DETAILED DESCRIPTION
[0022] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.
[0023] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the composition and / or order are necessary.
[0024] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).
[0025] The energy storage device provided in the present application is applied to photovoltaic energy storage equipment installed on the balcony. The energy storage device converts solar energy into electrical energy for storage by connecting photovoltaic panels, and supplies power to the load by connecting inverters and other equipment. The energy storage device usually sets the input interface and the output interface on the left and right sides of the product. The input connection line and the output connection line can only be drawn from the left and right sides of the energy storage device. In addition, since the installation positions of the photovoltaic panels and the inverters are relatively fixed, the energy storage device can only be installed on the balcony in a fixed position. For example, in the state of the fixed installation position, the back of the energy storage device faces the fence side of the balcony, and the front faces the user. When the energy storage device needs to be shifted due to factors such as space layout, for example, the back of the energy storage device faces the wall of the building. Therefore, the input connection line and the output connection line must be bent through the top of the energy storage device to change the path. This results in messy and complicated routing, affecting the appearance of the product. At the same time, long-term bending can easily cause the input connection line and the output connection line to break, causing safety accidents.
[0026] In the present application, if the position of the photovoltaic panel connected to the input connection line and the inverter connected to the output connection line are replaced to adapt to the changed position of the energy storage device, a lot of manpower and time costs are required, and this method is usually not adopted.
[0027] In response to the above problems, the present application proposes an energy storage device, which changes the setting positions of the input connection part and the output connection part to facilitate the connection with the input connection line and the output connection line after changing the installation position of the energy storage device, so as to reduce costs.

The energy storage unit 20 is arranged inside the shell 10. The shell 10 has a front and a back. When installing the energy storage device, the front is usually facing the user for the user to operate. The input connection part 30 and the output connection part 40 are both arranged on the back of the shell 10. The input connection part 30 is used for an external input connection line 100, which can be connected to a photovoltaic panel. The output connection part 40 is used for an external output connection line 200, which can be connected to an inverter to provide electrical energy to the electrical load.
[0029] In this embodiment, the input connection part 30 is electrically connected to the input end of the energy storage unit 20, and the output connection part 40 is electrically connected to the output end of the energy storage unit 20. The energy storage unit 20 may be a storage battery, and the photovoltaic panel can convert the received solar energy into electrical energy, and convert it into chemical energy for storage through the storage battery. At the same time, the storage battery can also convert the stored chemical energy into electrical energy, and output it to the inverter through the output connection part 40, and the inverter converts it into electrical energy that meets the voltage required by the user, so as to be used by the electrical load.

The pressing plate 51 is fixed to the notch of the receiving groove 13 to cooperate with the receiving groove 13 to clamp the input connection line 100 connected to the input connection part 30 and the output connection line 200 connected to the output connection part 40.
[0039] In this embodiment, at least two receiving grooves 13 are provided on the side of the back side of the shell 10 to respectively receive the positive input connection line 101 and the negative input connection line 102 of the input connection line 100, or to respectively receive the positive output connection line 201 and the negative output connection line 202 of the output connection line 200.
