Description

Technical Field

[0001] This application relates to the technical field of battery preparation devices, and particularly to a battery restraint tray. Background Art

[0002] Formation and grading are two essential processes in the latter stage of battery manufacturing. Formation means performing the initial charge and discharge on the battery to activate the internal chemical substances, and grading means sorting the battery by capacity.

[0003] In the formation process, the formation temperature mostly selected in the current industry is 45 - 70°C. The higher the formation temperature, the lower the viscosity of the electrolyte, the higher the conductivity of the electrolyte, and the faster the ion diffusion rate of the electrode material. Therefore, the higher the temperature, the smaller the polarization of the battery and the better the formation effect. However, too high a formation temperature will damage the structure of the already formed SEI film, increase side reactions, and accelerate the volatilization of low-boiling components in the electrolyte, which is not conducive to the formation effect. Moreover, since the battery itself has a certain internal resistance and generates heat, if this part of the heat cannot be dissipated in time, the heat accumulation will cause the battery to deform or even cause a fire.

[0004] In the grading process, the grading temperature mostly selected in the current industry is about 25°C. On the one hand, to ensure the test accuracy, because the electrical performance of the battery changes with temperature, in order to ensure the test accuracy, the temperature needs to be controlled. On the other hand, to ensure the safety and performance stability of the battery, because the battery will have safety hazards at too high or too low temperatures. Too high a temperature will lead to thermal runaway, and too low a temperature will cause damage to the internal structure of the battery. Whether the battery temperature is too high or too low will cause the battery performance to decline.

[0005] It can be said that the formation and grading processes to a certain extent determine the performance of the battery, and battery temperature control is particularly important in the formation process. In the formation and grading processes, a restraint tray is needed to group multiple batteries for transportation, transfer, and measurement. The structure of the tray plays a decisive role in battery heat dissipation. However, the current restraint trays used for battery formation and grading have poor heat dissipation performance, which will cause the temperature on the battery surface to be uneven. The temperature on the battery surface in contact with the tray is much higher than other surfaces of the battery, seriously affecting the battery performance.

[0006] Therefore, how to provide a restraint tray with good heat dissipation or heating effect to quickly adjust the battery is a technical problem that those skilled in the art urgently need to solve. Utility Model Content

[0040] As Figures 1 to 5 shown, this embodiment provides a battery restraint tray, including:

[0041] A frame, which is provided with at least one accommodation space inside;

[0042] At least two brackets 1, each of the brackets 1 is sequentially placed in the accommodation space. An accommodation groove 101 is provided in the middle of the bracket 1. Corresponding support portions 102 are provided on the adjacent side faces of each of the brackets 1. The adjacent two corresponding support portions 102 cooperate with each other to support the battery 3;

[0043] A liquid medium package 2, which is placed in the accommodation groove 101. The side face of the liquid medium package 2 is used to contact the battery 3. An inlet pipe 201 and an outlet pipe 202 are respectively provided on the liquid medium package 2;

[0044] Two medium pipes 4, the two medium pipes 4 are arranged in parallel on the frame. One of the medium pipes 4 is communicated with the inlet pipe 201, and the other medium pipe 4 is communicated with the outlet pipe 202.

[0045] The battery restraint tray provided in this embodiment, the bracket is detachably arranged in the frame. A battery is placed in the support part 102 between two adjacent brackets. The battery is clamped by the bracket. The surfaces of the liquid medium packages 2 in two adjacent brackets are in direct contact with the two side surfaces of the battery respectively for heat conduction. The contact area is large. A coolant medium at a constant temperature is introduced into the liquid medium package 2. The temperature of the battery can be quickly adjusted through the temperature of the coolant, so that the temperatures of the batteries in the restraint tray are uniform. The restraint tray has a good heat dissipation or heating effect on the battery, which helps to improve the performance of the battery. In the formation and grading process, the temperature of the battery is controlled by the liquid medium package 2, and there is no need to adopt the form of heating / dissipating heat for the whole press, which can reduce energy loss.

[0046] Among them, the battery is square, the bracket is cube-shaped as a whole, a square receiving groove 101 is arranged in the middle of the bracket, and the shape of the liquid medium package 2 is adapted to the shape of the receiving groove 101. An inlet pipe 201 is arranged at the lower part of one side of the liquid medium package 2, and an outlet pipe 202 is arranged at the upper part of the opposite side of the liquid medium package 2. The inlet pipe 201 and the outlet pipe 202 have a certain elasticity. The inlet pipe 201 and the outlet pipe 202 are preferably hoses. During the sliding process of the bracket in the frame, the inlet pipe 201 and the outlet pipe 202 can always be connected to the corresponding medium pipes 4. Through holes are respectively arranged on the two side surfaces of the bracket so that the inlet pipe 201 and the outlet pipe 202 can respectively pass through the corresponding through holes and be connected to the corresponding medium pipes 4. The medium pipes 4 are preferably made of stainless steel or heat-resistant plastic. As Figure 5 shown, the support part 102 includes two symmetrically arranged side plates. A bottom support is arranged at the lower side of the side plate, so that the receiving groove 101 is located between the two side plates. The bottom support is located at the lower side of the receiving groove 101. There is a step between the bottom support and the corresponding side plate. The battery is placed in the support part 102. The bottom support supports the bottom of the battery, and the two side plates on both sides can limit the two sides of the battery. The bracket and the liquid medium package 2 limit the other two sides of the battery, so that the battery is stably placed in the support part 102.

[0047] Preferably in this embodiment, as Figure 6 and Figure 7 shown, the liquid medium package 2 includes a bag, the bag is used to hold the coolant, and reinforcing ribs 203 are arranged on the side surface of the bag in contact with the battery 3. Convex bags 204 protruding outwards can be formed on the surface of the bag between the reinforcing ribs 203.

[0048] Specifically, the liquid medium bag 2 is made of rubber containing aluminum oxide, and has a high heat transfer coefficient. The two largest surfaces of the square bag are evenly provided with reinforcing ribs 203, which help to enhance the overall strength of the bag and maintain the overall square shape of the bag. The bag surface between the reinforcing ribs 203 forms ellipsoidal convex capsules 204, which are distributed on the two largest surfaces of the liquid medium bag 2. The shape and number of the convex capsules 204 can be determined according to the size of the liquid medium bag 2. The number of reinforcing ribs 203 is determined according to the number of convex capsules 204. The setting of the reinforcing ribs 203 is that the convex capsules 204 in two adjacent rows are staggered and evenly arranged, which can make the liquid medium bag 2 evenly stressed and prevent the liquid medium bag 2 from having a local bulging phenomenon, and can also increase the flow turbulence intensity of the coolant in the bag, so that the temperature distribution of each part of the liquid medium bag 2 is more uniform. The height of the convex capsule 204 is related to the degree of relative movement between the brackets 1, and does not exceed half of the relative movement distance between the two brackets 1. The convex capsule 204 on the surface of the liquid medium bag 2 is in contact with the surface of the battery 3 to conduct heat transfer, making the surface temperature of the battery 3 uniform. The convex capsule 204 ensures that when the restraint tray is working normally, the surface of the liquid medium bag 2 is not completely in contact with the surface of the battery 3, and there is a certain air gap between the two. Under long-term working conditions, the two will not stick together, making it easy to separate the liquid medium bag 2 and the battery 3.

[0049] This embodiment optimizes the above technical solution. Spoilers 205 are evenly arranged inside the bag, and the two sides of the spoiler 205 are respectively opposite to the inlet pipe 201 and the outlet pipe 202. Specifically, the spoiler 205 is fixed to the corresponding position of the inner wall of the bag. Preferably, the two sides of the spoiler 205 are respectively fixed to the reinforcing ribs 203 of the two opposite side walls of the bag. The spoiler 205 can not only cause the flow field inside the bag to be turbulent, but also support the bag, improve the overall strength of the liquid medium bag 2, and prevent the liquid medium bag 2 from having local bulging. Preferably, the spoilers 205 in two adjacent rows are staggered, and the spoilers 205 are evenly provided with through holes.

[0050] In this embodiment, in order to limit the relative movement distance between each bracket 1, as Figures 3 to 5As shown, corresponding limit blocks 103 are provided on the adjacent side faces of each bracket 1, and the corresponding limit blocks 103 cooperate with each other to limit the relative movement distance between adjacent brackets 1. Specifically, the limit block 103 is in an "L" shape, with one end fixed on the bracket 1 and the other end cooperating with the corresponding limit block 103. The two mutually cooperating limit blocks 103 are in opposite positions and are buckled with each other. The relative movement distance between them is the length of the side fixed on the bracket 1. The relative movement distance of the bracket 1 in the frame can be limited through the cooperation of the corresponding limit blocks 103. Preferably, four limit blocks 103 are provided on the adjacent side faces of each bracket 1, and the four limit blocks 103 are respectively arranged at the four corners of the bracket 1, so that the movement between the brackets 1 is more balanced and stable.

[0051] In this embodiment, regulating valves 401 are provided at positions corresponding to each inlet pipe 201 on the medium pipe 4. By controlling the opening degrees of the regulating valves 401, the flow rate of the coolant flowing into each package bag is controlled, and heat conduction heat exchange is continuously carried out between the liquid medium package 2 and the surface of the battery 3, so that the temperatures of the batteries 3 in the restraint tray are uniform. Thus, the batteries 3 are in the optimal formation and capacity temperature range. Preferably, regulating valves 401 are also provided at positions corresponding to each outlet pipe 202 on the medium pipe 4. More preferably, the connections between the inlet pipe 201 and the outlet pipe 202 and the corresponding regulating valves 401 are in a quick-connect manner, so that the bracket 1 together with the liquid medium package 2 is convenient for installation and disassembly, and thus the bracket 1 and the liquid medium package 2 are convenient for maintenance and servicing.

[0052] The structure of the above frame is described in this embodiment. The frame includes a front end plate 5, a front pressing plate 6, a rear pressing plate 7, and a rear end plate 8 arranged in sequence. A sliding rod 9 is fixedly arranged between the front end plate 5 and the rear end plate 8. A bottom plate 10 is arranged at the bottom between the front end plate 5 and the rear end plate 8. The front pressing plate 6 and the rear pressing plate 7 are respectively sleeved on the sliding rod 9, and the bottoms of the front pressing plate 6 and the rear pressing plate 7 are located on the bottom plate 10. The accommodation space is formed between the front pressing plate 6, the rear pressing plate 7, and the bottom plate 10;

[0053] The bracket 1 is detachably installed on the sliding rod 9 and is located between the front pressing plate 6 and the rear pressing plate 7, and the bottom of the bracket 1 is located on the bottom plate 10;

[0054] A restraint screw 11 is arranged between the front end plate 5 and the front pressing plate 6, and a pressure sensor 12 is arranged between the rear pressing plate 7 and the rear end plate 8. The restraint screw 11 is used to adjust the front pressing plate 6 so that the bracket 1 moves along the sliding rod 9.

[0055] Specifically, the frame is of a cuboid structure and is made of aluminum alloy, which is light in weight and high in strength. The bracket 1 is detachably mounted on the sliding rod 9 and can move along the axial direction of the sliding rod 9. One end of the restraint screw 11 is fixed on the front end plate 5, and the other end is connected to the front pressing plate 6. The distance between the front pressing plate 6 and the front end plate 5 can be adjusted through the restraint screw 11, so that the front pressing plate 6 pushes the bracket 1 and the liquid medium package 2 to move and clamp the battery 3. The pressure sensor 12 is used to sense and monitor the pressure for clamping the battery 3. Positioning holes are provided on the bottom plate 10. When the restraint tray reaches the press for formation and capacity grading, after the positioning holes on the bottom plate 10 are matched with the positioning mechanism of the press, the position of the battery 3 is positioned.

[0056] Preferably in this embodiment, as Figure 5 shown, there are two corresponding sliding rods 9. The sliding rods 9 are located in the upper part of the frame. Card slots 104 are respectively provided on both sides of the upper part of the bracket 1. The card slots 104 are used to be stuck on the corresponding sliding rods 9, and enable the bracket 1 to move along the axial direction of the sliding rods 9. Specifically, the card slot 104 is arc-shaped and is adapted to the shape of the sliding rod 9, so that the card slot 104 can be stuck on the sliding rod 9 and can move relative to the sliding rod 9. Card slots 104 are provided on both sides of the bracket 1. The cooperation between the card slots 104 and the sliding rods 9 can limit the positions of the left and right sides of the bracket 1, so that the bracket 1 can only move along the axial direction of the sliding rods 9.

[0057] In this embodiment, one end of the medium pipe 4 is blocked, and the other end is provided with a quick-connect one-way valve for quick-connect communication with an external infusion pipe. Specifically, both ends of the medium pipe 4 are respectively fixed on the front end plate 5 and the rear end plate 8, and the end of the medium pipe 4 provided with the quick-connect one-way valve passes through the rear end plate 8 for connection with the external infusion pipe. The connection method is quick-connect, which is convenient for connection. The medium pipe 4 is communicated with the external infusion pipe so that the coolant in the liquid medium package 2 can circulate to maintain a certain temperature. Preferably, a position sensor 13 is provided on the rear end plate 8. The position sensor 13 is used to sense the connection state between the medium pipe 4 and the external infusion pipe, so that the medium pipe 4 and the external infusion pipe are always in a connected state, thereby ensuring the reliable connection between the medium pipe 4 and the external infusion pipe. During the long-term operation process, the connection part between the medium pipe 4 and the external infusion pipe will not leak coolant.

[0058] Preferably, a coating is provided on the surface of the bracket 1. Specifically, a polytetrafluoroethylene coating or a ceramic coating is provided on the surface of the bracket 1.
