Abstract

The utility model discloses a novel electric vehicle charging plug. The circuit principle is: commercial power accessing AC end of J1 and J2; the voltage of the commercial power is reduced by the R1C1, commutated by the D1-D4; D5 generates 12V power source by the voltage regulation; supplying the power to the relay and the back level circuit for working; the 12V power source generates +5V power source by the U1 (78L05) voltage regulation for the work of the single chip machine U2. the charging plug has 8 hours default, timing and time-selecting functions, using the single chip machine design; controlling function is improved and the timing time is precise, which solves the control problem of the time during the charging process. The utility model can randomly arrange the charging starting time and the stopping time according to the charging request of the battery.

Description

A kind of novel electric vehicle charging plug

Technical field

The utility model belongs to the motor machine field, relates in particular to a kind of charging plug that is used on the electric car charger.

Background technology

At present, all chargers can continue low current charge to battery after being full of electricity, one to fill be exactly an evening, battery produces a large amount of gases, strengthened the liquid loss of battery, and air scour battery pole plates active material, cause it soft and come off, seriously shortened the life-span of battery, so that the battery in the industry fills bulging phenomenon is many especially, battery life is subjected to shortening in various degree, also there is not a charger to cut off the power supply automatically now, green light is bright is that the expression battery has been full of, rather than has cut off the power supply and do not filled, and has a strong impact on the useful life of battery so if things go on like this.

Summary of the invention

The purpose of this utility model be exactly at existing electric car charger exist can not be artificial when the charging control charging interval problem, provide a kind of can the automatic setting charging interval, the time of arrive setting will cut off the power supply automatically, prevented inside components and parts that long-time charging causes burn out with signal drift after to the injury of battery.

The purpose of this utility model is to realize like this, this novel electric vehicle charging plug circuit theory is: civil power inserts the AC end of J1 and J2, civil power is through the R1C1 resistance-capacitance depressurization, the D1-D4 rectification, the D5 voltage stabilizing produces the power supply of 12V, supply with relay and late-class circuit work, the 12V power supply is supplied with single-chip microcomputer U2 work through U1 (78L05) voltage stabilizing generation+5V stabilized voltage power supply, the external delay adjustments switch of 6 pin of U2, in 10 seconds wait setting-up time behind the opening initialization, press the delay adjustments button to set the time-delay charging interval, whenever press once this key delay time and increase by one hour, the time dalay indicator light that 7 pin of while U2 connect (external) has corresponding flicker number of times indication, and delay time is by " 1H-2H-3H........7H-0H " cycle sets; Button is set in the external timing charging of 5 pin of U2, in 10 seconds wait setting-up time of opening initialization, press the timing setting button to set the quantitative charging interval, whenever press once this key timing and increase by 1 hour, the timing indicator that 3 pin of while U2 connect (external) has corresponding flicker number of times indication, and timing is by " 1H-2H-3H........7H-8H " cycle sets; In 10 seconds wait setting-up time of opening initialization, press as if no button, then the system default state is regularly charging in 8 hours, no actuation of keys after 10 seconds system enter the mode of operation control charging process of setting, this moment, 2 pin of U2 were exported high level, drive the relay adhesive through Q1, to the charger power supply, charger is started working, after finishing the control procedure of setting, the 3 pin output low levels of U2, relay discharges, and cuts off the power supply of charger, finishes whole charging control process.

Owing to adopt above designed lines, this charging plug has 8 hours acquiescences, three functions regularly and when selecting, the design of employing single-chip microcomputer, controlled function is perfect, timing is accurate, has well solved the time control problem in the charging process, can set the zero-time and the termination time of charging according to the charging needs of battery arbitrarily.
