Tester circuit is powered by 5v power supply, and during use, the positive pole a0 of charger charging plug is connected to a end, through r10 and
The ground connection g0 of potentiometer vr to g end, g end and charger practices level.Voltmeter, inspection are installed between a the and b connection terminal of testing circuit
Ammeter is installed between e the and f connection terminal of slowdown monitoring circuit.
Charger tester circuit use when, a, b, g terminal of tester circuit, the charging plug with charger respectively
Positive pole a0, charger charging plug negative pole b0, charger ground connection g0 terminal connect.No. 1 terminal of u connects through r3, r4 and charger
Ground g0 connects, and No. 2 terminals of u are connected to the negative pole b0 of charger charging plug through r7.Resistance r9 and light emitting diode vr is constituted
The indicating circuit of tester.
Embodiment 1, the detection of charger constant current value:
Adjusting vr makes the electric current of r0 increase, and when the electric current of r0 increases to the constant current value of charger, the voltage on r0 will touch
Send out the constant-current control circuit action in charger, output voltage is reduced by charger, so that the electric current of r10 and vr reduces, vr
The voltage of sliding end is limited rising, reaches balance.Continue to adjust vr toward same direction, the output voltage of charger can only be made
Reduce further, less, the current value at this moment reading from ammeter is exactly the constant current value of charger to the curent change on r0.
Embodiment 2, the detection of charger constant voltage value:
Adjust vr by the opposite direction that embodiment 1 is adjusted, because charger is still in current constant control state, the curent change of r0 is not
Greatly, the output voltage of charger will gradually rise, and when continuation regulation vr can not make charger voltage continue to raise, enter into perseverance
Pressure state of a control, charger output voltage keeps constant.Because charger output voltage is constant, the current constant of r10, vr, this
Shi Jixu adjusts vr, and the voltage of vr sliding end will reduce, so that the electric current reduction on r0, at this time the reading on voltmeter is just
It is charger constant voltage value.
Embodiment 3, the detection of charger trickle charge voltage
Continue to adjust direction regulation vr by embodiment 2, the voltage of vr sliding end continues to reduce, and the electric current on r0 subtracts further
Little, and the output voltage of charger is constant.When the electric current on r0 reduces, because charger output voltage declines suddenly, r10, vr
Electric current also reduce suddenly, this makes the voltage of vr sliding end reduce suddenly, leads to electric current on r0 to decline suddenly a lot.Permissible
Obtain the value of this parameter of charger, after current break, the reading of voltmeter is exactly the output electricity in charger trickle charge stage
Pressure value.Above whole process just likes a complete charging process.
Embodiment described above is only embodiment of the present utility model to be described, not to the utility model
Spirit and scope be defined.On the premise of without departing from the utility model design concept, this area ordinary person is to this reality
The various modifications made with new technical scheme and improvement, all should drop into protection domain of the present utility model, and this practicality is new
The scope of type is limited by claims rather than described above.
