It should be noted that, if the total pre-charging power at the current time is less than the remaining available electric power, the charging requirements of all the subscribed users in the priority sequence at the current time can be met. And if the total pre-required charging power at the current time is greater than the remaining available electric power, the charging requirements of the reservation users with high priorities in the priority sequence at the current time are met preferentially, and the reservation users with low priorities are pushed to the next time and the total pre-required charging power at the next time is calculated. Through the mode, the intelligent charging distribution processing is realized, the charging and using requirements of the reservation users who need to use the electric automobile urgently are preferentially met, and the electric automobile of the reservation users who need not use the electric automobile urgently can be charged.

s402, when the judgment result is yes, arranging the corresponding reservation users into a first priority sequence according to the sequence of the reservation time;
s403, when the judgment result is no, arranging the corresponding reservation users into a second priority sequence according to the sequence of the reservation time;
s404, the reservation users in the first priority sequence are charged in the reservation users in the second priority sequence preferentially.

Through the mode, the reservation users who urgently need to use the new energy vehicle or the electric vehicle are respectively arranged, so that the charging and using requirements of the reservation users who urgently need to use the electric vehicle are met under the condition that the electricity consumption peak time of residents or the residual available electric power is small; under the condition that residents are in non-electricity utilization peak periods or the residual available electric power is large, the charging and using requirements of reservation users who do not need to use the electric automobile urgently are met, and therefore charging or using processing of the reservation users who meet different charging requirements or automobile using requirements is met.
Preferably, in this embodiment, the preset emergency degree is level 3, and the highest charging emergency degree is level 5; the charging urgency degree is expressed as the electric automobile which needs to be charged according to the charging waiting time after the reservation time of the reservation user; the higher the level of the charging delay degree is, the shorter the waiting time of the reservation user in the charging waiting time is. Specifically, the charging wait time of the reservation user is greater than the charging time of its charge amount demand, and the charging wait time includes the charging time of the charge amount demand and the additional wait time. In this embodiment, the minimum value of the extra waiting time is half an hour, and in other embodiments, the minimum value of the extra waiting time may be limited according to actual requirements.

s802, judging whether the residual available electric power is still electric power residual;
s803, when yes, the remaining available electric power is distributed to the reservation user with high priority in the second priority sequence of the current time:
s804, automatically arranging the reservation users with low priority in the second priority sequence of the current time to the next time and calculating the total pre-charging power in the next time.
It should be noted that, if the total pre-charging power at the current time is greater than the remaining available electric power, the charging requirement of the reservation user in the first priority sequence at the current time is preferentially met, so as to meet the charging and using requirement of the reservation user who needs to use the electric vehicle urgently. If the electric power is still left, the left available electric power is distributed to the reservation users with high priority in the second priority sequence; and the reservation users with low priority in the second priority sequence automatically arrange to the next time and calculate the total pre-charging power in the next time. Through the method, the intelligent charging distribution processing is realized, the charging and using requirements of reservation users who urgently need to use the electric automobile are preferentially met, and the electric automobile of the reservation users who do not urgently need to use the electric automobile can be charged under the condition that the remaining available electric power is also remained; the reservation users with low priority in the second priority sequence are automatically arranged in the next time and the total pre-required charging power in the next time is calculated, so that the charging sequence of the reservation users is charged according to the priority sequence, the charging and using rationality or the humanization degree is improved, and the charging or using treatment of the reservation users with different charging requirements or vehicle using requirements is met.
In addition, because the proportion of users who urgently need to use the electric automobile is small, the charging processing of the reservation users in the first priority sequence of the current time can be satisfied under normal conditions. If the remaining available electric power at some time is less than the pre-required charging power of the reservation users in the first priority sequence, the reservation users with high priority in the first priority sequence carry out charging processing, the reservation users with low priority in the first priority sequence at the current time automatically arrange to the next time and calculate the total pre-required charging power in the next time, so that the charging processing of the reservation users is carried out according to the charging sequence of the priority, and the charging and use rationality or humanization degree is improved.
Through the charging distribution mode, the intelligent distribution of the residual available electric power of the power supply equipment can be realized in real time under the condition that the capacity increase of a power grid and the power supply equipment is not needed, the loads of the power grid and the power supply equipment cannot be exceeded in the peak electricity utilization period or the non-peak electricity utilization period of residents, the safety of the power grid and the power supply equipment is guaranteed, the intelligent use efficiency of the intelligent charging pile is improved under the condition that the electricity utilization of residents is normal, the charging and the normal use of electric automobiles of users are guaranteed, and the electric vehicle charging distribution mode has the effect of promoting the popularization and the popularization of electric vehicles.
