The core of this application is to provide a charging station control and management equipment, which can prevent the charging station from being overloaded and avoid adverse effects on the voltage and power of the distribution network; another core of this application is to provide a charging station. It also has the above-mentioned technical effect.

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a charging station control management device provided by an embodiment of the present application; referring to FIG. 1, the charging station control management device may include: a first communication component 10, a second communication Component 20, and processor 30;

Specifically, the first communication component 10 is mainly used for performing data communication with each charging pile, receiving operating parameters such as charging power of each charging pile and charging request, and further transmitting the received charging power of each charging pile to the processor 30. Provide a basis for subsequent analysis and judgment by the processor 30. Among them, the first communication component 10 can perform data transmission with the charging pile through wired communication, or can also realize data receiving and sending through wireless communication, that is, the first communication component 10 can be a wired communication component, for example, RS232 Components, CAN components, etc.; can also be wireless communication components, for example, WIFI components, ZigBee components, LOAR components, etc. In this regard, the present application does not make a unique limitation, and the details may be determined according to actual conditions. In addition, combined with actual needs, the charging station control management equipment can also be equipped with wired communication components and wireless communication components at the same time to meet the needs of different communication methods in practical applications.

The second communication component 20 is responsible for data communication with the system platform server, and receiving the power capacity of the current charging station sent by the system platform server. The so-called power capacity refers to the maximum allowable charging power value of the current charging station. Wherein, the power capacity can be adjusted according to factors such as charging period and charging area to meet actual needs. After receiving the current power capacity of the charging station, the second communication component 20 also transmits it to the processor 30 to provide a basis for the processor 30 to analyze and judge. In addition, the second communication component 20 can also report the relevant situation of the current charging station to the system platform server, for example, report the number of idle charging piles and queuing status of the current charging station to the system platform server, so as to facilitate users and management personnel to know The current operating status of the charging station. Wherein, the application also does not make a unique limitation on the specific type of the second communication component 20 , and it can be set differently according to the actual situation. For example, the second communication component 20 may specifically be a 4G communication component, an Ethernet component, and the like.

The processor 30 is responsible for judging whether the current charging station has a power reserve according to the power capacity of the current charging station and the charging power of each charging pile after receiving the charging request, that is, judging whether the corresponding charging pile can be allowed to charge the current electric vehicle without exceeding the power capacity of the current charging station. Among them, the way for the processor 30 to judge whether the current charging station has a power margin can be: sum the charging power of each charging pile to obtain the total charging power; calculate the total charging power of each charging pile and the power capacity of the current charging station. Difference; determine whether the difference is less than the requested power of the charging user, if less, then the current charging station has no power margin. Otherwise, the current charging station has a power reserve. If the current charging station has a power reserve, the processor 30 immediately responds to the charging request, and sends a control command to allow charging to the corresponding charging pile via the first communication component 10; on the contrary, if the current charging station has no power reserve, then process The device 30 can adjust the charging power of the charging pile. Specifically, if the current charging station has no power margin, the charging station control management device can immediately respond to the charging request of the electric vehicle, but at the same time it will adjust the charging power of the charging pile so that the charging pile can adjust The final charging power is used to charge the electric vehicle, so that the total charging power does not exceed the power capacity of the current charging station.

Among them, the charging station control management equipment can only adjust the charging power of the current charging pile, that is, the charging pile that sends the charging request; or the charging station control management equipment can also adjust the charging power of each charging pile, so that each charging pile can be adjusted The final charging power is used for charging.

Further, in the case of adjusting the charging power of each charging pile, under the condition that the power capacity of the charging station is not exceeded, the charging power of each charging pile can be adjusted by means of equal distribution, that is, the adjusted charging power of each charging pile The charging power is equal; or the charging power of each charging pile can also be adjusted through unequal distribution, that is, the adjusted charging power of each charging pile is not equal. For the specific adjustment method, the present invention does not make a unique limitation, and different settings can be made according to actual conditions.

Or, if the current charging station has no power margin, the response to the charging request of the electric vehicle is delayed, that is, the station control management device of the charging station will not immediately respond to the charging request of the electric vehicle, but needs to wait until the current charging station has a power margin again. For example, the charging request is only responded to when other electric vehicles finish charging.

Optionally, the processor 30 is specifically configured to: if the current charging station has no power margin, write the current electric vehicle into the queuing list; when the current charging station has a power reserve, query the queuing list of the current electric vehicle from the queuing list order and respond to charging requests according to the queuing order.

Specifically, in this embodiment, the processor 30 performs charging control by waiting in a queue. Specifically, when the processor 30 receives a charging request and judges that the current charging station has no power reserve, it writes the current electric vehicle into the queuing list, so that the corresponding charging pile is in a state of waiting for charging, during which the processor 30 polls each charging pile to know whether there is a charging pile that has finished charging, that is, to know whether the current charging station has a power reserve again. When the current charging station has a power reserve again, the processor 30 can query the current queuing sequence of the electric vehicle from the queuing list, and respond to the charging request according to the queuing sequence. For example, when it is known that an electric vehicle finishes charging, if the current electric vehicle ranks first, the processor 30 can immediately respond to the charging request of the current electric vehicle; position, the processor 30 immediately responds to the charging request of the first-ranked electric vehicle, and the current electric vehicle continues to wait. Wherein, the above-mentioned queuing order may be based on the order in which the charging requests are received, that is, "first come, first charged"; or it may also be based on the price preference of the charging station, for example, prioritizing the charging of electric vehicles. The period of preferential price; or it can also be sorted according to the credit rating of users. Of course, in combination with the actual situation, the above factors can also be combined for sorting or other sorting methods can be used, which can be determined according to actual needs.

In addition, the present application also does not limit the specific type of the processor 30, for example, it may be a Cortex A7 processor.

To sum up, the charging station control management equipment provided by this application can control the charging power of the charging station within the allowable range by controlling whether the charging pile is working or not, so as to prevent the occurrence of overloading and avoid damage to power distribution.
