An embodiment of the present disclosure provides a charging host 100, referring to fig. 1, including a box 10, a conversion module 101 and a power distribution module 102, where the conversion module 101 and the power distribution module 102 are disposed in the box 10, the conversion module 101 and the power distribution module 102 are electrically connected, and the power distribution module 102 and the conversion module 101 are used for connecting a dc power supply module and an electric load.

The dc power module may be disposed in the case 10 or disposed outside the case 10, and in the structure of the charging host 100 provided in the present disclosure, the dc power module is illustrated as being disposed outside the case 10. The DC power supply module is arranged in the box body 10, so that the integration level can be improved, and the DC power supply module is arranged outside the box body 10, so that the DC power supply module can be conveniently repaired and maintained.

The electric load can be arranged in the box body 10, and the box body 10 can provide effective protection for the electric load, so that the electric shock risk can be reduced, and the safety of personnel and equipment is ensured. The electrical load may also be located outside the housing 10, which facilitates testing and maintenance of the electrical load.

In the charging host 100 provided by the embodiment of the present application, since the conversion module 101 is electrically connected to the power distribution module 102, and the power distribution module 102 is used to connect the dc power module and the power load, the charging host 100 provided by the embodiment of the present application can charge the power load through the dc power module. Compared with the charging host 100 which can only charge the electric load through the ac power module, the charging host 100 provided in this embodiment can solve the problem of single charging mode of the charging host.

In some embodiments, with continued reference to fig. 1, the power distribution module 102 and the transformation module 101 are disposed adjacent. This arrangement can reduce the distance between the power distribution module 102 and the conversion module 101, shorten the length of the connection member for electrically connecting the power distribution module 102 and the conversion module 101, and achieve the effect of saving cost.

In some embodiments, an input portion (not shown) and an output portion (not shown) are provided on one side of the conversion module 101, and the power distribution module 102 is provided on one side of the conversion module 101 adjacent to the input portion and the output portion. Thus, the power distribution module 102 is close to the input part and the output part of the conversion module 101, so that the length of a connecting piece for electrically connecting the power distribution module 102 and the conversion module 101 can be shortened, and the effect of saving cost is achieved.

In some embodiments, the conversion module 101 includes a dc-dc conversion module 11, and the power distribution module 102 is disposed on a side of the dc-dc conversion module 11 adjacent to the input portion and the output portion. Thus, the power distribution module 102 is close to the input part and the output part of the dc-dc conversion module 11, so that the length of the connecting piece for electrically connecting the power distribution module 102 and the dc-dc conversion module 11 can be shortened, and the effect of saving the cost can be achieved.

The dc-dc conversion module 11 can convert a fixed dc voltage output by the dc power module into a variable dc voltage, and can convert an input dc voltage into a specific voltage suitable for charging of the charging host, and can provide a stable dc power for the charging host through accurate voltage adjustment, thereby being beneficial to ensuring efficient charging.

In some embodiments, the power distribution module 102 and the conversion module 101 are also used to connect an ac power module and an electrical load. The charging host 100 not only can adopt an alternating current power supply module to supply power to the electric load, but also can adopt a direct current power supply module to supply power to the electric load, so that the charging mode of the charging host is increased. In addition, an ac power module and a dc power module may be used to supply power to the electric load at the same time, so that the output power of the charging host 100 may be increased. Therefore, the present application provides a charging host 100 with high total power.

In some embodiments, with continued reference to FIG. 1, the charging host 100 further includes an AC input module 104 disposed within the housing 10, the housing 10 having a housing door, the AC input module 104 being disposed adjacent to the housing door.

The ac input module 104 is configured to receive and process an ac power input from a power grid, for example, to receive and process three-phase ac power from the power grid, and is an interface between the charging host 100 and an external power grid, and is responsible for introducing ac power from the power grid into the charging host 100, and performing preliminary pretreatment and protection, and the ac input module 104 may disconnect input of the three-phase ac power in an emergency.

The alternating current input module 104 is arranged adjacent to the box door, so that convenience in connection between the alternating current input module 104 and an external power grid is improved. The external grid may be considered an ac power module as described above.

In some embodiments, with continued reference to FIG. 1, the charging host 100 further includes a power conversion module 105 disposed within the housing 10, the power conversion module 105 being disposed on a side of the AC input module 104 remote from the housing door.

The power conversion module 105 is configured to output the dc power output by the conversion module 101 to an electric load, for example, output the dc power output by the dc-dc conversion module 11 to the electric load, and dynamically adjust the output power (including voltage and current) according to the charging state and the charging policy of the electric load, so as to ensure that the battery of the electric load can be safely and efficiently charged. Therefore, the power conversion module 105 is arranged on the side of the ac input module 104 away from the box door, so that the distance between the power conversion module 105 and the electric load can be shortened, the length of a connecting piece for electrically connecting the power conversion module 105 and the electric load can be shortened, and the effect of saving cost can be achieved.

With continued reference to fig. 1, the charging host 100 further includes a heat dissipation module 106 disposed on top of the charging host 100. The heat dissipation module 106 is beneficial to timely dissipate heat generated by the charging host 100 during operation, so that the risk of fire caused by too high temperature of the charging host 100 can be avoided.

Wherein the heat dissipation module 106 includes a heat sink 108. The heat dissipation module 106 can be used for air intake on two sides or all around, so that generated air can be prevented from blowing to a user, and better use experience is provided for the user.

Illustratively, the heat sink 108 includes a cooling fan.

In some embodiments, the charging host 100 further includes a fire protection device (not shown) disposed within the case 10. During operation of the charging host 100, fire accidents may be caused due to long-time operation of the charging host 100, current and voltage fluctuation, and environmental factor variation. Fire fighting devices (such as a fire detection system, an alarm system and a fire extinguishing system) can monitor and early warn fire risks in real time, so that fire accidents can be effectively prevented. The fire-fighting device can quickly respond to fire and start fire-extinguishing measures, so that personnel safety is guaranteed.

In some embodiments, with continued reference to FIG. 1, the charging host 100 further includes a control module 107, the control module 107 being coupled to the AC input module 104, the conversion module 101, and the power conversion module 105 and being disposed adjacent to at least one of the AC input module 104, the conversion module 101, and the power conversion module 105.

For example, as shown in fig. 1, the control module 107 is provided on a side of the power conversion module 105 away from the bottom plate P of the case 10.

The conversion module 101 may include an ac-dc conversion module 12 and a dc-dc conversion module 11. In this case, the control module 107 is connected to the ac-dc conversion module 12 and the dc-dc conversion module 11, respectively.

The control module 107 can adjust charging parameters (such as charging voltage, charging current, charging time, etc.) in real time, control input and output of the power supply, and power conversion to optimize the charging effect of the charging host 100.

When layout is performed in the case 10 of the charging host 100, the positions of the ac input module 104, the conversion module 101, the power conversion module 105, and the control module 107 have a certain flexibility, and can be adjusted arbitrarily. The ac input module 104 needs to be disposed adjacent to the conversion module 101 while ensuring that the current path is as short as possible. The ac-dc conversion module 12 and the dc-dc conversion module 11 in the conversion module 101 are disposed adjacently, and the power conversion module 105 may be disposed adjacently to the dc-dc conversion module 11. There is no strict limitation as to the specific arrangement of the modules. Possible arrangements are described with reference to fig. 2, 3, 4 and 5, although other arrangements are possible.

For example, the ac input module 104 and the ac-dc conversion module 12 are disposed adjacent to each other, the ac-dc conversion module 12 and the dc-dc conversion module 11 are disposed adjacent to each other, the dc-dc conversion module 11 is disposed adjacent to the distribution module 102, and the dc-dc conversion module 11 and the power conversion module 105 are disposed adjacent to each other. The arrangement can reduce the distance between adjacent modules, shorten the length of cables for connecting the adjacent modules, and achieve the effect of saving cost.

In the case where the dc power supply module is provided in the case 10, the dc power supply module may be provided adjacent to the conversion module 101, specifically, may be provided adjacent to the dc-dc conversion module 11.

In some embodiments, referring to fig. 1, the dc-dc conversion module 11 includes a plurality of dc-dc conversion sub-modules, where the dc-dc conversion sub-modules are independent units, and when a certain dc-dc conversion sub-module fails, other dc-dc conversion sub-modules can still work normally, so that stability and reliability of the charging host 100 are ensured. In practical applications, the number of dc-dc conversion sub-modules can be increased or decreased according to the power required to be output by the charging host 100, so as to correspondingly increase or decrease the total output power of the charging host 100.

In some embodiments, referring to fig. 1, the ac-dc conversion module 12 includes a plurality of ac-dc conversion sub-modules, and the plurality of ac-dc conversion sub-modules may enable the charging host 100 to process more charging tasks at the same time or provide higher charging power for the charging terminal, so that the charging time may be significantly shortened and the charging efficiency may be improved. Accordingly, the number of ac-dc conversion sub-modules can be increased or decreased accordingly according to the charging task or the charging power required by the charging terminal.

In some embodiments, referring to fig. 7 and 8 in combination, the conversion module 101 includes a dc-dc conversion module 11, the dc-dc conversion module 11 being electrically connected to a power distribution module 102, the dc-dc conversion module 11 and the power distribution module 102 being configured to connect a dc power module 103 to an electrical load.

Specifically, the power distribution module 102 electrically connects the dc power module 103 with the dc-dc conversion module 11, the dc-dc conversion module 11 converts a fixed dc voltage output from the dc power module 103 into a variable dc voltage, and then the dc-dc conversion module 11 is electrically connected with the power conversion module 105, and the power conversion module 105 outputs a dc power output from the dc-dc conversion module 11 to the electric load.

The direct current-direct current conversion module 11 (DCDC module) is used to further convert the input Direct Current (DC) into another direct current, and is generally used to meet the voltage and current requirements required by a specific load or battery charging. Such conversion may include boosting, buck, or voltage regulation functions to ensure a stable, proper power supply to the charging device.

Illustratively, referring to fig. 6 and 7 in combination, the output of the dc power module 103 is connected to the input of the dc-dc conversion module 11 via the power distribution module 102 to enable the dc power module 103 to power the electrical load. Compared with the charging host 100 which can only charge the electric load through the ac power module, the charging host 100 provided in this embodiment can solve the problem of single charging mode of the charging host.

In the charging main unit 100 shown in fig. 6 and 7, the dc power supply module 103 is provided outside the case 10. In other embodiments, the dc power module 103 may also be disposed in the case 10.

In some embodiments, referring to FIG. 7, the power distribution module 102 includes at least one set of first connectors L1, the at least one set of first connectors L1 being configured to connect an output of the DC power module 103 with an input of the DC-DC conversion module 11 to enable the DC power module 103 to power an electrical load. In this way, the charging host 100 can supply power to the electric load only through the dc power module 103 without an external power grid.

For example, referring to FIG. 7, the power distribution module 102 includes a set of first connectors L1. In other embodiments, the power distribution module 102 may also include two sets of first connectors L1, three sets of first connectors L1, or four sets of first connectors L1. The present embodiment is not limited thereto.

The plurality of first connecting pieces L1 connect the output end of the dc power module 103 with the input end of the dc-dc conversion module 11, so that when the first connecting piece L1 has a problem, the other first connecting pieces L1 can still ensure the continuity of electrical connection, thereby improving the reliability of the charging host 100. And the multiple sets of first connectors L1 also help to distribute the current load, reducing thermal and mechanical stresses on a single first connector L1, thereby extending the service life of the first connector L1 and charging host 100. And secondly, different combinations of the first connecting pieces L1 can be selected according to the needs to realize different current or voltage specifications, or the optimization can be carried out under different working conditions. When the first connection member L1 malfunctions, the charging main unit 100 using the plurality of sets of first connection members L1 can more easily locate and replace the malfunctioning first connection member L1 without requiring extensive disassembly or reconfiguration of the entire charging main unit 100.

For example, referring to fig. 6, the number of input ports R may be two, three, or four.

The charging host 100 provided by the embodiment of the present disclosure may be applied in a scenario of charging an electric vehicle. The input end of the charging host 100 may be connected to an external power grid, and the output end may be connected to a charging terminal.

In some embodiments, with continued reference to fig. 6, a partition T is disposed within the housing 10, with a receiving chamber Q formed between the partition T and the housing 10. The plurality of partitions T may divide the accommodating chamber Q into a plurality of chambers C, and at least one module is provided in one chamber C. The plurality of clapboards T divide the accommodating cavity Q into a plurality of bins C, so that the space of the accommodating cavity Q in the box 10 is planned, full utilization is realized, and as at least one module is independent in space, when maintenance and disassembly are carried out, the module in the bins C can be independently replaced or maintained, so that the adjacent modules cannot be blocked, and other modules are not required to be moved, thereby improving the convenience of maintenance and disassembly of the charging host 100 and reducing the maintenance difficulty and the maintenance cost of the charging host 100.

In some embodiments, referring to fig. 6, there are at least two accommodation cavities Q, and at least two accommodation cavities Q are stacked in the height direction of the case 10. Since at least two accommodation cavities Q are stacked in the height direction of the case 10, the space utilization rate of the accommodation cavities Q in the case 10 is improved, and thus the volume and the occupied area of the charging host 100 are reduced, thereby improving the integration level of the charging host 100.

For example, there are two accommodation chambers Q stacked in the height direction of the case 10. Or there may be three, four or 5 accommodating chambers Q.

In some embodiments, at least two accommodation cavities Q are stacked in the height direction of the case 10.

And secondly, different modules are respectively arranged in different accommodating cavities Q, so that the modular management is facilitated. This may not only reduce the complexity of the charging host 100, but may also improve maintainability and scalability of the charging host 100. When a module needs to be updated or serviced, it can be more easily located and accessed without disturbing other modules. Again, the separate receiving chamber Q may also provide separate heat dissipation spaces for each module, helping to achieve more efficient heat dissipation management. For example, certain modules may require special heat dissipation solutions, and their placement in different receiving cavities Q may more easily meet heat dissipation requirements. Again, each module occupies a separate housing chamber Q, which allows a certain degree of optimization of space utilization. By planning the size and layout of the accommodation chamber Q, the space within the cabinet 10 can be more effectively utilized while ensuring proper isolation between the individual modules.

The connector connects the modules in the two adjacent chambers, so that the convenience of connection between the modules is improved.

Because the ac-dc conversion module 12 is located in a chamber C, when adding the ac-dc conversion sub-module, the ac-dc conversion sub-module can be directly placed in the chamber C without moving the positions of other modules, thereby improving the convenience of adding the ac-dc conversion sub-module. Similarly, when one of the ac-dc conversion sub-modules 12 is damaged, the damaged ac-dc conversion sub-module can be directly taken out without moving the position of the other module. Therefore, the convenience of the charging host 100 to be attached and detached is improved.

In some embodiments, the dc-dc conversion module 11 is located in a chamber C, so that the charging host 100 can have better expansibility and upgradeability, and when the charging power needs to be increased or the charging speed needs to be increased, the charging host can be directly implemented by increasing the number of dc-dc conversion sub-modules, without replacing the whole charging host.

Similarly, when one of the dc-dc conversion sub-modules 101 is damaged, the damaged dc-dc conversion sub-module can be directly taken out without moving the position of the other module. Therefore, the convenience of the charging host 100 to be attached and detached is improved.

In some embodiments, the bottom of the plurality of modules is spaced from the bottom plate P. In this way, in rainy days, water on the ground can be prevented from entering the accommodating cavity Q to erode the plurality of modules, so that the charging host 100 cannot work normally.

The embodiment of the disclosure further provides a charging system 200, referring to fig. 15, including the charging host 100 described in any of the above embodiments, and an electric load, where the electric load is connected to an output port of the charging host 100.
