The environmental problems such as haze.In recent years, the development of domestic electric car was in explosive growth, however, since urban land is in short supply and electric
Cable road improvement expenses are higher, so that the serious lag of charging pile construction, causes electric car charging inconvenient, it is serious to restrict electricity
The development of electrical automobile is combined using charging pile with conventional road lamp to efficiently utilize urban land there has been proposed various
Form is transformed on public lighting circuit, however, being difficult since public lighting circuit power is smaller if not carrying out the system reform
Realize high power DC charging.Therefore, how technological innovation is carried out on existing supply network, enable charging unit can be with
It is directly attached, and the unstable power conversion in some sources can be discharged for a kind of stable with high with these power supplys
The energy source of power feeds convenient for the charging of electric car, improves the popularization and application of electric car.
At this stage, electric car has obtained the support energetically of national governments, is rapidly developing, while having driven electronic vapour
Vehicle charging equipment is greatly developed.Electric automobile charging pile is divided into alternating-current charging pile and direct-current charging post, and alternating-current charging pile is vehicle
It carries charger and the energy is provided, carry out long-time charging, direct-current charging post is non-on-board charger charging, carries out quick charge.It is existing
Some direct-current charging posts have many shortcomings, and charging pile operating system can only be interacted by single mode with user,
It is unable to complete the concentrated collection to battery parameter, presents；Charging process can not be monitored in real time, charging rate is lower.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the above technological deficiency, it is fast to provide a kind of charging rate, can be used more
Mode is interacted with user, the electric car direct current quick charge stake system that can be monitored in real time.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of electric car direct current quick charge stake
System, including direct current quick charge stake, user interface, central control unit, energy-storage units, bidirectional converter and electronic vapour

Current transformer is electrically connected with direct-current charging interface of electric automobile and energy-storage units respectively.
As an improvement, the user interface include key-press input, inquiry about charging, inquiry into balance, metering ammeter and
Card reader, design is in this way convenient for real time monitoring.
As an improvement, the energy-storage units include battery group and the battery management list for management of battery group
Member, the battery group and bidirectional converter are electrically connected, the battery management unit respectively with battery group and in
The connection of control unit signal is entreated, is designed in this way in order to which the energy-storage units energy storage effect made is more preferable.
As an improvement, the battery group is lithium iron phosphate storage battery group, it can be conducive to improve working performance and make
Use the service life.
After using the above structure, the present invention has the advantage that charging rate is fast, multimode can be used and handed over user
Mutually, it can monitor in real time.First when charging is required, charging cable connecting electric automobile is exchanged into electrical interface, user exists IC card
It swipes the card in card reader, and by key-press input password, information input correctly observes electricity remaining sum by metering ammeter afterwards, so
After select charge mode, charge mode to determine after can issue signal to central control unit, central control unit passes through control
Bidirectional converter issues signal to energy-storage units, and direct current is sent to electric car DC charging from energy-storage units by bidirectional converter
Interface.
