[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The present application provides an energy storage converter and an energy storage device to solve the above technical problems.

[0024] In a first aspect, the present application provides an energy storage converter, such as Figures 1 to 3 As shown, the energy storage converter includes a housing 10 and a start-up structure 20; the energy storage converter (Power Conversion System, PCS) is a controllable battery module 60 (such as Fig. 9) charging and discharging process, a device that can convert direct current and alternating current, the energy storage converter can be used in a system composed of a photovoltaic power generation device and a power grid and other power supply devices, when charging the battery module 60, the AC voltage output by the power supply device is converted into a DC voltage for charging the battery module 60; the energy storage converter can also be used when the battery module 60 supplies power to an electrical load, and the DC voltage output by the battery module 60 is converted into an AC voltage for powering the electrical load. The specific working principle of the energy storage converter has long been disclosed in the relevant technology, and this application will not repeat it.

[0025] Specifically, the housing 10 includes a main body 11 and one or two side panels 12. The side of the main body 11 is provided with a receiving groove 111 (such as Figure 4 ), the receiving groove 111 can be used to place other components of the energy storage converter; the side plate 12 is detachably arranged on the main body 11. The side plate 12 is used to open and close the receiving groove 111. Opening and closing refers to opening and closing. Here, it means that the receiving groove 111 can be opened to expose it, or the receiving groove 111 can be closed to hide it in the shell 10 through the side plate 12, thereby hiding other components located in the receiving groove 111; the shell 10 is a protective shell of the energy storage converter, and the overall shape of the shell 10 can be rectangular, square or other shapes, and this application does not make specific restrictions.

[0026] The side panel 12 is detachably connected to the main body 11 through the start structure 20. The start structure 20 includes a locking member 21 and a start member 22. The locking member 21 is disposed on the main body 11. The start member 22 is located on the inner side of the side panel 12 and connected to the side panel 12. The start member 22 is used to lock or unlock with the locking member 21. When the start member 22 is pressed in different initial situations, the start member 22 and the locking member 21 can move relative to each other, so that the start member 22 and the locking member 21 are unlocked or locked, and the side panel 12 can slide or be fixed relative to the main body 11 to open and close the receiving slot 111. It can be understood that when the starting member 22 is locked with the locking member 21, the side panel 12 can be installed and fixed on the main body 11 after sliding to a suitable position at the receiving groove 111. At this time, the side panel 12 closes the receiving groove 111; when the starting member 22 is pressed, the starting member 22 moves and separates from the locking member 212, the starting member 22 is unlocked from the locking member 21, and the side panel 12 is released from the main body 11. At this time, the side panel 12 can slide relative to the main body 11, so that the side panel 12 can be separated from the main body 11 to open the receiving groove 111.

[0027] It should be noted that the side panel 12 is installed, fixed or disassembled on the main body 11 through the starting structure 20. Specifically, the side panel 12 is disassembled on the main body 11 by sliding, which makes the disassembly and assembly of the side panel 12 smoother, and can avoid damage to the shell 10 when disassembling the side panel 12. In addition, the side panel 12 can be replaced more conveniently, which can make the assembly process of the shell 10 simpler and more convenient, and make the finished product yield and quality consistency of the shell 10 higher, thereby improving the reliability of the shell 10 and reducing the cost of the shell 10 in mass production, thereby reducing the production cost of the energy storage inverter; and since there is no need to disassemble the main body 11, the original airtightness of the main body 11 can be maintained, so that the overall airtightness of the shell 10 is always maintained good.

[0028] Specifically, see Figure 2 and Figure 3 As shown, the locking member 21 is a through hole arranged at the top of the main body 11; the starting member 22 includes a supporting portion 221 and a starting portion 222 connected to the supporting portion 221, the supporting portion 221 is connected to the side plate 12, and the starting portion 222 is located on the side of the supporting portion 221 close to the through hole. When the starting portion 222 is inserted into the through hole, the starting member 22 is locked with the locking member 21; when the starting portion 222 is pressed downward to separate the starting portion 222 from the through hole, the starting member 22 is unlocked from the locking member 21.

[0029] It can be understood that the through hole runs through the inner and outer sides of the main body 11. When the starter 222 moves upward from the inner side of the shell 10 and is inserted into the through hole, the starter 22 is locked with the locking member 21. At this time, the side panel 12 is installed and fixed on the main body 11. When the side panel 12 needs to be removed, the finger or other tools can be used to insert the through hole on the outer side of the shell 10, and the starter 222 can be pressed toward the inner side of the shell 10, so that the starter 222 moves downward to disengage from the through hole, and the starter 22 and the locking member 21 can be unlocked. At this time, the side panel 12 can be slid to remove the side panel 12. The locking and unlocking of the locking member 21 and the starter 22 are relatively convenient, making the disassembly and assembly of the side panel 12 more convenient. Among them, the starter 222, the support portion 221 and the side panel 12 can be integrally formed, and the starter 222, the support portion 221 and the side panel 12 can also be separately formed and spliced ​​by gluing, riveting, threading, welding or other methods.

[0030] For example, in one embodiment, the starter portion 222 is used to engage with the through hole to improve the connection strength between the starter portion 222 and the through hole, thereby improving the connection strength between the side plate 12 and the main body 11. In one embodiment, the starter portion 222 and the support portion 221 can be made of a material with good structural strength and elasticity, such as elastic steel, so that it is more convenient to insert the starter portion 222 into the through hole and press the starter portion 222 to separate the starter portion 222 from the through hole.

[0031] In one embodiment, the through hole can be formed by extending from the top surface of the main body 11 toward the inner side of the main body 11, the starter 22 is arranged near the top of the side plate 12, the support portion 221 extends toward the inner side of the main body 11 in a direction away from the side plate 12, and the starter 222 is located above the support portion 221, so that the starter 222 can be inserted into the through hole when the side plate 12 slides upward. In one embodiment, the side plate 12 can also be provided with a threaded hole, and a captive screw can be inserted into the threaded hole. The side plate 12 and the main body 11 are detachably connected by the captive screw to strengthen the connection strength between the side plate 12 and the main body 11. The specific role and working principle of the captive screw have been disclosed in the relevant technology, and this application will not repeat them.

[0032] Specifically, Figure 4 and Figure 5 As shown, Figure 5 It is a structural diagram of the bottom of the shell 10. A first notch 112 is provided on the bottom of the main body 11. The first notch 112 is connected to the receiving groove 111, and the side panel 12 can slide in and out of the receiving groove 111 through the first notch 112. It can be understood that when the side panel 12 needs to be removed, the starter 222 is separated from the through hole, and the side panel 12 is slid downward so that the side panel 12 slides out of the receiving groove 111 from the first notch 112, and the side panel 12 can be removed; when the side panel 12 needs to be installed, the side panel 12 is slid upward through the first notch 112, and when the top of the side panel 12 is slid to abut against the main body 11, the starter 222 is inserted into the through hole, and the side panel 12 can be installed.

[0033] It should also be noted that when removing the side panel 12, after pressing the starting portion 222 to separate the starting portion 222 from the through hole, the top end of the side panel 12 can also be pressed into the receiving groove 111, so that the top end of the side panel 12 is located in the receiving groove 111, and the bottom end of the side panel 12 is located outside the receiving groove 111. At this time, the side panel 12 is tilted as a whole, and the starting portion 222 is misaligned with the through hole. The side panel 12 is then tilted and slid downward to remove the side panel 12, which can prevent the starting portion 222 from getting stuck in the through hole again during the sliding process of the side panel 12.

[0034] See also Figures 4 to 6 As shown, in one embodiment of the present application, the main body 11 includes a rear shell 113 and a cover 114; the locking member 21 is disposed on the rear shell 113, the cover 114 is detachably connected to the rear shell 113, the cover 114 and the rear shell 113 are surrounded by a receiving groove 111, and the side plate 12 is sandwiched between the rear shell 113 and the cover 114. It should be noted that the cover 114 and the rear shell 113 are detachable, and after the cover 114 and the rear shell 113 are detached, the limit of the cover 114 on the side plate 12 is released, and at this time the side plate 12 can also slide in and out of the receiving groove 111 toward the side of the rear shell 113 where the cover 114 is located, so that the side plate 12 can have more optional disassembly and assembly methods.

[0035] Continue to see Figures 4 to 6 As shown, two opposite sides of the main body 11 are provided with a receiving groove 111, and two side panels 12 are provided, and one side panel 12 corresponds to one receiving groove 111. It can be understood that the side panels 12 on both sides of the housing 10 can be connected to the main body 11 through the starting structure 20, and the two side panels 12 can be disassembled and assembled, which can further improve the reliability of the housing 10. It should also be noted that Figure 4 Taking the side panel 12 on the left side as the first side panel and the side panel 12 on the right side as the second side panel as an example, the first side panel is connected to the main body 11 through a group of starting structures 20, and the second side panel is connected to the main body 11 through another group of starting structures 20. The structures of the two groups of starting structures 20 are the same and independent of each other. The first side panel and the second side panel are connected to the main body 11 in the same way, but the preparation materials and shapes of the first side panel and the second side panel may be the same or different.

[0036] Continue to see Figures 3 to 6 As shown, in one embodiment of the present application, the main body 11 has a housing cavity 115, and the housing cavity 115 is used to provide a housing space for components in the energy storage converter, and the housing groove 111 can be connected to or isolated from the housing cavity 115. Specifically, the energy storage converter also includes an external wiring harness 41 (such as Fig. 9 ), the external wiring harness 41 is received in the accommodating groove 111, and a wiring opening 121 for the external wiring harness 41 to pass through is provided on the side panel 12. The energy storage converter also includes a limiting plate 13. The limiting plate 13 and the inner wall of the wiring opening 121 define a wiring channel 14 for the external wiring harness 41 to pass through. The limiting plate 13 is detachably connected to the main body 11. The limiting plate 13 can be detachably connected to the main body 11 by snap-fit ​​connection, screw connection, bolt connection or other methods.

[0037] It should be noted that the external wiring harness 41 is used to electrically connect the energy storage inverter with the power supply device and the electrical load. Compared with the wiring channel 14, the wiring opening 121 has a larger area. When the external wiring harness 41 is installed, it is more convenient for the end of the external wiring harness 41 to enter and exit the receiving groove 111 through the wiring opening 121. The wiring channel 14 formed by the limiting plate 13 and the side plate 12 has a small area, and the connecting end of the external wiring harness 41 can be limited to prevent the connecting end of the external wiring harness 41 from shaking, and the limiting plate 13 can partially close the wiring opening 121 to prevent dirt or particles from entering the receiving groove 111 through the wiring opening 121; in addition, the limiting plate 13 is connected to the main body 11, and the main body 11 provides support for the limiting plate 13, and the limiting plate 13 is separable from the side plate 12, so that when the side plate 12 is removed, only the side plate 12 can be removed without removing the limiting plate 13.

[0038] It should also be noted that Figure 4Taking the perspective shown as an example, two sets of external wiring harnesses 41 can be provided, one set of external wiring harnesses 41 is received in the receiving slot 111 on the left, and the other set of external wiring harnesses 41 is received in the receiving slot 111 on the right. The external wiring harnesses 41 on the left can be used to connect the energy storage converter to the power supply device, and the external wiring harnesses 41 on the right can be used to electrically connect the energy storage converter to the electrical load. When the first side panel and the second side panel are provided at the same time, the positions and sizes of the wiring openings 121 on the first side panel and the second side panel can be the same or different, and the sizes and shapes of the limit plates 13 on the first side panel and the limit plates 13 on the second side panel can be the same or different.

[0039] In one embodiment, if Figure 7 and Figure 8 As shown, at least one of the limiting plates 13 is provided with a buckle 16 on one side away from the limiting plate 13, and the groove wall of the accommodating groove 111 is provided with a buckle 17, and the buckle 16 can be engaged with the buckle 17, which can improve the connection strength between the limiting plate 13 and the main body 11, prevent the limiting plate 13 from falling off during use, and at the same time improve the connection strength between the side plate 12 and the main body 11. Specifically, only the limiting plate 13 on the second side plate can be connected to the main body 11 through the buckle 16 and the buckle 17, or only the limiting plate 13 on the first side plate can be connected to the main body 11 through the buckle 16 and the buckle 17, or both the limiting plate 13 on the first side plate and the limiting plate 13 on the second side plate can be connected to the main body 11 through the buckle 16 and the buckle 17.

[0040] like Figure 7 As shown, in some embodiments of the present application, a heat dissipation structure 30 is provided on the back side of the main body 11, and a mounting groove 31 is provided on the heat dissipation structure 30. The energy storage converter also includes an inductor component 42, which is installed in the mounting groove 31 and connected to the main body 11. It can be understood that the back side of the main body 11 refers to the side of the back cover away from the face cover 114; the heat dissipation structure 30 is used to provide heat dissipation for the electronic components in the energy storage converter, and the heat dissipation structure 30 can be a fin structure; the inductor component 42 is the main heat-generating component in the energy storage converter, and a large amount of heat is generated when the inductor component 42 is working. The inductor component 42 is directly arranged in the heat dissipation structure 30, which can reduce the distance between the inductor component 42 and the heat dissipation structure 30, and the heat generated by the inductor component 42 can be conducted to the heat dissipation structure 30 more quickly and dissipated through the heat dissipation structure 30, thereby improving the heat dissipation efficiency of the inductor component 42.

[0041] It should also be noted that the inductor components 42 can be provided in one group or multiple groups. When multiple groups of inductor components 42 are provided, multiple mounting slots 31 are provided, and the inductor components 42 correspond to the mounting slots 31 one by one to prevent the multiple groups of inductor components 42 from affecting each other's heat dissipation.

[0042] like Figure 4 and Figure 7 As shown, in one embodiment of the present application, the energy storage converter further includes a signal transceiver 43, which is located in the accommodating cavity 115 and is arranged close to the inner wall of the accommodating cavity 115, and a notch 116 is arranged on the main body 11, which is opposite to the position of the signal transceiver 43. It can be understood that the signal transceiver 43 is a device for transmitting and receiving signals in the energy storage converter. In order to ensure the structural strength of the main body 11, the main body 11 is generally made of metal materials. The metal materials have a certain shielding effect on the signal, which will affect the normal operation of the signal transceiver 43. In this embodiment, by forming a notch 116 at a position corresponding to the signal transceiver 43 on the main body 11, the influence of the main body 11 on the signal transceiver 43 transmitting and receiving signals can be reduced.

[0043] Furthermore, the energy storage inverter also includes a protective cover 15, which is detachably connected to the main body 11. The protective cover 15 is made of non-metallic material. The protective cover 15 is used to open and close the gap 116. The protective cover 15 can be detachably connected to the main body 11 by snap connection, screw connection, bolt connection or other methods. The protective cover 15 can be made of plastic or other materials that have little effect on signal transmission. The protective cover 15 can close the gap 116 to prevent dirt or particles from entering the accommodating cavity 115 through the gap 116.

[0044] In one embodiment, the main body 11 can be die-cast as one piece; it can be understood that, compared with the related art of welding the various plates of the main body 11 together by sheet metal welding, in this embodiment, the main body 11 can be die-cast as one piece, which can improve the overall integrity and structural strength of the main body 11, and the main body 11 can be a structure formed by standard parts, the connection at each bending position of the main body 11 is more stable, the risk of connection failure of the main body 11 is lower, and the air tightness is better, so that the reliability of the main body 11 is higher.

[0045] Specifically, Fig. 9 As shown, the cover 114 may include a cover body 114a, a display screen module 114b, a glass plate 114c, a radar board 114d, a protective cover 114f and a light strip assembly 114g.

A groove is provided on the front side of the cover body 114a (i.e., the side of the cover body 114a away from the rear shell 113). The display screen module 114b, the radar board 114d, the protective cover 114f and the light strip assembly 114g are arranged in the groove. The glass plate 114c is connected to the cover body 114a, and the glass plate 114c is used to open and close the groove.

[0046] Among them, the display screen module 114b is used for display and can display the working status of the energy storage inverter; the radar board 114d can enable the energy storage inverter to have a radar function; the protective cover 114f is provided on the radar board 114d to provide protection for the radar board 114d; the light strip assembly 114g can include a plurality of lamp beads, and the light strip assembly 114g is provided on the rear side of the display screen module 114b, and the light strip assembly 114g is used to provide a light source for the display screen module 114b.

[0048] In one embodiment, the energy storage converter may further include a power connector 45 located in the receiving slot 111, and the external wiring harness 41 may electrically connect the power connector 45 to the electrical load. Figure 4 Taking the perspective shown as an example, the photovoltaic connector 441, the photovoltaic filter board 442 and the photovoltaic filter board bracket 443 are located in the accommodating groove 111 on the left, and the power connector 45 is located in the accommodating groove 111 on the right.

[0049] In one embodiment, the energy storage converter may further include a switch assembly 46 and a circuit board assembly. The switch assembly 46 is located in the receiving groove 111, and the switch assembly 46 is used to control the opening and closing of the energy storage converter; the circuit board assembly is located in the receiving cavity 115, and the circuit board assembly is used to control the operation of the energy storage converter. The circuit board assembly may include a first circuit board 471, a second circuit board 472, and a third circuit board 473. The first circuit board 471 is connected to the main body 11 through a ceramic substrate. The first circuit board 471, the second circuit board 472, and the third circuit board 473 are stacked in sequence through studs, which can make the arrangement of the circuit board assembly more compact, thereby reducing the space occupied by the circuit board assembly.
