Flow chart shown in Figure 1, the present embodiment provide a kind of charge control method, are terminal for passing through intelligent socket
Equipment charge, comprises the steps：
The charging voltage of step S11, detection terminal equipment；
Charged for terminal device by intelligent socket, according to the difference of the magnitude of voltage of the terminal device for detecting, take phase
The charging modes answered, the method using charging modes are selected according to the magnitude of voltage of terminal device can expand the suitable of charging equipment
With property, e.g., terminal device is panel computer or smart mobile phone, although the amount of capacity of the two battery is variant, but the two
The charging modes taken in identical voltage range are identical, therefore, the voltage of detection terminal equipment can expand charge control side
The applicability of method.
Step S13, when the cell voltage of terminal device reaches first voltage value, intelligent socket provides constant charging electricity
Flow and charge for terminal device；
First voltage value, here are the critical value that the battery of terminal device can just support terminal device normal boot-strap, existing
There are terminal device (such as smart mobile phone or panel computer), generally 3.0-3.2V (such as 3.0V, 3.1V or 3.2V), in terminal device
