Utility model content:
Technical problem to be solved in the utility model is to provide the control system of the electric vehicle alternating-current charging equipment that high, old of a kind of stability is low, area occupied is little.
The utility model technical solution problem, adopts following technical scheme:
Without the control system of the electric vehicle alternating-current charging equipment of microprocessor, it is characterized in that: comprise timer chip, amplifier chip, CP line, current rectifying and wave filtering circuit, two-way comparator and charge switch indicating lamp module, the described input of amplifier chip is connected with the output of timer chip, described CP line is connected to the output of amplifier chip, the collection terminal of described current rectifying and wave filtering circuit is connected with product line, the described input of two-way comparator is connected with the output of current rectifying and wave filtering circuit, described charge switch indicating lamp module is connected with the output of two-way comparator.
Described charge switch indicating lamp module comprises charge switch and indicator light, and described indicator light comprises red yellowish green trichromatism lamp.
Timer chip produces initial PWM ripple and passes to amplifier chip, amplifier chip outputs on CP line after being amplified by PWM ripple signal, current rectifying and wave filtering circuit is at CP line up-sampling and give two-way comparator after PWM ripple is filtered into stable level and do voltage-contrast, and 2 comparing results of generation control the action of charge switch and status indicator lamp in the form of a signal.
The beneficial effects of the utility model are:
Stability is high: integrated circuit exists without any software logic, when external disturbance, does not have deadlock, runs the phenomenon flown, guarantee that the charging circuit moment is in correct control;
With low cost: the device price needed for whole circuit realiration is all lower than 1 yuan;
Circuit board area occupied is little: the integrated circuit of use is the paster encapsulation of 8 pins, and size is 6mm*6mm, and the area of whole circuit board can accomplish below 70mm*70mm, in the cabinet of charging device, only take very little space.
Accompanying drawing illustrates:
Fig. 1 is the utility model circuit theory schematic diagram.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, without the control system of the electric vehicle alternating-current charging equipment of microprocessor, comprise timer chip, amplifier chip, CP line, current rectifying and wave filtering circuit, two-way comparator and charge switch indicating lamp module, the input of amplifier chip is connected with the output of timer chip, CP line is connected to the output of amplifier chip, the collection terminal of current rectifying and wave filtering circuit is connected with product line, the input of two-way comparator is connected with the output of current rectifying and wave filtering circuit, and charge switch indicating lamp module is connected with the output of two-way comparator.
Charge switch indicating lamp module comprises charge switch and indicator light, and described indicator light comprises red yellowish green trichromatism lamp.Green light indicating equipment works on power, and red light indicating equipment has started to power to charging socket, and amber light instruction vehicle is full of, charging socket is stopped power supply.
Timer chip produces the pwm signal of 1KHz 5V by adjusting peripheral resistance capacitance.
Amplifier chip change into after the signal of timer is compared 12V pwm signal and output on CP line.
Current rectifying and wave filtering circuit carries out rectifying and wave-filtering after CP line up-sampling, and PWM ripple is converted into DC level.
Two-way comparator will compare DC level, and whether decision level is 9V and 6V, when level is 9V or lower, represent that charging socket has been connected with charging plug and has outputed signal; Represent that when level is 6V or lower vehicle has allowed charge and output signal.
The comparative result of comparator determines whether charge switch powers, which kind of color indicator light shows.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
