It changes.The present invention solves the problems, such as that electrical changing station night power idle and charging station vacancy rate on daytime are high, and solves more vehicles while filling
The problem of electricity, and when guaranteeing charging, effective power distribution is carried out between charging pile, realizes the efficient utilization of resource.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and embodiments:
Fig. 1 is the functional block diagram of the power shared system for electric charging station of the invention.
Specific embodiment
As shown in Figure 1, the power shared system for electric charging station of the invention, including charger, n are changed battery
Group, m charging pile and monitoring device；The charger includes n AC/DC charging module, the n AC/DC charging module
Electric battery pack is changed by the one-to-one connection of contactor K1-Kn respectively, and each AC/DC charging module passes through m contactor respectively
It is connect with all charging piles, each contactor forms contactor matrix；The monitoring device respectively changes electricity by CAN bus connection respectively
Battery pack, charging pile, AC/DC charging module control each contactor by switch control unit connection；Monitoring device passes through control
Contactor realizes charger output power in the switching changed between electric battery case or charging pile, by the defeated of AC/DC charging module
It is assigned to out and changes electric battery pack or different charging piles.The present invention realizes the switching for changing battery pack between the pile body that charges, and
Realize more and meanwhile charging and power dividing function.
Power shared system of the invention and function are described in detail below with reference to practical application:
Mode 1: it exchanges electric battery pack and charges
After electricity changing robot completion changes electrically operated, battery to be charged is placed in charging rack.Monitoring device collects battery pack shape
The corresponding AC/DC charging module of this group of charging rack and output contactor are controlled after state, realize the control of output power.Charging process
In, real-time monitoring AC/DC charging module and switch control unit (contactor matrix) state, it is ensured that AC/DC charging module and cut
Change control unit (contactor matrix) state.
Mode 2: having idle power, and 1 trolley accesses charging pile
When system has idle power (single group exports electric current A, total to export electric current X), when there is vehicle to access charging pile, monitoring device
The idle AC/DC charging module of control and corresponding output contactor are exported to corresponding pile body, meet the charge requirement of access vehicle.
In charging process, monitoring device real-time monitoring AC/DC charging module and output switch control unit (contactor square
Battle array) state.According to current needs, as charging demand current I > X, all idle AC/DC charging module is put into.As I < X-A
When, one group of AC/DC charging module is cut off, monitors charging current in real time, repeats the operation until charging complete.Realize the dynamic of power
State distribution, improves module efficiency and utilization rate.
Mode 3:1# charging pile is non-to vehicle to charge at full capacity, and 2# charging pile accesses vehicle two
It charges at full capacity when 1# charging pile is non-to vehicle, when system has idle power (single group exports electric current A, total to export electric current X),
2# charging pile accesses vehicle two, the monitoring unit AC/DC charging module idle according to the control of two demand information of vehicle, and controls and cut
Control unit (contactor matrix) is changed by AC/DC charging module and 2# charging pile connection, is charged to vehicle two.When demand electricity
When flowing I > A, and still having idle AC/DC charging module, then put into one group of module；The operation is repeated, until filling without idle AC/DC
When electric module, current state is kept.When more charging piles charge simultaneously, by charge control queue priority, same operation.
Mode 4: charging at full capacity to vehicle one, the access charging of vehicle two
When 1# charging pile charges at full capacity to vehicle one, if 2# charging pile accesses vehicle two, no matter two demand current I of vehicle
To be how many, system automatically cuts off last group of AC/DC charging module of 1# charging pile from 1# charging pile, puts into 2# charging pile, uses
It charges in 2# charging pile.When more charging piles, by charge control queue priority, same operation.
Mode 5: the decline of one power demand of vehicle, vehicle two automatically obtain the power cut out
When the decline of vehicle a pair of power demand, charger discharges AC/DC charging module automatically.When 1# charging pile cuts out power,
By charge control queue priority, 2# charging pile obtains power automatically.
Mode 6: when vehicle is completed to charge, subsequent charge sequence shifts to an earlier date
When certain 1 trolley is completed to charge, affiliated charging pile automatically exits from charge control queue, and the charging pile of other startings exists
Position Forward in charge control queue, priority improve level-one.When the starting of other charging piles, it is automatically added to charge control team
The end of column possesses minimum priority.Default changes electric battery case charging and has highest priority, and priority is configurable.
Exchange is converted into direct current by AC/DC charging module by charger of the present invention；Charger output passes through switching control
Unit with change electric battery case or charging pile body connect；Monitoring device realizes charger output work by control switch control unit
Rate is in the switching changed between electric battery case or charging pile body.The present invention solves electrical changing station night power idle and charging station daytime
The high problem of vacancy rate, and solve the problems, such as more vehicles while charging, and when guaranteeing charging, it is carried out between charging pile effective
Power distribution, realize the efficient utilization of resource.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
It cans understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all to lead according to the present invention
The modification for wanting the Spirit Essence of technical solution to be done, should be covered by the protection scope of the present invention.
