Background technology
Along with the national economic development, the income of residents improves, and private car is more and more, and is therefore also just increasing to the demand of the energy.Yet using the automobile of oil is one of chief culprit of urban air pollution, also is the key factor that constitutes global warming.For energy-saving and emission-reduction, the protection atmospheric environment uses clean energy resource to become current inexorable trend.Be that the electric automobile of power source can reduce the air pollution to the city with the electric energy, improve urban air-quality, therefore extensively be subjected to advocating of people.In order to allow electric automobile fill electricity easily with, current pressing for developed a kind of outdoor ground of parking provides the charging service at any time for charging electric vehicle device that is installed on.
Summary of the invention
The technical problem to be solved in the present invention is, backward situation at the prior art facility, a kind of outdoor ground of parking provides the charging service at any time for charging electric vehicle device that is installed on is provided, it is alternating current power supply charging pile of electric automobile, utilize this device users only need plug the electricity card and just can be the charging electric vehicle of oneself, charging process need not artificially be controlled, and finishes charging back electricity card and also can show dump energy.
Technical solution of the present invention is, described alternating current power supply charging pile of electric automobile, referring to Fig. 1, it has a control system 7 as shown in Figure 1, is connected in parallel to AC power 1, leakage current sensor 2, ammeter 3, LCDs 4, data transmission module 5 and memory 6 on this control system 7.Wherein said AC power 1 electricity connects the power input of described control system 7; The digital-to-analogue that described leakage current sensor 2 electricity connect described control system 7 transforms input; Described ammeter 3 electricity connect 485 interfaces of described control system 7; Described LCDs 4 electricity connect the data bus terminal of described control system 7; Described data transmission module 5 electricity connect 232 interfaces of described control system 7; Described memory 6 electricity connect the data input/output terminal of described control system 7.
Operation principle of the present invention and method of work be, described control system 7 can be used to carry out data acquisition as core controller, and it has deal with data simultaneously, transmission data and the function that judges according to the data of being gathered.This charging pile inserts the AD converter input channel by transducer and transforms the gained digital value and realize the corresponding protection function, and then by with set critical value relatively judge whether break down.Described leakage current sensor 2 is used for detecting the size of leakage current.The data communication method of this charging pile comprises 485 buses, CAN bus and GPRS wireless network.Described ammeter 3 promptly adopts 485 buses with the communication of control system 7; Be arranged at and adopt CAN bus or Internet bus or 485 buses or less radio-frequency to connect between the adjacent charging pile control system 7 in same place; Utilize the contact of GPRS wireless network between charging pile and its backup server.In order to prevent the generation of stealing electricity phenomenon in the charging process, can adopt electric lock to pin charging plug, capable again release after the power taking of user's plug-in card.Charging pile can be closed output if integral body breaks down, and stops the charging of user's plug-in card, and display reminding is spoken on LCDs 4.
The invention has the beneficial effects as follows:
1), in public building such as office building, market, parking lot or charging station, can directly charge for electric automobile or other vehicle-mounted charge machine that needs charging;
2), power can reach 7KW;
3), charging process controls automatically, need not the user keep an eye on, can be the user and save time.
