Description

Technical Field

[0001] The present invention relates to the technical field of charging power distribution, and in particular to a charging pile power distribution system. Background Art

[0002] With the booming global new energy vehicle industry, the electric vehicle market has gradually occupied a pivotal position. The rapid expansion of this market has led to a surge in demand for charging piles, which are a core component of its infrastructure. Charging piles, as an indispensable charging equipment for electric vehicles, have become an indispensable part of people's daily lives with their wide market coverage and efficient and convenient charging solutions. The continuous increase in the number of charging piles has effectively alleviated the charging problems faced by the public and further promoted the popularization and application of electric vehicles.

[0003] At the same time, electric vehicles have not only achieved rapid growth in number, but also become increasingly diverse in types and performance. In particular, the charging power of electric vehicles has been continuously improved, and the required voltage has also risen accordingly. In order to cope with this diversified trend, charging piles need to have a high degree of compatibility and be able to flexibly meet the charging needs of various types of electric vehicles in different scenarios. In the market, various types of electric vehicles with different charging powers have emerged, and to match them, the charging pile market has also presented a variety of charging power options. Against this background, multi-gun charging technology came into being. This technology has attracted widespread attention due to its advantages such as small footprint, low manufacturing cost and high resource utilization. However, despite the significant technical progress of multi-gun charging, there is still room for improvement in the energy distribution between the charging gun head and the power module.

[0004] Specifically, although there are many types of charging piles on the market, low-power electric vehicles still dominate the market. This will pose a challenge to the power distribution of charging piles, resulting in electric vehicles with high power requirements being unable to obtain appropriate charging power, which in turn limits the full performance of charging piles. At the same time, low-power charging piles will find it difficult to meet the needs of electric vehicles with high power requirements for fast charging, thereby extending the charging time, reducing user experience, and potentially constraining the healthy development of the charging pile market.

[0005] Therefore, how to optimize the power allocation strategy of charging piles to adapt to the diverse needs of the electric vehicle market has become a problem that needs to be solved urgently.

After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0076] An embodiment of the present invention provides a charging pile power distribution system, comprising n charging guns and n charging modules, wherein one charging gun is directly connected to one charging module, thereby ensuring directness and high efficiency of power transmission;

[0077] The n charging guns include m fast charging guns and nm slow charging guns to meet the charging needs of different users;

[0078] Each of the fast charging guns is directly connected to a corresponding charging module, and is connected to the remaining n-1 charging modules through switches, so that all the charging modules can be mobilized; this design enables the fast charging gun to make full use of all available resources and provide faster and more efficient charging services for electric vehicles that require high-power charging.

[0079] Each of the slow charging guns is directly connected to a corresponding charging module, and is connected to some of the charging modules through switches, so that some of the charging modules can be mobilized; this design not only ensures basic charging needs, but also optimizes resource allocation and improves the overall efficiency of the system.

[0080] Among them, n and m are both natural numbers, and m is less than n, which ensures the rationality and practicality of the system configuration.

[0081] Please refer to Figure 1 In one implementation of this embodiment, n is 12, and m is 2, that is, there are 12 charging guns and 12 charging modules, and the 12 charging guns include 2 fast charging guns and 10 slow charging guns;

[0082] Each of the fast charging guns can mobilize one of the charging modules corresponding to it and the remaining 11 charging modules;

[0083] Each of the slow charging guns can mobilize the corresponding one of the charging modules and any other four of the charging modules.

[0084] It should be noted that this embodiment distributes the charging power of 600KW to 12 charging guns, with each charging module being 50KW. In this way, the fast charging gun can output a maximum power of 600KW, and the slow charging gun can output a maximum charging power of 250KW.

[0085] When charging, the power distribution system can allocate at least 50KW charging modules for charging according to the demand transmitted by the electric vehicle. When it is detected that the power of the allocated charging module is less than the power required by the electric vehicle, the switches of other idle charging modules can be closed to allow the energy of the idle charging modules to be transmitted to the electric vehicle through the copper bus. If the charging power of the charged module is still insufficient, the idle modules will continue to be put into use until the power meets the charging demand of the electric vehicle, or the system itself has no idle modules.

[0086] Please continue to refer to Figure 1 In one implementation of this embodiment, the two fast charging guns are respectively a first charging gun ( Figure 1 The figure shows charging gun 1) and the seventh charging gun ( Figure 1 The charging gun 7 is shown in the figure);

[0087] The 10 slow charging guns are the second charging gun, the third charging gun, the fourth charging gun, the fifth charging gun, the sixth charging gun, the eighth charging gun, the ninth charging gun, the tenth charging gun, the eleventh charging gun and the twelfth charging gun ( Figure 1 denoted as charging guns 2-6 and charging guns 8-12 in sequence);

[0088] The 12 charging modules are respectively a first charging module, a second charging module, a third charging module, a fourth charging module, a fifth charging module, a sixth charging module, a seventh charging module, an eighth charging module, a ninth charging module, a tenth charging module, an eleventh charging module and a twelfth charging module ( Figure 1 1 to 12 in sequence);

[0089] The first charging gun is directly connected to the corresponding first charging module;

[0090] The second charging gun is directly connected to the corresponding second charging module;

[0091] The third charging gun is directly connected to the corresponding third charging module;

[0092] The fourth charging gun is directly connected to the corresponding fourth charging module;

[0093] The fifth charging gun is directly connected to the corresponding fifth charging module;

[0094] The sixth charging gun is directly connected to the corresponding sixth charging module;

[0095] The seventh charging gun is directly connected to the corresponding seventh charging module;

[0096] The eighth charging gun is directly connected to the corresponding eighth charging module;

[0097] The ninth charging gun is directly connected to the corresponding ninth charging module;

[0098] The tenth charging gun is directly connected to the corresponding tenth charging module;

[0099] The eleventh charging gun is directly connected to the corresponding eleventh charging module;

[0100] The twelfth charging gun is directly connected to the corresponding twelfth charging module.

[0101] It should be noted that the system also includes several copper bars, of which 12 are main copper bars, and these 12 copper bars are directly connected to 12 charging modules ( Figure 1 The 12 copper bars are indicated by vertical red thin lines. The remaining copper bars cooperate with the corresponding switches as the power transfer path between each charging module ( Figure 1 The remaining copper bars are indicated by horizontal black thin lines, and the horizontal black switches are switches in the power transfer circuit).

[0102] Please continue to refer to Figure 1 In one implementation of this embodiment, the second charging module, the third charging module, the fourth charging module, the fifth charging module and the sixth charging module are respectively connected to the first charging module through one switch;

[0103] The second charging module and the fourth charging module are connected to the third charging module via a switch respectively;

[0104] The fourth charging module and the sixth charging module are respectively connected to the fifth charging module via a switch;

[0106] Please continue to refer to Figure 1 In one implementation of this embodiment, the eighth charging module, the ninth charging module, the tenth charging module, the eleventh charging module and the twelfth charging module are respectively connected to the seventh charging module through one switch;

[0107] The eighth charging module and the tenth charging module are connected to the ninth charging module via a switch respectively;

[0108] The tenth charging module and the twelfth charging module are connected to the eleventh charging module via a switch respectively;

[0115] The twelfth charging module is connected to the sixth charging module via a switch.

[0116] It should be noted that the power distribution matrix design of this embodiment can ensure that the power distribution of 2 fast charging guns and 10 slow charging guns can be met at the same time by using a small number of switches and copper bars, so that it can make full use of the 600KW charging system. At the same time, it is small in size and does not need to occupy a large space.

[0118] When the first charging gun calls all the charging modules, the ninth charging module is connected to the third charging module through the corresponding switch and shares the power transfer path of the third charging module;

[0122] It should be noted that Figure 2 In the figure, the thick red line is the first charging gun currently charging, the thick cyan line is the power transfer path of the remaining charging modules, and the thick blue line is the power transfer path when two charging modules share one switch, which can save the use of switches and copper bars.

[0123] Please refer to Figure 3 In one implementation of this embodiment, when the seventh charging gun calls all the charging modules, the second charging module is connected to the eighth charging module through the corresponding switch, and shares the power mobilization path of the eighth charging module;

[0125] When the seventh charging gun calls all the charging modules, the fourth charging module is connected to the tenth charging module through the corresponding switch, and shares the power transfer path of the tenth charging module;

[0126] When the seventh charging gun calls all the charging modules, the fifth charging module is connected with the eleventh charging module through the corresponding switch, and shares the power transfer path of the eleventh charging module;

The power transfer path diagrams of the remaining slow charging guns are similar to those of the second and third charging guns.

[0131] It is understandable that if you want to charge at full power, there must be no gun being charged on the power mobilization path of the gun, otherwise the power circuit will be interrupted.

[0132] Although the terms such as charging pile and charging module are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
