Fig. 2 is the system schematic for meeting charging system in the preferred embodiment of the utility model one.
Reference：
10- charging systems, 11- charging equipments, 12- mobile terminals, 111- charging chips, 112- control chips.
Specific embodiment
Advantage of the present utility model is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Refering to Fig. 2, to meet the system schematic of charging system 10 in the preferred embodiment of the utility model one.Charging system
10 are mainly made up of charging equipment 11 and mobile terminal 12, and charging equipment 11 receives electric energy or the part electric energy that is stored with from power network,
When mobile terminal 12 is connected with charging equipment 11, charging equipment 11 provides electric energy to mobile terminal 12.In the charging equipment 11,
It is additionally provided with charging chip 111 and control chip 112, equipment of the charging chip 111 for conversion civil power to an electric current is filled, control chip
112 are connected with charging chip 111, the discharge mode for controlling charging chip 111, such as output current, the size of output voltage.
Specifically, charging time threshold is preset with control chip 112, as the comparison other in charging interval, in charging equipment 11 pairs
When mobile terminal 12 proceeds by charging, control chip 112 can be recorded by devices such as timers to the charging interval, and will
Charging interval after record is compared with charging time threshold.It is long between when charging, and more than default charging interval threshold
During value, control chip 112 can determine whether that, to have been carried out prolonged charging, mobile terminal 12 has had enough electric energy, so that
Without being charged again, thus, control chip 112 sends the instruction for stopping charging to charging chip 111.Charging chip 111 will
Stop charging mobile terminal 12 according to the instruction.By above-mentioned configuration, user can voluntarily grasp the time of charging, at night
It sleep soundly when cannot disconnect charging equipment 11 manually, charging relation can be automatically disconnected by the setting of control chip 112, extends electricity
The life-span in pond, and save electric energy.For example, the default charging interval is set to 2 hours, then self-charging started to after 2 hours, will be right
Mobile terminal 12 persistently charges, after 2 hours are reached, even if charging equipment 11 is still connected with mobile terminal 12, between the two
Charging relation no longer maintain.
It is understood that after charging chip 111 is according to charging instruction complete charge is stopped, control chip 112 will
It is not sent further on instruction of restarting to charging chip 111.That is, in the case where charging equipment 11 and mobile terminal 12 is not turned off, filling
Electric equipment 11 will not carry out filling energy to mobile terminal 12 again.Therefore, it is not influence user to operate, is set in control chip 112
There is clearing unit, when charging equipment 11 and mobile terminal 12 disconnect, the normal work of charging chip 111 will be recovered, until next
The connection of secondary charging equipment 11 and mobile terminal 12, and with above-mentioned configuration mobile terminal 12 is charged again.
The popularization all the more of quick charge is tackled, in order to by the time match of charging interval and quick charge, control chip 112
Interior also predeterminable have charging voltage threshold value.When charging equipment 11 is initially connected with mobile terminal 12, charging equipment 11 is to mobile whole
Hold 12 low-voltages to charge, and gradually step up charging voltage and charging current, until enter into fill state soon, now charging voltage compared with
Height, then according to the charging voltage threshold value set in control chip 112, when charging voltage is more than or equal to charging voltage threshold value
When, can just start above-mentioned configuration, control chip 112 starts timing, for being compared with charging time threshold.
Similarly, stood head and shoulders above others if meeting and filling effect soon, when just mobile terminal 12 is full of within the default charging interval, control
Power-off time threshold value will be also set in chip 112, when power-off time threshold value is reached in the charging interval of record, filled automatically cutting off
Electricity, no matter now mobile terminal 12 whether be full of, it is long to avoid charging repeatedly or continue the charging interval.
In mobile terminal 12, a configuration interface and dispensing unit can be also provided with, preferably can be application program, it is convenient
User operates.User can voluntarily set above-mentioned charging interval threshold, charging voltage threshold value by the operation to configuring interface
Or power-off time threshold value, dispensing unit then by user set above-mentioned parameter send to control chip 112, control chip
112 preferentially will be defined as configuration using above-mentioned parameter.
No matter above-mentioned one or more threshold value parallel form is used in embodiment, finally all can be in single charge mistake
Stop charging of the charging equipment 11 to mobile terminal 12 in journey, to reach above-mentioned technique effect.
It should be noted that embodiment of the present utility model has a preferably implementation, and not the utility model appointed
The limitation of what form, any one skilled in the art changes or is modified to possibly also with the technology contents of the disclosure above
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to technical spirit pair of the present utility model
Any modification or equivalent variations and modification that above example is made, still fall within the range of technical solutions of the utility model.
