DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention 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 invention and are not used to limit the present invention.

[0016] It should be noted that although the functional modules are divided in the device schematic and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0017] Figure 1 This is a schematic diagram of the structure of an energy storage converter energy-saving aging device provided by an embodiment of the present invention. Figure 1 The energy storage converter energy-saving aging device specifically includes but is not limited to: A first energy storage converter group and a second energy storage converter group; The AC side of the first energy storage converter group and the AC side of the second energy storage converter group are connected in parallel, and the DC side of the first energy storage converter group and the DC side of the second energy storage converter group are connected in parallel.

[0018] It can be seen that by connecting the AC side of the first energy storage converter group and the AC side of the second energy storage converter group in parallel, and connecting the DC side of the first energy storage converter group and the DC side of the second energy storage converter group in parallel, a simplified connection between the first energy storage converter group and the second energy storage converter group is achieved, which not only ensures that the two are stably connected in a multi-machine situation, but also does not need to introduce additional related circuits for setting, thereby reducing the overall circuit configuration cost, wherein, Figure 1 The "A" and "B" shown in the figure represent the corresponding different sides. When "A" is the AC side, "B" is the DC side. Conversely, when "A" is the DC side, "B" is the AC side.

[0019] It should be noted that the "AC side" of this embodiment refers to the side that transmits AC signals in the switching power supply circuit, and the frequency and direction of the AC signal will change rapidly, resulting in its characteristics and amplitude constantly changing. For example, in actual applications, the AC side can be used but not limited to transmitting audio signals, video signals, and modulated signals, etc. The specific relevant circuit structure, relevant parameter selection, etc. can be set accordingly by technical personnel in this field according to the actual application scenario. This is not the main invention point of the present invention and will not be elaborated here. The same applies to the "DC side".

[0020] In one embodiment, if Figure 2 As shown, the energy storage inverter energy-saving aging device also includes an AC source for inputting AC voltage, and the AC side of the first energy storage inverter group and the AC side of the second energy storage inverter group are simultaneously connected to the output end of the AC source. In this case, the AC source is mainly used to provide the required part of the operating power for the first energy storage inverter group and the second energy storage inverter group.

[0021] In one embodiment, if Figure 3As shown, the energy storage inverter energy-saving aging device also includes a DC source for inputting a DC voltage, and the DC side of the first energy storage inverter group and the DC side of the second energy storage inverter group are simultaneously connected to the output end of the DC source. In this case, the DC source is mainly used to provide the required partial operating power for the first energy storage inverter group and the second energy storage inverter group.

[0022] In one embodiment, the first energy storage inverter group includes at least two first energy storage inverters, the AC sides of all the first energy storage inverters are connected in parallel, and the DC sides of all the first energy storage inverters are connected in parallel; the second energy storage inverter group includes at least two second energy storage inverters, the AC sides of all the second energy storage inverters are connected in parallel, and the DC sides of all the second energy storage inverters are connected in parallel; in other words, the first energy storage inverter group and the second energy storage inverter group can each be provided with a corresponding number of energy storage inverters, and their internal connection mode is the same as that between the first energy storage inverter group and the second energy storage inverter group as a whole. The connection method is similar, and the AC side is connected in parallel and the DC side is connected in parallel. However, there is no specific limit on the number of the first energy storage converter or the second energy storage converter, and the corresponding configuration can be performed according to the actual application scenario. For example, if the first energy storage converter is set to two, then the AC sides of the two first energy storage converters are connected in parallel and the DC sides are connected in parallel; if the second energy storage converter is set to four, then the AC sides of the four second energy storage converters are connected in parallel and the DC sides are connected in parallel; in particular, if the first energy storage converter and the second energy storage converter are both set to one, then similar to Figure 2 or Figure 3 The energy storage converter energy-saving aging device shown in will not be described in detail here.

[0023] It should be noted that the number of energy storage converters in each energy storage converter group can be set arbitrarily, and the difference in the number of settings only affects the specific power allocated to each energy storage converter.

[0024] The energy storage converter energy-saving and aging device and application scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention, and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention. Those skilled in the art can know that with the evolution of the energy storage converter energy-saving and aging device and the emergence of new application scenarios, the technical solutions provided by the embodiments of the present invention are also applicable to similar technical problems.

[0025] It can be understood by those skilled in the art that Figures 1 to 3 The energy storage converter energy-saving aging device shown does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0026] Based on the specific structure of the energy storage converter energy-saving aging device described above, various embodiments of the aging control method of the present invention are proposed below.

[0027] Figure 4 This is a flow chart of an aging control method for an energy storage converter energy-saving aging device provided by an embodiment of the present invention. The aging control method can be but is not limited to being applied to Figures 1 to 3 Any energy storage converter energy-saving aging device shown in Figure 4 As shown, it specifically includes but is not limited to step S1000.

[0028] Step S1000: Within a preset aging period, the charge and discharge state of the first energy storage converter group and the charge and discharge state of the second energy storage converter group are set to be opposite.

[0029] In this step, within the preset aging cycle, the charge and discharge state of the first energy storage inverter group and the charge and discharge state of the second energy storage inverter group are set to be opposite, so that both can complete the complete charging and discharging work inside the energy storage inverter energy-saving aging device within the preset aging cycle without introducing too much external power, thereby achieving the purpose of high energy saving, wherein the preset aging cycle is reflected as the minimum operating time required for the energy storage inverter energy-saving aging device to complete a complete charging and discharging work, and the operating time can be adjusted accordingly with the energy storage inverter energy-saving aging device under different circumstances, and is not limited here.

[0030] One embodiment of the present invention, as Figure 5 As shown, when the energy storage converter energy-saving aging device further includes an AC source for inputting an AC voltage, step S1000 may include but is not limited to step S1100.

[0031] Step S1100: When the charge and discharge state of one of the first energy storage converter group and the second energy storage converter group is set to the grid-connected charging mode or the grid-connected discharging mode, the charge and discharge state of the remaining one of the first energy storage converter group and the second energy storage converter group is correspondingly set to the grid-connected discharging mode or the grid-connected charging mode.

[0032] Specifically, Figure 2As shown, the AC side of the first energy storage converter group and the AC side of the second energy storage converter group are connected in parallel to the "a" connection point of the AC source, and the DC sides are connected in parallel to the "b" connection point. In the actual operation process, the first energy storage converter group can be set to the grid-connected charging mode, but is not limited to outputting a stable DC voltage as the DC power supply of the second energy storage converter group, and the second energy storage converter group is set to the grid-connected discharging mode. At this time, since the current direction in the first energy storage converter group is a→b (① path), the second energy storage converter group The current direction in the converter group is b→a (② path), so a stable clockwise current loop is formed between the first energy storage converter group and the second energy storage converter group; when the preset operation time is reached, the power supplies of the first energy storage converter group and the second energy storage converter group are turned off, and the second energy storage converter group is set to the grid-connected charging mode, thereby outputting a stable DC voltage as the DC power supply of the first energy storage converter group, and at the same time setting the first energy storage converter group to the grid-connected discharging mode. At this time, since the current direction of the first energy storage converter group is b →a, the current direction in the second energy storage converter group is a→b, so a stable counterclockwise current loop is formed between the first energy storage converter group and the second energy storage converter group; in summary, within such a preset aging cycle, the entire first energy storage converter group and the second energy storage converter group can complete a complete charging and discharging operation (i.e. aging); it can be seen that in the entire working process, the AC source only needs to provide the power loss part during the operation of the device to ensure the stable operation of the energy storage converter energy-saving aging device, so the operation of the entire device does not require too much external power injection, thereby achieving the purpose of high energy saving. Assuming that the efficiency of a 100KW first energy storage converter group is 98%, the power dissipated during operation is: 100KW*98%=2KW; if the second energy storage converter group has the same specifications as the first energy storage converter group, then according to the aging of two 100KW energy storage converter groups, the AC source only needs to provide 2*2KW=4KW of power to ensure the stable operation of the entire device, that is, to achieve the purpose of high energy saving.

[0033] One embodiment of the present invention, as Figure 6 As shown, when the energy storage converter energy-saving aging device further includes a DC source for inputting a DC voltage, step S1000 may include but is not limited to step S1200.

[0034] Step S1200: When the charge and discharge state of one of the first energy storage converter group and the second energy storage converter group is set to the grid-connected charging mode or the off-grid discharging mode, the charge and discharge state of the remaining one of the first energy storage converter group and the second energy storage converter group is correspondingly set to the off-grid discharging mode or the grid-connected charging mode.

[0035] Specifically, Figure 3As shown, the DC side of the first energy storage inverter group and the DC side of the second energy storage inverter group are connected in parallel to the "c" connection point of the DC source, and the AC sides are connected in parallel to the "d" connection point. In the actual operation process, the first energy storage inverter group can be set to an off-grid discharge mode, but is not limited to outputting a stable AC voltage as the AC power supply of the second energy storage inverter group, and the second energy storage inverter group is set to a grid-connected charging mode. At this time, since the current direction in the first energy storage inverter group is c→d (③ path), and the current direction in the second energy storage inverter group is d→c (④ path), a stable clockwise current loop is formed between the first energy storage inverter group and the second energy storage inverter group; when the preset operation time is reached, the power supplies of the first energy storage inverter group and the second energy storage inverter group are turned off, and the second energy storage inverter group is set to Off-grid discharge mode, thereby outputting a stable AC voltage as the AC power supply of the first energy storage inverter group, and at the same time setting the first energy storage inverter group to the grid-connected charging mode. At this time, since the current direction of the second energy storage inverter group is c→d and the current direction in the first energy storage inverter group is d→c, a stable counterclockwise current loop is formed between the first energy storage inverter group and the second energy storage inverter group; in summary, within such a preset aging cycle, the entire first energy storage inverter group and the second energy storage inverter group can complete a complete charging and discharging operation (i.e. aging); it can be seen that during the entire working process, the AC source only needs to provide the power loss part during the operation of the device to ensure the stable operation of the energy storage inverter energy-saving aging device, so the operation of the entire device does not require too much external power injection, thereby achieving the purpose of high energy saving.
