The embodiment of the present invention provides a kind of charge control method, device and terminal, will be described in detail respectively below.
A kind of charge control method, the method can apply in terminal.The terminal includes the first battery and the second battery. The terminal can be the equipment such as smart mobile phone, panel computer.
It should be noted that two batteries during hereinafter the first battery, the second battery are served only for terminal make a distinction, Rather than refer in particular to.
As shown in figure 1, the charge control method, may comprise steps of:
S110, the first battery for terminal power when, persistently detect the voltage of first battery.
In practical application, the first battery can be connected with the power management chip in terminal, with by power management chip For terminal is powered.First battery for terminal power when, terminal can continue to detect the voltage of first battery.For example, terminal Can be with the voltage for detecting once first battery per second.
S120, when the voltage of first battery is less than the first predeterminated voltage, first battery stops being powered to the terminal.
Wherein, first predeterminated voltage can pre-set and store a magnitude of voltage in the terminal.First presets Voltage can be the low cutoff voltage that first battery can discharge.For example, the first predeterminated voltage can be 3.5V.
When terminal detect first battery voltage be less than first predeterminated voltage when, control first battery stop to The terminal is powered.
S130, the second battery is powered for the terminal, and for first battery charges.
Wherein, second battery can be with identical with the specification of first battery, it is also possible to different.Second battery can also It is connected with the power management chip in terminal.When the first battery stops being powered to the terminal, second battery passes through power supply pipe Reason chip is powered for the terminal.
Meanwhile, second battery is electrically connected with first battery.Second battery for the terminal power while, Ke Yiwei First battery charges.Second battery is powered for terminal, while for the application schematic diagram that the first battery charges is as shown in Figure 5.
With reference to Fig. 2, in certain embodiments, the second battery is powered for the terminal, and for first battery charging can To comprise the following steps:
