Pond connection, the detection chip on power grid supply side route can pass through any one volume of the prior art for detecting mains frequency
Cheng Yuyan is programmed in controller, to set mains frequency threshold value and be used to compare the power grid frequency that detection chip detects
Comparison result instruction is sent to AC/DC converter and executed, for example, mains frequency threshold value is set as 50Hz, works as detection chip by rate
(peak of power consumption, power grid electricity shortage, which are shown to be) when detecting the substandard 50Hz of supply side mains frequency then passes through AC/DC
Part electricity in battery is supplied to power grid by converter；When mains frequency is higher than the 50Hz of standard (it is shown to be low power consumption,
Grid power is rich) it will then be charged to battery by the electricity that AC/DC converter absorbs power grid.
Further, the control panel with controller signals transmission is installed in housing outer surface.On the control panel may be used
Working method to select charging unit: in a manner of fast charge mode, trickle charge, automated manner.Fast charge mode therein is exactly with battery
The maximum current of permission carries out quick charge mode；Trickle charge mode is exactly that user sets charging time section progress normal charge at a slow speed
Mode；Automated manner is exactly device while completing charge function, automatically selects the working method supported with power grid close friend.
The state of mains frequency variation and battery that controller measures under automated manner according to detection chip, control
AC/DC converter works in charge or discharge mode, and selects different working current values.
Further, it is also equipped with wireless communications chips connected to the controller inside housings.User can also move
Terminal and the wireless communications chips establish connection, set working method, the mains frequency of charging unit on mobile terminals in this way
The minimum electricity percentage value of threshold value, charging and discharging currents threshold value, battery.
Further, enclosure interior is also equipped with bidirectional measuring voltameter, and bidirectional measuring voltameter and AC/DC converter connect
It connects, transmitted with controller signals.If electricity from power grid " peak " period to power grid that battery can be sent in of bidirectional measuring voltameter
Amount and power grid " paddy " period absorb electricity measure respectively it is clear, for distinguish calculating revenue and expenditure the electricity charge.
Further, heat release hole is also provided in housing outer surface.The heat release hole added effectively helps the device at work
Distribute the waste heat of generation.
By adopting the above technical scheme, beneficial effect of the present invention includes: that a large amount of accumulator of electric car becomes Pang to the present invention
Big energy-storing container, using the present invention for the device to accumulator of electric car charge and discharge, when there is a large amount of device on power grid
In application, being achieved that the automatic adjustment in user side to power load, act on, first is that reducing power grid peak-valley difference, alleviates
The scheduling pressure of power grid；Two are reduction of block supply capacity requirement.It may be implemented using technological means of the invention electronic
Automobile storage battery is interacted with the close friend of power grid, while ensureing user's economic interests, realizes that the close friend of battery and power grid is mutual
It is dynamic, realize the peak load shifting to power grid.
