On, the function of increase temperature adjustment protection is highly desirable when being.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of simple in construction, design is closed
Reason, a kind of portable power source with temp regulating function easy to use.
To achieve the above object, the technical solution adopted in the utility model is：A kind of movement with temp regulating function
Power supply, it includes housing (1), charging inlet (4) and installed in housing (1) internal circuit board and lithium battery (2)；It is described
MCU controllers (3) are installed, the MCU controllers (3) are electric with charging inlet (4), charge pulse-width modulation respectively on circuit board
Road (5), battery protecting circuit (6), NTC themistor (8) and the lithium battery (2) electrical connection, the lithium battery (2) with
Battery protecting circuit (6) electrical connection, the battery protecting circuit (6) electrically connect with the charge pulse-width modulation circuit (5),
The charge pulse-width modulation circuit (5) electrically connects with the charging inlet (4), and the MCU controllers (3) also show with LED state
Showing device (7) electrically connects.
Preferably, the NTC themistor is arranged on the lithium battery side.
After said structure, the utility model has the beneficial effect that：Present apparatus MCU is provided with NEC (temperature inductor) company
Adapter pin；NTC is close to lithium battery, super when due to high current factor, causing battery core temperature to rise during charge or discharge
When crossing 50 degree, MCU control charging circuits, input current is reduced, when battery core temperature is more than 60 degree, directly shut-off input stopping is filled
Electricity, reach the purpose of protection.

Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
Referring to shown in Fig. 1-Fig. 4, the technical scheme that present embodiment uses is：
Embodiment 1：
A kind of portable power source with temp regulating function, it includes housing 1, charging inlet 4 and in housing 1
The circuit board and lithium battery 2 in portion；MCU controllers 3 are installed on the circuit board, the MCU controllers 3 respectively with charging
Mouth 4, charge pulse-width modulation circuit 5, battery protecting circuit 6, NTC thermal resistors 8 and the lithium battery 2 electrically connect, the lithium
Battery 2 electrically connects with the battery protecting circuit 6, and the battery protecting circuit 6 is electrically connected with the charge pulse-width modulation circuit 5
Connect, the charge pulse-width modulation circuit 5 electrically connects with the charging inlet 4, and the NTC themistor is arranged on lithium electricity
Pond side.
This programme principle is as follows：NTC (thermistor) connection pin during MCU14 pin；NTC is close to lithium battery, is filling
In electricity or discharge process, when due to high current factor, causing battery core temperature to be increased beyond 50 degree, MCU control charging circuits,
Input current is reduced, when battery core temperature is more than 60 degree, directly shut-off input stops charging, reaches the purpose of protection.
It is described above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
The other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, it all should cover among right of the present utility model.
