Description

Technical Field

[0001] This invention relates to the field of battery charging and discharging technology, and specifically to a zoned liquid-cooled temperature-controlled charging and discharging device. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage systems, and portable electronic devices, the application of secondary batteries such as lithium-ion batteries is becoming increasingly widespread. During their production, testing, and use, performance testing, aging cycles, and operational condition simulations are typically performed using charge-discharge equipment. During this process, the battery system experiences three main sources of heat: First, the battery itself generates heat during charging and discharging due to its internal resistance, especially under rapid or high-current conditions, resulting in significant temperature rise. Second, the contact resistance between the probes in the test circuit and the battery tabs or terminals also generates additional heat under the influence of current. Furthermore, the power modules inside the charge-discharge equipment, such as rectifiers, inverters, and control units, continuously generate heat during operation. If this accumulated heat cannot be dissipated in time, it will lead to excessively high battery temperatures, affecting the accuracy of battery test data and potentially causing thermal runaway, posing a safety risk.

[0003] Traditional charging and discharging equipment typically employs a uniform air-cooling or natural cooling method, making it difficult to achieve differentiated temperature control between the battery area and the power supply area. The battery area requires precise temperature control to ensure consistent testing conditions, while the power supply area needs effective heat dissipation to ensure system reliability. If the cooling requirements of both cannot be met separately, it can easily lead to a reduction in overall equipment energy efficiency and a decrease in system stability.

[0004] Furthermore, during the cooling process, condensation may form on the surface of the second or first temperature control module under low-temperature conditions. If the condensate cannot be collected and drained in time, it may drip onto the battery or electrical components, causing short circuits, leakage, or equipment corrosion, seriously affecting the safety and service life of the equipment.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This patent uses an isolation component to divide the internal structure of the device into a battery area and a power supply area, with each area equipped with an independent temperature control module. This design allows for differentiated temperature management for two areas with distinctly different heat source characteristics. The battery area ensures the battery operates within its optimal and stable temperature window during testing; the second temperature control module precisely controls the ambient temperature in this area, ensuring the accuracy and consistency of test data such as battery capacity and internal resistance. The power supply area ensures heat dissipation for the high-power power supply and drive components, preventing derating or damage due to overheating; the first temperature control module efficiently dissipates heat, ensuring continuous and stable high-power output. The isolation between the two areas prevents heat from the power supply area from interfering with the temperature control accuracy of the battery area, and also avoids the low-temperature requirements of the battery area increasing the burden on the power supply area's cooling system, thereby improving the overall energy efficiency and performance of the device.

[0019] This design incorporates a condensate drainage system to address the condensation issue on the temperature control modules. A condensate collection assembly is installed below the second temperature control module, which is most prone to condensation, reliably collecting all condensate dripping from its surface and preventing splashing. A drainage assembly connects to the condensate collection assembly at one end and extends to the outside of the equipment at the other, forming a drainage channel that reliably guides the collected condensate to a designated location outside the equipment. This avoids serious safety hazards such as short circuits, component corrosion, and electrical leakage caused by condensate buildup inside the equipment, protecting expensive internal electronic components and the tested batteries. It significantly improves the long-term operational reliability and safety of the equipment and reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] like Figures 1 to 14 As shown, this invention provides a partitioned liquid-cooled temperature-controlled charging and discharging device.

[0038] Example 1

[0039] like Figure 1 As shown, a partitioned liquid-cooled temperature-controlled charging and discharging device includes: a frame 1, the interior of which is divided into a battery area and a power supply area by an isolation component 2; a first temperature control module 3, which is installed in the power supply area; a second temperature control module, which is installed in the battery area; and a condensate system 5, which includes a liquid receiving component 52 and a drainage component 51; the liquid receiving component 52 is installed below the second temperature control module 4, one end of the drainage component 51 is connected to the liquid receiving component 52, and the other end of the drainage component 51 extends to the outside of the temperature-controlled charging and discharging device.

[0040] Specifically, this device achieves precise and safe environmental control of the battery and power system through three core design features: physical isolation, zoned temperature control, and condensate management. The isolation component 2 inside the rack 1 strictly divides the internal space into a battery area and a power area. This forms two independent environmental chambers, fundamentally preventing mutual interference between the two areas in terms of airflow, temperature, and potential risks. The first temperature control module 3 is used in the power area. Electrical components such as the charging and discharging power supply and control system in this area generate a large amount of heat during operation. The first temperature control module 3 is responsible for forced cooling of this area, ensuring the reliability and lifespan of electronic components and preventing malfunctions due to overheating. The second temperature control module 4 is used in the battery area. Its core task is to provide the optimal temperature environment for the battery's charging and discharging process. Whether cooling is required (e.g., preventing battery overheating during fast charging or in high-temperature environments) or heating is needed (e.g., preheating the battery in low-temperature environments to ensure performance and charging safety), this module can precisely regulate and ensure that the battery operates within an efficient and safe temperature window. Condensate will form on the surface of the second temperature control module 4 during cooling. The system actively collects this condensate through a wetted component 52, instead of allowing it to drip. The collected condensate is guided to the outside of the device through a drainage component 51 (such as a pipe or pump). This design ensures that the battery area remains dry, avoiding the risk of short circuits, corrosion, or leakage that may be caused by condensate buildup.

[0041] In a preferred embodiment, the fire protection system 6 includes a fire water inlet assembly 61 and a fire water contact assembly 62. One end of the fire water inlet assembly 61 is connected to an external fire water source, and the other end is connected to the fire water contact assembly 62 for discharging fire water. The fire protection system 6 also includes an automatic fire door, the activation signal of which is triggered by a fire alarm signal received by the power distribution / control box.

[0042] Specifically, the system is directly connected to an external fire water source via a fire inlet assembly. This external fire water source can be obtained through fire hydrants or dedicated fire pipelines, providing a continuous water supply for the system. Fire water is pre-delivered to the fire water receiving assembly 62, which is a built-in water storage container or collection tank. This ensures that the system has a reserve water source for firefighting immediately in the early stages of a fire, without waiting for the external water source. When the distribution / control box receives a fire alarm signal from the fire detection sensor, it immediately generates an activation signal upon confirmation of the fire. This signal triggers the automatic fire doors to close automatically, forming a physical firewall within the equipment. The core purpose of this firewall is to delay or prevent the spread of fire and smoke to other areas (especially adjacent batteries or electrical equipment), minimizing the fire's spread and buying time for subsequent firefighting measures.

[0043] In a preferred embodiment, the smoke exhaust system includes at least one of a unit smoke exhaust outlet and a centralized smoke exhaust outlet for discharging smoke to the outside of the frame 1. The maintenance doors include a remote control module maintenance door and a press maintenance door, which are communicatively connected to the power distribution / control box or have a safety interlock function.

[0044] Specifically, the smoke exhaust system employs a tiered, active smoke exhaust system. Each unit smoke exhaust outlet refers to a small smoke exhaust outlet independently configured for each battery module or specific heat source unit. Its principle is "proximity processing and source control." Once a unit experiences thermal runaway and triggers the fire suppression system, the nearest smoke exhaust outlet immediately activates after the fire suppression is completed, directly exhausting the smoke to prevent its spread within the unit. The centralized smoke exhaust outlet refers to the main smoke exhaust channel located at the top of rack 1. Its principle is collection and centralized discharge, gathering smoke generated by all unit smoke exhaust outlets or the entire battery area and discharging it uniformly outside the equipment. The remote control module maintenance door and press maintenance door establish a data link with the core power distribution / control box. When the maintenance door is opened, a signal is immediately sent to the control box. Its principle is to forcibly associate the physical state of the door (open / closed) with the equipment's power supply or high-voltage circuit. When the door is opened, the interlocking mechanism is immediately triggered, automatically cutting off the power to the relevant area (or preventing it from being powered on), ensuring that maintenance personnel cannot access live components.

[0045] Example 2

[0046] like Figure 2 As shown, the first temperature control module 3 includes: a first heat exchange component 31, an air duct structure 32, a fixing member 33, a first mounting base 34, an airflow drive component 35, and a first cable protection structure 36; the fixing member 33 is disposed in the air duct structure 32 for mounting the first heat exchange component 31; the first mounting base 34 is connected to the air duct structure 32 and / or the first heat exchange component 31; the airflow drive component 35 is mounted on the first mounting base 34, and its air outlet or air inlet communicates with the air duct structure 32 for driving airflow to circulate in the airflow channel formed by the air duct structure 32 and flow through the first heat exchange component 31; the first cable protection structure 36 is embedded in the first mounting base 34 for the wire harness of the airflow drive component 35 to pass through, providing protection.

[0047] Specifically, the first heat exchange component 31 is the core of temperature regulation (its internal refrigerant or liquid circulates for heat exchange with air). The airflow drive component 35 (fan or blower) provides power, forcing air to circulate within the closed channel formed by the duct structure 32. During this flow, the air must pass through the first heat exchange component 31 to be cooled. Fixtures are specifically designed to securely mount the heat exchange component inside the duct, ensuring it is in the optimal heat exchange position and withstands vibration. The first cable protection structure 36 is a critical safety design. It neatly embeds and secures the power supply harness of the airflow drive component 35 to the base, preventing harness damage and thus preventing short circuits or malfunctions.

[0048] like Figure 3 As shown, the second temperature control module 4 includes: a side temperature control component 41, which includes a second heat exchange component 411, a fixed bracket 412, a flow guiding structure 413, a second mounting base 414, a speed-regulating fan unit 415, and a second cable protection structure 416; the fixed bracket 412 is disposed within the flow guiding structure 413 and is used to install the second heat exchange component 411; the second mounting base 414 is connected to the flow guiding structure 413 and / or the second heat exchange component 411; the speed-regulating fan unit 415 is mounted on the second mounting base 414, and its air outlet or air inlet is connected to the air duct formed by the flow guiding structure 413 and the second heat exchange component 411, for driving airflow through the second heat exchange component 411; the second cable protection structure 416 is disposed on the second mounting base 414 at the position where the cable passes through, for sealing and protecting the cable of the speed-regulating fan unit 415.

[0049] Specifically, two sets of side temperature control components 41 are symmetrically arranged on the left and right sides of the battery area for precise cooling or heating of the battery cells. The second heat exchange component 411 is the core of heat exchange; the airflow guiding structure 413 works in conjunction with the second heat exchange component 411 to form an air duct that guides the airflow direction. This design ensures that the airflow can be precisely guided to the battery area that needs cooling / heating, avoiding airflow dispersion and short circuits, and ensuring heat exchange efficiency. The speed-regulating fan unit 415 can automatically adjust its speed (i.e., airflow) according to the real-time temperature feedback of the battery area. It operates at high speed when rapid cooling is needed and at low speed when only temperature maintenance is required, achieving precise on-demand control. Similar to the first temperature control module 3, all components are installed through the second mounting base 414 and the fixing bracket 412. The second cable protection structure 416 not only provides protection but also emphasizes the sealing function, preventing corrosive gases or fine particles that may be present in the battery area from entering the electrical connection parts, improving reliability under harsh operating conditions.

[0050] In a preferred embodiment, the speed-regulating fan unit 415 is located below the second heat exchange component 411; the flow guiding structure 413 is arranged around the second heat exchange component 411 in the circumferential direction, that is, the circumferential direction is around the second heat exchange component, and the flow guiding structure is a cover-shaped structure surrounding the second heat exchange component; its side is provided with an opening that allows airflow to pass through, forming an airflow path that draws air in from inside the battery area and discharges it outward after heat exchange.

[0051] Specifically, the variable-speed fan unit 415 is located below the second heat exchange assembly 411. When it operates, it generates a negative pressure (suction) below the second heat exchange assembly 411. This suction draws in the high-temperature air inside the battery area through the opening on the side of the guide structure 413, forcing it to pass through the fins of the second heat exchange assembly 411 from bottom to top. During this process, the air exchanges heat with the refrigerant inside the second heat exchange assembly 411, reducing its temperature. The cooled air is then blown out by the fan and guided by the guide structure 413, exiting horizontally or obliquely from the side opening, re-entering the battery area to cool the battery. This forms a closed-loop airflow path within the battery area: high-temperature air (from the battery) → drawn in through the side opening → flows upward through the second heat exchange assembly → cooled → exited from the side → cool air blown onto the tray assembly. The guide structure 413 ensures that the airflow follows this path efficiently and orderly.

[0052] like Figure 4 As shown, the airflow path of the first temperature control module 3 is configured as follows: under the drive of the airflow driving component, the airflow is drawn in from the internal space of the power supply area, flows through the first heat exchange component 31 for heat exchange, and then is guided through the air duct structure 32 and flows back to the internal space of the power supply area to form an internal circulating airflow; the airflow path of the second temperature control module 41 is configured as follows: under the drive of the speed regulating fan unit 415, the airflow is drawn in from the internal space of the battery area, flows through the second heat exchange component 411 for heat exchange, and then is guided through the opening on the side of the guide structure 413 and discharged to the outside of the frame 1.

[0053] Example 3

[0054] In a preferred embodiment, the temperature-controlled charging and discharging device further includes: a press device 7, which is installed in the battery area; and a power supply device 8, which is installed in the power supply area, wherein the press device 7 is electrically connected to the power supply device 8.

[0055] like Figures 6-7As shown, in a preferred embodiment, the power supply device 8 includes a power supply device frame 81, a heat dissipation duct structure 82, a conductive busbar component 83, a signal conversion component 84, and a pull-out guide mechanism 85; the power supply device frame 81 is slidably connected to the frame 1 through the pull-out guide mechanism 85.

[0056] The conductive busbar component 83 includes a busbar fixing plate 831 and a busbar 832. The busbar fixing plate 831 is fixed inside the power supply frame 81, and the busbar 832 is mounted on the busbar fixing plate 831. The heat dissipation duct structure 82 is installed between the conductive busbar component 83 and the signal conversion component 84. The heat dissipation duct structure 82 includes a plurality of heat dissipation fans 821, which are installed in the middle position of the power supply frame 81. The power supply frame 81 has a pull handle 811 on the front for pulling out the power supply 83.

[0057] Specifically, the press unit 7 is located in the battery area for battery testing. The power supply unit 8 (providing charging and discharging power) is located in the power supply area. The two are electrically connected via cables, achieving functional separation while maintaining collaborative operation. The entire power supply unit 8 is slidably connected to the frame 1 via a pull-out guide mechanism 85. Operators can smoothly slide the entire power supply unit 8 out of the frame 1 like a drawer by pulling the front pull handle, fully exposing it for easy wiring, maintenance, or replacement. A quick-locking mechanism 812 automatically or manually engages after the power supply unit 8 is pushed into place, firmly securing it within the frame 1 to prevent accidental slippage during transport or operation, ensuring reliable electrical connections and equipment safety. Conductive busbar components 83 (busbar fixing plates 831 and busbar 832) replace the tangled cables for transmitting high currents and connecting internal components, offering advantages such as low resistance, high reliability, and a neat layout. The heat dissipation duct structure 82 and its heat dissipation fan 821 are arranged between the high-heat-generating conductive busbar component 83 and the signal conversion component 84, forming a highly efficient cooling duct that can directly and effectively remove the heat generated by the critical heat source, ensuring that the power supply operates at the optimal temperature. The power isolation plate 86 is installed at the bottom to isolate the heat generated by the power supply device 8 during operation from downward transfer, protecting the equipment or cables below, and also playing a certain role in fire protection.

[0058] In a preferred embodiment, the pull-out guide mechanism 85 includes a pair of side rails 851 and a guide wheel set 852; the side rails 851 are mounted on both sides of the frame 1; the guide wheel set 852 is mounted on the bottom of the power supply frame 81 and rolls in cooperation with the side rails 851.

[0059] Specifically, the pull-out guide mechanism 85 is a precision mechanical guide system based on the principle of rolling friction. Its core principle is to transform the sliding friction between the heavy power supply unit and the frame 1 into rolling friction through the cooperation of "rail-roller," thereby achieving a labor-saving, smooth, and linear pull-out movement. Pairs of side rails 851 are fixedly installed on both sides of the frame 1, serving as fixed and precisely parallel guide rails. Guide wheel sets 852 are installed at the bottom of the power supply unit frame 81. The rollers in the wheel sets are precisely embedded in the grooves of the side rails 851, forming a fit.

[0060] When maintenance is required, the operator pulls the handle on the power supply unit 8 to apply a pulling force. This force is transmitted through the frame to the guide wheel assembly 852, which drives the rollers to roll in the grooves of the side rails 851, thereby guiding the entire power supply unit 8 smoothly out of or into the frame 1 along a preset straight path.

[0061] In a preferred embodiment, the power supply frame 81 further includes a quick-locking mechanism 812, which includes a locking block 8122 and a locking pin 8121; the locking block 8122 is fixed to the pull-out guide mechanism 85; and the locking pin 8121 engages with the locking block 8122.

[0062] Specifically, the locking block is fixedly installed on the pull-out guide mechanism 85 (such as the side rail 851) or the frame 1, with its position precisely calculated to correspond to the power supply unit 8 being fully pushed into place. The locking pin 8121 is installed on the power supply unit frame 81. When the operator pushes the power supply unit 8 fully into the frame 1 along the pull-out guide, the locking pin 8121 on the frame will automatically align and engage with the locking block fixed on the guide (usually achieved through a spring-loaded inclined plane or hook-like structure), forming a mechanical interlock to prevent the frame from moving accidentally.

[0063] In a preferred embodiment, a power isolation plate 86 is installed at the bottom of the power device frame 81 to insulate the power device 8 from heat.

[0064] Specifically, the power isolation plate 86, as a physical barrier made of heat-insulating material, is installed at the bottom of the power device frame 81, located between the heat-generating power device 8 and the isolation component 2.

[0065] Example 4

[0066] In a preferred embodiment, such as Figure 5As shown, the press device 7 includes a bottom frame assembly 71, an upper frame body 72, a main column 73, an upper power assembly 74, a tray assembly 77, two end electrode probe module mechanisms 752, and a top electrode probe module mechanism 751. The main column 73 is vertically fixedly installed on the bottom frame assembly 71. The upper frame body 72 is installed above the main column 73. The upper power assembly 74 is disposed on the upper frame body 72 and is used to drive the top electrode probe module mechanism 751 to move up and down along the main column 73. The top electrode probe module mechanism 751 is connected to the output end of the upper power assembly 74 and is located below the upper frame body 72. The two end electrode probe modules 752 are respectively installed on the left and right ends of the bottom frame assembly 71. The tray assembly 77 is disposed on the bottom frame assembly 71 and is used to carry the battery.

[0067] Specifically, the bottom frame assembly 71 serves as the base platform. The main column 73, as the core guide column, together with several auxiliary columns 76, forms a three-dimensional frame, providing precise and stable guidance and support for the lifting and lowering movement of the upper frame body 72, preventing lateral swaying. The upper power assembly 74 (electric cylinder / pneumatic cylinder / hydraulic cylinder) serves as the power source and is installed on the upper frame body 72. After receiving control signals, it drives the entire upper frame body 72 to perform vertical lifting and lowering movements along the main column 73 and auxiliary columns 76, thereby providing precisely controllable downward pressure. The electrode probe module 75 includes two end electrode probe module mechanisms 752 and a top electrode probe module mechanism 751. When the battery placed in the tray assembly is a prismatic battery, the top electrode probe module presses down to charge and discharge the battery; when the battery placed in the tray assembly is a blade battery, the two end electrode probe modules press together to charge and discharge the battery. The tray assembly 77 is used to quickly and accurately position and carry the battery under test. Cable clip 78 is used to organize and secure cables connected to the upper moving parts, preventing them from being pulled, worn, or interfering with the operation of the equipment during movement.

[0068] In a preferred embodiment, a cable clip 78 is disposed on the upper frame body 72 for constraining and guiding the cable.

[0069] In a preferred embodiment, the upper power assembly 74 is one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0070] Example 5

[0071] In a preferred embodiment, such as Figures 8-9As shown, the top electrode probe module mechanism 751 includes: an upper probe module frame 7511, a lifting guide assembly 7512, a horizontal adjustment assembly 7513, at least one set of probe modules 7514, and a limiting assembly 7515; the lifting guide assembly 7512 is mounted on the upper probe module frame 7511 and is used to connect to the upper power assembly 74 to realize the vertical lifting of the top electrode probe module mechanism 751; the horizontal adjustment assembly 7513 includes a guide rail component disposed on the upper probe module frame 7511; the probe modules are disposed on the guide rail component and can be steplessly adjusted in position along the battery electrode spacing direction; the limiting assembly 7515 is used to limit the lifting stroke of the top electrode probe module mechanism 751 to accommodate batteries of different heights.

[0072] Specifically, the lifting guide assembly 7512, as the main body of the mechanism, is directly connected to the upper power assembly 74 above, responsible for converting power into precise and stable vertical linear motion to ensure that the probe can vertically press against the battery terminals. The guide rail component of the horizontal adjustment assembly 7513 is mounted on the main frame. The probe module 7514 is mounted on the guide rail as an independent unit, and the operator can manually or automatically slide it along the guide rail to continuously and steplessly adjust its fixed position in the horizontal direction (i.e., the direction of battery terminal spacing) to accommodate the terminal spacing of batteries of different sizes. The limiting assembly 7515 is located at the end of the lifting path. Its function is to set a mechanical hard stop point to prevent the power assembly from traveling excessively when pressing down, thereby protecting batteries of different heights from being excessively squeezed and damaged.

[0073] In a preferred embodiment, the lifting guide assembly 7512 includes a guide shaft 7512.1, a guide shaft connecting plate 7512.2 that cooperates with the guide shaft 7512.1, a guide shaft seat 7512.3, and a linear bearing 7512.4. The linear bearing 7512.4 is inserted into the guide shaft 7512.1 and located between the upper probe module frame 7511 and the upper frame body 72. The guide shaft 7512.1 and the linear bearing 7512.4 cooperate to realize the lifting movement. The guide shaft connecting plate 7512.2 is installed at the end of the guide shaft 7512.1.

[0074] Specifically, the guide shaft 7512.1, acting as a precise track, is rigidly fixed at both ends to the upper frame body 72 via guide shaft connecting plates 7512.2, forming a fixed reference. A linear bearing 7512.4 is pressed into the upper probe module frame 7511 and inserted into the guide shaft 7512.1. The balls or rollers inside the linear bearing 7512.4 transform the friction between it and the guide shaft 7512.1 into rolling friction. When the upper power assembly 74 is driven, the entire upper probe module frame 7511 moves in an extremely smooth and undulating vertical linear motion along the fixed guide shaft 7512.1 via the linear bearing 7512.4.

[0075] In a preferred embodiment, the transverse guide rail component 7516 includes a transverse sliding groove 7516.1, a slide rail 7516.3 adapted to the transverse sliding groove 7516.1, and a slider 7516.2 cooperating with the slide rail 7516.3. The probe module 7514 is mounted on the transverse sliding groove 7516.1 via the slider 7516.2.

[0076] Specifically, the transverse slide rail 7516.1 serves as a fixed base track and is mounted on the module frame. The slide rail 7516.3 is precisely fitted and installed with the transverse slide rail 7516.1. The probe module 7514 is directly mounted on the slider 7516.2. By driving the slider 7516.2, the entire probe module 7514 can be moved smoothly along the slide rail 7516.3 (i.e., the direction of the battery terminal spacing), thereby precisely adjusting its left and right positions.

[0077] In a preferred embodiment, at least one side of the transverse guide rail component 7516 is provided with a scale 7516.4 for indicating the left and right positions of the probe module 7514.

[0078] In a preferred embodiment, the probe module 7514 includes at least one of a positive electrode probe module 7514.1, a temperature probe module 7514.2, and a negative electrode probe module 7514.3, and each type of probe module can be independently adjusted laterally.

[0079] In a preferred embodiment, the limiting component 7515 includes a limiting flange seat 7515.1, a limiting screw 7515.2, a limiting nut 7515.3, and an upper limiting block 7515.4; the limiting component 7515 is adapted to the upper power component 74751; the limiting flange seat 7515.1 is fixed to the upper probe module frame 7511, and the limiting screw 7515.2 passes through the limiting flange seat 7515. 1. A limiting nut 7515.3 that cooperates with the limiting screw 7515.2; by screwing the limiting nut 7515.3 or adjusting the extension length of the limiting screw 7515.2, the lower limit position of the top pole probe module mechanism 751 is mechanically limited; the upper limiting block 7515.4 passes through the limiting screw 7515.2 and is located between the upper probe module frame 7511 and the upper frame body 72.

[0080] Specifically, the limiting flange seat 7515.1 is fixed to the upper probe module frame 7511, serving as the mounting base for the entire assembly. The limiting screw 7515.2 passes through the limiting flange seat 7515.1. The limiting nut 7515.3 is threaded into the limiting screw 7515.2. By tightening the limiting nut 7515.3, the extension length of the limiting screw 7515.2 relative to the limiting flange seat 7515.1 (i.e., relative to the moving upper probe module frame 7511) can be precisely changed. The upper limiting block 7515.4 is fixed to the upper frame body 72 and passes through the limiting screw 7515.2. When the upper probe module frame 7511 moves downward, the top of the adjusted limit screw 7515.2 will eventually abut against the upper limit block 7515.4. Since the upper limit block 7515.4 is fixed, the movement is mechanically stopped, thereby limiting the lower limit of the stroke.

[0081] Example 6

[0082] In a preferred embodiment, such as Figure 11 As shown, the bottom frame assembly 71 includes a base 711, a guide and positioning mechanism 712, an electrical connector group 713, a foolproof mechanism 714, and a bottom temperature control assembly 42. The guide and positioning mechanism 712 is disposed on the base 711 and is used for coarse and fine positioning of the battery tray placed on the base 711. The foolproof mechanism 714 is disposed on the base 711 and is used to detect the placement status of the battery tray. The electrical connector group 713 is disposed on the base 711 and is used to establish an electrical connection with the battery terminals on the positioned battery tray. The bottom temperature control assembly 42 is installed on the base 711 and is located at the bottom of the tray assembly 77, and is used to dissipate heat evenly to the batteries on the positioned battery assembly.

[0083] Specifically, the guiding and positioning mechanism 712 is integrated into the base 711 and typically includes a coarse guide component 7121 and a positioning component 7122. When the operator pushes in the battery tray, the coarse guide component 7121 first guides the tray into approximate position, and then the positioning component 7122 precisely fixes it in the preset position, ensuring that the battery terminals are strictly aligned with the electrical connector assembly 713. A foolproof mechanism 714 is used to detect whether the tray is placed in place and locked. Its signal is transmitted to the equipment control system, and only after receiving the "correct placement" signal will the system allow subsequent pressurization and charging / discharging operations, fundamentally preventing misoperation. The position of the electrical connector assembly 713 (typically a high-current socket or probe array) precisely corresponds to the battery terminals on the precisely positioned battery tray. Once the tray is positioned, the battery terminals automatically establish a reliable electrical connection with the electrical connector assembly 713. The bottom temperature control component 42 is installed inside the base 711; it is responsible for cooling the bottom surface of the battery and, in conjunction with the side and top temperature control systems, achieves uniform temperature control of the battery from all directions.

[0084] In a preferred embodiment, the guiding and positioning mechanism 712 includes a coarse guiding component 7121 and a positioning component 7122; the coarse guiding component 7121 is used to initially limit the position of the pallet assembly 77; and the positioning component 7122 is used to finally limit the position of the pallet assembly 77 after the coarse positioning.

[0085] Specifically, the coarse guide assembly 7121 accommodates larger initial positional deviations. When the operator places the pallet, the coarse guide assembly 7121 first contacts the corresponding structure on the pallet assembly 77, automatically correcting the pallet to a roughly correct, near-target position using the guiding action of the inclined or conical surface. After the coarse positioning guides the pallet to the target area, the positioning assembly 7122 begins to operate. Its minimal clearance eliminates any remaining minor deviations after coarse positioning, precisely pulling or pushing the pallet into its final working position.

[0086] In a preferred embodiment, the coarse guide assembly 7121 includes a first guide plate 7121.1 arranged along a first direction and a second guide plate 7121.2 arranged along a second direction perpendicular to the first direction.

[0087] Specifically, the first guide plate 7121.1 is arranged along a first direction (e.g., the X-axis), and its guide surface is used to restrict movement in the tray direction. The second guide plate 7121.2 is arranged along a second direction perpendicular to the first direction (e.g., the Y-axis), and its guide surface is used to restrict movement of the tray in that direction. When the operator places the battery tray, the two adjacent outer edges of the tray will contact the guide surfaces of the first guide plate 7121.1 and the second guide plate 7121.2, respectively. These two perpendicular plates work together to automatically guide and constrain the tray within a preset range with small tolerances, completing coarse positioning.

[0088] In a preferred embodiment, the positioning component 7122 includes a pin-shaped component 7122.1 that can be inserted into a corresponding positioning hole of the tray component 77.

[0089] Specifically, the positioning component 7122 is based on a pin-hole mechanical interlocking mechanism. It uses a pin-shaped component 7122.1 (such as a positioning pin) mounted on the base 711 to precisely insert into the corresponding positioning hole pre-set on the bottom of the battery tray. By utilizing the extremely small fit tolerance between the two, translational degrees of freedom in all directions are eliminated, thereby achieving the final precise positioning of the tray in the X and Y directions in the horizontal plane.

[0090] In a preferred embodiment, the foolproof mechanism 714 includes a foolproof pin 7141 for engaging with an asymmetrical structure on the tray assembly 77 to determine its orientation.

[0091] Specifically, the mis-locking mechanism 714 is based on a mechanical shape interlock. It uses a fixed-position and-shape mis-locking pin 7141 on the base 711. This pin 7141 can only match and pass through specific asymmetrical structures (such as grooves, notches, or asymmetrically arranged holes) on the battery tray in the single correct orientation. If the tray is mis-oriented or of the wrong type, its asymmetrical structure cannot align with the mis-locking pin 7141, and the tray assembly 77 will be physically blocked by the pin 7141 and cannot be placed in place.

[0092] In a preferred embodiment, the system further includes a driving mechanism 715 and a limiting mechanism 716. The driving mechanism 715 is used to drive the two-end pole probe module mechanism 752 to clamp the tray assembly 77, and the limiting mechanism 716 is used to limit the stroke of the two-end pole probe module mechanism 752.

[0093] In a preferred embodiment, a position sensor 717 is used to detect whether the two-end pole probe module mechanism 752 is pressed into place.

[0094] Example 7

[0095] In a preferred embodiment, such as Figures 10-11 As shown, the two-terminal probe module mechanism 752 includes a probe assembly, a temperature probe mounting strip 7522, a probe mounting plate 7523, an adjustment mechanism, a support structure 7525, and a side cylinder adapter plate 7526. The probe assembly includes a temperature probe and a current / voltage probe. The current / voltage probe is mounted on the probe mounting plate. The temperature probe is mounted on the temperature probe mounting strip 7522, and the temperature probe mounting strip 7522 is fixed to the probe mounting plate. The adjustment mechanism 7524 includes a positioning strip 7524.1 and an adjusting screw assembly 7524.2 located on the support structure 7525, used to adjust the spacing and height of the probe assembly. The support structure 7525 includes a probe base plate 7526. 525.1, several support suspension plates 7525.2, module base plate 7525.3, side upright plates 7525.4, and support upright plates 7525.5; the probe assembly is mounted on the probe base plate via a shim plate; several support suspension plates 7525.2 are equidistantly mounted on the probe base plate 7525.1, and guide suspension plates are mounted on the support suspension plates 7525.2 at both ends; the side upright plates 7525.4 and support upright plates 7525.5 are fixed on the module base plate 7525.3 to support the entire two-end pole post probe module mechanism 752; the two-end pole post probe module mechanism 752 is connected to an external drive mechanism via the side cylinder adapter plate 7526 and is provided with a limit stop for position restriction.

[0096] Specifically, temperature and electrical parameter detection functions are integrated into an adjustable probe assembly through a rigid support frame, and its precise movement is driven by a drive mechanism to achieve automatic docking, reliable contact and accurate measurement with the battery terminals.

[0097] The probe assembly is a core functional component, integrating temperature probes (for monitoring terminal temperature) and current / voltage probes (for charging / discharging and signal acquisition), enabling simultaneous monitoring of electrical performance and thermal management. The adjustment mechanism 7524 (positioning bar 7524.1 and adjusting screw assembly 7524.2) allows for fine, stepless adjustment of the overall spacing of the probe assembly to accommodate different battery sizes and heights, ensuring optimal contact between all probes and terminals. The probes, support suspension plate 7525.2, module base plate 7525.3, side upright plate 7525.4, and support upright plate 7525.5 form a robust, rigid frame, ensuring the probe assembly operates without wobbling during movement and pressing. The bottom slide rail engages with the linear guide rail on the base 711, providing precise, low-resistance guidance for the opposing movement of the entire module. The entire module is connected to a drive mechanism (such as a cylinder) via a side cylinder adapter plate 7526, enabling automated clamping and releasing. The limit stop 7527 mechanically limits its maximum stroke to prevent overload.

[0098] In a preferred embodiment, the two-terminal probe module mechanism is used for blade battery cell testing. This mechanism integrates current and voltage probes with temperature probe mounting strips on a probe mounting plate, enabling simultaneous electrical connection and temperature monitoring of the two-terminal battery. An adjustment mechanism, through the cooperation of positioning strips and adjusting screw assemblies, allows for fine-tuning of the entire probe assembly in terms of spacing and height, ensuring precise alignment and reliable contact between the probes and the battery terminals. The support structure is based on the module base plate, providing stable support through side uprights and support uprights. The probe base plate is connected to the module base plate through several equidistantly distributed support suspension plates, with guide suspension plates at both ends further enhancing structural rigidity and motion guidance. The entire module is connected to an external drive mechanism via a side cylinder adapter plate, enabling lateral movement and positioning by limit stops.

[0099] Example 8

[0100] In a preferred embodiment, such as Figures 13-14 As shown, the tray assembly 77 includes a universal outer frame 771 and a replaceable inner liner. The universal outer frame 771 contains an inner liner component, which includes a top terminal battery liner 772 and two end terminal battery liners 774. The top terminal battery liner 772 is used to accommodate a top terminal battery 773; the two end terminal battery liners 774 are used to accommodate two end terminal batteries 775. The top terminal battery liner 772 or the two end terminal battery liners are connected to the universal outer frame 771 via snap-fit ​​or positioning pins. The bottom of the universal outer frame 771 has a heat dissipation groove for the temperature-regulating cooling system to dissipate heat from the batteries inside the universal outer frame 771. Openings are provided on both sides of the universal outer frame, and the positions of these openings are adapted to the two end terminal probe module mechanism 752.

[0101] Specifically, a standardized universal frame 771 provides a unified structure, heat dissipation, and interface function. By replacing the internal dedicated "replaceable liners," it can quickly adapt to battery models with different terminal post layouts, thus enabling a single tray system to meet various battery testing needs. The universal frame 771 serves as the load-bearing base, with openings on both sides precisely corresponding to the end terminal post probe module mechanisms, ensuring accurate probe insertion. Internally, different dedicated replaceable liners—for top terminal post batteries or end terminal post batteries 775—are secured using quick-connect methods such as snap-fits or positioning pins, physically defining and supporting batteries of different sizes and structures. The heat dissipation grooves at the bottom of the universal frame 771 provide a direct heat exchange channel for the bottom frame assembly's temperature distribution system, allowing cool or hot air to be transferred to the batteries within the tray assembly 77. The openings on both sides ensure that regardless of the type of liner installed, the probes of the end terminal post probe module mechanism 752 can pass unimpeded through the universal frame 771 and accurately contact the terminals on both sides of the battery.
