Description
The application is for dividing an application, and the application number of original application is 2011104203302, and the applying date is 2011-12-15, and denomination of invention is a kind of charging station charge metering system and metering method.
Technical field
The present invention relates to a kind of charging station that charging service is provided for electric vehicle, relate in particular to charge metering system and the metering method of charging station.
Background technology
Along with increasingly increasing the weight of of global energy crisis; countries in the world all make great efforts to seek to save energy and reduce the cost, the recycling approach of the energy and the cleanliness without any pollution energy; automobile is as the indispensable vehicles of people's daily life; its energy consumption is polluted huge; electric power is more and more favored as a kind of clean energy resource, and each large automobile manufacturing enterprise of the world also all comes progressively replacing fuel oil power vehicle at effort research and development electric automobile.
Electric automobile refers to utilize the electric energy in the rechargeable battery/electric battery that is stored in vehicle that power-actuated automobile is provided.Generally, the battery of electric automobile is undertaken realizing recharging after one section charging effective time by being connected to the charging device of electrically-charging equipment.Under existing environment, the charging electric vehicle facility that certain scale occurred, but electric automobile large-scale universal has been subject to the restriction that electrically-charging equipment function and quantity lack, need the electrically-charging equipment more extensive, that function is more complete that distributes, and the common electric vehicle charging time is longer, usually be chosen in night or electric automobile charges in sufficiently long situation down time, further need to allow the long-time electrically-charging equipment that stops of vehicle.Although there are now some charging stations to adopt the mode of large current charge to shorten the duration of charging, to alleviate the charging demand, yet in the ordinary course of things, the charging electric vehicle facility all utilizes the 220V civil power as electric power source, duration of charging can be controlled at 4 to 6 hours, and 150 to 600A large electric current namely allows to reduce the duration of charging, but cause electrical network unstable, and the concentrated charging of large electric current probably causes platform district momentary load excessive and cause outage, can shorten the batteries of electric automobile life-span simultaneously, therefore this mode and inadvisable.
Secondly, now in technology the charge metering system of electrically-charging equipment still exist some defectives.For example, a kind of charge billing system of charging station is disclosed in Chinese patent ZL200810059392.3, it mainly comprises charging set, AC energy gauging table, direct current energy gauging table and charging station management computer, charging inlet comprises car load charging inlet and single-phase standard battery module charging inlet, described charging station management computer is connected with printer and GPRS communication transceiver, and data telecommunication line is 485 lines.It utilizes three-phase alternating current network to realize charging accounting for electric automobile; simultaneously cost information and user profile are transferred to terminal server; but technique all is not described in detail concrete structure and charging, communication process; also mention some defectives that exist in technology now; therefore factors such as duration of charging, fault recognition, earth leakage protection, lightning protection can't fundamentally solve or alleviate a difficult problem that exists in prior art.
Moreover, as a kind of consumer service unit, user's experience is also a key factor, in existing situation, generally that the electric automobile user selects the electrically-charging equipment of bee-line to charge according to the electric weight of battery, and as mentioned above, may exist the excessive situation of some charging station demand to occur.And particularly in remote districts, especially underpopulated area, the environmental factor such as weather, temperature is comparatively abominable in addition, set up the electrically-charging equipment cost higher, so charging station negligible amounts, if and electrically-charging equipment can not carry out the improvement creation of intellectuality, hommization, will certainly cause damage to the user.In addition, even in the city, how to avoid electrically-charging equipment to have the situation of blocking up, reasonable arrangement and the charging of scheduling battery must be sought a kind of user of making and seek in real time electrically-charging equipment, and error free, fast electrically-charging equipment communication network.
Again, it is regional that electrically-charging equipment belongs to the high pressure electricity consumption, similar with the refuelling station, need to rationally supervise power source, especially in remote districts, can not rely on fully and manually realize supervision.For example the user comes in contact with electrically-charging equipment in the power purchase process, and therefore the hidden danger that exists high pressure to get an electric shock also must be considered perfect to the design of electrically-charging equipment.
The most importantly, one of major function of electrically-charging equipment is that the purchase of electricity to the electric automobile user realizes instant accurate measurement, and information exchange is crossed communication network is sent to server terminal and carries out data and gather.At fuel-engined vehicle gradually under replaced trend, the requirement of electrical network is also increased gradually, how to realize that effective errorless communication is a difficult problem of electrical network now, and need to implement distributing electric power according to the rational management of statutory regulation or power department.Can find out from foregoing description, communication network is a requisite part of electric automobile recharging system, and it must satisfy the demand of electric automobile user, electrically-charging equipment supvr, Utilities Electric Co. and government department.Current common technique is to realize carrier communication by power line communication technology, for telling of mass data transmitted, and the inferior position that is restricted to transmission range of this technology.Can connect terminal server with wired local area network in addition, the difference of cable LAN and PLC network is to carry signal of communication with dedicated line, and Ethernet is exactly the most general technology, but technique needs exclusive track laying, and cost is higher.and Wide Area Network is the widest computer network of coverage, currently begun to utilize WAN, for example the Internet network is realized data communication, but this technology village problem comparatively general: data are that the form with the enciphered data package is sent to the main website computer, usually like this, can there be network delay, the problem of broken string or corrupted data, and these problems appear at user terminal usually---the integrated system of electrically-charging equipment, also as previously described problem, the level of integrated system imperfection of charging system, design inadequate hommization, just can cause the generation of problems.
Become the theme of China's economic development along with low-carbon economy, electric automobile is as the important component part of new forms of energy strategy and intelligent grid, and one of the strategic new industry determined of State Council, will become the emphasis of Chinese Automobile Industry ' and energy industry development from now on.Yet ev industry is a systematic engineering of business, and electric automobile charging station is one of key link, must realize common coordinated development with the electric automobile other field.Therefore, need the charging electric vehicle facility of a kind of high integration, appropriate design, to solve above-mentioned technical barrier, when effectively utilizing power network resources, realize user's convenient use.
