S11, in terminal charge process, Real-time Collection specifies the temperature value of sampled point;
S12, as temperature value as described in detecting exceedes threshold value, then carry out cooling process, then continue charging.
The method of the present embodiment can prevent charging excess temperature from stopping, and reaches efficient charging, effectively control terminal heating and strengthens the effect of Consumer's Experience.
Fig. 2 is the flow chart of the method for the charging of the present invention one application example, and as shown in Figure 2, the method for this example comprises:
Step S21, when user inserts USB or charger or other charging devices, detects to insert and interrupts;
Step S22, has no progeny in detecting, starts to perform charging behavior, first judges whether battery electric quantity is full of, and as being full of, then performs step S27, otherwise performs step S23;
Step S23, starts the temperature value collecting each sampled point;
Step S24, according to these temperature values, carries out cooling process, as limited charging current accordingly and limiting by the CPU(Central Processing Unit of the master chip of charging terminal, central processing unit) frequency, then continue charging process, i.e. step S25;
Step S25, is charged state machine, constantly can reads temperature value, if temperature exceedes some boundary can perform step S24.If charger is removed, i.e. step S28, then perform step S29, stops charging.If battery has been filled, i.e. step S26, then performed step S27, charging complete;
Step S26, when battery is filled, is full of interruption and is triggered;
Step S27, charging complete, reset relevant setting;
Step S28, when user removes charging device, produces and interrupts;
Step S29, stops charging, and reset relevant setting.
Fig. 3 is the schematic diagram of the charging device of the embodiment of the present invention, and as shown in Figure 3, the charging device of the present embodiment comprises:
