Description
Technical field
The present invention relates to a kind ofly, relate in particular to the charging metering system and the metering method of charging station for electric vehicle provides the charging station of charging service.
Background technology
Along with increasing the weight of day by day of global energy crisis; Countries in the world are all at the approach and the cleanliness without any pollution energy of making great efforts to seek to save energy and reduce the cost, the energy can utilize again; Automobile is as the indispensable vehicles of people's daily life; Its energy consumption is polluted huge, and electric power is more and more favored as a kind of clean energy resource, and each big automobile manufacturing enterprise of the world also all comes progressively to substitute the fuel oil power vehicle at effort research and development electric automobile.
Electric automobile is meant that the electric energy that utilizes in the rechargeable battery/electric battery that is stored in vehicle provides power-actuated automobile.Generally, the battery of electric automobile carries out one section charging back realization effective time and recharges through being connected to the charging device of electrically-charging equipment.Under existing environment; The charging electric vehicle facility that certain scale occurred; But large-scale popularize of electric automobile received electrically-charging equipment function and the restriction that quantity lacks, and need the electrically-charging equipment that distribution is more extensive, function is more complete, and the common electric vehicle charging time is longer; Usually be chosen in night or electric automobile charges under the sufficiently long situation down time, then further need to allow the long-time electrically-charging equipment that stops of vehicle.Although there are some charging stations to adopt the mode of large current charge to shorten the duration of charging now; With alleviation 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; Even and 150 to 600A big electric current can reduce the duration of charging, but cause electrical network unstable, and the concentrated charging of big electric current cause platform district momentary load excessive and cause outage probably; Can shorten the batteries of electric automobile life-span simultaneously, therefore this mode and inadvisable.
Secondly, the charging metering system of electrically-charging equipment still exists some defectives in the technology now.For example; A kind of charge billing system of charging station is disclosed among the 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, and said 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 this technology is not all made detailed description to concrete structure and charging, communication process; Also mention some defectives that exist in the technology now,, therefore can't fundamentally solve or alleviate a difficult problem that exists in the prior art such as factors such as duration of charging, fault recognition, earth leakage protection, lightning protections.
Moreover; As a kind of consumer service unit; User's experience also is a key factor, under existing situation, generally is that the electric automobile user selects the electrically-charging equipment of bee-line to charge according to the electric weight of battery; And, possibly exist the excessive situation of some charging station demand to take place as mentioned above.And particularly in remote districts; Especially underpopulated area; Environmental factor such as weather, temperature is comparatively abominable in addition, and it is higher to set up the electrically-charging equipment cost, so the charging station negligible amounts; And electrically-charging equipment then will certainly cause damage to the user if can not carry out the improvement of intellectuality, hommization creates.In addition,, how to avoid electrically-charging equipment to have the situation of blocking up, rationally arrange and dispatch battery charge, must seek a kind of user real time that makes and seek electrically-charging equipment even in the city, and error free, fast electrically-charging equipment communication network.
Once more, electrically-charging equipment belongs to high pressure electricity consumption zone, and is similar with the refuelling station, need rationally supervise power source, especially in remote districts, can not rely on manual work to realize supervision fully.For example the user comes in contact with electrically-charging equipment in purchasing electric process, and therefore the hidden danger that then 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 electric automobile user's the electric weight of purchasing is realized instant accurate measurement, and information is sent to server terminal through communication network carries out data and gather.Under the trend that fuel-engined vehicle is replaced gradually, the requirement of electrical network is also increased gradually, how to realize that effective errorless communication then is a difficult problem of electrical network now, and need implement distributing electric power according to the rational management of statutory regulation or power department.Can find out that from foregoing description communication network is a requisite part of electric automobile recharging system, 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 through power line communication technology, and for telling of mass data transmitted, this technology limitation was the inferior position of transmission range.Can use wired local area network to come the connecting terminal server in addition, the difference of cable LAN and PLC network is to use dedicated line to carry signal of communication, and Ethernet is exactly the most general technology, but the exclusive track laying of this Technology Need, 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 technological village problem comparatively general: data are that the form with the enciphered data package is sent to the main website computer; The common like this problem that can have network delay, broken string or corrupted data; And these problems appear at user terminal usually---the integrated system of electrically-charging equipment, and also as the described problem of preamble, the level of integrated system imperfection of charging system; Design not enough hommization, just can cause the generation of this type of problem.
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 confirmed of State Council, will become the emphasis that Chinese Automobile Industry ' and energy industry from now on develop.Yet ev industry is a systems engineering, 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,, when effectively utilizing power network resources, realize user's convenient use to solve above-mentioned technical barrier.
