Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically a battery module performance testing device. Background Technology

[0002] In the production and manufacturing process of new energy power batteries, it is necessary to conduct environmental temperature tests on the integrated battery pack and thermal management system to ensure the relevant performance of the integrated battery module.

[0003] Currently, commercially available equipment for battery module performance testing typically employs an environmental chamber. During battery module testing, a temperature control unit inside the environmental chamber circulates high-temperature or low-temperature airflow to simulate high-temperature and low-temperature environments. Simultaneously, an external water chiller is connected to the battery module so that during charging and discharging, the water chiller injects heat exchange medium into the battery module's thermal management system to regulate its temperature. However, currently, environmental chambers and water chillers are independent units. They need to be used in conjunction during battery module performance testing. When an external water chiller is connected to the battery module via pipes, the presence of these pipes not only leads to a chaotic piping system but also prevents effective sealing of the environmental chamber, ultimately affecting the accuracy of the test results.

[0004] In addition, after the battery module testing is completed, the pipes on the water chiller need to be pulled out of the battery module. During the process of pulling out the pipes, since the battery module is placed horizontally on the bottom wall of the environmental chamber, the cooling water or other cooling media inside the battery module can easily flow out from the inlet and outlet, thus contaminating the environmental chamber and requiring manual cleaning. Utility Model Content

[0005] The technical problem this invention aims to solve is how to ensure the accuracy of battery module performance test results.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A battery module performance testing device includes a cabinet (1), an environmental temperature control mechanism (2), and a water cooling mechanism (3). The interior of the cabinet (1) is divided into an environmental chamber (11) and a unit chamber (12) by a partition (6). The partition (6) has multiple ventilation holes (61) on its upper surface and mounting holes (62) on its vertical plate. The environmental temperature control mechanism (2) is installed on the vertical plate of the partition (6) in the unit chamber (12) near the ventilation holes (61). The water cooling mechanism (3) is installed in the unit chamber (12). The output and input ends of the water cooling mechanism (3) are located in the mounting holes (62).

[0008] Beneficial effects: By setting up the cabinet, environmental temperature control mechanism, and water cooling mechanism, the cabinet is divided into an environmental compartment and a unit compartment by a partition. The environmental temperature control mechanism and the water cooling mechanism are then placed in the unit compartment. The environmental temperature control mechanism can normally introduce temperature-controlled airflow into the environmental compartment, while the coolant in the water cooling mechanism can be delivered to the battery module for its own temperature regulation. This makes the entire device more integrated and avoids the problem of the environmental compartment not being effectively sealed, thus ensuring the accuracy of the test results.

[0009] Furthermore, the environmental temperature control mechanism (2) includes an environmental temperature control unit (21) and an air guide hood (22).

[0013] Furthermore, a transparent observation window (41) aligned with the interior of the environmental chamber (11) is fixed on the sealed door (4), and a handle (42) is also fixed on the sealed door (4).

[0014] Beneficial effects: The transparent observation window and handle design allow inspectors to easily observe the dynamic scenes of the internal battery module during the simulated testing process, while the handle makes it easy for operators to open the sealed compartment door.

[0015] Furthermore, a first touch screen controller (7) and a second touch screen controller (8) are fixed on the cabinet (1). The first touch screen controller (7) is electrically connected to the ambient temperature control mechanism (2), and the second touch screen controller (8) is electrically connected to the water cooling mechanism (3).

Each of the liquid inlet pipes (32) is respectively connected and fixed to the output end and the input end of the water-cooling unit (31).

[0018] Beneficial effects: By setting up water-cooled units, infusion pipes, fixed connecting pipes, and flexible hoses, the heat exchange medium can be sent to the battery module for circulation, thereby achieving the temperature control effect of the battery module itself.

[0019] Furthermore, each of the hoses (34) is fixed with a connector and a valve at its end.

[0020] Beneficial effects: The design of connectors and valves facilitates the control of the flow of heat exchange medium in the hose and makes it easy to seal and connect it to the interface on the battery module.

[0021] Furthermore, a battery support mechanism (5) is fixed on the horizontal plate of the partition (6).

[0022] Furthermore, the battery lifting mechanism (5) includes a battery support plate (51), a spring (52), and a cylinder (53).

[0023] Beneficial effects: Through the configuration of the battery tray, spring, cylinder, and limit stop, during the battery module testing process, the battery module is placed on the upper surface of the battery tray with one end in contact with the limit stop. As the battery tray rotates and tilts around its connection point, the entire battery module remains stable, preventing any instability. After closing the valve on the hose, it can be directly removed from the battery module without any leakage of the cooling medium inside. Finally, by sealing the inlet and outlet of the cooling medium with a sealing plug, it can be directly removed from the environmental chamber. The entire process prevents leakage of the cooling medium, ensuring the cleanliness of the environmental chamber. The spring is used for the reset of the battery tray.
