Technical field
The present invention relates to electronic circuit technology field, particularly relate to a kind of portable power source.
Background technology
Portable power source is a kind of portable charger collecting power supply and charging and one, it can charge or standby power whenever and wherever possible for various electronic equipment, generally that lithium battery or dry cell are as charge storage unit, be different from the battery of interiors of products, generally be configured with multiple power sources adapter, the feature such as usually have that Large Copacity, multipurpose, volume are little, the life-span is long and safe and reliable, at any time for the multiple digital products such as mobile phone are powered or the functional product of standby charging.
But existing portable power source stores electricity, if improper in the process of charging to electronic equipment, will cause damage to electronic product.
Therefore, there is portable power source in prior art and unsafe technical problem.
Summary of the invention
The embodiment of the present invention is by providing a kind of portable power source, solve in prior art and there is portable power source when charging easily to by the hurtful technical problem of electronic equipment of charging, and then achieve portable power source can ensure electronic product fail safe when charging, reduce the technique effect of the infringement to electronic product.
The invention provides a kind of portable power source, comprise: charging circuit, battery, voltage control circuit and protective circuit, wherein, charging circuit is battery charging, and battery is that voltage control circuit is powered, and whether the electric discharge that protective circuit detects battery is abnormal, when detecting abnormal, forbidding that battery discharges, when not detecting abnormal, allowing battery discharge; Voltage control circuit control voltage exports situation.
Further, protective circuit comprises testing circuit and control circuit, and testing circuit detects whether short circuit or the overload of battery; when battery short circuit or overload being detected; being controlled to forbid battery discharge by control circuit, when detecting that battery is normal, allowing battery discharge by control circuit.
Further, voltage control circuit, when detecting that the output current of battery is less than pre-set current value, controls current magnitude of voltage to raise; When detecting that the output current of battery is not less than pre-set current value, keep current output voltage values.
The one or more technical schemes provided in the embodiment of the present invention, at least have following technique effect or advantage:
Owing to have employed, charging circuit, battery and voltage control circuit and protective circuit are set in portable power source, wherein, charging circuit is battery charging, battery is that voltage control circuit is powered, whether the electric discharge that protective circuit detects battery is abnormal, when detecting abnormal, forbids that battery discharges, when not detecting abnormal, allow battery discharge; Voltage control circuit control voltage exports situation, solve in prior art and there is portable power source when charging easily to by the hurtful technical problem of electronic equipment of charging, and then achieve portable power source can ensure electronic product fail safe when charging, reduce the technique effect of the infringement to electronic product.
Accompanying drawing explanation
Fig. 1 is the module diagram of portable power source in the embodiment of the present invention.
Embodiment
The embodiment of the present invention is by providing a kind of portable power source, solve in prior art and there is portable power source when charging easily to by the hurtful technical problem of electronic equipment of charging, and then achieve portable power source can ensure electronic product fail safe when charging, reduce the technique effect of the infringement to electronic product.
In order to solve above-mentioned portable power source charge time easily to by the hurtful technical problem of electronic equipment of charging, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
The invention provides a kind of portable power source, as shown in Figure 1, comprising: charging circuit 101, battery 102, voltage control circuit 103 and protective circuit 104, wherein, charging circuit 101 charges for battery 102, battery 102 is powered for voltage control circuit 103, whether the electric discharge that protective circuit 104 detects battery 102 is abnormal, when detecting abnormal, forbids that battery 102 discharges, when not detecting abnormal, battery 102 is allowed to discharge; Voltage control circuit 103 control voltage exports situation.
In a particular embodiment, protective circuit 104 comprises testing circuit and control circuit, and testing circuit detects battery 102 whether short circuit or overload, when battery 102 short circuit or overload being detected, is controlled to forbid battery discharge by control circuit; When detecting that battery is normal, battery 102 is allowed to discharge by control circuit.Like this, effectively prevent portable power source to the infringement being connected to the electronic equipment that portable power source charges.
Voltage control circuit 103 can export situation control voltage according to voltage, and particularly, voltage control circuit, when detecting that the output voltage of battery is less than pre-set current value, controls current magnitude of voltage to raise; And when detecting that the output current of battery is not less than pre-set current value, keep current output voltage values.Thus further by controlling the situation of output voltage, protect the electronic equipment be connected with portable power source to suffer damage.
Although describe the preferred embodiments of the present invention, those skilled in the art once obtain the basic creative concept of cicada, then can make other change and amendment to these embodiments.So claims are intended to be interpreted as comprising preferred embodiment and falling into all changes and the amendment of the scope of the invention.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
