Abstract
The utility model relates to a with the conversion equipment that automatic control charger charges to the battery in the electrical apparatus control field. The system is composed of an input interface 1, a charging signal sensor 2, a comparator 3, a voltage-controlled oscillator 4, a channel control distributor 5, a channel relay 6 and a battery socket group 7. The charging time and the charging saturation depth are automatically controlled by monitoring the charging current or the charging voltage of the battery in the charging process. So as to avoid unnecessary loss or adverse consequences caused by the non-uniformity of the human control time. Meanwhile, a plurality of batteries can be controlled to be charged in turn at one time, and automatic switching under an unmanned state is realized.
Description
The utility model is to control the conversion equipment of charger to battery charge automatically about being used in the electrical equipment control field.
Charger in the prior art is to lean on people's memory time, controls the charging degree of saturation of battery, and changes battery by manually getting, to reach the charging to the polylith battery.This charger uses both inconvenient, time-consuming again.Particularly, need for a long time several hrs at least, tens hours and even twenties hours at most to the charging of high capacity cell.If charging interval control is inaccurate, will bring adverse consequences.Charging interval is long, can reduce battery useful life so that damage battery, and the charging interval is too short, charges not full and influences the result of use of battery.
The purpose of this utility model is for a kind of automatic control equipment of charging process is provided, promptly have automatic control charging interval and charging saturation depth, automatically conversion battery the charging order, cut off the charging switching controller of function such as charge circuit automatically, to replace artificial supervision, artificial memory's charging interval and manually to get worried work such as changing battery, simultaneously, the adverse consequences to avoid bringing owing to the charging interval departure.
The utility model as shown in Figure 1, be made of input interface 1, charging signals transducer 2, comparator 3, voltage controlled oscillator 4, passage control dispenser 5, passage relay 6 and battery socket group 7, wherein charging signals transducer 2 is that charging current variation or charging voltage are changed the functional circuit that conversion is enlarged into the signal of telecommunication.Comparator 3 is the voltage values of giving that provide setting by potentiometer, with this reference as the charging saturation depth.Charging signals transducer 2 is defeated by comparator 3 with the variation in the charging circuit, the reference voltage value of giving that sets with comparator 3 compares, when the signal of this variation reaches predetermined value, comparator 3 output useful signals, it is the pulse of T that this useful signal makes the 4 generation cycles of voltage controlled oscillator, the running of control channel control dispenser 5.T cycle of oscillation that voltage controlled oscillator 4 is produced should change stabilization time greater than passage.Passage control dispenser 5 is the control dispensers that produce the passage switching signal, realizes that with control channel relay 6 break-make of passage is switched.Battery socket group 7 is by passage relay 6 control, realizes the functions such as automatic control flows electricity, automatic sequential conversion to battery.
An embodiment of the present utility model is made of casing, input and output plug-in unit, function selecting control switch, state display lamp and dial gauge and control circuit system.The input and output plug-in unit is the interface that is complementary with charger and rechargeable battery.The function selecting control switch is provided with mains switch and button is executed in saturation depth calibration adjustment.State display lamp is in order to show the operating state of charging, and dial gauge is in order to show the degree of saturation of charging.Control circuit system as shown in Figure 2, the charging signals transducer is a current sensor, by little resistance resistance R x and amplifier A
1Constitute.Comparator adopts Schmidt circuit.Be provided with follower A in the circuit
2, according to amplifier A
1Output signal drives the indication gauge outfit, and simulation shows energy content of battery change procedure.Voltage controlled oscillator is a voltage-controlled square wave generation circuit, selects LM324 amplifier A for use
4, electric capacity, resistance and diode constitute, its frequency of oscillation is mainly by capacitor C
1And resistance R
7Decision, cycle of oscillation, the selection of T should be changed stabilization time greater than passage.The passage control dispenser is by count splitter υ
1With cycle controller υ
2Constitute, select for use two CMOS4017 to constitute.Cycle controller υ
2Can make the running of channel controller reciprocation cycle, to avoid the omission in the single cycle.Decide cycle-index end, loop control distributor υ when giving
2The output level"1" is with CIOCK(INKIBT) be set to illegal state, each path control end " 0 "～" 7 " becomes the zero level disarmed state.Count splitter υ
1Output " 0 "～" 7 ", the switching of each channel selector relay of driver connected control.Channel switch is selected the enough relays of contact capacity for use, and it is the DC power supply of 12V that power supply is selected voltage for use.
The utility model has been realized in the battery charging process, automatically control charging interval and charging saturation depth, and can be to the conversion charging according to the order of sequence automatically of polylith battery, after charging is all over, can cut off charge circuit automatically, replace artificial supervision, artificial memory's charging interval and manually got tired lock work such as changing battery, the unnecessary loss of also having avoided human error to cause.
