Embodiment
Below technical solution of the present invention is described in detail, but protection scope of the present invention is not limited to described embodiment.
embodiment 1:as shown in Figure 1, lead-acid battery charger rapid and handy formula tester of the present invention, comprising: battery, electric capacity pump booster circuit, diode, analog to digital converter, single-chip microcomputer, LED digital display screen, cement resistor load and field effect transistor;
The negative pole of battery is connected with charger negative pole and ground connection, and the positive pole of battery is connected with the input end of electric capacity pump booster circuit and the power supply port of single-chip microcomputer, powers to electric capacity pump booster circuit and single-chip microcomputer; The output terminal of electric capacity pump booster circuit is connected with the negative electrode of diode, and the anode of diode has the positive pole of the charger of safety function to be connected with outside; The input end of analog to digital converter is connected with the negative electrode of diode and the output terminal of electric capacity pump booster circuit simultaneously, and the output terminal of analog to digital converter is connected with the digital input port of single-chip microcomputer; One end of cement resistor load is connected with diode cathode, and the other end is connected with the drain electrode of field effect transistor, and the source electrode of field effect transistor is connected with the negative pole of charger and ground connection, and the grid of field effect transistor is connected with the digital output of single-chip microcomputer; The digital output of single-chip microcomputer is connected with display screen, and the earthing pole of single-chip microcomputer is connected with charger negative pole and ground connection.
Specific works flow process: battery is powered to electric capacity pump booster circuit, produce 24V-36V trigger voltage, trigger voltage inputs to the negative electrode of the diode being connected to charger positive pole, had outside the charger of safety function to activate to open, now by the signal of analog to digital conversion circuit, single-chip microcomputer learns that power supply is opened, immediately field effect transistor was opened for 0.1 second, now cement resistor load joins in charger loop.Owing to there being diode-isolated, contrary the inserting without safety charger of polarity of voltage, tester can not power on, self-protection.Before field effect transistor opened for 0.1 second, external charger is inserted and is the floating charge state of green light after activating, and field effect transistor is opened in 0.1 second, be transformed into the constant-current charge state of red light, field effect transistor is transformed into green light phase from red light phase after opening for 0.1 second, completes a circulation of test.Follow badly at this, single-chip microcomputer is recorded by the voltage status of analog to digital conversion circuit by charger, shows after completing calculating on LED digital display screen.
As mentioned above, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
