when the load quantity output in the field charging pile orderly output load quantity strategy is smaller than the actual available load quantity, a charging instruction is issued to the field alternating current/direct current charging pile;
and when the load quantity output in the field charging pile orderly output load quantity strategy is larger than the actual available load quantity, a delayed charging instruction is sent to the field alternating current/direct current charging pile.
8. The ordered charging method according to claim 7, wherein the remote monitoring platform issues a charging command to the site ac/dc charging pile according to the load amount output in the site charging pile ordered output load amount policy and the actual available load amount, and further comprising:
and when the load quantity output by the remote monitoring platform according to the field charging pile ordered load quantity output strategy is larger than the actual available load quantity, a power-reducing charging instruction is sent to the field alternating current/direct current charging pile.
9. The ordered charging method of claim 8, wherein the in-situ ordered charging control module comprises an alternating current ordered charging control unit and a direct current ordered charging control unit;
the field ordered charging control module formulates a strategy for controlling the field charging pile to output the load quantity in order according to the demand instruction; and will the on-the-spot electric pile ordered output load volume strategy of filling is passed back to remote monitoring platform includes:
the alternating current ordered charging control unit formulates a field alternating current charging pile ordered output load quantity strategy according to a demand instruction; and the on-site alternating current charging pile orderly output load quantity strategy is transmitted back to the remote monitoring platform; and the direct current ordered charging control unit formulates an ordered output load capacity strategy of the on-site direct current charging pile according to a demand instruction, and transmits the ordered output load capacity strategy of the on-site direct current charging pile back to the remote monitoring platform.
10. The ordered charging method of claim 6, further comprising:
when the remote monitoring platform is offline, the field ordered charging control module directly receives a demand instruction of a user, and a field charging pile ordered output load strategy is formulated according to the demand instruction;
the field ordered charging control module acquires the actual available load of the transformer in the transformer area;
and the field ordered charging control module issues a charging instruction to the field alternating current/direct current charging pile according to the load quantity output in the field charging pile ordered output load quantity strategy and the actual available load quantity.
