Source module, the sub- power module is defined as acquiescence ownership module；
Step 3, the state and access times of each sub- power module of system dynamic access, certain sub- power module state from sky
When not busy state is to working condition, the access times of the sub- power module add 1, certain sub- power module state from working condition
During to idle condition, the access times of the sub- power module are constant, and system is corresponding by charging gun when charging gun is stopped
Acquiescence ownership module according to the access times of sub- power module number resequenced；
Step 4, the aggregate demand that system passes through the access times of purple Yunnan source module, the state of each sub- power module and charging gun demand
Module number carries out dynamically distributes to sub- power module.
As a kind of preferred scheme, step 2 is specially：
Sub-step 1, system closes all electrical contact switches of all sub- power modules, closure；
Sub-step 2, system obtains the VD of each charging gun, defeated in the direct current of the VD of all charging guns
Go out voltage for 0 when, start each sub- power module successively by list of physical addresses；
Sub-step 3, after a sub- power module is started, system obtains the VD of current each charging gun, if a certain
More than the threshold value set, then the charging gun can export filling for energy to the VD of individual charging gun as the sub- power module
Electric rifle；
Sub-step 4, is switched off to contactor successively according to contactless contactor list, after the disconnection of each contactless contactor, is
System obtains the charging gun rifle number that charging gun VD is reduced to 0 from threshold value, if only one has direct current output charging gun
When voltage, this sub- power module is defined as the acquiescence ownership module of this charging gun.
As a kind of preferred scheme, step 4 is specially, when a charging pile obtains a use demand, to be needed after system section
Electric current and the every greatest requirements galvanometer of sub- power module under current demand voltage is asked to calculate aggregate demand module number, then
The acquiescence that system is resequenced according to one-level belongs to module, and sub- power module is carried out to use distribution.
The beneficial effects of the invention are as follows：
1. solving the dependence of a many sub- electric circuits of electric power source pair of module, reduce the maintenance of direct-current charging post and make
With the workload of operation；
2. rational be allocated management to each sub- power module, optimize the access times of each sub- power module, make each sub- power supply
The utilization rate of module is tried one's best average.

Wherein：1st, power module control unit, 2, pile body control unit, the 3, first charging gun, the 4, second charging gun.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples.
Embodiment：The electric circuit topology diagram of a kind of charging pile, as shown in figure 1, being arrived including 6 sub- power module M1
M6,3 contactor K1 to K3, power module control unit control 6 sub- power modules and 3 contactors, pile body control unit
Acquisition of information is carried out to the first charging gun direct current sampling S1, pile body control unit enters row information to the second charging gun direct current sampling S2
Obtain.
Multi-power module address acquisition and homogeneous state control method based on address state table, comprise the following steps：
Step 1,1 ╳ 6 sub- power module address list, access times count table, current operating state table are set up；6 ╳ 2 rifle
Number-contactor corresponding table, acquiescence rifle number ownership table, wherein 2 module's address lists are the address of 6 sub- power modules, using secondary
Counting number table is current module status for opening times, the current operating state table of sub- power module corresponding with address list
（Offline, idle, work）, contactor corresponding table be the every corresponding contactor sequence number rifle of each submodule correspondence, acquiescence rifle number
Belong to the rifle that table is sub- power module acquiescence ownership other.
Step 2, electricity is received after address acquisition instruction on charging pile, and power module control unit is led to each sub- power module
News, obtain the address of each sub- power module, the sequencing for putting in order to get；
Step 3, each sub- power module, closure contactor K1, K2, K3 are closed；
Step 4, S1, S2 sampled signal are obtained by pile body control unit, if also there is DC voltage, each son is just again switched off
Power module, untill at least no longer there is DC voltage,；
Step 5, the minimum sub- power module of the sequence number of opening module address list（Serial number n）, obtained by pile body control unit
Take S1, S2 sampled result；
Step 6, K1 is disconnected, then S1, S2 sampled result are obtained by pile body control unit, if S1 has voltage, S2 no-voltages,
K1 is write in the position of relay list in the 1st element of contactor corresponding table；If S2 has voltage, S1 no-voltages,
2nd element of contactor corresponding table writes K1 in the position of relay list；Skipped if S2, S1 have voltage；If
The equal no-voltage of S1, S2, and K1 disconnect before, S1 has voltage, then regulation cause its address sub- power module address list compared with
Small ordinal position, and in acquiescence rifle number ownership table relevant position write-in 1；If before K1 disconnects, S2 has voltage, then regulation causes its ground
Location sub- power module address list larger ordinal position, and in acquiescence rifle number ownership table relevant position write-in 2；
Step 7, K2 and K3 is disconnected successively, according to carrying out retest the step of step 6；
Step 8, the sub- power module opened is closed, 14 obtain S1, S2 sampled signal by pile body control unit, if also existing
DC voltage, is just again switched off each sub- power module, untill at least no longer there is DC voltage；
Step 9, repeat step 7 arrives step 8, until module all in address list has all been tested, by 6 ╳ 2 rifle number ---
In contactor corresponding table deposit memory；
Step 10, system is in normal communication, judges whether each sub- power module returns to its state, and the state returned whether
Normally, the status list of each sub- power module is determined, started once receiving after charging instruction, according to loading demand voltage, negative
Carry demand current to calculate the number of modules for needing to open, then come opening module successively, and judge module according to address list
The corresponding rifle number of the rifle number to be opened --- whether the row of contactor have value, if so, just bringing up to desired value in module voltage
Afterwards, rifle number --- the corresponding contactor in contactor is closed, will be right when the module of relevant position is opened in module's address list
The value of the access times count table of position is answered plus 1, when charging gun charging complete stops, by current module's address list, rifle
Number-contactor corresponding table rearranges according to access times count table, arrangement is according to being：To be to treat in acquiescence rifle ownership table
Stop module's address list corresponding to the sub- power module of charging gun number, rifle number-contactor corresponding table, used according to corresponding
Counting how many times table, is rearranged, and be stored in memory with the order counted from small to large.
When being again started up charging instruction, according to module's address list, the rifle number-contactor corresponding table for rearranging completion
To carry out module assignment and operation, repeat step 10.
