Technical Field

[0001] The utility model belongs to the field of energy storage containers, and in particular relates to an electric-liquid separation type energy storage container. Background Art

[0002] With the development of new energy technologies, energy storage containers, as highly integrated energy storage devices, have been increasingly widely used.

[0003] The energy storage container is mainly composed of a battery compartment, an equipment compartment, and a temperature control compartment. Currently, air cooling and liquid cooling are more widely used in the market. Air cooling is to exchange air heat with the surrounding air of the battery through the air conditioner, fan, and air duct in the temperature control compartment to achieve the purpose of heat dissipation; liquid cooling is to achieve heat contact and heating with the battery through liquid cooling units, liquid cooling pipelines, water cooling plates, etc.

Once water leakage occurs, it is very easy to cause damage to electrical components. The above phenomena make the energy storage containers have safety hazards during use. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An electric-liquid separation energy storage container, having a battery compartment, is characterized by comprising:

[0008] A battery pack accommodating plate rack is horizontally arranged in the battery compartment, and the battery pack accommodating plate rack has multiple battery pack accommodating positions; multiple liquid-cooled battery packs are correspondingly accommodated in the multiple battery pack accommodating positions, the liquid-cooled battery pack has a water inlet and a water outlet, a water pipe structure has a water inlet branch pipe and a water outlet branch pipe, a water resistance baffle is arranged between the battery pack accommodating plate rack and the water pipe structure, and the water inlet branch pipe and the water outlet branch pipe pass through the water resistance baffle and are connected with the water inlet and the water outlet respectively.

[0009] Preferably, one end of the liquid-cooled battery pack is detachably disposed on the battery pack accommodating plate frame, and the other opposite end is disposed on the water resistance partition plate.

[0010] Furthermore, the battery pack accommodating plate rack includes a plurality of vertical frame structures and a plurality of partitions horizontally arranged on the frame structures, and the battery pack accommodating plate rack forms a plurality of battery pack accommodating positions distributed in a matrix on a vertical plane through the plurality of frame structures and the corresponding plurality of partitions, and the liquid-cooled battery packs are correspondingly arranged on the partitions, and the plurality of battery pack accommodating positions arranged along the vertical direction are used as battery pack positions, and the plurality of battery pack accommodating positions arranged along the horizontal direction are used as battery pack positions.

[0011] Furthermore, the side of the battery pack containing plate frame away from the water resistance partition is used as the power connection side, and the liquid-cooled battery pack is connected through the surface of the frame structure on the power connection side and the side of the partition.

[0012] Furthermore, the liquid-cooled battery pack has a power connection terminal and a water inlet terminal. The power connection terminal is detachably arranged on the power connection side, the water inlet terminal is connected to the water pipe structure, and the water inlet terminal also has a fire inlet.

[0013] Furthermore, the water pipe structure also includes multiple inlet pipes and multiple outlet pipes, and the multiple inlet pipes and the multiple outlet pipes are all horizontally arranged, and the multiple inlet pipes and the multiple outlet pipes correspond one-to-one with the multiple battery pack positions in the vertical direction, the inlet pipe has multiple inlet branches, and the outlet pipe has multiple outlet branches, and the multiple inlet branches and the multiple outlet branches are connected one-to-one with the multiple liquid-cooled battery packs of the corresponding battery pack positions.

[0015] Preferably, the utility model also has a pair of side doors that can be opened and closed, and the battery pack accommodating plate rack and the water pipe structure are respectively located near the pair of side doors.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Because the electric-liquid separation energy storage container of the utility model includes a battery pack accommodating plate frame, multiple liquid-cooled battery packs, a water pipe structure and a water resistance baffle, the battery pack accommodating plate frame has multiple battery pack accommodating positions; multiple liquid-cooled battery packs are correspondingly accommodated in the multiple battery pack accommodating positions, the liquid-cooled battery pack has a water inlet and a water outlet, the water pipe structure has a water inlet branch pipe and a water outlet branch pipe, the water resistance baffle is arranged between the battery pack accommodating plate frame and the water pipe structure, and the water inlet branch pipe and the water outlet branch pipe pass through the water resistance baffle and are connected with the water inlet and the water outlet respectively. Therefore, the utility model realizes physical isolation of waterways and circuits through the water resistance baffle, thereby avoiding the adverse effects of water on electricity, and significantly reducing the safety hazards of the energy storage container during use.

[0018] 2. Since one end of the liquid-cooled battery pack of the present utility model is detachably arranged on the battery pack accommodation plate rack, and the opposite end is arranged on the water resistance partition plate, therefore, the present utility model greatly improves the installation strength of the liquid-cooled battery pack through fixing at both ends, thereby having higher anti-impact performance.

[0019] 3. Since one side of the battery pack accommodation plate rack far from the water resistance partition plate of the present utility model is used as the power connection side, and the liquid-cooled battery pack realizes wiring through the surface of the rack structure and the side surface of the partition plate on the power connection side, therefore, in the present utility model, the power connection side for the electrical wiring of the liquid-cooled battery pack is far from the water resistance partition plate, thereby further strengthening the isolation of the water circuit and the circuit of the liquid-cooled battery pack.

[0020] 4. Since the water pipe structure of the present utility model further includes a plurality of inlet water pipes and a plurality of outlet water pipes, the plurality of inlet water pipes and the plurality of outlet water pipes are all horizontally arranged, and the plurality of inlet water pipes and the plurality of outlet water pipes correspond to a plurality of battery pack rows one by one in the vertical direction. The inlet water pipe has a plurality of inlet branch pipes, the outlet water pipe has a plurality of outlet branch pipes, and the plurality of inlet branch pipes and the plurality of outlet branch pipes are in one-to-one correspondence and communication with a plurality of liquid-cooled battery packs in the corresponding battery pack rows. Therefore, for the same inlet water pipe or the same outlet water pipe of the present invention, without the influence of gravitational potential energy, the balance of the water flow velocity can be achieved, and the water flow velocity is directly related to the heat dissipation of the liquid-cooled battery pack. Thus, the heat dissipation speeds of the liquid-cooled battery packs in the same battery pack row are roughly the same, which is convenient for troubleshooting when the working areas are at the same potential surface.

[0021] 5. Since the present utility model further has a pair of side doors that can be opened and closed, and the battery pack accommodation plate rack and the water pipe structure are respectively located near the pair of side doors, therefore, the present utility model is convenient for the operation of the water pipe structure and the setting and wiring operations of the liquid-cooled battery pack.

[0036] The multiple battery accommodation positions arranged in the vertical direction are used as the battery pack columns 11B, and the multiple battery accommodation positions arranged in the horizontal direction are used as the battery pack rows 11A.

[0037] As Figure 6 and Figure 7 shown, the number of the liquid-cooled battery packs 20 is multiple, and they are correspondingly inserted and arranged on the partition plates, so that the multiple liquid-cooled battery packs 20 are correspondingly accommodated in the multiple battery accommodation positions, and the liquid-cooled battery packs 20 realize electrical wiring through the surfaces of the frame structures 11 on the power connection side 10A and the side surfaces of the partition plates.

[0038] The liquid-cooled battery pack 20 has a water inlet 21 and a water outlet 22.
