Description

Technical Field

[0001] The utility model belongs to the field of energy storage batteries and relates to an energy storage system that saves space. Background Technique

[0002] With the continuous increase in the scale of renewable energy power generation in China, the installed capacity of electrochemical energy storage containers has been increasing year by year. Safety is one of the key issues that must be ensured for energy storage containers, so the fire protection system is a standard configuration for currently produced electrochemical energy storage containers. After the lithium iron phosphate battery burns, a large amount of harmful substances soluble in water will be produced. Therefore, sufficient attention should be paid to the treatment of fire protection wastewater after the fire protection action is triggered. With the increasing use of more and more liquid cooling systems, the leakage of the coolant caused by the long-term reaction of the liquid cooling pipeline with the coolant or the problem of joint sealing is another hidden danger for the energy storage system to produce wastewater. For fire protection wastewater and leaked coolant, the previous energy storage systems did not collect and treat them separately, and harmful chemical substances might directly flow into rivers, lakes, seas, farmlands, or grasslands, causing environmental pollution.

[0003] In order to better collect and treat chemical wastewater, a wastewater collection device needs to be set in the energy storage system. In order to ensure the normal heat dissipation of the battery, a liquid cooling component needs to be set. Since the addition of the wastewater collection device will increase the volume of the energy storage system and cause a large floor area problem, a wastewater treatment device that saves area as much as possible is needed.

The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] A space-saving energy storage system, such as Figure 1 、 Figure 2 、 Figure 3 shown, includes a box body 1, a battery pack arranged in the box body 1, and a liquid cooling component 2 for dissipating heat from the battery pack, and the liquid cooling component 2 is also arranged in the box body 1.

[0025] As Figure 1 、 Figure 2 、 Figure 3 shown, a number of battery packs are placed in the box body 1, a number of battery compartments 13 are arranged in the box body 1, two clusters of battery PACKs are symmetrically arranged in each battery compartment 13, and each cluster of the battery PACKs is connected to a corresponding liquid cooling component 2. To ensure the safety inside the battery box body 1, a number of fire sprinklers 3 are arranged at the top of each battery compartment 13, and the fire sprinklers 3 include gas fire sprinklers 3 and liquid fire sprinklers 3 to ensure the safety inside the battery box body 1 in all directions.

[0026] Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a bottom frame is provided at the bottom of the box body 1. The bottom frame includes a number of longitudinal beams 11 and a number of cross beams 12. The longitudinal beams 11 are arranged at intervals, and the cross beams 12 are arranged at intervals along the extension direction of the longitudinal beams 11 and connected to the longitudinal beams 11. Further, three longitudinal beams 11 are provided, and the three longitudinal beams 11 are arranged at intervals. Seven cross beams 12 are provided between two adjacent longitudinal beams 11 for connection, and the seven cross beams 12 are arranged at intervals along the extension direction of the longitudinal beams 11.

[0027] The bottom frame is set to be high in the middle and low on both sides. The longitudinal beam 11 in the middle is higher than the longitudinal beams 11 on both sides. It can be set that the heights of the three longitudinal beams 11 are the same but the middle longitudinal beam 11 is raised, or it can be set that the height of the middle longitudinal beam 11 is higher than that of the longitudinal beams 11 on both sides. The bottom surfaces of the middle longitudinal beam 11 and the longitudinal beams 11 on both sides are flush, but the upper surface of the middle longitudinal beam 11 is higher than the cross beams 12 on both sides. The setting of the middle longitudinal beam 11 higher than the longitudinal beams 11 on both sides forms a slope state of the bottom frame. When coolant leaks, condensation drips, or there is a fire sprinkler in the box body 1, the liquid is guided to both sides of the box body 1. Floor drains 16 are provided on both sides of the bottom frame to facilitate the discharge of waste liquid in the box body 1 and prevent liquid accumulation.

[0028] As Figure 3 、 Figure 5 As shown, to ensure the strength of the bottom frame, the longitudinal beam 11 is set to be composed of an I-beam 111, an intermediate rib plate 112, and an H-beam 113 connected in sequence. To better ensure the strength, the I-beam 111, the intermediate rib plate 112, and the H-beam 113 are welded to ensure the strength of the box body 1 and meet the full-load lifting working conditions at the same time.

[0029] Since an intermediate rib plate 112 is provided between the I-beam 111 and the H-beam 113, a placement space 114 will be formed between the I-beam 111 and the intermediate rib plate 112, and a drainage space 115 will be formed between the H-beam 113 and the intermediate rib plate 112. The longitudinal beam 11 can not only meet the drainage requirements but also place other components, saving space. Further specifically, to save space, part of the pipelines of the liquid cooling component 2 are placed in the placement space 114. At the same time, to facilitate the arrangement of part of the pipelines of the liquid cooling component 2 in the placement space 114, the I-beam 111 is set higher than the H-beam 113, and part of the pipelines can be directly passed through the intermediate rib plate and placed in the placement space 114. Since the bottom frame is set to be high in the middle and low on both sides, the waste liquid in the box body 1 will gather to both sides until it flows into the drainage space 115 in the longitudinal beam 11. To facilitate the discharge of the waste liquid in the box body 1, a drainage plate 14 is provided in the drainage space 115. The drainage plate 14 is inclined, with the side close to the inside of the box body 1 being high and the side close to the outside of the box body 1 being low, facilitating the outflow of the waste liquid and reducing the corrosion of the longitudinal beam 11 by the waste water.

[0030] To collect the waste liquid externally, a drain pipe 15 for draining to the outside is connected to the lower end of the drainage plate 14. A ball valve is provided on the drain pipe 15. By controlling the ball valve, the waste water can be discharged more flexibly and selectively. Of course, the ball valve can also be set to any valve structure as long as it can open and close the drain pipe 15.

[0031] Since the waste liquid in the box body 1 will flow to both sides of the box body 1, in order to better make the waste liquid flow into the drainage space 115, a floor drain 16 is provided on the H-shaped steel 113 of the longitudinal beam 11. The waste liquid flows from the floor drain 16 to the drainage space 115. To facilitate the installation of the floor drain 16, the two flange plates of the H-shaped steel 113 are placed horizontally, and the middle web is set vertically. The floor drain 16 is provided on the flange plate, and the number of the floor drains 16 can be set according to needs.

[0032] To further reduce the corrosion of the bottom frame by the waste liquid, the bottom frame can be treated with hot-dip galvanized anti-corrosion.

[0033] As Figure 1 、 Figure 2 shown, the liquid cooling component 2 includes a liquid cooling unit 24, a first-stage pipeline 21 connected to the liquid cooling unit 24, a second-stage pipeline 22 connected to the first-stage pipeline 21, and a third-stage pipeline 23 connected to the second-stage pipeline 22. The first-stage pipeline 21, the second-stage pipeline 22, and the third-stage pipeline 23 form a circulating pipeline. The coolant flowing out of the liquid cooling unit 24 circulates between the first-stage pipeline 21, the second-stage pipeline 22, and the third-stage pipeline 23 to dissipate heat from the battery pack. Two clusters of battery PACKs are symmetrically arranged in each battery compartment 13, and each cluster of battery PACKs has a corresponding second-stage pipeline 22 and third-stage pipeline 23. The second-stage pipeline 22 and the third-stage pipeline 23 provide inlet and return water channels for the thermal management of the battery. The second-stage pipeline 22 and the third-stage pipeline 23 can be integrally formed or connected by quick connectors.

[0034] Part of the pipeline of the liquid cooling component 2 is arranged in the placement space 114. In this solution, the first-stage pipeline 21 is arranged in the placement space 114, saving the space of the box body 1.

[0035] Of course, the first-stage pipeline 21 can also be directly placed on the H-shaped steel 113. Since the I-shaped steel 111 is higher than the H-shaped steel 113, there is still space above the H-shaped steel 113, which is convenient for placing the first-stage pipeline 21. Directly arranging the first-stage pipeline 21 on the H-shaped steel 113 is convenient for subsequent maintenance work and saves costs.

[0036] The utility model relates to a space-saving energy storage system, which can achieve the following technical effects: a bottom frame is provided, and the bottom frame is set as a steel I-beam 111, an intermediate rib plate 112 and an H-shaped steel 113 connected in sequence. A placement space 114 is formed between the steel I-beam 111 and the intermediate rib plate 112, and the liquid cooling component 2 can be placed in the placement space 114, saving the floor area of the liquid cooling component 2 and the area of the entire energy storage system. At the same time, setting the steel I-beam 111, the intermediate rib plate 112 and the H-shaped steel 113 connected in sequence can also ensure the required structural strength and meet the requirements. The bottom frame is set with a higher middle part and lower sides on both sides, which is convenient for waste liquid to gather on both sides of the box body 1. At the same time, a drainage space 115 is formed between the H-shaped steel 113 and the intermediate rib plate 112, which is convenient for discharging the waste liquid and preventing the waste liquid from accumulating in the box body 1.

[0037] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solutions of the present utility model, and these simple modifications all belong to the protection scope of the present utility model.
