In an exemplary embodiment, when the total power required by the charging pile with a high priority is lower than the power limit, the charging policy according to the priority may be combined with the charging policy according to the charging period, so as to obtain the final required charging policy. The charging strategies with the priority are used for executing charging operation on the charging piles with the high priority.

In one embodiment, when the management module inside the main charging pile determines the charging policy, the content requirements of the signal data from the terminal device also need to be met.

In step S405, the plurality of charging piles execute a charging strategy.

In one embodiment, the charging policy may be received and executed by a plurality of charging posts that are performing a charging operation, and the charging policy may be received and executed by all of the charging posts.

In one embodiment, a plurality of charging piles that are performing charging operations other than the master charging pile may be noted as slave charging piles, which need to receive and execute charging policies. When the main charging pile is a charging pile which is in charging operation, the main charging pile needs to determine and send a charging strategy and also needs to receive and execute the charging strategy. When the main charging pile is a charging pile that does not perform charging operation, the main charging pile needs to determine and transmit a charging policy.

The communication module can send the charging pile working state information of the charging pile to the communication modules of other charging piles through communication connection. Meanwhile, the communication module of the charging pile also receives the charging pile working state information from other charging piles.

Step S503, selecting a main charging pile.

In one embodiment, the inter-pile ad hoc network may be performed, or the main charging pile may be selected from a plurality of charging piles performing the charging operation, or may be selected from all the charging piles, according to the charging pile operation state information of all the charging piles through communication connection. The main charging pile can be selected based on the number of the charging piles, the sequence of charging access, or random selection and other methods. And a plurality of standby main charging piles can be selected for completing the determination and the transmission of the charging strategy by taking the standby main charging piles as the main charging piles when the management module in the main charging piles fails and the determination and the transmission of the charging strategy cannot be performed, so that the charging operation is ensured.

Step S504, judging whether the affiliated charging pile is a main charging pile.

In one embodiment, after the primary charging post is determined, a signal is sent to the primary charging post, and the management module in the inner 5 portions of the charging post receives the signal to determine the charging strategy. If the charging pile receives the signal, judging the charging

If the pile is the main charging pile, the result is yes, and if the signal is not received, the result of judging whether the belonging charging pile is the main charging pile is no. By way of example, the management module inside the main charging pile can execute the work of determining the charging strategy by enabling the signal, and judge whether the charging pile is the main charging pile.

In step S505, the charging policy is determined and transmitted.

0 in one embodiment, this step is performed if the belonging charging stake belongs to the primary charging stake. According to the working state of the charging pile

And (5) information or a power limit value, and the main charging pile performs charging operation of the charging pile by determining a charging strategy. Under the requirement of meeting the power limit value, the management module inside the charging pile determines the charging strategy, and the optimal charging efficiency is realized.

In one embodiment, the charging strategies of embodiments of the present invention include, but are not limited to: according to the sequence of receiving the charging request

Sequentially, controlling the charging piles to perform charging operation; and controlling the corresponding charging piles to perform charging operation for 5 times in a preset time period; controlling each charging pile to charge based on the priority of each charging pile; based on each of the charges

The preset electric quantity of the piles controls each charging pile to alternately perform charging operation; a plurality of charging piles perform charging operation simultaneously; and alternately performing the charging operation based on the charging pile numbers of the plurality of charging piles performing the charging operation. The charging policy of the embodiment of the invention may be stored in advance in a management module disposed in the charging pile, and the method for determining the charging policy by the management module in the charging pile includes: selecting or combining from preset charging strategies.

Step S506, receiving and executing the charging policy.

In one embodiment, the master charging pile or the slave charging pile when the result of judging whether the slave charging pile is the master charging pile is no, wherein the slave charging pile refers to a plurality of charging piles which are not in charging operation and are in charging operation, the charging strategy is received through the communication module, and then the charging strategy is executed through the internal management module, or the charging strategy is received and executed directly through the communication module. The execution actions to execute the charging policy include start of charging, suspension of charging, end of charging, and the like.

Fig. 6 is a flowchart of a charging management method using process provided in an embodiment of the present application. As shown in fig. 6, when there is a standby

When the charging equipment is connected to the charging pile or the charging pile is used for completing charging operation, the method is executed, and the specific steps are as follows:

step S601, transmitting the charging pile operation state information of the charging pile.

In one embodiment, when the to-be-charged device with the charging requirement is connected to the charging pile, or the charging pile completes the charging operation

In operation, the management module inside the charging pile sends the charging pile working state information of the charging pile, and after receiving the charging pile working state information, the 0 management module inside the main charging pile updates the previous charging pile working state information based on the power limit

And determining the charging strategy by the value and the updated charging pile working state information of the plurality of charging piles. For example, when the equipment to be charged is connected to the charging piles, the number of charging piles being charged can be increased, the total power required by the charging piles can be increased, and the determination and the transmission of the charging strategy are required to be carried out again based on the existence of the power limit value; when the charging pile completes the charging operation, the charging pile is charged

The number of electric piles is reduced, residual power is generated based on the existence of the power limit value, and a charging strategy needs to be determined and executed again, 5, so that the utilization rate of available power of the residual power capacity of the power system is improved, and the efficiency of charging work is improved.

In one embodiment, when the device to be charged is connected to the charging pile, or when the charging pile completes the charging operation, it may be determined whether the primary charging pile needs to be selected again, so as to improve the charging efficiency. For example, when executing the charging strategy of alternately charging a plurality of charging piles, the charging piles can be changed into the charging piles with the latter charging piles as the main charging piles, so that the charging piles can be prevented from being required to be confirmed

Two kinds of work of charging strategies are fixed and executed, so that the work efficiency is reduced; when the charging strategy of charging according to the priority is executed, the charging pile with low priority can be changed into the charging pile with low priority as the main charging pile, so that the charging efficiency is improved.

In one embodiment, the charging pile operation state information of the charging pile may be sent through an inter-pile ad hoc network or a communication connection. The ad hoc network component of the communication module of the charging pile or all charging piles being charged is always in an on state, such as a bluetooth component and a wireless network component, and when the charging equipment to be charged is connected to the charging pile, the ad hoc network component of the communication module receives the charging pile working state information of the newly connected charging pile, updates the charging pile working state information to the charging pile working state information of the charging piles being charged, and further determines the charging strategy again. In order to save electric quantity, the self-networking component of the communication module of the main charging pile is always in an on state, and the management modules in the rest charging piles are only started when the self-networking component of the communication module of the main charging pile sends data signals. The ad hoc network components of the communication modules of all the charging piles can be always in a closed state, and when data are required to be sent and received, or when the communication module of the main charging pile receives the charging pile working state information of the newly-accessed charging pile, a starting signal is sent to the communication modules of the rest charging piles through the internal management module of the main charging pile, so that the ad hoc network components of the communication modules of the rest charging piles are started.

Step S602, the charging policy is redetermined and sent.

In one embodiment, the management module controlling the interior of the primary charging peg re-determines the charging policy and the communication module controlling the primary charging peg re-transmits the charging policy.

In one embodiment, to increase the charging efficiency, increase the utilization of the available power of the remaining power of the power system, and increase the user experience, a determination of the charging strategy needs to be made anew.

In one embodiment, when a device to be charged is connected to the charging post, the total power of the charging post being charged is further increased, and the possibility of exceeding the power limit exists. Firstly, the charging pile working state information of the newly accessed charging pile, such as priority and the like, is judged. And secondly, updating the charging pile working state information of the charging pile which is being charged based on the judging result. And finally, re-determining and adjusting the charging strategy based on the updated charging pile working state information of the charging pile which is being charged. The charging policy according to the priority may be combined with a charging policy according to charging in a preset period of time, so as to obtain a final charging policy. Exemplary, wherein the prioritized charging policy is used to perform a charging job on a charging pile with a high priority; and the charging strategy for charging according to the preset time period is used for executing the charging strategy by the charging pile with low priority within the limit of the residual power after the charging strategy with priority is executed.

In one embodiment, when the charging pile completes the charging operation, the remaining power is generated, so that the charging pile operating state information of the charging pile being charged needs to be updated in time, and the charging efficiency is improved. When the charging pile completes the charging operation, the total power of the charging pile which is in charging is lower than the power limit value, the charging pile working state information of the charging pile which is in charging is updated, and the charging strategy of charging according to the preset electric quantity is changed into the charging strategy of directly charging a plurality of charging piles at the same time.

In one embodiment, the charging piles being charged may be re-inter-pile ad hoc for transmitting the charging policy. When the equipment to be charged is connected to the charging pile, or when the charging pile finishes the charging operation, the inter-pile ad hoc network needs to be re-performed due to the change of the charging pile working state information which is in charge, including the number of charging piles in charge and the change of the power used by the charging piles, so as to send a new charging strategy.

In step S603, the charging strategy is received and executed again.

In one embodiment, when a device to be charged is connected to a charging pile, or when the charging pile completes a charging operation, the charging pile which is being charged receives and executes the charging policy again based on the updated charging policy.

In one embodiment, after receiving the charging policy again, the charging stake for executing the charging policy may execute the charging policy again after executing the charging operation to the preset charging stake or after executing the charging operation to the preset charging stake for a preset time or for a preset amount of electricity. After the charging pile that is charging is receiving the charging policy again, the re-received charging policy may be directly executed.

In the embodiment of the invention, when the charging pile which is in charging executes the re-received charging strategy, if the equipment to be charged is connected to the charging pile, or when the condition that the charging pile completes the charging operation occurs, the method is executed again.
