[0029] The beneficial effect of a hybrid energy storage power supply cabinet provided by the utility model is that: compared with the prior art, in a hybrid energy storage power supply cabinet of the utility model, a housing 2 is arranged in a cabinet 1, and an energy storage module is placed in the housing 2, and a connector 8 electrically connected to the energy storage module is arranged on the housing 2. A transmission interface 3 is arranged on the cabinet 1 for input and output of electric energy. A connecting line 4 is passed through the cabinet 1, one end of which is connected to the transmission interface 3, and the other end is connected to the positioning block 5.

[0030] In actual application, the positioning block 5 is slidably arranged on the cabinet 1, and the positioning block 5 is plugged and matched with the shell 2 to contact the connector 8 and realize the connection between the connecting line 4 and the energy storage module. In the present application, the positioning block 5 is provided to realize the positioning of the shell 2 on the one hand, and the connection between the transmission interface 3 and the energy storage module is realized after the positioning, which has a simple structure and a high degree of integration.

[0031] With the continuous maturity of distributed energy generation technology, energy storage system technology, new energy vehicles and other technologies, new energy generation, energy storage equipment, and new energy vehicles have entered people's lives. New energy generation equipment, energy storage equipment, new energy vehicle charging piles and other equipment are all independently operated, and have large volumes, requiring a large floor space, and the installation locations of each device are relatively scattered, and the equipment coordination between the devices is complex, which makes the installation and application rate of these devices have always been very low.

[0032] Energy storage mainly refers to the storage of electric energy. Energy storage itself is not an emerging technology, but from an industrial perspective it has just emerged and is in its infancy. So far, the commercial model of the energy storage industry has not yet taken shape. With the continuous advancement of my country's industrialization and urbanization, the demand for the power industry continues to grow. With the obvious acceleration of investment in new energy industries and high-tech industries, the demand for intelligent civil power distribution has increased, and the quality requirements for electric energy have become higher and higher. New energy power generation is becoming more and more popular. Nowadays, how to improve the efficiency of electricity use and maintain the stability of electric energy while maximizing benefits has become a problem of increasing concern. The interior of the conventional distribution cabinet only has a switch to control the power supply of the power grid. Once the power grid fails, all loads related to the distribution cabinet will stop working, and the normal operation of the load cannot be guaranteed, which brings a lot of inconvenience to the user's life. In addition, the electric energy generated by the new energy system is direct current, and many loads also require direct current. The traditional distribution cabinet cannot be directly connected to the new energy system, nor can it directly provide direct current output. The traditional method is to power the DC load through the "DC-AC-DC" method. This method has poor flexibility, reduces the utilization rate of electric energy, and increases the user's electricity cost.

[0033] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1, a first space and a second space are provided in the cabinet 1, and the energy storage module includes a liquid energy storage unit and a battery energy storage unit; the liquid energy storage unit is provided in the first space, and the battery energy storage unit is provided in the second space. For a more detailed description, firstly, a plurality of areas are provided in the cabinet 1, the bottom layer area is the first space, the second space is located in the middle, and the top layer is used to install and fix the rectifier, etc. The energy storage module includes two types, one type is a liquid energy storage unit, and the other type is a battery energy storage unit. Among them, the battery energy storage unit is a lithium battery energy storage unit. The first space and the second space are divided by a partition 6, and after the cabinet door is closed, the first space and the second space are both in a relatively closed environment.

[0034] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 A rectifier is installed inside the cabinet 1, and the rectifier is electrically connected between the transmission interface 3 and the connecting line 4. The energy storage module includes two types, and the transmission interface 3 includes a DC input and output interface and an AC input and output interface. By installing the rectifier, suitable electric energy can be transmitted and stored in the corresponding battery unit. The rectifier is relatively small in mass and is usually installed above the second space.

[0035] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2 , the two opposite side walls of the shell 2 are provided with card slots, which are plugged into the positioning block 5. The main purpose of the present application is to ensure the effective positioning of the liquid storage unit in the shell 2 while realizing the connection between the connecting line 4 and the transmission interface 3 by setting the positioning block 5 and other components. First of all, in order to achieve the effective cooperation between the shell 2 and the positioning block 5, card slots are provided on the two opposite side walls of the shell 2. When the shell 2 is placed at a specified position in the cabinet 1, the positioning block 5 can be moved so that the positioning block 5 can be plugged into the card slot in the shell 2.

[0036] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2 , the positioning block 5 is slidably matched with the side wall of the cabinet 1. One side of the positioning block 5 needs to be snap-fitted with the shell 2, and the other side needs to ensure stability relative to the cabinet 1. However, it should be pointed out that the positioning block 5 needs to slide relative to the cabinet 1. It is based on the above reasons that the positioning block 5 is slidably set on the side wall of the cabinet 1. When the positioning block 5 slides into the shell 2, the positioning block 5 is limited on the card slot and the cabinet 1.

[0037] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2, a limiting sleeve is fixed on the inner wall of the cabinet 1, and the limiting sleeve is slidably matched with the positioning block 5. For more detailed description, a limiting sleeve is provided on the inner wall of the cabinet 1, and the positioning block 5 can be slidably matched with the limiting sleeve due to the existence of the limiting sleeve, and the positioning block 5 has only a degree of movement along the axial direction of the limiting sleeve due to the limiting sleeve's limiting effect on the positioning block 5, which can ensure the stable clamping of the positioning block 5 and the housing 2.

[0038] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2 The limiting sleeve and the positioning block 5 are integrally formed. By the integrally formed setting, the connection between the limiting sleeve and the cabinet 1 can be ensured to be tight and reliable, thereby avoiding a series of problems such as cracks between the limiting sleeve and the positioning block 5 to a certain extent.

[0039] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2 , a partition 6 is provided on the side of the limiting sleeve away from the shell 2. The cabinet 1 needs to be in a relatively closed environment, but at the same time, an external force is required to drive the positioning block 5 to move, so that the positioning block 5 can move relative to the cabinet 1, and finally complete the positioning of the shell 2 so that the positioning block 5 and the card slot in the shell 2 are effectively matched. The partition 6 is also detachably connected to the cabinet 1. When the positioning block 5 needs to be moved, the partition 6 is removed from the cabinet 1 and the positioning block 5 is pulled to complete the installation of the shell 2. After the positioning of the shell 2 is completed, the partition 6 is reinstalled on the cabinet 1 to achieve the sealing of the cabinet 1.

[0040] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2 An elastic member 7 is provided between the positioning block 5 and the inner wall of the cabinet 1. In order to prevent the positioning block 5 from slipping out of the housing 2, an elastic member 7 is connected between the positioning block 5 and the cabinet 1. The elastic member 7 is a spring, one end of which is connected to the cabinet 1, and the other end is connected to the positioning block 5. Under the action of the elastic force of the elastic member 7, the positioning block 5 can always be pressed against the slot on the housing 2, avoiding the risk of the positioning block 5 slipping out of the slot.

[0041] In some embodiments of a hybrid energy storage power supply cabinet provided in this application, please refer to Figure 1 and Figure 2 The connector 8 is an annular structure, which is used to fit and stick to the outside of the positioning block 5. In order to ensure that the positioning block 5 stably transmits electric energy to the energy storage module, firstly, the connector 8 itself is an annular structure, and the connector 8 can be regarded as a fixed sleeve. After the positioning block 5 is inserted into the fixed sleeve, it can effectively fit with the fixed sleeve. Through the above settings, the reliability of the connection between the two is guaranteed.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
