5. the charging pile that multiple gun automated power as claimed in claim 3 is distributed, it is characterised in that：At least five power module work(
The outlet line of DC+, DC- of the output of rate packet forms a matrix form relay connection end point, matrix form relay respectively
It is attached using nonpolarity matrix form relay group and cable between connection end point.
6. the charging pile that multiple gun automated power as claimed in claim 5 is distributed, it is characterised in that：Matrix form HVDC relay
HVDC relay group between device connection end point constitutes nonpolarity matrix form relay group, and every group includes two HVDCs
Relay, controls the break-make of DC+ and DC- respectively.
7. the charging pile that multiple gun automated power as claimed in claim 3 is distributed, it is characterised in that：Also include a direct-current charging post
Control module, direct-current charging post control module connects the shared packet pond of power module by CAN, and by switching control nothing
The closed and disconnected of Polarity Matrix formula relay group, reaches power module power and is grouped the power for exporting to different DC chargings
Rifle.
8. the charging pile that the multiple gun automated power as described in claim 1 to 7 any one is distributed, it is characterised in that：To charging
Multiple power modules of stake are grouped, the common busbar of the power module in the packet of each power module power, each power module
Power packet independently forms the output of DC+, DC-；Busbar is not total between the packet of each power module power.
9. the implementation method of the charging pile of a kind of multiple gun automated power distribution, it is characterised in that：Specifically include following steps：
1) start：Current charging pile is just being connected with electric automobile and is being charged；
2) direct-current charging post control module detects the power P WA that the automobile connected on DC charging rifle i needs；
3) whether power module power packet i just externally charges in power output：If it is not, turning the 7th step；If it is, going down
One step.
4) with the presence or absence of idle power module power packet in direct-current charging post control module detecting system, if there is no sky
Not busy power module power packet, then temporarily do not need to charge to being connected with automobile on DC charging rifle i, has waited power module work(
Rate packet is recharged when idle, terminates this charging dispatching algorithm；It is grouped if there is idle power module power, is walked next
Step.
5) power module power packet i and the common busbars of current and power module power packet i external power output together are stopped
All power module power be grouped external power output；
6) the power module power packet of free time is replaced power module power packet i, and recover the 5) stop it is external
Power output；Can so cause that power module power is grouped i idle；
7) the peak power Power that can be provided is grouped by the way that PWA is divided exactly power module power, the numerical value for obtaining is exactly except electricity
Source module power packet i it is outer, it is necessary to power module power packet count Groups.
8) in addition to power module power packet i, cyclic query to Groups idle power module power packet, and power supply mould
Block power packet i prepares external power output and is charged to automobile together；If the power module power packet of all current idles
Less than Groups, then all of idle module and power module power packet i prepare external power output to automobile to number together
Charge.Control prepares between the power module power packet of external power output and matrix form relay connection end point i together
Nonpolarity matrix form relay group, forms the charging to the automobile connected on DC charging rifle i.
9) direct-current charging post control module controls each power module power to be grouped and gives automobile charging.
