Device is sorted from large to small according to maximum redundancy load, obtains the queue of redundancy load；
It will be distributed into charge requirement queue near preceding charger near preceding distribution transformer in redundancy load queue；
When distribution transformer forward in charge requirement queue, which has reached, accommodates the upper limit, then distribute to the charge requirement team of latter position
The distribution transformer of column, until charger is assigned in the end in charge requirement queue；
After charger in redundancy load queue is assigned every time, next charger is required to attempt distribution to charge requirement
In the forward distribution transformer of queue, distribution is successively attempted backward if it can not accommodate；
If there is any charger that can not distribute suitable distribution transformer, by flexible heap cooperation of charging, charge requirement is reduced
Total value repeats the above steps, until all chargers complete grouping.
