The operation principle of the present invention is that：Isolating transformer is depressured about 220V AC voltage, is about down to exchange 18V
To 20V, direct current is then rectified by rectifier bridge, the voltage after rectification becomes smooth DC voltage after filter capacitor,
Its value is about 24V~26V, needs to be followed by the pipe that insures in rectifier bridge, is can effectively prevent in this way because circuit is burnt in short circuit, rectification
Voltage source of the DC voltage of filter output as whole system, first is that constant pressure and constant streaming charging circuit offer power supply is provided, two
It is to provide power supply to system power supply circuit, what constant pressure and constant streaming charging circuit was mainly made of voltage-controlled type chip TL494
Buck circuit is reequiped on original buck type topological circuit, and foring can be filled with what constant pressure, constant current mode arbitrarily switched
Circuit.
After the second capacitor C2 in constant voltage constant current charging circuit and connects and be made of first resistor R1 and the 8th resistance R8
Voltage sample feedback network, first resistor R1 are that slide rheostat its resistance value is adjustable, can adjust sampling by adjusting the resistance
The size of voltage value, the voltage sampled from voltage sample node Sample_Voltage are accessed by the second relay K2
1 pin of TL494,1 pin of TL494 are the noninverting inputs of its builtin voltage comparator, pass through the DA of MK60 control system
Channel exports corresponding voltage and just can control the corresponding voltage value of charging circuit output to 2 pins of TL494, due to the second relay
2 pins and 5 pins of device K2 are in connection status when not switching, so charging circuit works in constant pressure mould when K2 does not switch
At this moment formula only need to be to make by the output voltage of the accurate real-time control charging circuit of MK60 control system energy, the 9th resistance R9
It is used for current sampling resistor, it is necessary to improve the precision of current sample and reducing the power loss in sampling process
Using constantan wire resistance and resistance value it is smaller be 0.5 Europe or so, after output port P2 connects load, have electric current flow through R9 to
Pressure drop is generated on Sample_Current network node, since Sample_Current network node is the 4 pin phases with K2
Connection, so current sample feedback network cannot access TL494 when K2 does not switch, charging circuit works in constant current operation mould
Formula, when K2 switching when, current sample feedback network access TL494 will necessarily off voltage sampling feedback network and TL494 company
It connects, it is constant to can control charging circuit as long as the voltage value of the MK60 control system modification channel DA output while K2 switching in this way
Corresponding current value is exported, based on above-mentioned, the work of control charging circuit is by switching K2 come in fact in constant current or constant voltage mode
Now, how much the current value (voltage value) exported when constant current (constant pressure) mode is specially to be exported by the channel control system DA MK60
Voltage value determine, 16 DA output channels as built in MK60 single-chip microcontroller, thus can the very high voltage of output accuracy, thus
Realize accurately controlling for constant voltage output value or constant current output value, the switching of K2 is the control exported by means of MK60 control system I/O
What signal processed was completed, the base stage of the I/O access third transistor Q3 of control system, when I/O exports high level, Q3 is connected, Q3's
Collector has electric current to flow through so as to cause relay K2 switching, and 2 pins of K2 and 5 pins disconnect, 2 pins and 4 pins closure, when
Q3 ends when I/O exports low level, and the collector of Q3 does not have electric current to flow through to switch back into original state again so as to cause K2.
The switching of first relay K1 is also to be completed as K2 by means of MK60 single-chip microcontroller, and K1 accesses the master of charging circuit
Circuit, when circuit is without exception, 2 pins of K1 and 5 pins are connected circuit and are worked normally, if what circuit was flowed through due to suddenly-applied short circuit
Electric current increases us suddenly can be detected by the sensor of current sample network or external Hall sensor etc, be detected
Data can pass to MK60 control system and be handled, and control system issues control signal by I/0 and switches K1 disconnection electricity in time
Road, to realize the short-circuit protection to charging circuit, the UART communication module of setting is for PC control terminal and MK60 control system
Data communication is carried out, we can pass through UART bus transfer in the parameter that long-range PC control terminal inputs pulsed fast charge
Give MK60 control system, MK60 control system can be controlled according to received supplemental characteristic the K2 switching time of charging circuit with
And the voltage value that 2 pins of TL494 receive, in this way we can be arranged to real-time online or modify pulsed fast charge
Mode.
Our present invention charge to the battery of voltage rating 12V after material objectization, and used Bradycardia punching is quick
Charging modes are first with current value constant-current charge 30 seconds of 1.34A；Again with the current value constant-current charge of 0.33A 20 seconds；Finally with
Fixed voltage value carries out constant-voltage charge 60 seconds, and practice effect proves that it can effectively and rapidly complete the charging to battery, by
Constantly (it can reach 13V in full electricity situation, when electricity wretched insufficiency only has 11V left in variation in battery charged voltage value
It is right), so needing constantly to modify the voltage value of constant-voltage charge by single-chip microcontroller to optimize charging effect.
