Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage, in particular to an energy storage type charging and battery swapping cabinet. BACKGROUND

[0002] With the rapid development of new energy industry, the demand for energy storage type charging and battery swapping cabinets that are matched with it is also increasing. As the core bearing and guarantee equipment in the battery charging process, the safety performance of the energy storage type charging and battery swapping cabinet is directly related to the stability and safety of the charging process, especially the battery thermal runaway problem that may occur during battery charging, which has become a key technical bottleneck restricting the development of the energy storage type charging and battery swapping cabinet.

[0003] In the current technical field of energy storage type charging and battery swapping cabinet, in view of the thermal runaway that may occur during battery charging, the existing technology generally adopts the way of spraying cooling to cope with it. The core principle of this kind of technology is to set a spraying device inside the energy storage type charging and battery swapping cabinet, when the thermal runaway signs of the battery are detected (such as temperature rising sharply, generating smoke, etc.), the spraying device starts to spray cooling water to the battery in thermal runaway, so as to achieve the purpose of cooling.

[0004] However, through long-term practical application, it is found that the existing thermal runaway coping technology based on spraying has the problems of low cooling efficiency and unevenness. During the spraying process, the cooling water mainly covers the surface of the battery through top-down spraying, and due to the limitation of spraying angle, water pressure and the structure of the battery itself (such as the shielding of the battery shell, etc.), it is difficult for the cooling water to uniformly cover all the heating areas of the battery, especially the bottom, side and gap inside the battery pack, which is easy to form a cooling dead angle. The existence of these cooling dead angles leads to the fact that the local temperature of the battery cannot be reduced in time, which not only affects the overall cooling effect, but also may become a hidden danger point for further spread of thermal runaway.

[0044] Preferably, as shown in Figure 3 the partition plate 12 comprises a first leaf plate 121, a second leaf plate 122 and a thermal switch 123, the first leaf plate 121 and the second leaf plate 122 are rotatably installed in the box body 11, and the first leaf plate 121 and the second leaf plate 122 are locked and fixed by the thermal switch 123, when the battery is in normal charging, the thermal switch 123 locks and fixes the first leaf plate 121 and the second leaf plate 122 to bear the battery; once the battery is in thermal runaway, the thermal switch 123 is automatically unlocked after being heated, the first leaf plate 121 and the second leaf plate 122 are turned over under the action of gravity, the bottom of the battery accommodating cavity 111 is opened, and the battery falls into the water storage cavity 112 and is immersed in the cooling water, so that the battery can quickly escape from a high temperature environment and enter the cooling water for efficient cooling when the battery is in thermal runaway, and greater loss caused by heat spread is effectively avoided.

[0045] Preferably, the response temperature of the thermal switch 123 is set to be between 80 DEG C and 120 DEG C, so that the action can be triggered at the initial stage of battery thermal runaway, and rapid response and effective protection are realized.

[0046] Preferably, the first leaf plate 121 is provided with a lock tongue groove 1211, the second leaf plate 122 is provided with a mounting groove 1221, the lock tongue groove 1211 and the mounting groove 1221 are oppositely arranged, the mounting groove 1221 is used for mounting the thermal switch 123, and the thermal switch 123 cooperates with the lock tongue groove 1211 to lock and fix the first leaf plate 121 and the second leaf plate 122 or release the locking and fixing of the first leaf plate 121 and the second leaf plate 122.

[0047] Preferably, as shown in Figure 4As shown, the thermal switch 123 comprises a lock tongue 1231, a back-off spring 1232 and a tightener 1233. One end of the lock tongue 1231 is slidingly installed in the installation groove 1221, and the other end can be inserted into or withdrawn from the lock tongue groove 1211. One end of the back-off spring 1232 is fixedly connected with the lock tongue 1231, and the other end is fixedly connected with the inner wall of the installation groove 1221. The back-off spring 1232 is used to always apply an elastic pulling force to the lock tongue 1231, so that the lock tongue 1231 maintains the potential energy of being withdrawn from the lock tongue groove 1211. One end of the tightener 1233 abuts against the lock tongue 1231, and the other end abuts against the inner wall of the installation groove 1221. When the battery is normally charged, that is, the temperature in the battery accommodating cavity 111 is lower than the response temperature of the thermal switch 123, the tightener 1233 overcomes the pulling force of the back-off spring 1232 on the lock tongue 1231, so that the lock tongue 1231 is inserted into and tightly abuts against the lock tongue groove 1211, thereby locking and fixing the first leaf plate 121 and the second leaf plate 122 to bear the battery. When the battery is in thermal runaway and fire is caused, that is, the temperature in the battery accommodating cavity 111 is higher than the response temperature of the thermal switch 123, the tightener 1233 is heated and expanded and broken, so that the lock tongue 1231 loses support, and under the elastic pulling force of the back-off spring 1232, the lock tongue 1231 is quickly withdrawn from the lock tongue groove 1211, quickly releasing the locking between the first leaf plate 121 and the second leaf plate 122, and then the first leaf plate 121 and the second leaf plate 122 are turned over under the action of gravity, so that the bottom of the battery accommodating cavity 111 is opened, and the battery quickly slides into the water storage cavity 112 and is immersed in the cooling water.

Subsequently, the first leaf plate 121 and the second leaf plate 122 are turned over under the action of gravity, so that the bottom of the battery accommodating cavity 111 is opened, and the battery quickly slides into the water storage cavity 112 and is immersed in the cooling water.
