Such as demand current reduction, then the busbar quantity that concentrator calculating can be exited, to match the current needs of reduction；Pass through concentration
The control of device disconnects the busbar coupling device prepared corresponding to the busbar exited, then the busbar exited and the charging attached troops to a unit
Unit reverts to freedom, and charging current is provided available for itself connected charging pile or other charging pile.
Now by taking Fig. 5, Fig. 6 a, Fig. 6 b, Fig. 7 a, Fig. 7 b as an example, which has 5 sections of busbares, 5 charging piles, specific to be situated between
It continues as follows：
All charging systems（Charging pile is stopped without vehicle and is charged）Idle, the charging gun of any charging pile can carry out at this time
30KW, 60KW, 90KW, 120KW, 150KW charge, if 1 demand of charging pile is 150KW：Then the first step, concentrator output after
Electric appliance ZHM1-3 is closed, and is closed intermediate relay KJ1, and then intermediate relay KJ1 is closed A.C. contactor KM1, so as to
To exchange turn DC Module UPR1/ UPR2 power supply, similarly, by be closed output relay ZHM1-4 ZHM1-5 ZHM1-6
ZHM1-7, make intermediate relay KJ2 KJ3 KJ4 KJ5 be closed, so as to make A.C. contactor KM2 KM3 KM4 KM5
It is closed, so as to turn DC Module UPR3-UPR10 power supplies to exchange；The output relay ZHM1-8 closures of second step, concentrator,
Make intermediate relay KL1 be closed, then intermediate relay KL1 make D.C. contactor KZ11 KZ12 be closed, similarly, pass through closure
Output relay ZHM1-9 ZHM1-10 ZHM1-11, make intermediate relay KL2 KL3 KL4 be closed, so as to connect direct current
Tentaculum KZ21 KZ22 KZ31 KZ32 KZ41 KZ42 all be closed, so as to charging pile 1 provide power 150KW,
Remaining charging pile can be only in subscription state, and charhing unit release to be had can just charge.
If 1 demand 60KW of charging pile, the first step, concentrator output relay ZHM1-3 4 be closed, make it is intermediate after
Electric appliance KJ1 KJ2 be closed, then intermediate relay KJ1 KJ2 make D.C. contactor KM1 KM2 be closed, so as to exchange turn
DC Module UPR1-UPR4 powers;The output relay ZHM1-8 closures of second step, concentrator, close intermediate relay KL1
Close, then intermediate relay KL1 make D.C. contactor KZ11 KZ12 be closed, so as to charging pile 1 provide power 60KW, remaining
3 charging piles（Charging pile 3,4,5）90KW can be freely distributed again.
If 3 demand 60KW of charging pile, can be closed D.C. contactor KZ21 KZ22 or D.C. contactor
KZ31 KZ32, control logic is same as above, if be closed D.C. contactor KZ11 KZ22, charging pile 1 can only export
30KW, the maximum exportable 60KW of charging pile 4/5；If be closed D.C. contactor KZ31 KZ32, charging pile 5 can only export
30KW。
If charging pile 2 can still be connected in the high-power 150KW chargings of progress, other stake with electric vehicle to be charged, and
Charging terminal（Substation：Charging pile end monitors）Reservation charging setting is carried out, when 2 demand power of charging pile reduces, such as be reduced to
60KW, then can discharge D.C. contactor KZ21 KZ22 KZ31 KZ32 KZ41 KZ42, remaining stake can charge.
The preferred embodiment exemplified below for dynamically distributing power：
The concentrator has reservation function, and the concentrator is required according to the reservation charging of the electric vehicle received and its charging work(
Rate information, the concentrator carry out dynamic allocation power, and the busbar coupling device of a few sections of busbares is controlled to be closed, makes this several sections of mothers
Line series connection is connected, and matches required charge power, and other than the connected charging pile of wherein one section of busbar is as reserved charging pile,
The charging terminal of the other charging piles of control makes these charging terminals control between the charging gun and busbar of the charging pile where it
Busbar coupling device disconnect；
And the charging pile for prompting the electric vehicle that other need to charge into the connected charging system of other busbares charges.
When the first charging pile carries out high-power charging to the first electric vehicle, several sections of busbares are occupied, lead to this several sections of busbares
On the charging pile of charging system attached troops to a unit can not currently charge；
Real-time demand charge information is informed concentrator by the charging terminal of the first charging pile and electric vehicle real-time communication, for
Concentrator is adjusted according to real time charging demand to the charging current value of the electric vehicle；
If at this moment having other electric vehicles to need, the second charging pile that can not currently charge at these charges simultaneously and charging gun is reliable
After connection,
According to the charging terminal of the first charging pile and electric vehicle real-time communication, such as demand current reduction, then concentrator calculating can move back
The busbar quantity gone out, to match the current needs of reduction；By the control of concentrator, the mother corresponding to the busbar exited will be prepared
Line coupling device disconnects, and after the connected busbar of the second charging pile is rejected, the busbar and the charhing unit attached troops to a unit revert to
Freely, the second charging pile starts charge function automatically.
Embodiment 2
Referring to Fig. 8,9.In the present embodiment, each section of busbar passes through mother respectively with remaining each section of busbar in each section of busbar
Wiring connector part connects, and forms looped network formula flexibility charging station.
In the present embodiment, all charhing units are idle, and the charging gun of any one charging terminal can carry out at this time
30KW, 60KW, 90KW, 120KW, 150KW charge.
If the charging gun demand of charging pile 1 is 150KW：Concentrator is opening all module and by the electricity of each bus section, busbar section
After pressure adjustment is consistent, according to certain principle or computational methods 4 groups of busbar connector group KZ121 KZ122 or KZ131
KZ132 or KZ141 KZ142 or KZ151 select in KZ152 one group with KZ231 KZ232 or KZ241 KZ242 or
KZ251 select in KZ252 one group with KZ341 KZ342 or KZ351 KZ352 select one group with KZ451 KZ452 it is same
When be closed, 5 sections of busbares are connected, meet the work requirements of the charging gun of charging pile 1.Remaining charging gun can be only at this time
Subscription state.It has treated charging subelement release, can just charge；When the charging gun charge power of charging pile 1 constantly reduces, then
From as far as closely disconnecting corresponding mother contactor successively.Such as：Be closed at be KZ121 KZ122, KZ241 KZ242,
KZ351 KZ352 and KZ451 KZ452, then can disconnect successively KZ351 KZ352, KZ451 KZ452, KZ241
KZ242、KZ121\ KZ122。
If the charging gun demand 90KW of charging pile 1, Centralized Controller is opening all module and by each bus section, busbar section
After voltage adjustment is consistent, according to certain principle or computational methods mother contactor group KZ121 KZ122 or KZ131
