The negative pole ground connection of pond group 1, the voltage transformation module 2 is connected with the positive pole and logical time delay unit 3 of load incoming end respectively, institute
The one end for stating current detecting unit 7 is connected with logical time delay unit 3, and the other end and the load of the current detecting unit 7 are accessed
The negative pole connection at end, one end of the divider resistance 6 is connected with the negative pole of load incoming end, the other end of the divider resistance 6
Ground connection, during work, detection 9 current values of load of the current detecting unit 7, and logical time delay unit 3 is returned to, logical time delay list
Unit 3 compares the switch of control voltage converter unit 2 according to the threshold values of current value and setting, when current value is less than threshold values, logic
Output in the short time of 3 control voltage converter unit of delay unit 2, so as to realize that portable power source automatic shutdown is controlled.
But, because the limitation of cost, while the influence in order to reduce current detector efficiency, detector impedance very little
In the case of, portable power source is limited to the accuracy of detection of low current, is commonly defined as referring to threshold values as one between 50-100mA.
But, many products, particularly small Bluetooth equipment, its normal charging current are also almost just this scope, Er Qie
The last low current constant voltage charging phase for charging, its electric current only has 2-3mA, so as still with this traditional automatic shutdown side
Method, these equipment cannot be by normal fully charged.It is to increase delay time, such as 2 hours or more to compare interim solution
Automatic shutdown delay time long, but so can equally bring other problem：Portable power source holds during carrying with
Easy false touch triggers start, and portable power source keeps starting shooting for a long time in the case of without connection equipment can equally cause meaningless energy
Amount consumption；If when accessing, portable power source is already powered on other low current charge equipment because of false touch, then as equipment connects
Entering rear delay time not enough causes the situation generation for charging discontented.
The content of the invention
The present invention in view of the existing deficiencies of the prior art, there is provided a kind of aptitude chargeable circuit and apply the aptitude chargeable circuit

The present invention compared with prior art, with advantages below and advantage, specifically, by traditional portable power source
Increase voltage detection unit, unilateral diode and switch in charging circuit to realize being the low current equipment fully charged rear short time
The interior function of closing portable power source；Because voltage detection unit, unilateral diode and switch are inexpensive, this movement is so made
The cost increase extremely pettiness of power supply, is basically increased without cost, is so conducive to this product large-scale popularization；Pass through
Current detecting unit and the current value and magnitude of voltage of voltage detection unit detection load, if current value and magnitude of voltage are zero,
Output in portable power source not access device, logical time delay unit control voltage converter unit short time is represented, thus can be real
Now the automatic shutdown in the portable power source short time when equipment is not accessed, reduces unnecessary energy loss, extension portable power source
Use duration.
