Description

Technical Field

[0001] This utility model relates to the field of home energy storage design technology, and in particular to an energy storage stacking power supply device. Background Technology

[0002] Existing energy storage stacking power supply devices are mainly used as backup power sources when the power grid is out, such as in the event of natural disasters or circuit maintenance. These devices can power basic electrical appliances in the home, such as lighting fixtures, refrigerators, and routers, ensuring that the basic life of the family is not greatly affected and maintaining a certain level of comfort and convenience.

[0003] However, it cannot flexibly increase or decrease the number of battery boxes during use, and the energy storage capacity is basically fixed after installation. When the user's power demand increases later, it is difficult to expand the energy storage device in a simple way. It may be necessary to replace the entire energy storage system, which is costly. Moreover, it is limited by the traditional wiring harness connection method. The structure is often set at the back or left and right sides of the device to accommodate the wiring harness and the sheet metal shell protection structure, resulting in a large overall size of the device and the internal space cannot be fully utilized. In environments with limited space, such as homes, it may occupy a lot of space, causing inconvenience to the user in terms of use and placement. Summary of the Invention

Through the design of the base connector, connector male and connector female, the base, battery box and control box can be easily connected to each other. The biggest advantage of this connection method is that the number of battery boxes can be flexibly increased or decreased according to actual needs, so as to realize the flexible expansion of energy storage capacity. In addition, due to the limitation of wiring harness connection, previous products often need to set the structure at the rear or left and right sides of the equipment and use sheet metal housing to protect the wiring harness. However, this device gets rid of this layout constraint. Its structural layout is more compact and reasonable, freeing up more space and improving space utilization.

[0017] Reference Figure 1-4 This utility model embodiment discloses an energy storage stacking power supply device, which includes: a base plate 6, a control box 4 and a battery box 5, each with a through hole 1, a handle 2 fixedly connected to the inner wall of the through hole 1, four casters 3 fixedly connected to the lower surface of the base plate 6, the four casters 3 being symmetrically arranged, a base connector 22 fixedly connected to the upper surface of the base plate 6, multiple battery boxes 5 movably connected to the upper surface of the base plate 6, a slave control bracket 17 fixedly connected to the inner surface of the battery box 5, a slave control device 16 fixedly connected to the inner surface of the slave control bracket 17, a battery module 15 fixedly connected to the inner surface of the battery box 5, and a series copper busbar 14 fixedly connected to the upper surface of the battery module 15.

[0018] Specifically: The battery box 5 in the device contains a battery module 15, which is the core component of energy storage. It relies on internal chemical reactions to convert electrical energy into chemical energy for storage. When there is an external power input, the current flows through the circuit to the battery module 15, where an electrochemical reaction occurs inside the battery, putting the battery in a charging state and realizing energy storage. The series copper busbar 14 connects each battery module 15 to form a complete energy storage battery pack, ensuring that the battery modules can work together to complete the energy storage task and improve the energy storage capacity and voltage level.

A support frame 21 is fixedly connected to the inner surface of multiple battery boxes 5. A connector male 20 is fixedly connected to the upper surface of the support frame 21. The connector male 20 is movably connected to the connector female 19.

[0020] Specifically: the base connector 22, the male connector 20, and the female connector 19 constitute the connection system of the device. The base connector 22 is fixed on the base plate, providing the basic connection point for the entire device. The male connector 20 is located on the support frame 21 inside the battery box 5, and the female connector 19 is located inside the cover 18 of the battery box 5 and the control box 4. When the device is assembled, the female connector 19 located inside the battery box 5 on the upper surface of the base plate 6 is movably connected to the base connector 22. Adjacent battery boxes 5 and the battery box 5 and the control box 4 are interconnected through the movable connection between the male connector 20 and the female connector 19, thus physically constructing a complete stacked structure, making the base 6, the battery box 5, and the control box 4 a whole.

[0021] Working principle: When in use, place the battery box 5 on the base plate 6, and ensure that the connector female 19 inside the battery box 5 on the upper surface of the base plate 6 is accurately mated and connected to the base connector 22, ensuring a firm connection and normal electrical and communication connection. If there are multiple battery boxes 5, stack them in sequence and connect them to each other through the connector female 19 and connector male 20. Place the control box 4 on the upper surface of the multiple battery boxes 5, and correctly connect the control box 4 with the connector male 19 and connector female 20 on the battery boxes 5 to complete the electrical and communication connection between the control box 4 and the battery box 5.
