Description

Technical Field

[0001] This utility model relates to the field of battery energy storage technology, specifically to a testing platform. Background Technology

[0002] During the operation of a battery energy storage system, the batteries within the system generate significant heat, causing their temperature to rise continuously. This leads to accelerated aging of the lithium batteries and, in severe cases, thermal runaway. Some existing energy storage battery systems utilize a submerged liquid-cooled energy storage system, placing multiple battery modules within a single enclosure filled with coolant. This system achieves temperature control of the batteries through immersion liquid cooling.

[0003] In immersion liquid-cooled energy storage systems, factors such as the battery module model, coolant ratio, coolant inlet and outlet locations, coolant flow rate, initial coolant temperature, and internal pressure all affect the system's temperature control efficiency. During the development of immersion liquid-cooled energy storage systems, these factors need to be continuously adjusted to obtain a system with high cooling efficiency. Manufacturing a finished immersion liquid-cooled energy storage system for each different battery module model and coolant ratio, and then testing its overall performance, would be prohibitively expensive.

[0004] Therefore, in the research and development of immersion liquid-cooled energy storage systems, a testing platform is needed to simulate the environment inside the enclosure so that staff can frequently adjust the above factors and obtain immersion liquid-cooled energy storage systems with high cooling efficiency.

[0043] Please see Figures 1-3 As shown, the test platform includes a housing 1, a top cover 2, and heat exchange pipes 3. The housing 1 is a hollow structure with an open top, and its inner cavity is suitable for holding coolant. The top cover 2 is detachably connected to the upper opening of the housing 1, meaning the top cover 2 is suitable for sealing the inner cavity of the housing 1. The top cover 2 is provided with an inlet pipe 21 and an outlet pipe 22, which are respectively connected to the inner cavity of the housing 1. A circulation pump is connected between the inlet pipe 21 and the outlet pipe 22. The circulation pump is used to circulate the coolant in the housing 1 and adjust the flow rate of the coolant in the housing 1. The circulation pump, the inlet pipe 21, the outlet pipe 22, and the inner cavity of the housing 1 form a closed circulation loop. In this embodiment, a flow meter, a flow regulating valve, and a pressure gauge are sequentially installed on the inlet pipe 21. A flow regulating valve and a pressure gauge are sequentially installed on the outlet pipe 22.

[0044] The heat exchange tube 3 is disposed on the inner side wall of the housing 1, with its inlet and outlet extending outside the housing 1 for connection to a chiller outside the housing 1. The chiller and the heat exchange tube 3 work together to form a cooling cycle. The cooling cycle is used to cool the coolant inside the housing 1, thereby regulating the temperature of the coolant inside the housing 1. In this embodiment, the heat exchange tube 3 has a serpentine structure. The inner cavity of the housing 1 is rectangular. The heat exchange tube 3 is disposed on the four side walls of the inner cavity of the housing 1, forming a space for accommodating the battery module.

[0045] Please see Figures 3-4As shown, the bottom of the housing 1 has an insertion interface 11. In this embodiment, there are at least two insertion interfaces 11, arranged in a matrix. The insertion interfaces 11 are all distributed within the accommodating space enclosed by the heat exchange tubes 3. The cables of the battery module are adapted to connect to external devices of the housing 1 through the insertion interfaces 11. The devices include, but are not limited to, controllers. The controller is adapted to the output power of the battery module. A sealing groove 16 is provided at the bottom of the inner cavity of the housing 1. The sealing groove 16 is arranged around the periphery of the corresponding insertion interface 11. The sealing ring is embedded in the bottom of the inner cavity of the housing 1 through the corresponding sealing groove 16 and is arranged around the periphery of the corresponding insertion interface 11 to ensure the sealing of the inner cavity of the housing 1. A connection hole 15 for fixing the battery module is provided at the bottom of the inner cavity of the housing 1. The connection hole 15 is distributed on the inner ring of the corresponding sealing ring.

[0046] In addition, a drain port is provided at the bottom of the housing 1. A drain valve 14 is installed on the drain port, and the drain valve 15 is connected to the inner cavity of the lower shell 12. The operator can drain the coolant in the housing 1 through the drain valve 15 to replace it with a coolant of a different ratio.

[0047] A pressurization port 12 and a pressure relief valve 13 are provided on the upper middle part of the side wall of the housing 1. The pressurization port 12 and the pressure relief valve 13 are located on the outer side wall of the housing 1 and are both connected to the inner cavity of the housing 1. Operators can inject inert gas into the housing 1 through the pressurization port 12 to pressurize the inner cavity of the housing 1. In this embodiment, the pressurization port 12 is a self-sealing quick-connect interface. The inert gas is nitrogen. Operators can precisely pressurize or depressurize the inner cavity of the housing 1 according to the detection results of the pressure gauge element.

[0048] Please see Figure 1 and Figure 5 As shown, a weight-reducing groove 23 is provided at the center of the top of the top cover 2 to effectively reduce weight. A sealing protrusion is provided at the bottom of the top cover 2. The sealing protrusion is suitable for sealing the upper opening of the housing 1. The outer edge of the top cover 2 is connected to the top of the side plate of the housing 1 by bolts, and the joint surface of the two is sealed by bolt fixing and the setting of a sealing ring to ensure that the coolant does not leak when circulating in the inner cavity of the housing 1.

[0049] Furthermore, the top cover 2 has at least two liquid inlets and at least two liquid outlets. One liquid inlet is detachably connected to an inlet pipe 21 via a corresponding flange 24, so that the inlet pipe 21 communicates with the inner cavity of the housing 1. The remaining liquid inlets are detachably connected to corresponding sealing caps 25 to seal the remaining liquid inlets. One liquid outlet is detachably connected to an outlet pipe 22 via a corresponding flange 24, so that the outlet pipe 22 communicates with the inner cavity of the housing 1. The remaining liquid outlets are detachably connected to corresponding sealing caps 25 to seal the remaining liquid outlets.

[0050] In this embodiment, the top cover 2 is provided with four liquid inlets and four liquid outlets. The liquid inlets and outlets are symmetrically distributed at the left and right ends of the top cover 2 to meet the testing requirements of simulating different liquid inlet positions. Specifically, the operator can install the liquid inlet pipe 21 and liquid inlet pipe 22 on the corresponding liquid inlets and outlets according to the testing requirements of different liquid inlet positions, and the remaining liquid inlets and outlets are sealed by the sealing cap 25.

[0051] Please see Figure 2 As shown, the test platform also includes a support frame 4. The support frame 4 is located at the bottom of the housing 1 and is suitable for supporting the housing 1. In this embodiment, the support frame 4 is a frame structure, used to avoid cables connected to the connector 11 and distributed at the bottom of the housing 1. Specifically, the support frame 4 includes a frame body 43 and a reinforcing rod 44 located in the middle of the frame body 43. The bottom of the frame body 43 is provided with pulleys 41 for movement and adjustable feet 42. The pulleys 41 and feet 42 are respectively distributed at the four corners of the bottom of the frame body 43. The upper end of the feet 42 is threadedly connected to the frame body 43 by a vertically arranged screw 45. When the test platform needs to be moved, the operator rotates the screw 45 to move the feet 42 away from the ground so that the operator can move the test platform. When the test platform is moved to the designated position, the operator rotates the screw 45 to make the feet 42 contact the ground to support the housing 1.

[0052] In summary, the testing platform provided in this application effectively simulates the internal environment of a submerged liquid-cooled energy storage system by regulating the flow rate, initial temperature, and internal pressure of the coolant within the tank using a flow meter, pressure gauge, flow regulating valve, chiller, circulating pump, pressurization port, and pressure relief valve. Multiple inlets and outlets are provided on the cover to meet the testing requirements of simulating different inlet positions. This testing platform has a simple structure, is easy to operate, and effectively reduces the cost of developing submerged liquid-cooled energy storage systems.
