Description

Technical Field

[0001] This application relates to the field of new energy technology, and more specifically, to a charging system and a sharing system in the field of new energy technology. Background Technology

[0002] With the development of technology, the charging power requirements of terminals (such as electric vehicles, EVs) are increasing. EVs are typically charged through charging systems (such as charging stations). Because different EVs require significantly different charging voltages, a single charging system cannot charge different EVs simultaneously. Furthermore, the output power of a single charging system is insufficient to meet the high-power charging demands of EVs, affecting the charging speed. Alternatively, the output power of a single charging system may far exceed the high-power fast-charging requirements of EVs, resulting in idle power modules in the charging system. Therefore, there is an urgent need for a technical solution that can charge different EVs simultaneously. Summary of the Invention

[0003] This application provides a charging system and a sharing system that can not only charge different electric vehicles simultaneously, but also achieve power sharing between different charging systems during the charging process.

[0004] In a first aspect, this application provides a charging system that may include multiple power modules, a distribution switch module, and multiple charging ports. The distribution switch module may include a first distribution unit and a second distribution unit.

[0005] The first part of the power modules in the multiple power modules (such as the power modules with odd serial numbers in the multiple power modules) can be connected to the first charging port in the multiple charging ports through the first allocation unit, and the second part of the power modules in the multiple power modules (such as the power modules with even serial numbers in the multiple power modules) can be connected to the second charging port in the multiple charging ports through the second allocation unit.

[0006] As can be seen from the above connection relationship, the first allocation unit corresponds to the first power module and the first charging port, and the second allocation unit corresponds to the second power module and the second charging port.

[0007] Each power module in the first and second power modules can be used to: convert a first power (represented by P1) from an external power source and output a second power (represented by P2). The first distribution unit can be used to: distribute the second power P2 output by each power module in the first power module to the first charging port.

[0008] Similar to the first allocation unit, the second allocation unit can be used to allocate the second power P2 output by each power module in the second power module to the second charging port.

[0009] Therefore, the first charging port can be used to charge a first terminal (such as a first electric vehicle) according to the power allocated by the first allocation unit.

[0010] Similar to the first charging port, the second charging port can be used to charge a second terminal (such as a second electric vehicle) according to the power allocated by the second distribution unit.

[0011] The charging system provided in this application distributes the power output (i.e., the second power P2) from each power module in the first and second power modules to different charging ports (i.e., the first charging port and the second charging port) through the first and second distribution units in the distribution switch module. This not only enables different electric vehicles (i.e., the first electric vehicle and the second electric vehicle) to be charged simultaneously through different charging ports, but also ensures that the output power of the charging system can meet the charging needs of different electric vehicles, thereby improving the charging speed of electric vehicles and the utilization rate of the power modules in the charging system.

[0012] It should be noted that the first power P1 can be provided to multiple power modules through the same external power supply (i.e., powering multiple power modules through the same external power supply), or the first power P1 can be provided to multiple power modules through different external power supplies.

[0013] Furthermore, the first power P1 mentioned above can be determined by the output voltage and output current of the external power supply, and the second power P2 mentioned above can be determined by the output voltage and output current of the power module.

[0014] Furthermore, the output voltage of the external power supply can be either DC or AC voltage.

[0015] Therefore, in one example, when the output voltage of the external power supply is a DC voltage, the power module described above can be a DC / DC conversion module. That is, the power module can convert a DC voltage of one voltage level from an external power supply to output a DC voltage of another voltage level (i.e., the output voltage of the power module can be a DC voltage).

[0016] For example, a power module can convert (e.g., step down) a high-voltage DC voltage from an external power source to output a low-voltage DC voltage.

[0017] In another example, when the output voltage of the external power supply is AC, the power module described above can be an alternating current (AC) / DC converter. That is, the power module can convert (or rectify) the AC voltage from the external power supply to output a DC voltage (i.e., the output voltage of the power module can be a DC voltage).

[0018] It should be noted that the nature of the output voltage of the power module (i.e., AC voltage or DC voltage) is determined by the nature of the voltage required by the electric vehicle (i.e., AC or DC power).

[0019] In one possible implementation, both the first allocation unit and the second allocation unit mentioned above may include multiple first switching switches. The second power output from multiple power modules is allocated to different charging ports through the multiple first switching switches, so as to enable simultaneous charging of different electric vehicles.

[0020] Furthermore, the distribution switch module may also include multiple second switching switches. These multiple second switching switches can connect two adjacent power modules in the first and second power modules. In other words, this application can achieve interconnection between two adjacent power modules in multiple power modules through multiple second switching switches, and distribute the second power from the power modules to the corresponding charging ports through corresponding first switching switches.

[0021] For example, the first and second power modules (which are adjacent to each other) in a plurality of power modules can be connected by a second switch (i.e., a second switch is set between the first and second power modules), and the third and fourth power modules (which are adjacent to each other) in a plurality of power modules can be connected by another second switch (i.e., a second switch is set between the third and fourth power modules).

[0022] For example, the first power module and the second power module (which are adjacent to each other) can be connected by a second switch, the second power module and the third power module (which are adjacent to each other) are not connected by a second switch (that is, there is no second switch between the second power module and the third power module), the third power module and the fourth power module are not connected by a second switch (that is, there is no second switch between the third power module and the fourth power module), and the fourth power module and the fifth power module (which are adjacent to each other) can be connected by another second switch.

[0023] Of course, the arrangement of the second switching switch is not limited to the situations listed above. As long as the power modules are adjacent, they can be connected through the second switching switch. The second power from the power module can be transmitted to the corresponding charging port through the second switching switch and the corresponding first switching switch. This application will not list them all.

[0024] Furthermore, the charging system provided in this application may also include a shared switch module and multiple shared ports. The multiple shared ports may include a first shared port and a second shared port.

[0025] Therefore, the shared switch module can connect the first part of the power module to the first shared port, and the shared switch module can connect the second part of the power module to the second shared port. In other words, the shared switch module enables the connection of multiple power modules to multiple shared ports.

[0026] In one possible implementation, the aforementioned shared switch module may include a first shared unit and a second shared unit. The first power module can be connected to a first shared port via the first shared unit, and the second power module can be connected to a second shared port via the second shared unit.

[0027] Optionally, both the first sharing unit and the second sharing unit may include multiple third switching switches.

[0028] Furthermore, the second power P2 output by each of the multiple power modules can be shared with the corresponding shared port through the corresponding third switching switch. At the same time, the power transmitted through the shared port (i.e. the power transmitted to the next charging system through the shared port) can be flexibly controlled by controlling the action of the third switching switch.

[0029] Furthermore, in addition to the first sharing unit and the second sharing unit, the shared switch module also includes multiple fourth switches. These multiple fourth switches can connect the first charging port, the second charging port, the first shared port, and the second shared port. In other words, this application can achieve interconnection between multiple charging ports and multiple shared ports through the fourth switches.

[0030] This application, by setting multiple fourth switching switches between multiple charging ports and multiple shared ports and controlling the operation of these fourth switches, enables the flexible allocation of the output power of multiple power modules to any charging port (such as the first charging port or the second charging port) or any shared port (such as the first shared port or the second shared port). This not only improves the charging power of a single charging port and the utilization rate of a single power module, but also enables the charging system to share power externally through the shared switch module, significantly enhancing the flexibility of the charging system.

[0031] In one possible implementation, the first, second, third, and fourth switching switches mentioned above can be contactors, semiconductor switches (also called solid-state switches), or semiconductor hybrid switches (which can be simply referred to as hybrid switches), etc.

[0032] Furthermore, the contactor described above can be a single-contact contactor (also called a single-pole contactor) or a double-contact contactor (also called a double-pole contactor). Of course, the contactor can also be other types of contactors, and the embodiments of this application do not limit the type of contactor.

[0033] Secondly, this application provides a shared system that may include at least two (i.e. more) of the above-mentioned charging systems connected in parallel.

[0034] The sharing system provided in this application not only enables simultaneous charging of different electric vehicles through the charging ports of different charging systems, but also achieves power sharing between different charging systems. Power sharing significantly improves the output power of the charging system (i.e., the charging power provided by the charging system to the electric vehicle through the charging port). In other words, power sharing does not affect the simultaneous charging of different electric vehicles by the sharing system, thereby improving the charging speed of electric vehicles and the utilization rate of the power modules in the charging system.

[0035] It should be noted that at least two charging systems can be powered by the same external power source, or each charging system can be powered independently by being equipped with its own external power source. This application does not limit the power supply method for at least two charging systems.

[0036] In one possible implementation, at least two charging systems can be connected via a power-sharing bus.

[0037] Furthermore, control switches or connectors can be installed on the power-sharing bus.

[0038] Optionally, the control switch may be a contactor, circuit breaker, or disconnector, etc., and this application does not limit it.

[0039] Alternatively, the connector may be a connector or a detachable copper busbar, etc., and this application does not limit the choice of which.

[0040] Of course, other devices capable of switching functions can also be installed on the power sharing bus, and the embodiments of this application do not limit this.

[0041] Furthermore, the power sharing bus can be made of copper, aluminum, or cable, etc., and this application does not limit it in this regard.

[0042] It should be understood that the second aspect of this application is consistent with the technical solution of the first aspect of this application, and the beneficial effects achieved by each aspect and the corresponding feasible implementation are similar, so they will not be repeated here.

[0066] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0067] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0068] The terms "first," "second," etc., used in the specification, embodiments, claims, and drawings of this application are for distinguishing purposes only and should not be construed as indicating or implying relative importance or order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as including a series of steps or units. A method, system, product, or apparatus is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0069] It should be understood that in this application, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0070] With the development of technology, the charging power requirements of terminals (using electric vehicles (EVs) in this application embodiment as an example) are increasing. EVs are typically charged through charging systems (such as charging stations). However, due to the significant differences in charging voltage required by different EVs, a single charging system cannot simultaneously charge different EVs through a charging port (such as a charging gun). Furthermore, the output power of a single charging system is insufficient to meet the high-power charging demands of EVs, affecting their charging speed. Alternatively, the output power of a single charging system may far exceed the high-power fast-charging requirements of EVs, resulting in idle power modules within the charging system.

[0071] To address the aforementioned technical problems, embodiments of this application provide a charging system, such as... Figure 1 As shown. A charging system (CS) can include multiple power modules (i.e., Figure 1 The first part consists of power module A (including power module PM1, power module 3, ..., power module PM(N-1)) and the second part consists of power module B (including power module PM2, power module 4, ..., power module PMN), a distribution switch module (DSM), and multiple charging ports C (such as...). Figure 1 The charging port (CP1) and charging port (CP2) are included in the module. The distribution switch module (DSM) may include a distribution unit (DU)1 (i.e., the first distribution unit) and a distribution unit (DU2) (i.e., the second distribution unit).

[0072] Further, refer to Figure 1 Each power module in the first part of power module A and each power module in the second part of power module B (i.e. Figure 1The input terminals of power modules PM1 to PMT in the first part of the power module A are each connected to an external power supply (PS). The output terminal of the power module in the first part of the power module A is connected to the charging port CP1 through the distribution unit DU1. The charging port CP1 is connected to the electric vehicle EV1, thereby charging the electric vehicle EV1. Similarly, the output terminal of the power module in the second part of the power module B is connected to the charging port CP2 through the distribution unit DU2. The charging port CP2 is connected to the electric vehicle EV2, thereby charging the electric vehicle EV2.

[0073] As can be seen from the above connection relationship, the allocation unit DU1 corresponds to the first part of the power module A and the charging port CP1, and the allocation unit DU2 corresponds to the second part of the power module B and the charging port CP2.

[0074] exist Figure 1 Based on the structure shown, each power module (i.e., power module PM1 to power module PMN) in the first part power module A and the second part power module B can be used to: convert the first power (which can be represented by P1) from the external power supply PS and output the second power (which can be represented by P2).

[0075] Furthermore, the aforementioned allocation unit DU1 can be used to allocate the second power P2 output by each power module in the first power module A to the charging port CP1. Similarly, the aforementioned allocation unit DU2 can be used to allocate the second power P2 output by each power module in the second power module B to the charging port CP2.

[0076] Furthermore, charging port CP1 can be used to charge electric vehicle EV1 according to the power allocated by distribution unit DU1. Similarly, charging port CP2 can be used to charge electric vehicle EV2 according to the power allocated by distribution unit DU2.

[0077] The charging system provided in this application embodiment distributes the power (i.e., the second power P2) output from each power module in the first power module A and the second power module B to different charging ports (i.e., charging port CP1 and charging port CP2) through the distribution units DU1 and DU2 in the distribution switch module DSM. This not only enables the simultaneous charging of different electric vehicles (i.e., electric vehicle EV1 and the second electric vehicle EV2) through different charging ports, but also ensures that the output power of the charging system can meet the charging needs of different electric vehicles, thereby improving the charging speed of electric vehicles and the utilization rate of the power modules in the charging system.

[0078] It should be noted that the embodiments of this application take the example of providing the first power P1 to multiple power modules through the same external power supply PS (i.e., powering multiple power modules through the same external power supply PS). Of course, the first power P1 can also be provided to multiple power modules through different external power supplies.

[0079] Furthermore, the first power P1 mentioned above can be determined by the output voltage and output current of the external power supply PS, and the second power P2 mentioned above can be determined by the output voltage and output current of the power module.

[0080] Furthermore, the output voltage of the external power supply PS can be either DC voltage or AC voltage.

[0081] Therefore, in one example, when the output voltage of the external power supply PS is a DC voltage, the power module described above can be a DC / DC conversion module. That is, the power module can convert a DC voltage of one voltage level from the external power supply PS to output a DC voltage of another voltage level (i.e., the output voltage of the power module can be a DC voltage).

[0082] For example, a power module can convert (e.g., step down) a high-voltage DC voltage from an external power supply PS to output a low-voltage DC voltage.

[0083] In another example, when the output voltage of the external power supply PS is AC, the power module described above can be an AC / DC conversion module. That is, the power module can convert (or rectify) the AC voltage from the external power supply PS to output DC voltage (i.e., the output voltage of the power module can be DC voltage).

[0084] It should be noted that the nature of the power module's output voltage (i.e., AC voltage or DC voltage) is determined by the voltage required by the electric vehicle. Since electric vehicles typically require DC voltage, the output voltage of the power module in the above embodiments of this application is illustrated using DC voltage as an example.

[0085] Understandably, if the voltage required by an electric vehicle is AC voltage, the following two situations exist:

[0086] Scenario 1: When the output voltage of the external power supply PS is DC, the power module described above can be a DC / AC conversion module. That is, the power module can convert (or invert) the DC voltage from the external power supply PS to output AC voltage (i.e., the output voltage of the power module can be AC ​​voltage).

[0087] Scenario 2: When the output voltage of the external power supply PS is AC voltage, the power module described above can be an AC / AC conversion module. That is, the power module can convert one voltage level of AC voltage from the external power supply PS to output another voltage level of AC voltage (i.e., the output voltage of the power module can be AC ​​voltage).

[0088] For example, a power module can convert (e.g., step down) a high-voltage AC voltage from an external power supply PS to output a low-voltage AC voltage.

[0089] The following describes the charging system provided in this application embodiment, taking an even number (represented by N) of power modules in the charging system CS as an example.

[0090] In one possible implementation, such as Figure 2 The aforementioned distribution switch module DSM may include distribution unit DU1 and distribution unit DU2. Distribution unit DU1 may include a first switching switch S11 and a first switching switch S13 (i.e., connected to power module PM3). Figure 2 The first switch (not shown) is connected. Figure 2 (not shown), ..., first switching switch S1(N-1). Distribution unit DU2 may include first switching switch S12, first switching switch S14 (i.e., connected to power module PM4 (...)... Figure 2 The first switch (not shown) is connected. Figure 2 (not shown in the image), ..., the first switching switch S1N. (By...) Figure 2 It can be seen that the distribution switch module DSM includes N first switching switches: first switching switch S11, first switching switch S12, ..., first switching switch S1(N-1), and first switching switch S1N.

[0091] Among them, the first switching switch S11, the first switching switch S13, ..., the first switching switch S1(N-1) can... Figure 2 Power modules PM1, PM3, ..., PM(N-1) are connected to charging port CP1. First switching switches S12, S14, ..., S1N can... Figure 2 Power modules PM2, PM4, ..., PMN are connected to charging port CP2. In other words, this embodiment of the application can achieve the connection of N power modules to charging ports CP1 and CP2 through N first switching switches.

[0092] refer to Figure 2 Power modules PM1 to PMN can convert the first power P1 from the external power supply PS and output the second power P2.

[0093] Therefore, the first switching switch S11 can allocate the second power P2 output by the power module PM1 to the charging port CP1. At the same time, the first switching switch S1(N-1) can also allocate the second power P2 output by the power module PM(N-1), etc., to the charging port CP1. Of course, the first switching switch S13, etc., in the distribution switch module DSM can also allocate the second power P2 output by the power module PM3, etc., to the charging port CP1.

[0094] Similar to the first switching switches S11, S13, ..., S1(N-1), the first switching switch S12 can allocate the second power P2 output by the power module PM2 to the charging port CP2. Similarly, the first switching switch S1N can allocate the second power P2 output by the power module PMN to the charging port CP2. Likewise, the first switching switch S14 in the distribution switch module DSM can also allocate the second power P2 output by the power module PM4 to the charging port CP2.

[0095] Therefore, charging port CP1 can charge electric vehicle EV1 according to the power allocated by distribution unit DU1. Similarly, charging port CP2 can charge electric vehicle EV2 according to the power allocated by distribution unit DU2.

[0096] Further reference Figure 2 In addition to N first switching switches, the aforementioned distribution switch module DSM may also include N / 2 second switching switches (i.e., Figure 2 The second switching switch S21, ..., the second switching switch S2(N / 2) in the middle.

[0097] N / 2 second switching switches can Figure 2 In this embodiment, adjacent power modules are connected among the N power modules. In other words, the interconnection between adjacent power modules among the N power modules can be achieved using N / 2 second switching switches.

[0098] For example, the second switching switch S21 can be used to interconnect power module PM1 and power module PM2. Therefore, the second power P2 output by power module PM2 can be allocated to charging port CP1 via the second switching switch S21 and the first switching switch S11, and the second power P2 output by power module PM1 can be allocated to charging port CP2 via the second switching switch S21 and the first switching switch S12.

[0099] For example, via the second switching switch S22 (i.e., connected to the power module PM3) Figure 2 (not shown in the image) and power module PM4 ( Figure 2 The second switch between (not shown in the image) Figure 2 (Not shown in the image) Power modules PM3 and PM4 can be interconnected. Therefore, the second switch S22 and the first switch S13 (i.e., the first switch connected to power module PM3) can be used for interconnection. Figure 2 (Not shown) The second power P2 output by the power module PM4 is allocated to the charging port CP1. The second power P2 output by the power module PM3 can also be allocated to the charging port CP2 through the second switching switch S22 and the first switching switch S14 (i.e. the first switching switch connected to the power module PM4).

[0100] For example, the power module PMN and the power module PM(N-1) can be interconnected via the second switching switch S2(N / 2). Thus, the second power P2 output by the power module PMN can be allocated to the charging port CP1 via the second switching switch S2(N / 2) and the first switching switch S1(N-1), and the second power P2 output by the power module PM(N-1) can be allocated to the charging port CP2 via the second switching switch S2(N / 2) and the first switching switch S1N.

[0101] In one possible implementation, Figure 2 Based on this, the charging system CS provided in this application embodiment may further include a sharing switch module (SSM) and multiple shared ports (this application embodiment uses two shared ports, i.e. Figure 3 and Figure 5 Taking shared ports SP1 and SP2 as an example, for instance... Figure 3 and Figure 5 As shown.

[0102] Furthermore, the shared switch module SSM may include a sharing unit (SU)1 (i.e., the first shared unit) and a sharing unit SU2 (i.e., the second shared unit). For example... Figures 3 to 6 As shown, the shared unit SU1 may include a third switching switch S31 and a third switching switch S33 (i.e., connected to the power module PM3). Figure 3 and Figure 5 The third switch (not shown in the image) is connected. Figures 3 to 6 (not shown), ..., third switching switch S3(N-1). The shared unit SU2 may include third switching switch S32, third switching switch S34 (i.e., connected to power module PM4 (...)). Figure 3 and Figure 5 The third switch (not shown in the image) is connected. Figures 3 to 6 (not shown), ..., the third switching switch S3N.

[0103] Therefore, the shared unit SU1 (i.e., the third switch in the shared unit SU1) can connect the power modules in the first part of the power modules (i.e., power modules PM1, PM3, etc. with odd-numbered serial numbers) to the shared port SP1, and the shared unit SU2 (i.e., the third switch in the shared unit SU2) can connect the power modules in the second part of the power modules (i.e., power modules PM2, PM4, etc. with even-numbered serial numbers) to the shared port SP2. In other words, in this embodiment of the application, N power modules can be connected to the shared ports SP1 and SP2 through the shared units SU1 and SU2 in the shared switch module SSM.

[0104] refer to Figure 3 and Figure 4 The shared switch module SSM may include N third switching switches in shared unit SU1 and shared unit SU2 (i.e. Figure 3 and Figure 4 The third switching switch S31, the third switching switch S32, ..., the third switching switch S3(N-1), and the third switching switch S3N.

[0105] from Figure 3 As can be seen, N third switching switches can connect N power modules to shared port SP1 and shared port SP2. In other words, in this embodiment of the application, N power modules can be connected to shared port SP1 and shared port SP2 through N third switching switches.

[0106] Combination Figure 3 As can be seen from the above connection relationship, the second power P2 output by each of the N power modules can be shared with the corresponding shared port through the corresponding third switching switch. At the same time, the power transmitted by the shared port (i.e. the power transmitted to the next charging system through the shared port) can be controlled by controlling the action of the third switching switch.

[0107] For example, the second power P2 output by the power module PM1 can be shared with the shared port SP1 through the third switching switch S31.

[0108] For example, the second power P2 output by the power module PM(N-1) can be shared with the shared port SP1 through the third switching switch S3(N-1).

[0109] It should be noted that the third switching switch S33 and the third switching switch S35 (i.e., the power module PM5) Figure 3 The third switch (not shown in the image) is connected. Figure 3(Not shown in the image) etc. can also share the second power P2 output by the corresponding power module (e.g., the power module PM3 corresponding to the third switching switch S33, and the power module PM5 corresponding to the third switching switch S35) to the shared port SP1.

[0110] For example, the second power P2 output by the power module PM2 can be shared with the shared port SP2 via the third switching switch S32.

[0111] For example, the second power P2 output by the power module PMN can be shared with the shared port SP2 through the third switching switch S3N.

[0112] It should be noted that the third switching switch S34 and the third switching switch S36 (i.e., the power module PM6) Figure 3 The third switch (not shown in the image) is connected. Figure 3 (Not shown in the image) etc. can also share the second power P2 output by the corresponding power module (e.g., power module PM4 corresponding to the third switching switch S34, and power module PM6 corresponding to the third switching switch S36) to the shared port SP2.

[0113] exist Figure 3 and Figure 4 Based on this, the aforementioned shared switch module SSM includes, in addition to the N third switching switches (i.e., in shared unit SU1 and shared unit SU2) Figure 5 and Figure 6 The shared switch module SSM may also include multiple fourth switches (i.e., the third switching switches S31, S32, ..., S3(N-1), S3N). Figure 5 and Figure 6 The fourth switching switches S41, S42 and S43 in the above, such as Figure 5 and Figure 6 As shown.

[0114] from Figure 5 It can be seen that the third switch in the shared unit SU1 can switch between power module PM1 and power module PM3. Figure 5 (Not shown in the image), ..., power module PM(N-1) is connected to the shared port SP1. The third switch in the shared unit SU2 can connect power module PM2, power module PM4 (... Figure 5(Not shown in the diagram), ..., power module PMN is connected to shared port SP2. Fourth switching switches S41, S42, and S43 can connect charging port CP1, charging port CP2, shared port SP1, and shared port SP2. In other words, this embodiment can achieve the connection of N power modules to shared port SP1 and shared port SP2 through N third switching switches. Furthermore, this embodiment can also achieve the connection between charging port CP1, charging port CP2, shared port SP1, and shared port SP2 through fourth switching switches S41, S42, and S43.

[0115] from Figure 5 As can be seen from the above connection relationship, the power transmitted through the shared port can be controlled by multiple third and fourth switches. At the same time, the second power P2 output by each of the N power modules can be shared among the charging port CP1, the charging port CP2, the shared port SP1, and the shared port SP2. In other words, the output power of multiple power modules can be distributed to any charging port or any shared port through multiple fourth switches.

[0116] This application embodiment can allocate the output power of any power module to any charging port and any shared port by using the Distributed Switch Module (DSM) and the Shared Switch Module (SSM). This not only improves the charging power of a single charging port and the utilization rate of a single power module, but also enables the charging system to share power externally through the Shared Switch Module (SSM), greatly enhancing the flexibility of the charging system.

[0117] In one possible implementation, embodiments of this application can... Figure 5 Based on this, provide such Figure 7 The charging system CS. (Reference) Figure 7 The charging system CS may also include N fifth switching switches (i.e. Figure 7 The fifth switching switch S51, the fifth switching switch S52, ..., the fifth switching switch S5(N-1), and the fifth switching switch S5N.

[0118] from Figure 7 As can be seen, N power modules PM can be connected to their respective charging ports via the corresponding fifth switch.

[0119] For example, the power module PM1 can be connected to the charging port CP3 via the fifth switching switch S51.

[0120] For example, the power module PM2 can be connected to the charging port CP4 via the fifth switch S52.

[0121] This application embodiment can provide more charging ports through N fifth switching switches (i.e. Figure 7 The charging system CS can use charging ports CP3 and CP4 to share the output power of multiple power modules. Moreover, the charging system CS can charge more electric vehicles (such as electric vehicles EV3 and EV4) through charging ports CP3 and CP4.

[0122] In another possible implementation, embodiments of this application may... Figure 5 Based on this, provide such Figure 8 The charging system CS is shown. (Reference) Figure 8 The charging system CS can eliminate the need for a second switching switch (e.g., it can eliminate the need for a second switching switch). Figure 5 The second switching switch S21 between the medium power module PM1 and the power module PM2 is retained, while the second switching switch S2(N / 2) between the power module PM(N-1) and the power module PMN is retained.

[0123] In yet another possible implementation, embodiments of this application may... Figure 5 Based on this, provide such Figure 9 The charging system CS is shown. (As shown) Figure 9 As shown, the distribution switch module (DSM) may include a ratio Figure 5 More third toggle switches (such as) Figure 9 The third switching switch S31', the third switching switch S32', ..., the third switching switch S3(N-1)', and the third switching switch S3N'.

[0124] from Figure 9 As can be seen, N power modules PM can be connected to the corresponding shared ports through the corresponding third switching switches.

[0125] For example, power module PM1 can be connected to shared port SP1 via the third switch S31. Simultaneously, power module PM1 can also be connected to shared port SP2 via the third switch S31'.

[0126] For example, power module PM2 can be connected to shared port SP1 via the third switch S32'. Simultaneously, power module PM2 can also be connected to shared port SP2 via the third switch S32.

[0127] In yet another possible implementation, embodiments of this application may... Figure 5 Based on this, provide such Figure 10 The charging system CS is shown. (As shown) Figure 10 As shown, the shared switch module SSM can eliminate the need for a portion of the fourth switching switch (e.g., omitting the fourth switching switch). Figure 5(The fourth switch S42 between shared port SP1 and shared port SP2).

[0128] from Figure 10 It can be seen that the fourth switch S41 connects the charging port CP1 and the shared port SP1, and the fourth switch S43 connects the charging port CP2 and the shared port SP2.

[0129] Therefore, charging port CP1 and shared port SP1 can be connected via the fourth switch S41, and charging port CP2 and shared port SP2 can be connected via the fourth switch S43. In other words, in this embodiment of the application, the interconnection between charging port CP1, charging port CP2, shared port SP1, and shared port SP2 can be achieved through the fourth switch S41 and the fourth switch S43.

[0130] from Figure 10 As can be seen from the above connection relationship, the second power P2 output by each of the N power modules can be shared between the charging port CP1 and the sharing port SP1 through the fourth switching switch S41. At the same time, the second power P2 output by each of the N power modules can be shared between the charging port CP2 and the sharing port SP2 through the fourth switching switch S43.

[0131] It should be noted that, Figures 7 to 10 Only a partial structural diagram of the charging system provided in the embodiments of this application is shown. Of course, the technical solutions of the embodiments of this application can also be used in charging systems with other structures, and all similar structures are within the protection scope of the embodiments of this application.

[0132] The following section uses a charging system CS that includes 4 power modules (i.e., N is 4 as mentioned above) as an example to introduce the charging system provided in the embodiments of this application.

[0133] In one possible implementation, refer to Figure 11 The charging system CS can include 4 power modules (i.e. Figure 11 The power modules PM1, PM2, PM3, and PM4, the distribution switch module DSM, and multiple charging ports (i.e., Figure 11 (Charging ports CP1 and CP2 in the module). Among them, power modules PM1 and PM3 belong to the first part of the power modules, and power modules PM2 and PM4 belong to the second part of the power modules.

[0134] Furthermore, the distribution switch module DSM may include distribution unit DU1 and distribution unit DU2. Distribution unit DU1 may include first switching switch S11 and first switching switch S13. Distribution unit DU2 may include first switching switch S12 and first switching switch S14.

[0135] Optionally, the input terminals of power modules PM1, PM2, PM3, and PM4 are each connected to an external power supply PS. The output terminal of power module PM1 is connected to charging port CP1 via a first switch S11, and the output terminal of power module PM3 is connected to charging port CP1 via a first switch S13. Similarly, the output terminal of power module PM2 is connected to charging port CP2 via a first switch S12, and the output terminal of power module PM4 is connected to charging port CP2 via a first switch S14. Furthermore, charging port CP1 is connected to electric vehicle EV1 to charge EV1, and charging port CP2 is connected to electric vehicle EV2 to charge EV2.

[0136] As can be seen from the above connection relationship, the allocation unit DU1 corresponds to the first part of the power module and the charging port CP1, and the allocation unit DU2 corresponds to the second part of the power module and the charging port CP2.

[0137] exist Figure 11 Based on the structure shown, power modules PM1, PM2, PM3, and PM4 can convert the first power P1 from the external power source PS and output a second power P2. Distribution unit DU1 can allocate the second power P2 output by power modules PM1 and PM3 to charging port CP1. Similarly, distribution unit DU2 can allocate the second power P2 output by power modules PM2 and PM4 to charging port CP2.

[0138] In other words, the first switching switch S11 can allocate the second power P2 output by the power module PM1 to the charging port CP1, and the first switching switch S13 can also allocate the second power P2 output by the power module PM3 to the charging port CP1. The first switching switch S12 can allocate the second power P2 output by the power module PM2 to the charging port CP2, and the first switching switch S14 can also allocate the second power P2 output by the power module PM4 to the charging port CP2.

[0139] Furthermore, the aforementioned charging port CP1 can charge electric vehicle EV1 according to the power allocated by the distribution unit DU1. Similarly, charging port CP2 can charge electric vehicle EV2 according to the power allocated by the distribution unit DU2.

[0140] The charging system provided in this application embodiment distributes the power output (i.e., the second power P2) from each power module in the first and second power modules to the charging port CP1 and the charging port CP2 through the distribution unit DU1 and the distribution unit DU2. This not only enables simultaneous charging of electric vehicle EV1 and electric vehicle EV2 through different charging ports, but also ensures that the output power of the charging system can meet the charging needs of different electric vehicles, thereby improving the charging speed of electric vehicles and the utilization rate of the power modules in the charging system.

[0141] Further reference Figure 11 The distribution switch module (DSM) includes four first switching switches (i.e. Figure 11 In addition to the first switching switches S11, S12, S13, and S14, the distribution switch module DSM may also include two second switching switches (i.e., Figure 11 The second switching switch S21 and the first switching switch S22 in the middle.

[0142] from Figure 11 As can be seen, the second switching switch S21 can connect power module PM1 and power module PM2 (power modules PM1 and PM2 are adjacent), and the second switching switch S22 can connect power module PM3 and power module PM4 (power modules PM3 and PM4 are adjacent). In other words, the embodiments of this application can achieve interconnection between two adjacent power modules among the four power modules through two second switching switches.

[0143] For example, the second switching switch S21 can be used to interconnect the power module PM1 and the power module PM2. Then, the second power P2 from the power module PM2 can be allocated to the charging port CP1 by the second switching switch S21 and the first switching switch S11. The second power P2 from the power module PM1 can also be allocated to the charging port CP2 by the second switching switch S21 and the first switching switch S12.

[0144] For example, the second switching switch S22 can be used to interconnect the power module PM3 and the power module PM4. Then, the second power P2 from the power module PM4 can be allocated to the charging port CP1 through the second switching switch S22 and the first switching switch S13. The second power P2 from the power module PM3 can also be allocated to the charging port CP2 through the second switching switch S21 and the first switching switch S14.

[0145] In one possible implementation, Figure 11Based on this, the charging system CS provided in the embodiments of this application may further include a shared switch module SSM and two shared ports (i.e. Figure 12 Shared ports SP1 and SP2 in the network, such as Figure 12 As shown.

[0146] Furthermore, the shared switch module SSM may include a shared unit SU1 and a shared unit SU2. Shared unit SU1 may include a third switching switch S31 and a third switching switch S33. Shared unit SU2 may include a third switching switch S32 and a third switching switch S34.

[0147] from Figure 12 As can be seen, the third switch S31 can connect power module PM1 to the shared port SP1. The third switch S32 can connect power module PM2 to the shared port SP2. The third switch S33 can connect power module PM3 to the shared port SP1. The third switch S34 can connect power module PM4 to the shared port SP2.

[0148] based on Figure 12 Based on the above connection relationships, this embodiment of the application can realize power sharing between four power modules and shared ports SP1 and SP2 through a shared switch module SSM.

[0149] For example, the second power P2 output by the power module PM1 can be shared with the shared port SP1 through the third switching switch S31.

[0150] For example, the second power P2 output by the power module PM2 can be shared with the shared port SP2 through the third switching switch S32.

[0151] For example, the second power P2 output by the power module PM3 can be shared with the shared port SP1 through the third switching switch S33.

[0152] For example, the second power P2 output by the power module PM4 can be shared with the shared port SP2 through the third switching switch S34.

[0153] Further, refer to Figure 12 and Figure 13 The aforementioned shared switch module SSM includes, in addition to the four third switching switches in shared unit SU1 and shared unit SU2 (i.e., Figure 12 and Figure 13 The shared switch module SSM may also include three fourth switches (i.e., the third switching switches S31, S32, S33, and S34 in the module). Figure 12 and Figure 13The fourth switching switches S41, S42 and S43 in the middle.

[0154] from Figure 12 As can be seen, the fourth switch S41 connects the charging port CP1 and the shared port SP1, the fourth switch S42 connects the shared port SP1 and the shared port SP2, and the fourth switch S43 connects the charging port CP2 and the shared port SP2.

[0155] Therefore, four third switches can connect four power modules to shared ports SP1 and SP2, and three fourth switches can connect charging ports CP1, CP2, SP1, and SP2. In other words, this embodiment can connect four power modules to shared ports SP1 and SP2 using four third switches, and can also connect charging ports CP1, CP2, SP1, and SP2 using fourth switches S41, S42, and S43.

[0156] Combination Figure 12 As can be seen from the above connection relationship, the second power P2 output by each of the four power modules can be shared to the corresponding shared port through the corresponding third switch. At the same time, by setting the third switch, the power transmitted through the shared port (i.e., the power transmitted to the next charging system through the shared port) can be controlled. It can also be seen that multiple fourth switches can be used to distribute the output power of the four power modules to any charging port or any shared port.

[0157] The embodiments of this application can distribute the output power of any power module to any charging port and any shared port by using a distribution switch module and a shared switch module. This not only improves the charging power of a single charging port and the utilization rate of a single power module, but also enables the charging system to share power externally through the shared switch module, greatly improving the flexibility of the charging system.

[0158] The following describes the charging system provided in this application embodiment, taking an odd number (represented by N+1) of power modules in the charging system CS as an example.

[0159] In one possible implementation, refer to Figure 14 The aforementioned distribution switch module DSM may include distribution unit DU1 and distribution unit DU2. Distribution unit DU1 may include a first switching switch S11 and a first switching switch S13 (i.e., connected to power module PM3). Figure 14 The first switch (not shown in the image) is connected. Figure 14(not shown in the diagram), ..., first switching switch S1(N-1), first switching switch S1(N+1). Distribution unit DU2 may include first switching switch S12, first switching switch S14 (i.e., connected to power module PM4 (...)... Figure 14 The first switch (not shown) is connected. Figure 14 (not shown in the diagram), ..., first switching switch S1N, first switching switch S1(N+2). From Figure 14 It can be seen that the above-mentioned distribution switch module DSM may include a first switching switch S11, a first switching switch S12, ..., a first switching switch S1(N-1), a first switching switch S1N, a first switching switch S1(N+1), a first switching switch S1(N+2), for a total of N+2 first switching switches.

[0160] It should be noted that the connection relationship and power distribution process between the N first switching switches (i.e., first switching switch S11, first switching switch S12, ..., first switching switch S1(N-1), first switching switch S1N) and the corresponding power modules can be referred to the above text, and will not be repeated here in the embodiments of this application.

[0161] The first switching switch S1(N+1) can connect the power module PM(N+1) to the charging port CP1, and the first switching switch S1(N+2) can connect the power module PM(N+1) to the charging port CP2.

[0162] refer to Figure 14 The first switching switch S1(N+1) can allocate the second power P2 output by the power module PM(N+1) to the charging port CP1. At the same time, the first switching switch S1(N+2) can allocate the second power P2 output by the power module PM(N+1) to the charging port CP2.

[0163] Understandably, N+2 first switching switches can... Figure 14 The system contains N+1 power modules (i.e., power module PM1, power module PM2, ..., power module PM(N-1), power module PMN, power module PM(N+1)) and multiple charging ports (i.e. Figure 14 The charging ports CP1 and CP2 are connected. In other words, in this embodiment of the application, N+2 first switching switches can be used to connect N+1 power modules to the charging ports CP1 and CP2.

[0164] Further reference Figure 14 In addition to N+2 first switching switches, the aforementioned distribution switch module DSM may also include N / 2 second switching switches (i.e., Figure 14The second switching switch S21, ..., the second switching switch S2(N / 2) in the middle.

[0165] from Figure 14 It can be seen that N / 2 second switching switches can Figure 14 In this embodiment, adjacent power modules are connected among the N+1 power modules. That is, the interconnection between adjacent power modules among the N+1 power modules can be achieved using N / 2 second switching switches.

[0166] For example, the second switching switch S21 can be used to interconnect power module PM1 and power module PM2. Therefore, the second power P2 output by power module PM2 can be allocated to charging port CP1 via the second switching switch S21 and the first switching switch S11, and the second power P2 output by power module PM1 can be allocated to charging port CP2 via the second switching switch S21 and the first switching switch S12.

[0167] For example, via the second switching switch S22 (i.e., connected to the power module PM3) Figure 2 (not shown in the image) and power module PM4 ( Figure 2 The second switch between (not shown in the image) Figure 2 (Not shown in the image) This allows for the interconnection of power modules PM3 and PM4. Therefore, the second switch S22 and the first switch S13 (i.e., the first switch connected to power module PM3) can be used for interconnection. Figure 2 (Not shown in the middle) The second power P2 output by the power module PM4 is allocated to the charging port CP1. The second power P2 output by the power module PM3 can also be allocated to the charging port CP2 through the second switching switch S22 and the first switching switch S14 (i.e. the first switching switch connected to the power module PM4).

[0168] For example, the power module PMN and the power module PM(N-1) can be interconnected via the second switching switch S2(N / 2). Thus, the second power P2 output by the power module PMN can be allocated to the charging port CP1 via the second switching switch S2(N / 2) and the first switching switch S1(N-1), and the second power P2 output by the power module PM(N-1) can be allocated to the charging port CP2 via the second switching switch S2(N / 2) and the first switching switch S1N.

[0169] It should be noted that the power module PM(N+1) does not need to be connected to the second switching switch.

[0170] In one possible implementation, Figure 14Based on this, the charging system CS provided in this application embodiment may further include a shared switch module SSM and multiple shared ports (this application embodiment uses 2 shared ports, i.e. Figure 15 and Figure 17 Taking shared ports SP1 and SP2 as an example, for instance... Figure 15 and Figure 17 As shown.

[0171] Furthermore, the shared switch module SSM may include a shared unit SU1 (i.e., the first shared unit) and a shared unit SU2 (i.e., the second shared unit), such as... Figures 15 to 18 As shown. The shared unit SU1 may include a third switching switch S31 and a third switching switch S33 (i.e., connected to the power module PM3). Figure 15 and Figure 17 The third switch (not shown in the image) is connected. Figures 15 to 18 (not shown), ..., third switching switch S3(N-1) and third switching switch S3(N+1). The shared unit SU2 may include third switching switch S32, third switching switch S34 (i.e., connected to power module PM4 (...)... Figure 15 and Figure 17 The third switch (not shown in the image) is connected. Figures 15 to 18 (not shown), ..., third switching switch S3N and third switching switch S3(N+2).

[0172] Therefore, the third switch in the shared unit SU1 can connect power modules PM1, PM3, ..., PM(N-1) and PM(N+1) to the shared port SP1, and the third switch in the shared unit SU2 can connect power modules PM2, PM4, ..., PMN and PM(N+1) to the shared port SP2. In other words, this embodiment of the application can achieve the connection of N+1 power modules to the shared ports SP1 and SP2 through the shared units SU1 and SU2 in the shared switch module SSM.

[0173] Understandably, the shared switch module (SSM) can connect N+1 power modules to shared ports SP1 and SP2. In other words, this embodiment of the application can achieve the connection of N+1 power modules to shared ports SP1 and SP2 through the shared switch module (SSM).

[0174] refer to Figure 15 and Figure 16 The shared switch module SSM may include N+2 third switching switches in shared unit SU1 and shared unit SU2 (i.e. Figure 15 and Figure 16The third switching switch S31, the third switching switch S32, ..., the third switching switch S3(N-1), the third switching switch S3N, the third switching switch S3(N+1), and the third switching switch S3(N+2)).

[0175] from Figure 15 As can be seen, N+2 third switching switches can connect N+1 power modules to shared port SP1 and shared port SP2. In other words, in this embodiment of the application, N power modules can be connected to shared port SP1 and shared port SP2 through N third switching switches.

[0176] For example, the third switching switch S3(N+1) can connect the power module PM(N+1) to the shared port SP1. Thus, the third switching switch S3(N+1) can allocate the second power P2 output by the power module PM(N+1) to the shared port SP1.

[0177] For example, the third switching switch S3(N+2) can connect the power module PM(N+1) to the shared port SP2, so the third switching switch S3(N+2) can allocate the second power P2 output by the power module PM(N+1) to the shared port SP2.

[0178] Combination Figure 15 As can be seen from the above connection relationship, the second power P2 output by each of the N+1 power modules can be shared with the corresponding shared port through the corresponding third switching switch. At the same time, the power transmitted by the shared port (i.e. the power transmitted to the next charging system through the shared port) can be controlled by controlling the action of the third switching switch.

[0179] It should be noted that the connection relationship and power allocation process between the N first switching switches (i.e., first switching switches S11, S12, ..., first switching switches S1(N-1), first switching switches S1N), N / 2 second switching switches (i.e., second switching switches S21, ..., second switching switches S2(N / 2)) and the N third switching switches (i.e., third switching switches S31, third switching switches S32, ..., third switching switches S3N) and their respective power modules PM can be referred to the above, and will not be repeated in the embodiments of this application.

[0180] exist Figure 15 and Figure 16 Based on this, the aforementioned shared switch module SSM includes N+2 third switching switches (i.e. Figure 17 and Figure 18The shared switch module SSM may also include multiple fourth switches (i.e., the third switching switches S31, S32, ..., S3(N-1), S3N, S3(N+1), S3(N+2)). Figure 5 and Figure 6 The fourth switching switches S41, S42 and S43 in the above, such as Figure 17 and Figure 18 As shown.

[0181] from Figure 17 It can be seen that the third switch in the shared unit SU1 can connect power modules PM1, PM3, ..., PM(N-1) and PM(N+1) to the shared port SP1. The third switch in the shared unit SU2 can connect power modules PM2, PM4, ..., PMN and PM(N+1) to the shared port SP2. The fourth switches S41, S42, and S43 can connect charging ports CP1, CP2, SP1, and SP2. In other words, this embodiment can connect N+1 power modules to SP1 and SP2 using N+2 third switches. Furthermore, this embodiment can also interconnect charging ports CP1, CP2, SP1, and SP2 using the fourth switches S41, S42, and S43.

[0182] from Figure 17 As can be seen from the above connection relationship, the second power P2 output by each of the N+1 power modules can be shared among the charging port CP1, charging port CP2, shared port SP1 and shared port SP2 through multiple third switching switches and multiple fourth switching switches, and the power transmitted through the shared port can be controlled at the same time.

[0183] This application embodiment can allocate the output power of any power module to any charging port and any shared port by using the Distributed Switch Module (DSM) and the Shared Switch Module (SSM). This not only improves the charging power of a single charging port and the utilization rate of a single power module, but also enables the charging system to share power externally through the Shared Switch Module (SSM), greatly enhancing the flexibility of the charging system.

[0184] It should be noted that, Figures 7 to 10Only a partial structural diagram of the charging system provided in the embodiments of this application is shown. Of course, the technical solutions of the embodiments of this application can also be used in charging systems with other structures, and all similar structures are within the protection scope of the embodiments of this application.

[0185] In one possible implementation, the first, second, third, and fourth switching switches mentioned above can be contactors, semiconductor switches (also called solid-state switches), or semiconductor hybrid switches (which can be simply referred to as hybrid switches), etc.

[0186] Furthermore, the contactor described above can be a single-contact contactor (also called a single-pole contactor) or a double-contact contactor (also called a double-pole contactor). Of course, the contactor can also be other types of contactors, and this application embodiment does not limit this.

[0187] In one possible implementation, embodiments of this application provide a sharing system (SS), such as... Figure 19 As shown. The shared system SS may include M (M is greater than or equal to 2, i.e., at least 2) parallel charging systems (i.e., Figure 19 The charging system CS1, charging system CS2, ..., charging system CSM.

[0188] The sharing system provided in this application embodiment can not only charge different electric vehicles simultaneously through the charging ports of different charging systems, but also achieve power sharing between different charging systems. Through power sharing, the output power of the charging system (i.e., the charging power provided by the charging system to the electric vehicle through the charging port) is significantly improved. In other words, power sharing does not affect the simultaneous charging of different electric vehicles by the sharing system, thereby improving the charging speed of electric vehicles and the utilization rate of the power modules in the charging system.

[0189] Meanwhile, the charging systems in the shared system provided in this application embodiment are all independent modules. It can be seen that the shared system has a high degree of modularity and can select the number of charging systems according to the actual charging needs of electric vehicles, which is highly flexible.

[0190] In one possible implementation, such as Figure 20 As shown, adjacent charging systems can be connected via a power-sharing bus (also called a connecting conductor).

[0191] For example, charging system CS1 (which can be the shared port SP1 of charging system CS1) and charging system CS2 (which can be the shared port SP1 of charging system CS1) are connected through a power sharing bus (PSB) 1.

[0192] Understandably, the shared port SP1 of the charging system CS1 can be considered as the shared output port of the charging system CS1. Since the charging system CS1 is the first charging system of the shared system SS, the charging system CS1 can be configured with only one shared port (as the shared output port of the charging system CS1).

[0193] It's understandable that, since intermediate charging systems (i.e., other charging systems in the shared system SS besides charging systems CS1 and CSM, such as charging system CS2) need to connect with adjacent charging systems, intermediate charging systems like charging system CS2 can have two shared ports: shared port SP1 and shared port SP2. Here, if power is transferred from charging system CS1 to intermediate charging systems like charging system CS2, then shared port SP1 of intermediate charging systems like charging system CS2 can be considered a shared input port, and shared port SP2 of intermediate charging systems like charging system CS2 can be considered a shared output port.

[0194] Of course, since power transmission is bidirectional, if power is transmitted from the intermediate charging system such as charging system CS2 to charging system CS1, then the shared port SP1 of the intermediate charging system such as charging system CS2 can be considered as a shared output port, and the shared port SP2 of the intermediate charging system such as charging system CS2 can be considered as a shared input port of the intermediate charging system such as charging system CS2 (here, it can be that the intermediate charging system such as charging system CS3 transmits power to charging system CS2).

[0195] Similar to the charging system CS1, the charging system CSM is the last charging system in the shared system SS, so the charging system CSM can also be configured with only one shared port (as the shared input port of the charging system CSM).

[0196] Of course, if it is necessary to further achieve power sharing based on M charging systems in the shared system, or to achieve mass production of charging systems, a shared port SP2 can be set for charging system CS1. Figure 20 (Not shown in the image, i.e., the shared input port of the charging system CS1), a shared port SP2 can also be set for the charging system CSM. Figure 20 (Not shown, i.e., the shared output terminal of the charging system CSM). In other words, the embodiments of this application do not limit the number of shared ports set in the charging system.

[0197] from Figure 20 As can be seen, the embodiments of this application can charge different electric vehicles simultaneously using different charging systems.

[0198] For example, different electric vehicles (such as electric vehicle EV1 and electric vehicle EV2) can be charged through different charging ports of the charging system CS1 (such as charging port CP1 and charging port CP2 of the charging system CS1).

[0199] For example, different electric vehicles (such as electric vehicle EV3 and electric vehicle EV4) can be charged through different charging ports of the charging system CS2 (such as charging port CP1 and charging port CP2 of the charging system CS2).

[0200] For example, different electric vehicles (such as electric vehicle EV5 and electric vehicle EV6) can be charged through different charging ports of the charging system CSM (such as charging port CP1 and charging port CP2 of the charging system CSM).

[0201] Combination Figure 7 Understandable. Figure 20 Each charging system in the shared system shown can be equipped with more charging ports (i.e., not just the two charging ports CP1 and CP2).

[0202] For example, the charging system CS1 can also be equipped with a charging port CP3 ( Figure 20 (not shown in the image) and charging port CP4 ( Figure 20 (Not shown in the image) While sharing between different charging systems, multiple electric vehicles can be charged through multiple charging ports.

[0203] from Figure 20 It can also be seen that, in order to improve the reliability of the sharing system, each charging system (which can be considered as the power module of the charging system) in the sharing system provided in this application embodiment can be powered by a different external power source.

[0204] For example, the charging system CS1 is powered by an external power supply SP1.

[0205] For example, the charging system CS2 is powered by an external power source SP2.

[0206] For example, the charging system CSM is powered by an external power source SPM.

[0207] Of course, in this embodiment, all charging systems in the shared system can be powered by the same external power source, or multiple (e.g., 2 or 3) charging systems can be powered by one external power source (i.e., one external power source powers some of the charging systems). This embodiment does not limit the power supply method for the charging systems in the shared system.

[0208] In one example, such as Figure 21 As shown, the shared system may include K parallel charging systems (i.e., Figure 21The system comprises charging systems CS1, CS2, ..., CSK, each consisting of N (an even number) power modules. Adjacent charging systems are connected via a power-sharing bus. For example, charging systems CS1 and CS2 are connected via a power-sharing bus PSB1.

[0209] from Figure 21 It can be seen that charging system CS1 can charge different electric vehicles through charging ports CP1 and CP2, and can also share power with charging system CS2 through shared port SP2.

[0210] Similar to charging system CS1, charging system CS2 can receive power from charging system CS1 shared by charging system CS1 through its own shared port SP1, and charge different electric vehicles through charging ports CP1 and CP2. Simultaneously, charging system CS2 can share power from charging system CS1 to charging system CS2 through its three fourth switching switches, or share power from charging system CS1 to charging system CS3 (such as charging system CS3 in...) through shared ports SP1 and SP2 and one of the fourth switching switches. Figure 21 (Not shown in the image).

[0211] It should be noted that the process of sharing the power of charging system CS1 to charging system CS2 through the three fourth switching switches of charging system CS2 will not affect the use of the charging ports inside charging system CS2. In other words, it will not affect the charging system CS2 from charging electric vehicles through its own charging ports CP1 and CP2.

[0212] It should also be noted that in the process of sharing the power of charging system CS1 to the subsequent charging system CS2 through the shared port SP2 of charging system CS2, the three fourth switching switches of charging system CS2 provide a power transmission channel for sharing the power of charging system CS1 to the subsequent charging system CS2. This process will not affect the use of the charging ports inside charging system CS2.

[0213] It should be noted that, due to the bidirectional transmission characteristics of power, as mentioned above, charging system CS1 can share its power with charging system CS2, and charging system CS2 can also share its power with the next charging system CS. Of course, charging system CS2 can also share its power with charging system CS1.

[0214] It should also be noted that, Figure 21 The remaining charging systems CS in the provided shared system (such as charging system CSK and charging system CS(K-1)) (charging system CS(K-1) in Figure 21 The power sharing principle between (not shown in the figure) and (etc.) is the same as above, and will not be described in detail in the embodiments of this application.

[0215] In another example, combining the above... Figure 12 The illustration includes four charging systems (CS) (each charging system CS includes four power modules PM) to provide a detailed description of the shared system provided in the embodiments of this application.

[0216] like Figure 22 As shown, the shared system may include K parallel charging systems (i.e., Figure 21 The charging systems are CS1, CS2, ..., CSK. Adjacent charging systems are connected via a power-sharing bus. For example, charging system CS1 and charging system CS2 are connected via a power-sharing bus PSB1.

[0217] from Figure 22 It can be seen that charging system CS1 can charge different electric vehicles through charging ports CP1 and CP2, and can also share power with charging system CS2 through shared port SP2.

[0218] Similarly, charging system CS2 can receive the shared power from charging system CS1 through its own shared port CP1, and charge different electric vehicles through charging ports CP1 and CP2 of charging system CS2. Simultaneously, charging system CS2 can also transmit shared power to the next charging system CS (such as charging system CS3) through its shared port SP2. Figure 22 (Not shown in the image).

[0219] It should be noted that, due to the bidirectional transmission characteristics of power, as mentioned above, charging system CS1 can share its power with charging system CS2, and charging system CS2 can also share its power with the next charging system CS. Of course, charging system CS2 can also share its power with charging system CS1.

[0220] It should also be noted that, Figure 22 The other charging systems provided in the shared system (such as charging system CSK and charging system CS(K-1)) (charging system CS(K-1) in Figure 22 The power sharing principle between (not shown in the figure) and (etc.) is the same as above, and will not be described in detail in the embodiments of this application.

[0221] In yet another example, combining the above... Figure 17 The illustration includes K charging systems (each charging system CS includes N+1 (i.e., an odd number) power modules) to provide a detailed description of the shared system provided in the embodiments of this application.

[0222] like Figure 23 As shown, the shared system may include K parallel charging systems (i.e., Figure 21 The charging systems are CS1, CS2, ..., CSK. Adjacent charging systems are connected via a power-sharing bus. For example, charging system CS1 and charging system CS2 are connected via a power-sharing bus PSB1.

[0223] from Figure 23 It can be seen that charging system CS1 can charge different electric vehicles through charging ports CP1 and CP2, and can also share power with charging system CS2 through shared port SP2.

[0224] Similarly, charging system CS2 can receive power shared by charging system CS1 through its shared port SP1, and charge different electric vehicles through charging ports CP1 and CP2. Simultaneously, charging system CS2 can also transmit power sharing to the next charging system CS (such as charging system CS3) through its shared port SP2. Figure 23 (Not shown in the image).

[0225] It should be noted that, due to the bidirectional transmission characteristics of power, as mentioned above, charging system CS1 can share its power with charging system CS2, and charging system CS2 can also share its power with the next charging system CS. Of course, charging system CS2 can also share its power with charging system CS1.

[0226] It should also be noted that, Figure 23 The other charging systems provided in the shared system (such as charging system CSK and charging system CS(K-1)) (charging system CS(K-1) in Figure 23 The power sharing principle between (not shown in the figure) and (etc.) is the same as above, and will not be described in detail in the embodiments of this application.

[0227] Combination Figure 21 , Figure 22 and Figure 23As can be seen, different charging systems in the shared system can share power, and this is not limited by the number of power modules (PMs) in each charging system. In other words, regardless of the number of power modules in a charging system, different charging systems in the shared system can share power, and each charging system can charge different electric vehicles while sharing power.

[0228] In summary, the embodiments of this application provide the above-mentioned... Figure 21 , Figure 22 and Figure 23 The shared system shown, which includes K charging systems, not only enables each charging system to charge different electric vehicles, but also enables power sharing among all charging systems.

[0229] It should be noted that a detailed description of the charging system can be found above, and the embodiments in this application will not be repeated here.

[0230] In one possible implementation, the power-sharing bus connecting adjacent charging systems can be a copper busbar, an aluminum busbar, or a cable, etc. The embodiments of this application do not limit the type of power-sharing busbar.

[0231] In another possible implementation, a control switch or connector can be installed on the aforementioned power-sharing bus.

[0232] Optionally, the control switch described above can be a contactor, circuit breaker, or disconnector, etc. Similarly, the contactor here can be a single-contact contactor (also called a single-pole contactor) or a double-contact contactor (also called a double-pole contactor). Of course, the contactor can also be other types of contactors, and this application embodiment does not limit this.

[0233] Optionally, the aforementioned connectors may be connectors or detachable copper busbars, etc., and this application does not limit them.

[0234] Of course, other devices capable of switching functions can also be installed on the power sharing bus, and the embodiments of this application do not limit this.
