MIC) the special sound of collection.
S202, judgement meet quick charge condition.
When default operational order is received, terminal device judges to meet quick charge condition.
S203, judgement are unsatisfactory for quick charge condition.
When default operational order is not received by, terminal device judges to be unsatisfactory for quick charge condition.
So as to user can conveniently be improved to improve the speed that externally charges by operational order to output current
Degree.
In further embodiments, quick charge condition can be set by presetting battery power threshold, now,
Terminal device judges whether to meet the idiographic flow of quick charge condition as shown in figure 4, comprising the following steps：
Whether S301, acquisition battery electric quantity, judge battery electric quantity more than or equal to threshold value.When battery electric quantity is more than or equal to
During threshold value, step S302 is performed；When battery electric quantity is less than threshold value, step S303 is performed.
Specifically, when terminal device carries out OTG connections as main equipment, terminal device detects the current electricity of the machine immediately
Pond electricity, or directly read the current battery electric quantity of the machine from battery management application.Compare current battery electric quantity and threshold value
Size, judge battery electric quantity whether more than or equal to threshold value.

S302, judgement meet quick charge condition.
When battery electric quantity is more than or equal to threshold value, terminal device judges to meet quick charge condition.
S303, judgement are unsatisfactory for quick charge condition.
When battery electric quantity is less than threshold value, terminal device judges to be unsatisfactory for quick charge condition.
So as to when detecting battery electric quantity and being higher, then improve output current to accelerate external charging rate；When battery electricity
When measuring relatively low, then externally charged with normal output current, or output current can also be limited, be reduced to default water
It is flat, to protect the electricity of terminal device, extend cruising time.
In further embodiments, quick charge condition can be set by presetting the temperature threshold of slave unit,
Now, terminal device judges whether to meet quick charge condition in the following manner：The temperature of slave unit is obtained, slave unit is judged
Temperature whether be less than or equal to threshold value；When the temperature of slave unit is less than or equal to threshold value, judgement meets quick charge condition；
When the temperature of slave unit is more than threshold value, judgement is unsatisfactory for quick charge condition.
Terminal device can according to agreement or instruction control slave unit in real time or timing detection slave unit temperature, work as temperature
When degree is more than or equal to threshold value, terminal device then improves output current to accelerate the charging rate to slave unit；When temperature is more than
During threshold value, then slave unit is charged with normal output current, or output current can also be limited, be reduced to default water
It is flat, to prevent slave unit from overheating, protect slave unit.
Similarly, terminal device can also detect the temperature of the machine (i.e. main equipment), judge the machine temperature whether be less than or
Equal to threshold value；When the temperature of the machine is less than or equal to threshold value, judgement meets quick charge condition；When the temperature of the machine is more than threshold
During value, judgement is unsatisfactory for quick charge condition.
It will be understood by those skilled in the art that in addition to using above method setting quick charge condition, can also use
Other similar approach.Will not enumerate herein and repeat.
