Abstract

The utility model relates to a self cutting-off battery charging socket which belongs to the technical field of intelligent electrician electric appliances, and comprises a casing, a jack of a conductor, which is arranged on the casing, and a conductor wire whose one end is connected with a plug. Two routes of rectifying and filtering voltage stabilizing circuits are arranged in the casing and comprise a photoelectric isolation transport module of a peripheral circuit, a numerical code operational amplification module, a relay circuit and a sampling circuit. A micro-computer chip is arranged in the casing of the socket to intelligently judge the magnitude of the charging current and automatically cut off the charging power supply by utilizing the characteristic that a charger keeps low current battery charging to an electric bicycle after the battery charging of the electric bicycle is finished, so the sharp decline of batteries is avoided, the service life of the batteries are prolonged, the charger is protected and the service life of the charger is prolonged. Simultaneously, the utility model can also save energy and reduce the consumption, which reduces the use cost of consumers. The utility model is a new member of the socket family, which is especially suitable for the battery charging of electric vehicles and has obvious economical and social benefits.

Description

From outage battery charge socket

Technical field

The utility model relates to a kind of from cutting off the power supply the battery charge socket, belongs to intelligent electrician's technical field of electric appliances.

Background technology

Electric bicycle charging is that the end with charger is connected with the battery of electric bicycle, the other end is inserted on the existing general socket, after the electric motor car charging is finished, charger can not initiatively cut off charge power supply, keep battery of electric bicycle is carried out low current charge always, cause overcharging easily like this, overcharge and then can cause the battery dehydration, this is the formidable enemy of lean solution formula maintenance-free battery, because the existing electrolyte of lean solution formula maintenance-free battery own is just few, can not open again to close and cover liquid feeding, battery is sharply decline easily, shortens battery life; In addition, most of battery charge are carried out at night, because night, voltage raise and fluctuation easily, after this moment, charging was finished, as untimely powered-down, charger also burnt out easily.

Summary of the invention

The purpose of this utility model is all can not cut off charge power supply automatically at the charger and the general socket that have electric bicycle now after charging is finished; keep battery is carried out low current charge always; thereby cause battery sharply to fail; shorten battery life; the deficiency that charger also burns out easily; provide can not only prolong battery useful life, protection charger safety, and energy-conservation economize on electricity is a kind of from cutting off the power supply the battery charge socket.

The purpose of this utility model is achieved through the following technical solutions, a kind of from cutting off the power supply the battery charge socket, comprise housing, have the jack of conductor and the lead that an end is connected with plug on the housing, be provided with the two-way rectification filtering voltage stabilizing circuit that connects power supply altogether in the housing, the output of one road rectification filtering voltage stabilizing circuit connects the photoelectricity isolated transmission module of setting, the source end of digital computing amplification module, the output of another road rectification filtering voltage stabilizing circuit connects the relay circuit of setting, two jacks, one hole of housing connects negative source end, another hole connects the positive source end that string has sample resistance and relay contact, the two ends of sample resistance connect the input of photoelectricity isolated transmission module behind rectifying and wave-filtering, appliance circuit is succeeded in the output of digital computing amplification module.

After the utility model utilizes charging battery of electric vehicle to finish; charger still keeps battery of electric bicycle is carried out this characteristic of low current charge; the size of microcomputer chip intelligent decision charging current is set in Socket casing; automatically cut off charge power supply; both can avoid the rapid decline of battery; prolong the useful life of battery; can protect charger safety again; prolong the useful life of charger; also can save energy simultaneously, reduced consumer's use cost, the utility model is the newcomer of socket family; be particularly useful for charging battery of electric vehicle, have remarkable economic efficiency and social benefit.

Embodiment

The utility model is connected with the lead of plug by a jack that has conductor on housing, the housing and an end, two-way rectification filtering voltage stabilizing circuit in the housing, comprise the photoelectricity isolated transmission module of peripheral circuit, digital computing amplification module, relay circuit and sample circuit are formed, rectification filtering voltage stabilizing circuit, relay circuit and sample circuit are existing mature technology, the two-way rectification filtering voltage stabilizing circuit connects power supply, capacitor C altogether ₁Be dividing potential drop electric capacity, rectifier diode D ₁, D ₂, D ₃, D ₄Form bridge rectifier, through capacitor C ₂With voltage-stabiliser tube WD1 filtering voltage regulation, give to comprise the photoelectricity isolated transmission module of peripheral circuit, the power supply of digital computing amplification module; Capacitor C 7 is a dividing potential drop electric capacity, rectifier diode D ₉, D ₁₀, D ₁₁, D ₁₂Form bridge rectifier, through capacitor C ₆With voltage-stabiliser tube WD ₂Filtering voltage regulation, to the relay circuit power supply, relay circuit is made up of relay J and triode Q2, and the contact of relay J is serially connected in the positive end loop of socket one jack; The resistance R 1 of sample circuit is serially connected in the positive end loop of socket one jack together with the normally-closed contact of relay J, and two terminations of sample circuit resistance R 1 are by diode D ₅-D ₈The bridge rectifier of forming, its output connects the input of photoelectricity isolated transmission module, and the input of digital computing amplification module is connected to push-button switch between over the ground, and the base stage of triode Q2 in the appliance circuit is succeeded in the output of digital computing amplification module.

S presses when push-button switch, digital computing amplification module IP ₂NE555 (HEADER ₄X ₂) 2,6 pin become low level, its 3 pin becomes high level, makes the triode Q2 in the relay circuit saturated, relay is failure to actuate and is in normally off, has connected socket power, delays time after 2-3 minute, as not charging, then cuts off the power supply of socket automatically

As charge the battery, charging current is by resistance R 1 in the sample circuit, and the resistance of resistance R 1 is 1-2 Ω, and energy consumption is very little, the interchange pressure drop that produces produces direct voltage by the rectification of diode D5-8, and d. c. voltage signal is through photoelectricity isolated transmission module DPI 4N25 (HEADER ₃X ₂) isolation and transmission, make digital computing amplification module IP ₂NE555 (HEADER ₄X ₂) 6 pin a low level has been arranged, cause its 3 pin to produce high level, make the triode Q2 in the relay circuit saturated, relay still is failure to actuate and is in normally off, keeps socket power not to be cut off.

Finish as battery charge, have only very little charging current this moment, produce very little interchange pressure drop, digital computing amplification module IP by resistance R 1 in the sample circuit ₂6 pin do not had low level, delay time after 2-3 minute, cause its 3 pin to produce low level, triode Q2 in the relay circuit is ended, and the actuating of relay disconnects the contact that is in normally off, cut off the circuit of jack in the socket, make the socket dead electricity, the power supply of charger is closed, and realizes intelligently connecting or disconnecting.
