Description

The electric motor car energy-conservation socket that charges
Technical field:
The utility model relates to a kind of energy-conservation socket, can judge automatically that especially charger is finished battery charge after, change into the variation of low current charge, make the charging of its break-make charger, reach energy-conservation purpose.The general purpose type energy-saving socket belongs to electrical equipment (electronic product) field.
Background technology:
The energy-conservation socket that charges of electric motor car in the market, (patent No. 200520071071.7 is from cutting off the power supply the battery charge socket) arranged, and it mainly obtains current signal by sample resistance, realize controlling, and give circuit supply with two groups of resistance-capacitance depressurization circuit, this makes energy-conservation socket complexity, need big space to dispel the heat to circuit board, cost is higher.
Summary of the invention:
The purpose of this utility model is to provide a kind of trafficability characteristic good, and structure is terse, good energy-conserving effect, novel energy-conserving socket.This socket changes the power supply of realization cut-out charger by detecting the electric car charger charging current, reaches purpose of energy saving by eliminating the long-time power consumption of the little electric current of charger.
The purpose of this utility model is by realizing with technical scheme; A kind of electric motor car energy-conservation socket that charges, comprise that upper shell has socket (connecting charger uses), lower house has plug to have lead to connect current transformer output gang socket, current transformer two ends in addition connects optocoupler amplifier, output connects time-delay and drive integrated circult, time-delay is connected relay with drive integrated circult output, relay control upper shell socket.
The utility model operation principle: plug inserts civil power and gets, socket inserts electric car charger, charger connects battery of electric vehicle. and the current transformer T1 that inserts in plug and socket one line induces certain ac signal through VD6, the C3 rectification becomes dc signal, drive optocoupler amplifier IC1, the 12V direct current that resistance-capacitance depressurization is provided, through optocoupler amplifier IC1, the 12V direct current enters integrated circuit (IC) 2 trigger ends 6 and makes integrated circuit (IC) 2 output 12V dc powered relay J adhesives, makes electric car charger get electric work.
After battery of electric vehicle is full of electricity, charger changes into little electric current and carries out floating charge, at this moment current transformer T1 induces very little ac signal rectification is a dc signal through VD6.C3, but be not enough to drive the photoelectricity part of optocoupler amplifier IC1, the 12V direct current that resistance-capacitance depressurization is provided, can not pass through optocoupler amplifier IC, also just can not enter integrated circuit (IC) 2 trigger ends 6, make integrated circuit (IC) 2 start time-delay, delay time is by resistance R 5, R6, and capacitor C 4 is set, set 3--8 minute adjustable, delay time and arrived in 8 minutes, integrated circuit (IC) 2 outputs 8 are no longer exported the 12V direct current, and relay J is discharged, automatically cut off the civil power of socket, electric car charger is quit work.
The utility model electric motor car energy-conservation socket that charges: oneself power consumption is very little, has only 0.5W.Can detect electric current automatically and change, when electric car charger changes into little electric current floating charge, enter the time-delay timing automatically, after timing is arrived, cut off the electricity supply automatically, reach energy-conservation purpose.
Description of drawings:
Below in conjunction with accompanying drawing and enforcement the utility model is further specified.
Fig. 1 is energy-conservation socket functional-block diagram for the utility model electric motor car charges.
Fig. 2 is energy-conservation socket circuit schematic diagram for the utility model electric motor car charges.
Embodiment:
Shown in Figure 2, the utility model electric motor car energy-conservation socket that charges, current detecting is by current transformer, and diode, electric capacity are formed the sensor current signal that obtains and are inserted optocoupler amplifier.After charger is finished battery charge, sensor current signal can not make optocoupler amplifier work, make the optocoupler amplifier output valve become low level (below the 1V) from high level (more than the 6V) thus make the time-delay and the trigger end 6 of drive integrated circult be not enough to trigger collecting circuit, integrated circuit enters the delayed startup state, and delay time is set by resistance R 5.R6. capacitor C 4.This example was established 8 minutes, and after delay time was finished, drive circuit release relay J finished automatic cut-out power consumption equipment.
The above-mentioned integrated circuit (IC) 2 that is used as time-delay and drive circuit is selected CD4541BE or MC14541 for use.Polypropylene capactive C1 selects 474J/630V for use.Current transformer T1 selects EI14 for use.Optocoupler amplifier IC1 selects PC817 for use.Relay is selected JQC-12V for use.Diode VD1-4 selects IN4007 for use.VD6-7 selects IN4148 for use.VD5 selects the 12V voltage-stabiliser tube for use.R5 selects 4M Ω for use.R6 selects 330K Ω for use.C4 selects 333J/50V for use.
