Description

Technical Field

[0001] This application relates to the field of energy storage cabinet technology, and in particular to an energy storage cabinet and an energy storage device. Background Technology

[0002] An energy storage cabinet is a type of cabinet used to store battery modules and battery management components. Battery modules are the core component of the cabinet, and common battery types include lithium-ion batteries, lead-acid batteries, and flow batteries. Lithium-ion batteries are widely used in energy storage cabinets due to their advantages such as high energy density, long cycle life, and low self-discharge rate. The battery management component is responsible for real-time monitoring and management of the battery module's status, including monitoring parameters such as voltage, current, and temperature, as well as functions such as charge / discharge control, equalization management, fault diagnosis, and protection.

[0003] Currently, it is difficult to control the temperature of the internal battery modules during the operation of energy storage cabinets. When the battery modules are in a low-temperature environment in winter, the chemical reaction rate of the battery modules slows down, and the structure of the electrode materials may change, leading to faster capacity decay of the battery modules. In addition, the battery modules generate a lot of heat during charging and discharging in summer, which can cause the internal temperature to be too high, affecting the performance and lifespan of the battery modules. Consequently, it is impossible to ensure that the battery modules inside the energy storage cabinet operate at a suitable temperature. Therefore, to solve the above problems, we provide an energy storage cabinet and energy storage device. Utility Model Content

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0013] This energy storage cabinet and energy storage device, through the setting of an internal temperature sensor, can detect the internal temperature of the cabinet. At the same time, the setting of ceramic heating elements inside the heating cover can generate heat, which will raise the internal temperature of the cabinet to a suitable state, allowing the battery module to operate at an appropriate temperature. By activating the cooling fan and cooperating with the ventilation holes, cool air can pass through the battery module and battery management components to remove heat, achieving an efficient ventilation and heat dissipation effect. This ensures that the battery module temperature is maintained within a suitable range in summer, improving the performance and lifespan of the battery module. Attached Figure Description

[0021] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-4 This utility model provides a technical solution for an energy storage cabinet and an energy storage device:

[0023] An energy storage cabinet and energy storage device include a cabinet 1. Heating covers 2 are fixedly connected to both the left and right sides of the cabinet 1. A set of ceramic heating elements 3 are fixedly connected to the inner walls of both heating covers 2. A battery module 4 is fixedly installed on the inner bottom wall of the cabinet 1. A support plate 5 is fixedly connected to the inner wall of the cabinet 1. A battery management component 6 is fixedly installed on the upper surface of the support plate 5. A heat dissipation cover 10 is fixedly embedded in the back of the cabinet 1. A cooling fan 12 is fixedly installed on the inner wall of the heat dissipation cover 10. A temperature sensor 13 is fixedly installed on the inner side wall of the cabinet 1. Ventilation holes 9 are provided on both the left and right sides of the cabinet 1. The upper surface of the support plate 5... Two sets of heat dissipation ducts 20 are provided. The cabinet 1 serves as the outer shell of the entire device, protecting the internal components. The heating cover 2 and the internal ceramic heating element 3 are used to raise the temperature inside the cabinet 1 in low-temperature environments to ensure the performance of the battery module 4. The battery module 4 is the core component of energy storage, responsible for storing and releasing electrical energy. The heat dissipation cover 10 and the cooling fan 12 together form an important part of the heat dissipation system, used to expel heat from inside the cabinet 1. When the cooling fan 12 is working, it generates suction to expel hot air through the heat dissipation cover 10. The temperature sensor 13 monitors the temperature inside the cabinet 1 in real time, providing data for subsequent temperature control.

[0024] In this embodiment, electric slides 7 are fixedly embedded on both the left and right sides of the cabinet 1. Each of the output ends of the two electric slides 7 is fixedly fitted with a baffle 8. The sides of the two baffles 8 that are close to each other contact the ends of the two ventilation holes 9 that are far apart. A cover plate 16 is fixedly installed on the front of the cabinet 1. A control panel 17 is fixedly embedded on the front of the cover plate 16. An energy storage socket 18 is fixedly embedded on the front of the cover plate 16. A temperature sensor 13 is electrically connected to the control panel 17 via wires. The control panel 17 is electrically connected to the cooling fan 12, the ceramic heating element 3, and the electric slides 7 via wires. Specifically, the electric slides 7 and the baffles 8 form the opening and closing control structure for the ventilation holes 9, which can protect the interior of the ventilation holes 9. The cover plate 16 protects the front of the cabinet 1, preventing internal components from being exposed. The control panel 17 allows operators to monitor the operating status inside the cabinet 1, such as temperature information, and can also control the ceramic heating element 3, the cooling fan 12, and the electric slides 7. The energy storage socket 18 is used to connect external electrical equipment, enabling the energy storage device to supply power to external devices.

[0025] In this embodiment, a heat dissipation mesh plate 11 is fixedly connected to the inner wall of the heat dissipation cover 10, and a ventilation mesh plate 15 is fixedly connected to the inner wall of each of the two ventilation holes 9. Two sets of reinforcing uprights 14 are fixedly connected to the inner side wall of the cabinet 1, and two sets of bases 19 are fixedly connected to the bottom surface of the cabinet 1. Specifically, both the heat dissipation mesh plate 11 and the ventilation mesh plate 15 serve a protective function. The heat dissipation mesh plate 11 prevents foreign objects from entering the cabinet 1 through the heat dissipation cover 10 and damaging the cooling fan 12 or other components. The ventilation mesh plate 15 prevents foreign objects from entering the cabinet 1 through the ventilation holes 9, ensuring the normal operation of the internal components. The reinforcing uprights 14 enhance the structural strength of the cabinet 1, making the cabinet 1 more stable during transportation and use.

[0026] Working principle: First, the temperature sensor 13 detects the temperature of the cabinet 1. In low-temperature winter environments, the ceramic heating element 3 is activated via the control panel 17, which generates heat to gradually increase the internal temperature of the cabinet 1, ensuring that the battery module 4 operates at a suitable temperature. In summer, when the battery module 4 generates a large amount of heat during charging and discharging, the cooling fan 12 is activated. On the other hand, the electric slide 7 is activated to move the baffle 8, opening the ventilation hole 9. The cooling fan 12 generates suction, and cold air from outside enters the cabinet 1 through the ventilation hole 9. The cold air passes through the battery module 4 and the battery management component 6, carrying away the heat. Then, the hot air is discharged from the cabinet 1 through the heat sink 10, ensuring that the temperature of the battery module 4 is maintained within a suitable range.

[0027] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
