BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a flowchart of the steps of a centralized electric vehicle integrated energy supply method according to an embodiment of the present invention;

[0014] Figure 2 This is a structural diagram of a centralized electric vehicle integrated energy supply terminal according to an embodiment of the present invention. DETAILED DESCRIPTION

[0015] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0016] Please refer to Figure 1 , a centralized electric vehicle integrated energy supply method, comprising the steps of:

[0017] Obtaining electrical energy from the power storage device of the charging pile in the charging field;

[0018] If the utilization rate of the charging field is in a full state greater than or equal to a second preset value, and the power of the power storage device of the charging pile is lower than the first preset value, the power of the current charging vehicle corresponding to the charging pile is obtained, and the charging rate of the charging pile is adjusted according to the power of the current charging vehicle.

[0019] From the above description, it can be seen that the beneficial effects of the present invention are: obtaining the electric energy of the storage device of the charging pile in the charging field; if the charging field is in a full state and the electric energy of the storage device of the charging pile is lower than a first preset value, then obtaining the electric energy of the current charging vehicle corresponding to the charging pile, and adjusting the charging rate of the charging pile according to the electric energy of the current charging vehicle; thereby, the charging rate can be adjusted in real time according to the usage status of the charging field, the electric energy of the storage device of the charging pile and the electric energy of the current charging vehicle; when there are many charging vehicles and insufficient electric energy, the energy supply of low-power vehicles is guaranteed, thereby improving the efficiency of energy supply.

[0020] Furthermore, it also includes:

[0021] Obtaining the number of charging zones currently in use within the charging station;

[0022] It is determined whether the number of the charging intervals in use is less than a second preset value. If so, it is determined that the charging field is in a normal state; if not, it is determined that the charging field is in a full state.

[0023] As can be seen from the above description, judging the usage status of the charging field by the number of charging intervals in use in the charging field is simple and effective, so as to subsequently determine whether the charging rate needs to be adjusted.

[0024] Furthermore, adjusting the charging rate of the charging pile according to the current power level of the charging vehicle includes:

[0025] Determine whether the power level of the currently charging vehicle is less than or equal to a third preset value. If so, control the charging pile to charge the currently charging vehicle at a normal charging rate. If not, reduce the normal charging rate to obtain a reduced charging rate, and control the charging pile to charge the currently charging vehicle at the reduced charging rate.

[0026] From the above description, it can be seen that when the current charging vehicle's power is less than or equal to the third preset value, it means that the vehicle's power is too low. At this time, there is no need to reduce the charging rate. When the current charging vehicle's power is greater than the third preset value, the reduced charging rate is used for charging, ensuring that low-power vehicles can use electricity first, thereby improving the efficiency of energy supply.

[0027] Furthermore, reducing the normal charging rate to obtain a reduced charging rate includes:

[0028] The normal charging rate is reduced according to a preset range to obtain a reduced charging rate.

[0029] As can be seen from the above description, the normal charging rate can be reduced according to the preset range and can be reduced according to actual conditions, which is more flexible.

[0030] Furthermore, it also includes:

[0031] It is determined whether there is a charging interval in the charging field that is fully parked with charging vehicles. If so, a no-entry message is output in the charging interval that is fully parked with charging vehicles.

[0032] As can be seen from the above description, when the charging interval is full of charging vehicles, a no-entry message is output, and the vehicle can enter the next idle charging interval for charging, ensuring the rotation of the charging intervals, avoiding excessive wear and tear on a single charging interval, and ensuring that the storage devices of the charging piles in the charging intervals are always in a high energy state.

[0033] Please refer to Figure 2A centralized electric vehicle integrated energy supply terminal includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the following steps are implemented:

[0034] Obtaining electrical energy from the power storage device of the charging pile in the charging field;

[0035] If the utilization rate of the charging field is in a full state greater than or equal to a second preset value, and the power of the power storage device of the charging pile is lower than the first preset value, the power of the current charging vehicle corresponding to the charging pile is obtained, and the charging rate of the charging pile is adjusted according to the power of the current charging vehicle.

[0036] From the above description, it can be seen that the beneficial effects of the present invention are: obtaining the electric energy of the storage device of the charging pile in the charging field; if the charging field is in a full state and the electric energy of the storage device of the charging pile is lower than a first preset value, then obtaining the electric energy of the current charging vehicle corresponding to the charging pile, and adjusting the charging rate of the charging pile according to the electric energy of the current charging vehicle; thereby, the charging rate can be adjusted in real time according to the usage status of the charging field, the electric energy of the storage device of the charging pile and the electric energy of the current charging vehicle; when there are many charging vehicles and insufficient electric energy, the energy supply of low-power vehicles is guaranteed, thereby improving the efficiency of energy supply.

[0037] Furthermore, it also includes:

[0038] Obtaining the number of charging zones currently in use within the charging station;

[0039] It is determined whether the number of the charging intervals in use is less than a second preset value. If so, it is determined that the charging field is in a normal state; if not, it is determined that the charging field is in a full state.

[0040] As can be seen from the above description, judging the usage status of the charging field by the number of charging intervals in use in the charging field is simple and effective, so as to subsequently determine whether the charging rate needs to be adjusted.

[0041] Furthermore, adjusting the charging rate of the charging pile according to the current power level of the charging vehicle includes:

[0042] Determine whether the power level of the currently charging vehicle is less than or equal to a third preset value. If so, control the charging pile to charge the currently charging vehicle at a normal charging rate. If not, reduce the normal charging rate to obtain a reduced charging rate, and control the charging pile to charge the currently charging vehicle at the reduced charging rate.

[0043] From the above description, it can be seen that when the current charging vehicle's power is less than or equal to the third preset value, it means that the vehicle's power is too low. At this time, there is no need to reduce the charging rate. When the current charging vehicle's power is greater than the third preset value, the reduced charging rate is used for charging, ensuring that low-power vehicles can use electricity first, thereby improving the efficiency of energy supply.

[0044] Furthermore, reducing the normal charging rate to obtain a reduced charging rate includes:

[0045] The normal charging rate is reduced according to a preset range to obtain a reduced charging rate.

[0046] As can be seen from the above description, the normal charging rate can be reduced according to the preset range and can be reduced according to actual conditions, which is more flexible.

[0047] Furthermore, it also includes:

[0048] It is determined whether there is a charging interval in the charging field that is fully parked with charging vehicles. If so, a no-entry message is output in the charging interval that is fully parked with charging vehicles.

[0049] As can be seen from the above description, when the charging interval is full of charging vehicles, a no-entry message is output, and the vehicle can enter the next idle charging interval for charging, ensuring the rotation of the charging intervals, avoiding excessive wear and tear on a single charging interval, and ensuring that the storage devices of the charging piles in the charging intervals are always in a high energy state.

[0061] Wherein, adjusting the charging rate of the charging pile according to the current power level of the charging vehicle includes:

If so, control the charging pile to charge the currently charging vehicle at a normal charging rate.

If the charging field is full and the electric energy of the storage device of the charging pile is lower than the first preset value, the electric energy of the current charging vehicle corresponding to the charging pile is obtained, and the charging rate of the charging pile is adjusted according to the electric energy of the current charging vehicle. In this way, the charging rate can be adjusted in real time according to the usage status of the charging field, the electric energy of the storage device of the charging pile and the electric energy of the current charging vehicle. When there are many charging vehicles and the electric energy is insufficient, the energy supply of the low-power vehicle is guaranteed, thereby improving the efficiency of energy supply; when the electric energy of the current charging vehicle is less than or equal to the third preset value, it means that the vehicle's electric energy is too low, and there is no need to reduce the charging rate at this time. When the electric energy of the current charging vehicle is greater than the third preset value, the reduced charging rate is used for charging, ensuring that the low-power vehicle can use electric energy first, thereby improving the efficiency of energy supply; and the normal charging rate is reduced according to the preset range, and can be reduced according to actual conditions, which is more flexible.
