Specific implementation mode
A kind of annular power as shown in Figure 1 shares intelligent charging machine, including multiple power being connected on three phase mains
Unit, for power cell three-phase alternating current is converted to direct current, the output end correspondence of each power cell connects that there are one fill
Electric terminals, for charging terminal to connect vehicle and charge for vehicle, the output end of each power cell passes through ring busbars
It is connected with charging terminal, then ring busbars are changed to integrate all power cell output powers by contactless contactor folding
Become single charging terminal and correspond to ring busbars length, realizes charging terminal output power real-time variable, be provided on ring busbars
The contactless contactor that adjacent power cell isolation is opened, charging terminal include current sampler, fuse, diode and control
The contactless contactor of charging terminal conducting.
For the utility model by taking four groups of power cells as an example, corresponding four charging terminals are respectively CDQ1-CDQ4, and annular is female
To contactless contactor that power cell one and power cell two is isolated it is KM1, KM2 on line, work(is isolated on ring busbars
The contactless contactor of rate unit two and power cell three is KM3, KM4, power cell three and power is isolated on ring busbars
The contactless contactor of unit four is KM5, KM6, the contactor of power cell four and power cell one is isolated on ring busbars
Switch is KM7, KM8, and corresponding contactless contactor is respectively KM9-KM12 on four charging terminal CDQ1-CDQ4.
A kind of annular power shares the charging method of intelligent charging machine, includes the following steps：
S1 is by charging terminal connecting electric automobile；
S2 judges that whether the charging terminal corresponds to power cell occupied, enters S3, if occupied if unoccupied
Then enter S5；
S3 judges whether corresponding power cell meets Vehicular charging demand, and charging terminal, which directly initiates, if meeting fills vehicle
Electricity enters S4 if being unsatisfactory for；
S4 judges whether there is vacant power cell, the preferential power cell for selecting adjacent stations, if having on ring busbars
Control switch vacant power cell is linked into ring busbars and corresponding power cell composition power cell group, described in cooperation
Charging terminal is that electric vehicle charges jointly；Charging terminal is informed if not, and records charge requirement；
Control on S5 ring busbars is switched exits the ring busbars to charge by occupied power cell；While into
Enter S3, when occupied power cell exits ring busbars, the charging terminal to charge actively can again be found newly
Idle power unit supplemented；
S6 after charging terminal charging complete, disconnects this charging terminal, according to the charge requirement recorded before, ring there are one
The corresponding power cell of the charging terminal is linked on ring busbars by the control switch on shape busbar, with the charging recorded before
The corresponding power cell of terminal collectively constitutes power cell group, is used for the charging terminal recorded before；When there is power cell group
Charge requirement reduce, then the power cell in addition to power cell corresponding with the charging terminal is exited into the power cell group,
Simultaneously by its power cell recomposition power cell group corresponding with the charging terminal recorded before, for the charging end recorded before
End uses.
The utility model is described further with reference to specific embodiment.
When terminal CDQ1 connection vehicles remaining charging terminals is idle, vehicle sends charge requirement to terminal control unit,
Terminal control unit judges whether this section of power cell one meets charge requirement（Contact-making switch under original state on ring busbars is equal
For off-state）, if satisfied, then directly charging, if being unable to meet demand power, pass through contactless contactor according to demand
KM1-KM8 is attracted the power cell quantity of selection access ring busbars, and allocation unit controls KM1-KM8 and is attracted power cell two
CDQ1 busbares are all thrown into power cell four, realize fast mend；If the vehicle of terminal CDQ2 connections at this time, terminal control unit will
KM1, KM2, KM3, KM4 are disconnected, and CDQ1 accounts for three power cells, and CDQ2 accounts for a power cell, if CDQ2 mono- is not enough；It will
CDQ1 corresponds to vehicle SOC（Battery）SOC corresponding with CDQ2 is compared, if | CDQ1 SOC-CDQ2 SOC | if≤20% by KM1,
KM2, KM5, KM6 disconnect CDQ1, CDQ2 and divide bus power equally；If | CDQ1 SOC-CDQ2 SOC | >=20%, CDQ1 correspond to SOC
It is relatively low, then by KM1, KM2, KM3, KM4 disconnect, CDQ1 distribute three power cells, CDQ2 distribute a power cell, it is on the contrary then
KM1, KM2, KM7, KM8 are disconnected, CDQ1 distributes a power cell, and CDQ2 distributes three power cells, when CDQ1 corresponds to vehicle
After charging complete, KM9 is disconnected, KM1-KM8 is all attracted all power cells if CDQ2 charge requirements are still very big
Switching disconnects KM10 to CDQ2, otherwise when CDQ2 corresponds to Vehicular charging after the completion of, as CDQ1 charge requirements still very greatly if general
All all power cell switchings of actuation are to CDQ1 by KM1-KM8, when connecting vehicle such as CDQ1, CDQ2, CDQ3, KM1, KM2,
KM3, KM4 are disconnected, and CDQ2 exports this terminal-pair and answers power, and CDQ1, which is corresponded to vehicle SOC vehicle SOCs corresponding with CDQ2, to be compared
Compared with, if CDQ1 correspond to SOC it is relatively low if KM7, KM8 are attracted CDQ4 are corresponded into power cell switching to CDQ1, it is on the contrary by KM5,
KM6 is attracted corresponds to power cell switching to CDQ3, such as CDQ1-CDQ4 wholes connection vehicle by CDQ4, then KM1-KM8 is all disconnected
It opens, each terminal uses itself bus power, realizes trickle charge.
