Description
Technical field
The present invention relates to the connection control device of a kind of electric car power supply control setup, particularly a kind of electronlmobil and domestic power supply.
Background technology
Along with the development of New-energy electric vehicle technology, more and more electronlmobil enters common people family.At present, the charging corollary equipment construction of electronlmobil relatively lags behind, and most electronlmobil can only charge on the charging pile meeting national standard, common domestic power supply can not to charging electric vehicle, therefore user wants to go charging to fixing several battery-charging statioies to battery-driven car charging and domestic power supply can not be utilized to charge, and so just limits the universal of electronlmobil and development.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the invention provides a kind of domestic power supply that can utilize to the connection control device of the electronlmobil of charging electric vehicle and domestic power supply.
The object of the present invention is achieved like this: the connection control device of a kind of electronlmobil and domestic power supply, be made up of vehicle-mounted computer and the power circuit be attached thereto thereof, sound light alarming circuit, display circuit, characterized by further comprising button inputting circuits, charging connection signal has confirmed circuit and charging current control circuit, button inputting circuits is by be connected with vehicle-mounted computer and button switch parallel with one another forms, and each button switch is all connected with the resistance of ground connection; Charging connection signal confirm circuit by two mutually serial connection resistance and be connected to resistance two ends and two of ground connection electric capacity are formed; Charging current control circuit comprises resistance and aerotron, and one of them resistance is connected between vehicle-mounted computer and the base stage of aerotron, and another resistance is connected to transistor emitter and ground connection.
Described power circuit is connected and composed by AC/DC conv and DC/DC conv.
Described sound light alarming circuit is connected and composed by light-emitting diode, buzzer phone and resistance.
Described display circuit is made up of LCD LCD MODULE.
The present invention simulates the charging pile connection control signal of Standard, thus enable battery-driven car be connected to domestic power supply, according to the power requirement of different domestic power supply adjustment charging current, and can have human-computer interaction function, user is adjustable adjusts the size of charging current as required.Structure of the present invention is simple, safe and convenient to use.
Accompanying drawing explanation
Fig. 1 is schematic circuit diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, be made up of vehicle-mounted computer ECU and connected power circuit, sound light alarming circuit, display circuit, button inputting circuits, charging connection signal confirmation circuit and charging current control circuit.
Button inputting circuits is by be connected with vehicle-mounted computer ECU and button switch K1, K2, K3, K4 parallel with one another forms, each button switch is all connected with resistance R1, R2, R3, R4 of ground connection, in four buttons, K1 is that electric current adds button, K2 is that electric current subtracts button, K3 for arranging button, K4 for showing switching key.
Charging connection signal confirm circuit by two mutually serial connection resistance R7, R8 and be connected to resistance R8 two ends and electric capacity C1, C2 of ground connection are formed, by the magnitude of voltage reading CC point, ECU confirms whether charge cable is connected with electric automobile, when cable does not have a connecting electric automobile, the voltage of CC point is a fixed value, after cable is connected to electronlmobil, the voltage of CC point is another one fixed value, just can judge whether charge cable is connected to electronlmobil when ECU detects the change of voltage.
Charging current control circuit comprises resistance R9, R10 and aerotron Q1, wherein resistance R9 is connected between the base stage of vehicle-mounted computer ECU and aerotron Q1, resistance R10 is connected to transistor emitter and ground connection, ECU sends the pwm signal of a 5V, by the amplifying circuit be made up of Q1, R9, R10, become the pwm signal of 12V, its dutycycle after battery charger receives this pwm signal, can be detected, the larger charging current of dutycycle is larger, and the less charging current of dutycycle is less.
Power circuit is connected and composed by AC/DC conv and DC/DC conv, the alternating current of 220V is converted to 12V direct current (DC) by AC/DC, connect for charging and confirm circuit and current control circuit, 12V direct current (DC) is converted to 5V direct current (DC) by DC/DC, to ECU, key-press input, sound and light alarm and display electrical current.
Sound light alarming circuit is connected and composed by light-emitting diode L1, buzzer phone B1 and resistance R6, and when system monitoring is to fault, the light of being sounded by warning circuit and glimmering, shows concrete defect content simultaneously on a liquid crystal display.
Display circuit is made up of LCD LCD MODULE, can show charging coupled condition, charging current, failure message etc.
