[0047] Referring to Figures 1 to 2 , the box body 10 includes a first wall 10a and a second wall 10b that are oppositely arranged along the first direction X, a third wall 10c and a fourth wall 10d that are oppositely arranged along the second direction Y, and a fifth wall 10e and a sixth wall 10f that are oppositely arranged along the third direction Z. The first wall 10a, the third wall 10c, the second wall 10b, and the fourth wall 10d are sequentially connected end to end to form a tetrahedral structure with both ends open. The fifth wall 10e and the sixth wall 10f respectively cover the two open ends to form a closed box body 10. Referring to Figure 3 , an accommodation cavity 101 is provided inside the box body 10. Referring to Figure 3 , Figure 5 and Figure 7 , the box body 10 includes a second partition 12. The second partition 12 extends along the third direction Z and is inscribed in the box body 10. Specifically, one end of the second partition 12 along the third direction Z is connected to the fifth wall 10e, and the other end is connected to the sixth wall 10f to divide the accommodation cavity 101 into a first partition cavity 102 and a second partition cavity 103 that are spaced apart along the first direction X.
[0048] Referring to Figure 3 , Figure 7 and Figures 10 to 11 , the number of power modules 20 is multiple, and they are spaced apart and arranged in the accommodation cavity 101 of the box body 10. Specifically, as in Figure 3 and Figure 7 the illustrated embodiment, the power module 20 is arranged in the first partition cavity 102. The input end of the power module 20 can access external electric energy, and the power module 20 can convert the external electric energy into the electric energy required by the electrical device. Among them, converting the external electric energy into the electric energy required by the electrical device can be to adjust the voltage of the external electric energy or to convert alternating current into direct current.
[0049] Referring to Figures 3 to 5 and Figures 7 to 9 , the output component 30 is arranged in the accommodation cavity 101 of the box body 10. Specifically, as in Figures 3 to 5In the illustrated embodiment, the output component 30 is disposed in the second partition cavity 103. The output component 30 includes an input member 31 and an output member 32. The input end of the input member 31 is electrically connected to the output end of the power supply module 20, the output end of the input member 31 is electrically connected to the output member 32, and the output end of the output member 32 can be electrically connected to an electrical device to output the electric energy received and converted by the power supply module 20 to the electrical device, providing the required electric energy for the electrical device.
[0050] Referring to Figures 4 to 5 , the control component 40 is disposed in the accommodation cavity 101 of the box body 10. Specifically, as Figures 4 to 5 shown in the illustrated embodiment, the control component 40 is disposed in the second partition cavity 103. The control component 40 is communicatively connected to the input member 31, and the control component 40 can control the connection or disconnection between the connected input member 31 and the power supply module 20 to adjust the output power of the output member 32 for outputting electric energy to the electrical device.
[0051] When an electrical device is being charged, users usually select different charging powers according to different charging requirements. For example, fast charging requires selecting a relatively high charging power, while slow charging can select a relatively low charging power. To meet different charging requirements, the solutions of existing charging devices mainly include two types. One is to design and produce multiple charging modules with different powers and install them in the box body of the charging device to meet the charging requirements of different electrical devices for different charging powers; the other is to add an adjustment function to the charging module to adapt to the charging requirements of different charging powers. However, designing and producing multiple charging modules with different powers will increase production costs and the number of devices. The size of the box body of the charging device needs to be adapted according to the different powers of the charging modules, and the positions and structures of the internal electrical components also need to be changed, which is not conducive to mass production and maintenance, resulting in increased production and subsequent maintenance costs of the charging device.
[0052] The charging device 1 provided by the embodiments of the present application is configured by arranging a plurality of power modules 20 in the accommodation cavity 101 of the box body 10. The input ends of the power modules 20 can access external electric energy and convert the external electric energy into the electric energy required for charging an electrical device. Moreover, the powers of the plurality of power modules 20 are the same. The input end of the input component 31 in the output component 30 is electrically connected to the output end of the power module 20, the output end of the input component 31 is electrically connected to the input end of the output component 32, and the output end of the output component 32 can be electrically connected to the electrical device, so as to output the electric energy converted by the power module 20 to the electrical device to provide the required electric energy for the electrical device. The control component 40 is communicatively connected to the input component 31, and the control component 40 can control the connection or disconnection between the connected input component 31 and the power module 20, that is, the control component 40 can maintain the connection between the connected input component 31 and the power module 20, or can also disconnect the connection between the connected input component 31 and the power module 20, thereby adjusting and controlling the number of power modules 20 accessed by the input component 31 of the output component 30, and further adjusting and controlling the output power of the electric energy output to the electrical device through the output component 32, so that the charging device 1 can meet the charging requirements of the electrical device for different charging powers.
[0053] In some embodiments, the powers of the plurality of power modules 20 are the same. In some implementation manners, the power of the power module 20 is 40 KW. In some other implementation manners, the power of the power module 20 can be selected according to actual usage requirements, as long as the powers of the plurality of power modules 20 are the same. The plurality of power modules 20 adopting the same power does not require designing and manufacturing power modules with multiple different powers, reducing production costs, and the internal structure of the box body 10 does not need to be adjusted according to power modules with different powers, and is also convenient for subsequent maintenance.
[0054] In some embodiments, referring to Figure 3 、 Figure 5 and Figures 7 to 9, the input component 31 includes a relay group. The number of input components 31 is multiple, and the multiple input components 31 are arranged at intervals along the third direction Z. The number of input components 31 corresponds one-to-one to the number of power supply modules 20. The input end of one input component 31 is electrically connected to the output end of one power supply module 20. The output component 32 includes an output board. The number of output components 32 is multiple. The output components 32 extend along the third direction Z, and the multiple output components 32 are arranged at intervals along the second direction Y. The input end of each output component 32 is electrically connected to the output ends of the multiple input components 31 respectively. The output end of each output component 32 can be electrically connected to an electrical device, that is, the input end of each output board is electrically connected to the output ends of the multiple relay groups respectively, and the output end of each output board can be electrically connected to an electrical device to deliver the electric energy converted by the power supply module 20 to the electrical device and provide the required electric energy to the electrical device. The control component 40 can control the connection or disconnection between at least one input component 31 and the connected power supply module 20 to adjust and control the output power of the output component 32 for delivering electric energy to the electrical device. The input component 31 adopts a relay group, the output component 32 adopts a structure design of an output board, and the connection mode that each output component 32 is electrically connected to multiple input components 31 enables the input component 31 and the output component 32 to form a matrix relay. Furthermore, the control component 40 only needs to control the connection or disconnection between the connected input component 31 and the power supply module 20 to adjust and control the output power of the output component 32 for delivering electric energy to the electrical device, ensuring the stability and accuracy of control.
[0055] In some embodiments, referring to Figures 7 to 9 , the output component 30 further includes a communication board 33. The number of communication boards 33 is multiple. Each communication board 33 is communicatively connected to at least one input component 31. The control component 40 controls the connection or disconnection between the connected input component 31 and the power supply module 20 through the communication board 33. Specifically, in the embodiment shown in Figures 7 to 9 , the number of communication boards 33 is three, and each communication board 33 is communicatively connected to four input components 31, thereby forming a grouped control of the multiple input components 31, improving the control efficiency, and ensuring the control stability of the connection or disconnection between the connected input component 31 and the power supply module 20.
[0056] In some embodiments, referring to Figures 7 to 9 , the input component 31 includes a first input component 311 and a second input component 312. The first input component 311 and the second input component 312 are arranged at intervals along the first direction X. The first input component 311 is electrically connected to the positive extreme of the power supply module 20, and the second input component 312 is electrically connected to the negative extreme of the power supply module 20. Specifically, in Figure 8 and Figure 9In the illustrated embodiment, the number of the first input members 311 is the same as that of the second input members 312, both being 12, which is the same as the number of the power supply modules 20.
[0057] Referring to Figures 7 to 9 , the output member 32 includes a first output member 321 and a second output member 322. The first output member 321 and the second output member 322 are spaced apart along the first direction X. The input end of each first output member 321 is electrically connected to the output ends of a plurality of first input members 311 respectively. The plurality of first output members 321 and the plurality of first input members 311 cooperate to form a matrix structure. The input end of each second output member 322 is electrically connected to the output ends of a plurality of second input members 312 respectively. The plurality of second output members 322 and the plurality of second input members 312 cooperate to form a matrix structure, so that the output member 32 can collect the electric energy in the power supply modules 20 connected to each input member 31 and output the required electric energy to the electrical equipment. Specifically, as Figures 8 to 9 shown in the illustrated embodiment, the number of the first output members 321 is 8. The input end of each first output member 321 is electrically connected to the output ends of a plurality of first input members 311 respectively. The number of the second output members 322 is 8. The input end of each second output member 322 is electrically connected to the output ends of a plurality of second input members 312 respectively.
[0058] Referring to Figures 7 to 9 , each communication board 33 is communicatively connected to at least one first input member 311. The control component 40 controls the connection or disconnection between the connected first input member 311 and the power supply module 20 through the communication board 33, that is, controls the connection or disconnection between the positive electrode end of the first input member 311 and the power supply module 20, so as to control the connection or disconnection between the connected input member 31 and the power supply module 20. Specifically, as Figures 7 to 9 shown in the illustrated embodiment, each communication board 33 is communicatively connected to four first input members 311, so as to divide the 12 first input members 311 into three groups. In some other implementation manners, each communication board 33 is communicatively connected to at least one second input member 312. The control component 40 controls the connection or disconnection between the connected first input member 311 and the power supply module 20 through the communication board 33, that is, controls the connection or disconnection between the negative electrode end of the second input member 312 and the power supply module 20, so as to control the connection or disconnection between the connected input member 31 and the power supply module 20. In some other implementation manners, the number of the first input members 311 or the second input members 312 connected to each communication board 33 can be selected according to actual usage requirements.
[0059] In some embodiments, the power of each power module 20 is 40KW, so that the maximum output power of the output component 30 to output electric energy to the electrical equipment is 480KW, and the minimum output power is 40KW. The control component 40 can control the connection or disconnection between the connected input component 31 and the power module 20 through the communication board 33 according to the charging requirements of the electrical equipment, and control the output power of the output component 32 to output electric energy to the electrical equipment within the range of 40KW to 480KW.
[0060] In some embodiments, the output end of the output component 32 is electrically connected to the charging gun, and the output component 32 outputs electric energy to the electrical equipment through the charging gun.
[0061] In some embodiments, referring to Figure 7 , the box body 10 includes a plurality of first partition plates 11. The first partition plates 11 are arranged in the accommodation cavity 101. Specifically, the first partition plates 11 are arranged in the first partition cavity 102. One first partition plate 11 corresponds to one power module 20. The power module 20 is arranged on the first partition plate 11 along the third direction Z. The first partition plate 11 forms a support for the power module 20. The power module 20 can move on the first partition plate 11 along the length direction of the first partition plate 11, so that the power module 20 can be withdrawn from the box body 10 to disconnect the electrical connection with the connected input component 31. Specifically, as shown in the embodiment of Figure 7 , the first partition plate 11 extends along the second direction Y. That is, the length direction of the first partition plate 11 is parallel to the second direction Y. The power module 20 moves on the first partition plate 11 along the second direction Y so that the power module 20 can be withdrawn from the first partition plate 11, and then withdrawn from the box body 10, and the electrical connection with the connected input component 31 is disconnected, thereby reducing the output power of the output component 32 to output electric energy to the electrical equipment. On the contrary, loading the power module 20 on the vacant first partition plate 11 and electrically connecting it to the input component 31 can increase the output power of the output component 32 to output electric energy to the electrical equipment. Therefore, by adjusting the number of power modules 20 in the box body 10, the output power of the output component 32 to output electric energy to the electrical equipment is adjusted. Moreover, the cooperative design of the power module 20 and the first partition plate 11 facilitates the maintenance of the power module 20.
[0062] In some embodiments, referring to Figure 7 , limiting parts 111 are respectively arranged on the opposite sides of the first partition plate 11 along the first direction X.
