery is detected determine terminal current whether be grip state, under mobile phone is grip state, when temperature T is greater than 40 DEG C, by the charging current of adjustment to battery of mobile phone, charge with the electric current lower than 2A; Under mobile phone is non-grip state, when temperature T is greater than 45 DEG C, by the charging current of adjustment to battery of mobile phone, charge with the electric current lower than 2A.
